Where is the best place to buy solar street lamps

In view of this problem, we can make a detailed analysis. First, we divide all in one solar street lights into two categories according to the usage scenario:

Category One: Home applications, typically small yard lighting in the home. This kind of place has low brightness requirements, but has certain requirements on the light coverage area and lighting time, and the overall budget is also relatively low.

Second: engineering applications, towns and cities road lighting, or other public lighting, such as parking lots, small squares, ballparks, etc. This scenario has high requirements on brightness and light coverage area. Budgets vary from project to project, but are generally higher than home application budgets.

For home applications, solar street lamps can be purchased from e-commerce platforms or local physical stores.

Household solar street lamps are generally sold by dealers wholesale from manufacturers and put on e-commerce platforms or in their own physical stores. When choosing a seller, be sure to make sure the warranty period and after-sales policies are clear. Try to choose a shop with guaranteed after-sales service, if there is a local entity shop is even better.

The manufacturers of such products are mostly located in Zhongshan, Guangdong Province and Changzhou, Jiangsu Province. There are also manufacturers directly open shop, but less. If you are a distributor and want to wholesale, you need to find a professional manufacturer.

When comparing prices, the following parameters should be consistent or similar to compare prices:

Solar panel power W or size

The capacity of lithium battery AH/ can be multiplied by capacity and voltage into WH contrast

Ignore the bead wattage of the lamp, all are imaginary

Household solar lamp, I recommend the budget in 200-400 yuan, our family for your reference:

Configuration: 25W solar panel, 25AH battery, large Angle lens design, with arm and bracket with expansion screw, independent gift box packaging /> Family happiness positive /> Family side /> Family wrap gift box

If it is engineering lighting, lighting areas such as roads, squares, parking lots and courses, you should find a professional factory directly.

Do engineering street lamp manufacturers, Yangzhou, Jiangsu Province is the most concentrated.

When choosing long-term cooperation manufacturers, we need to find professional manufacturers to cooperate. General engineering not only needs products, but also needs manufacturers to give a set of solutions according to your engineering situation. In the selection process, it is best to visit the manufacturer for field reference.

Professional manufacturers should at least have the following characteristics:

1) Focused factory positioning. A major means to specialize in a certain kind of study or profession. So focus is the prerequisite of professionalism. Only the main energy on the solar street lamp product, it is possible to do this product well. To find out if this factory is focusing on locating solar lamps, check whether the products listed on its website are mainly solar street lamps and whether their production line mainly produces the main components of solar street lamps.

2) Professional technical team. This is also standard for professional factories. Having professional technicians or technical teams means that the factory has gradually risen a level from the pure processing and assembly operations, and began to study what the product is like, what efforts can be made to make it better, and how to avoid the problems encountered in the past. Of course, you also need to check whether his technical staff/team is professional. I think a professional technology should have the following qualities:

  1. a) Clear thinking and systematic presentation of content. Solar street lamp is a new product, there is no very mature system of learning materials, only in-depth study of this product, can be scattered knowledge sorted into knowledge tree.
  2. b) Comprehensive knowledge. Horizontally speaking, because the solar lamp is a system composed of several independent products, professional technology should be very familiar with each major component; Vertically speaking, professional technology must understand the product from raw materials, production, testing, finished performance of every process.
  3. c) With rich experience and profound accumulation, I can identify problems at a glance and apply the right medicine. Given a random question, what might be the possible causes? How should we go about screening? Give the most reasonable solution.
  4. d) Tests and data. Professional research is bound to run countless tests and produce countless data. If the person can’t talk with the data, he hasn’t done actual testing and doesn’t know enough about the performance of the product.
  5. e) Attitude towards work. As the old saying goes, “do what you do, love what you do.” If you don’t love the product and just work by coping, you won’t do well, let alone be professional. Therefore, in the process of communication, it is also possible to feel their attitude towards work to understand their professionalism.

Find out how professional they are by asking a series of questions, such as: Too

How is the formula of solar street lamp configuration derived? It’s a powerful question, and I’m sure few technologies can answer it.

How much can your 100W solar panel charge on rainy days?

What is the charging and discharging efficiency of your controller? How is it tested?

How to solve the problem of lighting in continuous overcast and rainy days? Why do you do this?

What’s the difference between a low pressure system and a high pressure system? Which one is better? Why?

