After years of development, led street light technology has been very mature. Many countries have issued various standards to regulate the outdoor lighting product market. There are also many street lighting companies on the market. It is important to choose high-quality and low-cost street lamp products.

The main accessory of led street lamp is light source. The quality of the light source directly determines the quality of the lighting effect. The light efficiency, color rendering index and light attenuation of the light source directly determine the lighting effect and lamp life. High quality chips not only have high lighting effect during installation, but also have a long service life, which is also very expensive. Pursue the price advantage and charge at a low price. The lighting effect looks the same when installed for the first time, but after using for a period of time, the light will be seriously attenuated, thus affecting the lighting effect.

Power supply is also an important accessory of led street lamps. LED light source requires DC constant current input, but our daily current is AC. Therefore, you need a component that converts AC to DC, and the output current must be stable. The value of this component is a constant current source or power supply. Its performance directly affects the service life of the bulb. Under normal use, the life of LED light source can reach 10 years. The LED light can easily damage the power supply. The constant current source will be damaged due to unstable voltage and bad weather (such as thunderstorm, high temperature, heavy rain, etc.).

The main function of the lampshade is to dissipate heat and protect the left and right sides of the LED light source. Good radiators usually use aluminum as the raw material. There are two main treatment methods on the market: aluminum and die cast aluminum. Aluminum is easy to process and has various shapes. Aluminum die castings are complex, small in shape and expensive, but have good heat dissipation effect.
