What Are The Pitfalls Of Solar Street Lamp Procurement?

Today, solar street lamps are widely used, but now the solar street lamp market price varies, solar street lamp manufacturers produce uneven quality. It is inevitable that some manufacturers will hype up their own products, but the quality of the product has brought a significant bad impact, so when purchasing solar street lights, we should pay attention to avoid falling into the trap given by the manufacturer, so, what is the trap that solar street lights purchase need to pay attention to?

1, counterfeit chips, low-end chips

The core of LED lamp is the chip, which directly determines the performance of the lamp! However, some bad manufacturers take advantage of customers’ unprofessionalism and use low-cost chips to make customers buy low-quality products with high unit price, resulting in direct economic losses and serious hidden dangers to the quality of LED lamps.

2. Configure virtual tags and exaggerate configuration parameters

The hot  LED street lighting  is also accompanied by the reduction of price and profit, the fierce competition has also led to many solar street lamp manufacturers began to cut corners and falsely label product parameters, the wattage of theLED solar outdoor light source, the wattage of the solar panel, the capacity of the battery, and even the material used in the solar lamp pole have problems. Of course, this is also caused by the customer’s repeated comparison of prices and demand for low prices, and it is also related to the practices of some manufacturers.

3. Poor heat dissipation design and unreasonable configuration

In the aspect of heat dissipation design, the PN junction temperature of LED chip increases by 10 degrees, and the life of semiconductor devices will decrease by multiple. Due to the high brightness requirements of LED solar street lights, the use of the environment is harsh, if the heat dissipation is not solved well, it will quickly lead to LED aging, stability reduction. In addition, unreasonable configuration often leads to the specific use situation can not reach the expected value.

4. Copper wire impersonating gold wire and controller problems

Many LED manufacturers are trying to develop alternatives such as copper alloy, gold-covered silver alloy wire, and silver alloy wire to replace expensive gold wire. Although these alternatives are superior to gold wire in some characteristics, they are much less stable in terms of chemical stability, for example, silver wire and gold-covered silver alloy wire are susceptible to sulfur/chlorine/bromine corrosion, and copper wire is susceptible to oxidation vulcanization. For encapsulated silica gel similar to absorbent breathable sponge, these alternatives make the bonding wire more vulnerable to chemical corrosion, the reliability of theLED solar outdoor light source is reduced, the use of a long time, LED beads are more likely to break the wire dead lamp.

Integrated Solar Street Lamp And Split Solar Street Lamp Structure And Advantages And Disadvantages Comparison!

Integrated solar street lamp and split solar street lamp belong to two different structures, they have their own advantages and disadvantages, in the selection, we must have a full understanding of the structural performance of the two, so as to choose the right type of street lamp according to the needs, the following is the structure and advantages and disadvantages of integrated solar street lamp and split solar street lamp comparison!

Structural comparison between integrated solar street lamp and split solar street lamp:

Integrated solar street lamp is relative to the split solar street lamp. Simply put, the battery, controller and LED light source are concentrated into one, made into a lamp head, and then configured with panels, lamp poles or arm installation. It is characterized by convenient installation, can be said to be a fool installation, will screw will be installed, removed from the traditional split solar street need to install the panel bracket, install the lamp head, make the battery pit and other steps, greatly saving labor costs and construction costs.

In terms of performance, integrated solar street lamps have been upgraded in terms of design performance, such as batteries. Now most street lamp batteries are installed with lithium batteries, which are much higher than traditional street lamp batteries in terms of performance.

Integrated solar street lamp

Comparison of advantages and disadvantages of integrated solar street lamp and split solar street lamp:

1, the advantages of integrated solar street lamp, on the one hand, is easy to install and use, customers can in the absence of any professional knowledge, simply install a few screws according to the instructions, fixed the product can be used, very convenient and save the installation cost.