What is the shape of the light produced by your lamp? What is the length and width of the cover at a height of 6 meters?

3) Production of major components. The main components of solar street lamp are solar panel, LED lamp, controller, battery, lamp pole. Of the five components, I think the least technical is the light pole. The other four components are the main components of the solar lamp. Which of them are produced by the manufacturer you investigated? Those who produce more will definitely have an advantage, at least they will know more about these parts and have more control over quality and delivery. The controller is usually outsourced, but this is the brain of the whole solar lamp, and it’s very important that you test the technology in the factory to see if they know enough about the controller.

4) Time accumulation. The manufacturing process is not immune to mistakes, especially when it comes to custom-made, non-standard solar street lamps. Therefore, the experience of their team is very important, and experience means that the mistakes that are easy to make have been made by others, and you are much less likely to make them.

5) Research and development strength. Science and technology is the first power of production, with research and development shows that this factory will have more development potential, may go further

solar street light classification and application areas

Solar street light is divided into two types: DC type and AC type.

The former takes solar panel as the power supply, uses battery to store electric energy, and stores the electric energy in the battery, when there is a load needs lighting, then the battery power supply to the lamps.

The latter takes solar panel as the power supply, and uses solar controller to control the working voltage and power size to control the working status of each component in the whole system.

Scope of application: suitable for lighting and road maintenance in parks, roads and other public places.

At present, the domestic municipal street lights and tunnel lights use more DC type, because these lamps and lanterns do not need electricity, the demand for electrical energy is less.

And in some mountainous areas, islands and other places due to the lack of power supply and power points, will use AC type lamps and lanterns.

The structure of lamps and lanterns

The main structure of solar street light consists of light pole, distribution box, bracket, etc.

Solar Street Light

The choice of light source

Battery as the core component of the solar street light, it is vital to choose the right battery. In order to extend the service life of the solar street light and ensure its good working performance, our battery meets the following conditions.

①Under normal climate, the solar panel generates electricity continuously for at least 4 hours.

②In areas with sufficient sunlight and long duration, the solar panel should have sufficient power generation capacity.

â‘ĒThere is a large enough capacity to store energy (preferably greater than 80%) to ensure that the whole system can be continuously powered.

â‘ĢWhen the light intensity exceeds the rated output power of the solar panel (calculated in watts/m2), the battery should have sufficient storage energy.

Storage Battery selection

The Storage battery capacity is proportional to the charging current. When the output voltage is certain, the higher the charging current, the smaller the battery capacity.

In the solar street light system, the capacity of the battery directly affects the power supply capacity and efficiency of the whole system.

Therefore, we need to install the battery in the solar street light system according to the system needs to design the corresponding battery capacity, select the battery in line with GB/T2099.2-20 08 “low-voltage distribution equipment”, GB/T20042-2004 “test methods for electric motors and generators for lighting fixtures” and GB-T10661-1994 “lighting electrical requirements and test methods – general conditions and test methods” standard requirements of the battery.

How do you charge solar lights without sun?

The need for sunlight cannot be emphasized enough when it comes to solar-powered lights.  All in one Solar street lights need direct sunlight during the day in order to deliver their best at night.  Therefore, it is always recommended to install the street lighting in a shadow-free area so that the panels can absorb maximum sunlight.  How about cloudy and rainy days?  How to charge the lights without sunlight.

solar street light

A cloudy or rainy day certainly affects your solar light’s charging ability and there will be a drop in the duration of illumination during such overcast conditions.  However, clouds do not completely block sunlight and solar panels are capable of absorbing any amount of solar radiation that is available.  This helps the solar lights to continue to light up even during rainy days though at a lower voltage.

If you ask this question to a solar light manufacturer or dealer, most of them will say that solar lights work from dusk to dawn, typically averaging 8 hours. However, there are several factors involved to get your solar lights to stay on long at night.  Solar lights are independent outdoor lighting units that are designed to last and are usually installed to illuminate a commercial or residential area or to decorate a garden to enhance the ambiance.  A solar garden light adds brightness to a walkway or driveway and solar street light suit several other applications.

