Reasons why solar street lights replace traditional street lights

We all know that road lighting is an important part of urban lighting. In the past, we used traditional street lights, and now traditional street lights are slowly being phased out, and solar street lights have become a popular product. What are the advantages of solar LED street lights over traditional street lights? Why can it gradually replace traditional street lights? The following editor of Century Sunshine Lighting will tell you:

1. More energy saving and environmental protection

In the past, ordinary street lamps contained some harmful substances and harmful rays in the spectrum. LED street lights have no mercury, no ultraviolet rays, and no radiation, which is more conducive to environmental protection and human eye health. Compared with ordinary street lights, LED street lights are indeed an energy-saving and environmentally friendly lighting product, which is more in line with our needs.

2. Low input cost

Traditional street lamps in the laying project are much more complicated than LED street lamps. Not only digging holes, but also leading the way, the manpower and material resources are very expensive, and the electricity bill of traditional street lamps is high, and the cost is relatively high.

LED street lights not only do not need to dig holes or even cables, but also need to intercept 1/3 of ordinary street lights, saving a lot of manpower and material costs. “Compared with traditional street lights, LED street lights are a more energy-efficient and environmentally friendly product. The cost of LED street lights is much lower than ordinary street lights.

In addition, the maintenance cost of LED street lamps is also extremely low, and the full investment cost can be recovered in less than 6 years.

3. Lighting brightness

Compared with traditional street lights, LED street lights have stronger lighting functions. A 60W LED street lamp can reach the brightness of a 250W high-pressure sodium lamp, which not only saves a lot of electricity, but also greatly improves the brightness. The light color of LED street lights is uniform, it does not add lenses, and does not sacrifice uniform light color to improve brightness, which is a very good product.

4. Reliable quality

I believe many people will care about the quality of LED street lights, now let’s talk about its quality. In fact, for LED street lights, you can rest assured, because its circuit power supply uses high-quality components, and each LED has its own over-current protection, so there is no need to worry about damage. More importantly, it is waterproof and shock-resistant, and its quality is absolutely safe and reliable.

Generally speaking, LED street light is a good product that is very environmentally friendly and energy-saving. Due to its many advantages, it has gradually entered people’s field of vision and has become the best energy-saving light source in the world, replacing traditional street lights. It is also the best choice for road lighting! If you need to buy LED street lights, we must choose regular street light manufacturers to ensure product quality and follow-up speed!

5. High safety factor

In the past, we also mentioned that ordinary street lamps, that is, high-pressure sodium lamps, contain harmful substances and harmful rays in the spectrum, which will pollute the environment and cause slight damage to the human body. “Not only that, the installation of ordinary street lights is complicated, and accidents such as fire and electric shock may also occur during use. LED street lights will be more reassuring, and safety risks can be greatly reduced in installation and use.

Six, long service life

We all know that whether the lifespan of this street lamp is long or not actually has a great impact. If the lifespan is not long, it means that it needs to be replaced frequently. Frequent replacement is not only costly, but also causes a lot of inconvenience. Especially when changing, it will affect the traffic, and there are many troubles in reinstalling.

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.