2, the price advantage is obvious, the integrated solar street lamp because of the design reason, the panel power and battery capacity is generally relatively small, the cost is relatively low. More because it saves the cost of installing the fixed bracket of the panel, the cost of the battery box and so on, compared with the split solar street lamp, the price is relatively lower. His application occasions are not too high lighting requirements, in contrast, the price advantage is very obvious. Usually, the price of split street lamps is about 40% to 60% more expensive than integrated solar street lamps.

3, Split solar street light adopts the separate design of panel, battery and LED lamps. According to the requirements of lighting occasions, the required power of led street light can be calculated, with the power optional range of 20W-120W to meet the requirements of different customers. And according to the requirements of LED street lamp, suitable power panels and batteries can be adapted, which can not only ensure the service life of LED street lamp, but also because the conventional battery and intelligent controller is placed at the bottom of the light pole, convenient maintenance and replacement, saving the later maintenance cost.

4, split solar street lamp maintenance is much more complex, when there is damage, the manufacturer needs to send technicians to the local maintenance, maintenance needs to be from the battery, photovoltaic panel, LED lamp, wire and other troubleshooting; All-in-one solar street lamps just need to be unloaded and sent back to the factory.

Split solar street lamp

5, In terms of the scope of use, according to the technical parameters, split solar street lights are generally mainly used in large roads, highways and other places with high demand for lights, while integrated solar street lights can be used in streets, communities, factories, rural areas, county streets, village streets and other places.

6, in terms of technical parameters, split solar street technical parameters can be from 10-80W or even higher, such as: new rural solar street series, in the configuration, according to the wattage, rainy days and other technical parameters to the corresponding configuration of battery, photovoltaic panel size, controller, but also need to adjust the photovoltaic panel irradiation Angle according to the actual installation; Integrated solar street lamps now generally have several wattage of 10w, 20w, 30w and 40w, each of which is the best configuration based on a long time experiment, such as 3-6 meters 20W new rural solar street lamps.

The above is the structure and advantages and disadvantages of integrated solar street lamp and split solar street lamp. It is not difficult to find that the two have great differences in component structure, price, range of use, installation and maintenance methods, technical parameters and other aspects, but each has its own advantages.

The Invention That Changed The Lighting Industry

Back in 2014, the Nobel Prize in Physics was awarded to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura – the creators of the blue light emitting diodes, also known as LEDs. The winners will join a prestigious list of 196 other Physics laureates for their invention that has illuminated the 21st century.

A century ago, people used to illuminate their houses with kerosene lamps or candles, and they all got shocked with Thomas Edison’s invention of the incandescent lamps in the 1880s. Even though that they served as a perfect source of light, they weren’t energy efficient at all.

The search for an energy saving alternative was the focus of every lighting development ever since. It looked like that nothing could replace incandescents from the American households until the appearance of the LED lights.

Back in 1862, the first LED lights were introduced, but they glowed only in the infrared range, which made them suitable for a small array of products such as digital clocks and indicator lamps. Creating a LED light that glowed in white light was a difficulty that took around thirty years for scientists to overcome.

The first bright blue LED was revealed in 1993 by Shuji Nakamura, who built on the work of his colleagues – Akasaki and Amano. Now, LED lights are gaining an immense popularity as they are being used for cellphones lights, table lamps, traffic signals, computers and almost everything that requires energy-efficient light. The white LED lamps are highly used in offices as they consume much less energy than the traditional ways of illumination.

As competition grows, the prices of this new technology fall and become even more affordable to consumers.

Every time scientists unveiled a new light source, people declared that incandescent lights are becoming a thing of the past. However, it took more than a century for an alternative to beat its predecessor!

Unlike incandescent bulbs, LEDs convert electricity into photons instead of turning it into a mixture of heat and light.

Unlike incandescent bulbs, LEDs convert electricity into photons instead of turning it into a mixture of heat and light.