Solar lights operate with the help of solar energy and will remain shining based on the energy they have stored during the day.  A standard solar-powered lighting unit that receives direct sunlight throughout the day will be fully charged by the end of the day.  Nevertheless, many solar users have complained that their lights have not been working all night long.  How much energy gets stored depends on the type of solar panel and battery used and how long a solar light stays lit depends on numerous factors.  There are a few techniques to follow to maximize the lifespan of a solar lighting system.

Purchasing a quality solar unit from a reputable provider solves half the problem. Choosing the right area for installation is the next step.  It is also important to keep your solar system clean and to check the batteries occasionally and replace if necessary.  It is important to always look into the specifications of your solar light.  Street lighting that are designed to perform all night long switch on automatically at dusk and switch off at dawn, staying on throughout the night.  Again, this depends on how well sunlight is absorbed by the panels and how much energy gets stored in the batteries.

You will know what to expect in terms of lighting hours if you choose the right solar system for your lighting requirements.  There are many varieties of solar lights such as solar street lights, solar garden light, solar outdoor lighting, solar outdoor lighting and more.  Each one has its distinctive specifications and you should purchase your light considering your specific needs.  Usually, solar panels last up to 20-25 years and the batteries have a lifespan of around 4-5 years.  If you think your solar lights are not maintaining charge, routine inspection will help you diagnose the problem and you should know when to replace batteries and panels.

For optimal illumination, it is advisable to install your solar light in a shadow-free area where it receives direct sunlight.  The solar light should also be away from street lighting or other bright house lighting as they can diminish your solar light’s longevity and interfere with the performance of the motion sensors.  Solar lights placed near dusty areas, gardens, play areas or busy roads may require regular cleaning and maintenance.

Tips on how to charge solar lights with indirect sunlight

Keep your solar panels cleaned

Solar lights do not require any frequent maintenance; nevertheless, cleaning the solar panels off dust and dirt will help your lights to charge efficiently.  Solar street lights can absorb sunlight even in cloudy weather.  Any dust accumulation on the panels makes it difficult for the panels to get charged.  Cleaning your solar light with clean water and a microfiber cloth will do the trick.

Position your solar led lights correctly

The solar panels must be placed directly facing the sun as there is less sunlight available during cloudy days.  Occasionally trim shrubs or tree branches blocking the panels and also, avoid installing your solar light next to a bright light source.

  • Redirect sunlight with the help of mirrors

If your solar light is installed underneath a shadow, you can take the help of mirrors to redirect sunlight to your solar panels.  Choose mirrors that are bigger than the panels and place the mirror stand in a diagonal position.  This will help to reflect sunlight and charge the battery.

Use artificial lighting for charging

Place your solar light underneath a household light or close to an incandescent light bulb to charge it.  LED flashlights can also be used to charge your solar led lights.  Do this only if you need your solar lights to light up at night during power outages.  Otherwise, there is no point using a hard-wired light to charge an energy-saving light.

Conclusion

The methods discussed above are not as efficient as direct sunlight; however, they can be a lifesaver.  Of course, the best way to charge your solar powered light is in the presence of direct sunlight; however, the lights can get charged even when there is indirect sunlight.  Most of the solar powered light have energy-saving options now which will help the charge to last for 2-3 days if they are exposed to direct sunlight for 7 to 8 hours during the day.

Youlumi, a leading solar led street light distributor in India, deals with compact solar garden light such as Solar European Pathway Light, Solar Vintage Garden Light and Solar Edison Garden Light.  Since they are small in size, they are easily rechargeable and even though not as quickly and efficiently as during sunny days, they can still charge even in indirect sunlight and put out a decent amount of brightness.

You may temporarily use regular batteries to illuminate your solar LEDs.  However, for the long-term operation of your solar lighting units, take time to purchase the appropriate battery option in order to avoid having to replace your entire solar led street light systems due to the damages caused by regular battery usage.

Learn About LED Lighting

What are LEDs and how do they work?

LED means light emitting diode. LEDs produce up to 90% more efficient light than incandescent bulbs. How do they work? An electric current flows through a chip, illuminating tiny light sources called LEDs to create visible light. To avoid power problems, the heat produced by the LEDs is absorbed by a heat sink.led corn light

Service life of LED lighting products

The lifetime of LED lighting products is defined differently from other light sources, such as incandescent lamps or compact fluorescent lamps (CFLs). LEDs do not burn out or fail. Instead, there is “lumen depreciation,” i.e., a slow reduction in the brightness of the LED over time. Unlike incandescent bulbs, the “lifetime” of LEDs is determined by predicting when the lumen output will decrease by 30%.

