The main accessory of LED street lamp is the light source, which directly determines the lighting effect of the lamp. The light effect, color rendering index and light decay of light source directly determine the lighting effect and lamp life. High-quality chips not only provide better lighting when installed, but also last longer, and of course cost more. If you only pursue the price advantage, the lighting effect will look similar at the initial stage of installation, but after a period of use, the lighting effect will be seriously degraded, affecting the lighting effect.

Power supply is also an important accessory in LED street lamps. The led light source needs a constant current input, and our daily current is alternating current, so we need a component to convert alternating current into DC, and the output current needs to maintain a stable value. This element is the constant current source, which is the power supply. Its performance directly determines the life of the lamp. Under normal use, the life of led light source can reach 10 years. The power supply in LED street lamps is easily damaged. Unstable voltage, thunderstorms, high temperatures, heavy rain and other severe weather can damage the constant current source.

The main function of LED street lamp shell is to dissipate heat and protect the left and right sides of led light source. Good radiators are generally made of aluminum. There are two kinds of radiators on the market: aluminum profiles and die-cast aluminum. Aluminum profiles are easy to process and have many shapes. Die-casting aluminum process is relatively complex, less shape, higher cost but better heat dissipation effect.

Make sure you keep your eyes open and choose the right product for you.