During the awarding, the Nobel committee said that incandescent lamps lit the 20th century, while LED lights will light the 21st century. In fact, around 20% of the world’s electricity is used for lighting and the LED technology could reduce that amount to 4%. Moreover, they can run on solar power, which means that they can help more than 1.5 billion people who don’t have access to electricity.

If you are looking to invest in the future, then you might want to replace the traditional lighting in your house with a more futuristic technology such as the LED bulbs.

What should know about LED

Are your old incandescents burning out one after another? Then it might be time to consider a more advanced technology such as the LED. LEDs are the future of the lighting industry as they can have a lifespan of up to twenty-five years and they are energy-efficient.

However, there are many varieties of the LED lights and choosing one depends on few factors. Here’s what you need to know before heading to the store.

Lumens replace watts

When shopping for incandescent bulbs, people used to look at the watts to determine how bright the lamp is. However, the brightness of the LEDs is determined by lumens as they draw far less energy than traditional bulbs.

To make a comparison, 60W incandescent bulb is going to be around 8-10 watts for a LED Bulb. That’s where lumens come to the rescue.

A lumen (lm) is a measurement of brightness for a LED light bulb, and it is what you should be looking at when purchasing lights.

Choosing the right color LED

Incandescents provide a warm yellow color that’s perfect for homes, whereas LEDs come in a variety of colors – from purple to red. Moreover, there are even different types of white and yellow.

If you are looking for a color that is suitable for your home, then you might want to consider “warm white,” “soft white” or “bright white.”

The first two will provide a yellow-like color that’s similar to incandescents, while the “bright white” color is close to the one we see in retail stores and it resembles the daylight.

Look at the kelvins of the light bulb when buying one. The lower the number is, the warmer the light will be. If you are looking for an incandescent color, then you will need something between 2,500-3,500 kelvins.

Replacing the old lights with LED bulbs should be considered as a long-term investment. They are much more expensive than traditional ones, but their prices have decreased due to the large competition in the industry.

Even though that you have to pay more upfront, the LED bulb will pay off throughout the years as they have a longer lifespan and consume much less energy than others.

Some fixtures aren't compatible with LEDs

You must ensure that the place you want to put the LED bulb is suitable or else it might kill it faster. Many people believe that LEDs don’t produce heat, but they do. However, it is pulled away from the bulb into the air and this way the bulb stays cool, preserving its life expectancy.

Nevertheless, if the light bulb is enclosed, the heat won’t be able to escape, which would result in a shorter lifespan. However, there are LED bulbs that are especially approved for enclosed spaces.

The benefits of LED Lights

Currently, the award-winning LED Lights are considered as the most efficient and cost-effective way to illuminate your property. The light emitting diodes are by far the most eco-friendly way of illumination, and the provided benefits are not only for us humans but the whole planet.

Here are the top benefits of the LED Lighting:

I. Longer life expectancy

One of the biggest benefits of this new technology is the provided lifespan of LED lights. Studies show that a single bulb can operate up to 100.000 hours or for up to 25 years. In fact, if you leave a LED fixture to work for 8 hours a day, it will be operational for the next two decades.

Unlike standard lights that burn out, LEDs become less bright when they are being used over an extended period of time, but they continue to work.

II. Energy-efficient

When compared to incandescent light bulbs, the estimated energy efficiency of a LED light is up to 80%. This means that only 20% of the electric power is lost, while the other percentage is converted into light. With traditional light bulbs, the ratio is the same, whereas 80% of the electricity is lost.

When you take the long operational lifetime into account, the LED light bulbs become even more efficient, especially in large scale projects.

III. Eco-Friendly

The traditional lighting bulbs contain dangerous chemicals that can hurt the environment significantly. LED lights are free of toxic materials, and they are 100% recyclable. Moreover, the long lifespan means that one bulb can replace 25 incandescent bulbs.

IV. Greater Quality

The materials that make the LED lights are extremely durable, which means that they can withstand even the most adverse weather conditions.