How are LEDs Used in Lighting 

LEDs are integrated into lamps and bulbs for general illumination. The small size of LEDs offers unique design possibilities. Some LED lamp solutions can physically resemble lifelong lamps and better match the look of traditional lamps. Some LED luminaires can have LED lights incorporated as a permanent light source. There are also hybrid solutions that use a non-traditional replaceable “bulb” or light source designed specifically for a unique luminaire. LEDs offer many opportunities for innovation in lighting and are suitable for a wider range of applications than traditional lighting technologies.

led corn light

LEDs and Heat

LEDs use heat sinks that absorb the heat generated by the LED and conduct it to the environment. This prevents the LEDs from overheating and burning out. The higher the operating temperature of the LED, the faster the light decays and the shorter its lifetime.

LED products use many unique designs and configurations of heat sinks to control heat. Advances in materials now enable manufacturers to develop LED lamps that match the shape and size of traditional incandescent bulbs. Regardless of heat sink design, all Youlumi compliant LED products are tested for proper thermal conductivity to maintain light output throughout the lamp’s rated life.

How does LED lighting differ from other light sources such as incandescent lamps and compact fluorescent lamps (CFLs)?

LED lighting differs from incandescent and fluorescent tubes in several ways. Carefully designed LED lighting is more efficient, more versatile and lasts longer.

LEDs are “directional” light sources, meaning they emit light in one specific direction, unlike incandescent and compact fluorescent lamps, which emit light work and heat in all directions. This means that LEDs can use light and energy more efficiently in many applications. However, it also means that sophisticated technology is required to produce an LED light bulb that emits light in all directions.

LED Corn light

The most common LED colours are yellow, red, green and blue. To produce white light, LEDs of different colours are combined or coated with phosphor, which turns the colour of the light into the familiar ‘white’ light work of everyday life. Phosphor is a yellowish material that coats some LEDs. Coloured LEDs are widely used as lights and indicators, for example in computer power buttons.

How does light work?

In an energy saving lamp, an electric current flows between the electrodes at the ends of the gas tube. This reaction produces ultraviolet (UV) light and heat. The UV rechargeable work light is converted into visible light works when it hits the phosphor layer of the lamp. Find out more about energy saving lamps.

Incandescent lamps use electricity to heat a metal filament, known as an incandescent lamp, which produces work light led until it becomes ‘white’ hot. As a result, 90% of the bulb’s energy is released as heat.

Why choose Youlumi’s certified LED lighting products?

There are more lighting options than ever before. Yet Youlumi continues to be an easy choice to save on your electricity bills.

Youlumi brand LED bulbs have special requirements designed to replicate the familiar feel of standard incandescent bulbs so they can be used in a wide range of applications. As shown in the chart to the right, a generic LED bulb that is not Youlumi certified may not diffuse light works everywhere and may disappoint when used in a table lamp.

Factors to be Considered Before Buying LED Lights Online

Design: LED lighting is a versatile design element due to its small size, allowing manufacturers and designers to develop technologies, designs and shapes that were not previously possible.

Lumens, not watts: people have traditionally used watts to measure the brightness of a work light stand since the invention of the incandescent rechargeable work light.How does light work? Watts measure the energy consumption of a lamp, not its brightness. When buying LED lights, you need to check the number of lumens, which is the true measure of brightness. Before you buy a rechargeable work light, choose the appropriate lumen and brightness.

Color Temperature: The choice of color temperature is a very personal issue as it affects how a person perceives the environment. In simple terms, color temperature indicates the appearance of the work light led emitted by the lamp.

Efficacy: The technical term for the efficiency of a light works source, which is how much work light led is produced per unit of electricity, is efficacy. You can save the most money if you choose a lamp with high efficiency. However, some people find this concept confusing. The European Union has introduced energy labels for lamps ranging from E to A++, which are loosely based on efficiency, to help consumers.

Dimming: The dimming function creates a relaxing atmosphere in your home or business. In addition, dimming prolongs the life of the lamp and reduces energy consumption.

Lifetime: if you regularly use LED luminaires, lifetime is another important consideration. If you use LED luminaires regularly, it is important that the LED luminaire lasts a long time. If you choose a device with a warranty, you have the option to replace the device even if it breaks down during the warranty period.

