Chinese Led Street Light Manufacturers

LED Street Lights

Road lighting is closely related to people’s life. LED has low energy consumption and high luminous efficiency as a new light source. This series of advantages have attracted people’s attention and has been applied to street lamps. The difference between led street lights and traditional street lights is that they have low-voltage DC. The outdoor led street lights have unique advantages. Such as high efficiency, safety, energy saving, environmental protection, and long life.

LEDs are gradually becoming known to the public. More and more LED light streets are used as decoration in significant cities. The well-designed street lights LED by ADNLIFE are precise, controllable, and elegant. As a Chinese led street light manufacturer, we can offer a broader range of LED outdoor street light options.

LED Street Light Components/Parts

LED street light accessories include LED chips, PCB boards, lenses, power supplies, housings, lightning protection devices (optional), and control components (optional). The picture above is the street lights led circuit diagram.

LED Chips & PCB Board

LED chips mainly include COB and SMD. The most commonly used street lamp models in street lamps are SMD3030 and SMD5050. The leading brands of LED chips are Philips, Bridgelux, Samsung, CREE, Sanan (second line), and more.

Since the input voltage (3V/6V) and current of a single LED chip are very small, it must be soldered to the PCB board. It is needed for the series and parallel connection to be connected to the power supply. The PCB board can also play the role of cooling the LED. The material of led street lamp PCB is generally aluminum.

Power Supply

Solar panels are responsible for converting solar energy into electricity. The solar panel cells of solar lamps can be divided into monocrystalline silicon and polycrystalline silicon. The most recommended way to extend the working time of street lighting led is to increase the power of solar panels. We insist on using Grade A Monocrystalline solar panels!

LED Street Light Shield – Aluminium House

The led outdoor street lights shell effectively protects the LED chip, power supply, wires, and other components from erosion caused by an external force. The exterior design of the street light housing can also decorate the surrounding environment.

Since about 2008, hundreds of led street lamp housings have appeared. Initially, the LED chip has low light efficiency and generates much heat per wattage. Therefore, the led street lamp housing needs a large heat dissipation area and should be large and heavy.

With the continuous improvement of LED light efficiency, the heat emitted by a single wattage gradually decreases. Correspondingly, the housing of the street lamp becomes smaller and lighter in weight.

LED Lens

Outdoor led street lights are composed of various LED lenses. Each has its distinct features and beam angle. Below are the types you can choose from

Road Type

Depending on the road, lenses with different light divisions can be used. In this way, the uniformity of road lighting can be maximized. The uniformity of road lighting should be above 0.4. Below are pictures of several common road types.

Light Distribution Curve

In the light distribution diagram, the light distribution curve of the street light is very similar to the wings of a bat. The lateral light-emitting angle of the street light road lens is between 130° and 150°. The longitudinal beam angle is between 60° and 70°. Below are pictures of several street light distribution curves.