They are perfect for outdoor systems due to the fact that they are shock and impact resistant. With LED lights, you can rest assured that the extreme weather conditions won’t destroy your lighting system.

V. No UV Emissions

LED lights don’t produce UV emissions, which makes them suitable for goods that are sensitive to heat. Moreover, you can illuminate UV sensitive objects such as archaeological sites or even galleries.

VI. Extreme temperatures

Unlike fluorescent lamps, LED lights aren’t influenced by hot or cold outdoor temperatures and their operation isn’t affected in any way. This makes them perfect for areas with winter settings such as freezer rooms.

VII. Frequent Switching

LED lights can be switched on and off multiple times without affecting its lifetime. Moreover, they brighten up instantaneously, which makes them suitable for outdoor projects.

Traditional lighting may take up to few seconds to reach full brightness, and the frequent switching can reduce their lifespan considerably.

VIII. Low-voltage

The LED system doesn’t require a high-voltage power supply, which makes them suitable for remote areas. Moreover, you can connect an external solar-energy source, which will surely power the LED Lighting providing the necessary illumination.

Advantages of Solar Light

Solar power light is energy from the sun that is converted into thermal or electrical energy. Solar power is a kind of inexhaustible and environmentally-friendly new energy resources. The solar street light is one of the applications of solar power.The use of solar power for illuminating streets and other public places is getting popular day by day. It has become a dependable source of lighting streets around the globe. There are multiple benefits of using solar street light fixtures, like conservation of energy, use of a conventional source of energy, and less dependence on the national grid. Tropical countries that receive ample sunlight most time of the year can be highly benefited from this source of light.Solar street lights are water-resistance and weatherproof and have a low glare and low insect attrition rate. The solar panels in these lights convert solar energy into electrical energy that gets stored in the inbuilt battery and is utilized for dusk-to-dawn lighting operations.Solar street light has the advantages of stability, long service life, simple installation, safety, great performance and energy conservation. This kind of light can be widely installed in urban roads, living districts, factories, tourist attractions and parking lots.

System structure:

The solar power light is composed of solar cell module, some LED lamps, control box (the control box is equipped with charger, controller and battery) and lamp pole. The solar panel has a high efficiency of 127Wp/m2, which is very beneficial to the wind resistance design of the system; In the lamp cap part, 1W white LED and 1W yellow LED are integrated on the printed circuit board to form a lattice with a certain spacing as the plane light source. The control box is made of stainless steel, beautiful and durable; The maintenance free lead-acid battery is placed in the control box and the special charging controller for solar street lamps is successfully developed using the patented slow pulse fast charging and discharging technology. The system uses valve regulated sealed lead-acid battery, which is also called “maintenance free battery” because of its little maintenance, which is conducive to reducing system maintenance costs; The design of the charge and discharge controller gives consideration to the complete functions (including light control, time control, overcharge protection, over discharge protection and reverse connection protection) and cost control, so as to achieve a high cost performance ratio.

Operating Principle:

Solar led lights is an electric lamp that is converted into electric energy by solar panel. In the daytime, even on cloudy days, the solar generator (solar panel) can collect and store solar energy. As a safe and environment-friendly new electric lamp, solar led lights has been paid more and more attention. The working principle of solar lamp is simple. The solar cell made by the principle of photovoltaic effect receives solar radiation energy during the day and converts it into electrical energy output. It is stored in the battery through the charge and discharge controller. At night, the illumination gradually decreases to about 101ux, and the open circuit voltage of the solar panel is about 4.5V, The charge and discharge controller acts after detecting this voltage value, and the battery discharges the lamp cap. After the battery is discharged for 8.5h, the charge and discharge control will act and the battery discharge is completed. The main function of the charge and discharge controller is to protect the battery.