Cost: Last but not least factor is LED light’s price. The initial cost of work light stand is high, but they last longer in the long run. The initial cost of work light led is expensive but the long term life is longer. Think about this in relation to your needs.

How to Choose a Safe Beauty Device for Red Light Therapy at Home

Is LED red light therapy safe? What are some of the important factors to consider when choosing a beauty device for red light therapy at home?

Red Light Frequency

There are two main factors that maximize the benefits of red light therapy; the intensity of light energy and the red light frequency. With advanced technology, some beauty devices deliver red light ranging 800-900nm, but most devices deliver red light between 630-700nm and can absorb into the skin to a maximum depth of between 4 and 5 nm. You would want a red light device that provides the most effective light wavelength, which is usually around 660nm red wavelength and 850nm near-infrared wavelength.

Irradiance of device

If you don’t factor in the irradiance of your red LED light device, then you could end up with a low-power red light that doesn’t have any healing effect on your skin. Irradiance is the power density of red light over a given area. It is the amount of light energy output from when the device connects with its target.  If irradiance is too low, the device will not be as effective in cellular penetration.

Treatment Area

One common problem with customers is that they buy an LED red light device to treat a certain area but later realize it cannot help with other parts. Some anti aging skin care products and devices are made specifically for some benefits, while others might be multi-purpose for several treatments. That’s why you need to carefully read the description of the product to learn about its intended use before buying.

Product Quality

If you are looking to take your skincare rituals seriously, then you want to get the best of the best in the market. Ensure that you get quality FDA cleared device products by looking at the certificates and standards from board certified dermatologist that confirm that the device is authentic and safe for use.

Seller Reputation

It is important for customers to get red LED lights devices from trusted sellers as some beauty devices sold may not be a genuine version of reputable brands. Buying from reputable brands will give you the assurance that the products are authentic and safe for use.

User Reviews and Feedback

It is also important to read the reviews and feedback sent by customers after using the product. Go to the device online site and see what customers are saying about the devices and if they are getting the expected results. Both positive and negative testimonials given by customers will help you make the right decision when buying an LED light therapy device.

How Does Red Light Therapy Work?

These specific wavelengths of red light create a biochemical affect in our cells that serves to increase mitochondrial function. This improves ATP (adenosine triphosphate) production in the body.

Why is this important?

ATP is the source of energy for every cell in the body. Without it, we don’t function at all. Without enough of it, we don’t function well.

It’s wavelengths range between 660-850nm and are used to treat the skin’s surface. Red therapy light penetrates about 8-10 millimeters into the skin. Depending on which area of the body the red light is used, this can easily affect all skin layers, reaching into blood vessels, lymph pathways, nerves, and hair follicles.

The History of Red Therapy Light Use

Red light therapy has been around the block. In 1903 physician Niels Ryberg Finsen won the Nobel Prize in Medicine for his successful treatment of smallpox and lupus with red light. Russia uses low level laser therapy in their standard medical care (and they have since the 1970s). The Russians also published hundreds of studies over the decades on the benefits of red therapy light. Unfortunately, very few of these studies have been translated into English.

Red light therapy has largely been ignored by the US and western Europe until recently. However it’s been used in a clinical setting since the 1980s in Japan, China, Canada, Northern Ireland, Vietnam, Latin America, and Eastern Europe.

The Benefits of Red Therapy Light

Even though the western world is behind the times with red therapy light, strong evidence supports its health benefits. It is FDA approved for chronic joint pain, slow to heal wounds, wrinkles, hair loss and acne. Many others have used it successfully for other issues, like psoriasis, improved circulation and better immune function.

Here’s a partial list of the evidence-based uses of red therapy light:

  • It helps rejuvenate facial skin and smooths skin tone.
  • Red light builds collagen in the skin to reduce wrinkles.
  • It helps to repair sun damage.
  • Red light activates the lymphatic system for potentially improved detoxification.
  • Decreases inflammation in the skin.
  • Helps fade scars and stretch marks.
  • Improves hair growth to reverse balding.
  • Stimulates slow healing wounds.
  • Can prevent recurring cold sores, or herpes simplex.
  • Helpful in the short term for carpal tunnel syndrome.
  • Beneficial for skin to reduce eczema, rosacea, and acne.