The solar led light, which belongs to the technical field of lamps, can be widely used for ornament and decoration on grass, squares, parks and other occasions. The lamp cover is mainly used to connect the bottom bracket. The battery panel is placed on the battery box and embedded in the lamp cover. The battery box is installed on the bottom bracket. The LED is installed on the battery panel. The solar panel uses wires to connect the rechargeable battery and the control circuit. The utility model has the advantages of integrated, simple, compact and reasonable structure; No external power cord, easy to use and install, beautiful appearance; Since the light emitting diode is arranged in the bottom bracket, the whole lamp body is illuminated after emitting light, and the light perception effect is better; All electrical components are built-in and have good practicability. It includes snake lights, plate lights, solar neon lights, massage lights, etc.

In practice, of course, solar outdoor lighting is a little more complex. In addition to large capacity batteries and solar panels, the system also includes advanced special monitors. When the lighting is stopped, the solar power battery starts to charge, and then gets more power when it is recharged. The key is that solar outdoor lighting and solar photovoltaic houses are equipped with solar panels, which have a dedicated microprocessor control system and batteries. It is connected to specially designed load lamps equipped with super reflectivity and high energy ballasts. The utility model has the advantages of high brightness, simple installation, reliable operation, no cable laying, no conventional energy consumption, long service life, etc. It is designed with high brightness LED, without manual operation, and the lamps will automatically light up in the dark and turn off in the morning. The solar led light have a strong sense of fashion, bright texture, fine and modern. They are mainly used for the lighting decoration of green belts in residential areas, industrial parks, tourist scenic spots, parks, courtyards, square green spaces and other places.

The YOULUMI solar street lights are easy to install and easy to transport as well. During the daytime, the solar panels will store the solar energy in the battery. They will absorb the energy and pass it to the battery. During the nighttime, the motion sensor will work to control the light. It will start working automatically.

What Are the Benefits of Solar Street Lights?

The key benefit is the environmentally friendly solution. After installing solar street lights, users can rely on solar energy to power up the streets and other public spaces. As mentioned above, solar street lights are more advanced now. When it comes to the benefits, there are many.

Green Alternative

In traditional lighting, people rely on the grid for energy. During the blackouts, there will be no light. However, sunlight is available everywhere, and it is abundant in many parts of the world. Sunlight is the leading renewable energy in the world. The upfront cost might be a bit more. However, once the installation is done, the expense will be less. In the current condition, solar power is considered the cheapest source of the energy.

As it comes with an in-built battery system, you can power up the streets when sunlight is not available. Also, the batteries are recyclable and will not harm the environment.

Cost-effective Solution

Solar street lights are cost-effective. There is not much difference between the installation of the off-grid solar and grid system. The key difference is that meters will not be installed in solar street lights. Installing a meter will contribute to the end cost. Also, trenching the grid power will increase the installation cost.

Safe Installations

While installing a grid system, some barriers such as underground utilities and the root system might cause interruptions. The electric trenching will be an issue if a lot of obstacles are there. However, you will not experience this problem while using solar street lights. Users just need to set a pole wherever they want to install a solar street light.


Solar street lights are maintenance-free. They use photocells, and that minimizes the maintenance requirements significantly. During the daytime, the controller keeps the fixture off. When the panel does not produce any charge during dark hours, the controller turns on the fixtures. Also, the batteries come with five to seven years of durability. The rainwater will clean the solar panels. The shape of the solar panel makes it maintenance-free as well.

No Energy Bill

With solar street lights, there will be no energy bill. Users will not have to pay the power bill every month. That is going to make a difference. You can use the energy without paying monthly energy bills.


Solar street lights can meet the lighting needs of communities. The high-quality solar street lights will boost the look and feel of the city. The upfront cost might be a bit more.

However, there will be no blackouts and energy bills. As the operating cost will be zero, the community members can spend more hours in the park and public places. They can enjoy their favorite activities under the sky without bothering about the power bill. Also, lighting will minimize criminal activities and create a better and safer environment for people.

Infrared light physiotherapy belt for both people and pets

In order to honor their parents, many children buy infrared physiotherapy belts for their elders during the New Year holidays. Some friends will be worried about the infrared belt will not have side effects, not quite clear about the principle of lumbar belt, and the scope of application, etc. Today, I will explain to you in detail.

What is the principle of red light therapy lamp?

Infrared ray can be roughly divided into three parts, namely, near infrared, wavelength of (3 ~ 2.5) um ~ (1 ~ 0.75) um between; infrared, wavelength of (40 ~ 25) um ~ (3 ~ 2.5) um between; far infrared, wavelength of 1500 um ~ (25 ~ 40) um between.

Among them, the wavelength of 760nm ~ 2000nm near infrared wavelength, is the human body can accept the strongest penetrating ability of the treatment light, its energy can reach the subcutaneous tissue 8 ~ 10cm deep, penetrate the skin, subcutaneous tissue directly to the bones and organs.

The role of infrared physical therapy lamp

Infrared light on the human body, in terms of it and the human body has a very obvious heat-poly effect. Then I explain to you here, because the near-infrared light waves match the human body’s radiation, which can produce a warming effect, and the heat is easily absorbed by the body tissues.

Which can cause vasodilation, accelerated blood flow, improved local blood circulation, and enhanced tissue nutrient metabolism, because it promotes human metabolism, infrared light is also known as the “light of life “In this way, it can accelerate the absorption of local exudates, such as bruises and fluid accumulation, promote the decreasing of swelling, and enhance the self-repair of joints and bone tissues.

Infrared light, from the perspective of human cells, activates tissue cells. When the human body is irradiated by infrared light, it can cut off the long chains of certain connective macromolecular groups (30-40 water molecules) in the body, forming small molecular groups composed of 5-6 water molecules, so that the number and speed of water molecules penetrating into the cell membrane are greatly increased. 

On the one hand, it cleans the cells and strengthens the discharge of toxic substances; on the other hand, it strengthens the exchange of oxygen and nutrients, and other materials and energy, so that the cell membrane and intracellular calcium ion activity is enhanced.

Infrared light can improve microcirculation. Microcirculation refers to the blood circulation in the microvessels between micro-arteries and micro-veins. Its basic function is to realize material exchange between blood and tissue cells, transport nutrients (including nutrients and oxygen) and excrete waste (including carbon dioxide and metabolites), so the microcirculation is the “second heart” of the human body. 

Under normal conditions, the microcirculatory blood flow is compatible with the metabolic level of human tissues and organs, so that the physiological functions of all organs in the body can operate normally. 

When the microcirculation dysfunction or the microcirculation blood volume perfusion is reduced, it cannot meet the needs of tissue oxidation metabolism and causes tissue and organ dysfunction or failure, which is an important reason for the occurrence and development of many diseases.

Combined with the above principles, that is why NIR therapy is widely used in the clinical treatment of inflammatory diseases.

The principle of infrared physiotherapy lumbar belt heating is actually to add massage effect on the basis of infrared light, which can stimulate human acupuncture points, such as for dysmenorrhea patients, can effectively massage the Zhongji point, Guangyuan point, uterus point, these points are important points related to the future of women. 

When these points are massaged through the use of a self-heating magnetic therapy belt, it will have the effect of warming the uterus and the abdomen as well as the stomach, eventually allowing the pain of dysmenorrhea to ease or even disappear, curing the uterine cold and successful conception.

red light therapy for full body

The scope of application of infrared physiotherapy lumbar belt

  1. lumbar muscle strain. The use of the body’s own energy and moisture, continuous release of thermal energy, close to use for about half an hour can feel the obvious heat therapy effect, improve human microcirculation, accelerate metabolism, and quickly eliminate fatigue.
  2.  lumbar disc protrusion, lumbar disease patients. Due to the role of magnetic lines, the formation of magnetic fields around the waist, through the continuous diffusion of magnetic waves and stimulation, the human skin can be micro-kneading, so as to achieve the role of muscle relaxation. The support strip piece not only plays a supporting role, but also plays a certain traction role on the waist.
  3.  suitable for dysmenorrhea, kidney deficiency, spleen and stomach disorders, the body is afraid of cold, postpartum pain, lower abdominal cold, cold pain in the waist, stomach cold stomach pain; long-term wear can burn excess body fat to achieve a certain weight loss effect.

Solar street lights need to be tested for what performance

Solar street lamps will do a lot of tests before the design and production, to test whether their performance meets the national quality requirements and standards, whether it meets the basic specifications and safety standards of solar street lamps, etc., the quality inspection before delivery is more strict and rigorous. Solar street lamps generally need to test the following performance.

1. Photoelectric performance test

The test can effectively detect whether the actual parameters of the solar street lamp have the problem of virtual mark. The luminous efficiency, color temperature, color difference, input and output power, and whether the current and voltage are stable can be detected by the test.

2. Quality of core light source of solar street lamp

The quality of solar street lamp LED light source needs to test the lens process evaluation, packaging glue type, whether there are pollutants, bubbles, air tightness evaluation, chip process evaluation, chip graphics and microstructure measurement, defect search, chip pollutants identification, whether there is leakage, whether there is damage.

 Lead bonding process evaluation, welding morphology observation, arc height measurement, diameter measurement, lead composition identification, etc.

3. Heat dissipation performance of lamps

The integrated solar street lamp is a whole set of batteries, controllers, and LED light sources in one, with good tightness, so heat dissipation should be taken into account when working discharge. As a new type of energy-saving lamp, only 30-40% of the electric energy is converted into light in the lighting process, and the rest is converted into heat energy.

 And the life and quality of the lamp are closely related to the temperature, LED lamp temperature, shell temperature, and heat dissipation temperature will be related to the uniformity of the degree of illumination and quality of life.

Solar street lights need to be tested for performance

4, waterproof and dustproof performance of lamps

Solar street lamps have certain protection level standards, which are generally represented by IP plus numbers. Solar street lamps are usually IP65, IP66, IP67, and must at least reach IP65 waterproof and dustproof level. IP67 level is the highest level of solar street lamps at present.

5. Quality evaluation of solar street lamp power supply

The function of the drive power is to convert the AC mains into a suitable direct current. Reliability, efficiency, power, driving mode, overcharge protection, over-discharge protection, overvoltage protection, temperature negative feedback protection, and other factors should be considered in the selection and design of a driving power supply.

6. Appearance inspection of solar street lamp

Appearance check, size check, material check, assembly check.

7, solar street lamp wind resistance

Solar street lamp is a key factor of the wind resistance of the lamp pole test, because the lamp pole is a certain height, the lamp pole from the material or size ratio should be measured in accordance with the basic data wind resistance coefficient, the general solar street lamp selection is a ten grade typhoon resistance coefficient. 

Especially in the coastal typhoon zone and the northwest area with large windblown sand, the wind-resistant design and wind-resistant ability of solar street lamps must be considered.

8, solar lighting lightning protection design performance

Solar street lighting in summer thunderstorm weather, especially pay attention to lightning protection, solar street lighting products themselves are low voltage, equivalent to its own lightning rod, low pole light is very unlikely to be struck by lightning, but high pole light or to consider and test lightning protection performance.

9. Continuous rain and light duration test

Solar street lamps in use process are the main concern of the rainy day not bright lights or light time is short, to reach the desired ideal effect, so the factory in production of the factory will test before the morning light rainy time length, according to the test data, according to different regions and climate differences, setting and debugging days duration rainy daylight lamp solar street lamps, generally 3 to 5 days, Configure high Settings for 5-7 days.

Solar street lamps after the above performance test leave the factory safely, not only to ensure product quality, and manufacturer reputation, but also to ensure the safety and rights, and interests of consumers, to avoid return and exchange, reduce the cost and expenditure of after-sales service.
