1. First look at the solar panel intuitively. The larger the size of the solar panel and the greater the power, the higher the charging efficiency. 2. Look at the connection line b Read More
1. Heat conduction plate heat dissipation: it is to dissipate the heat generated by the solar led street lamp to a conductor, and the heat is exported out of the lamp cap through t Read More
5. Surge protection: The ability of LEDs to resist surges is relatively poor, especially the ability to resist reverse voltage. It is also important to strengthen protection in thi Read More
If the solar street light has poor heat dissipation, it will accelerate the life of the LED lamp, and affect the lighting effect. Long-term poor heat dissipation will increase the Read More
1. LED lights cannot directly use the conventional mains grid voltage. Due to the characteristics of the LED light source, in order to meet the special voltage and current requirem Read More
1. High reliability: It is especially like the driving power supply of LED street lights, which is difficult to maintain and costly when installed at high altitude. 2. High efficie Read More
Advantages: no danger of exhaustion; safe and reliable, no noise, no pollution emissions, absolutely clean; not restricted by the geographical distribution of resources, can use th Read More
The luminous intensity of any luminaire is different in all directions in space. We can use data or graphs to record the distribution of luminous intensity of the luminaire in spac Read More
2021 Ningbo International Lighting Exhibition is being held at Ningbo International Convention and Exhibition Center. This exhibition provides professionals in the lighting industr Read More
Generally, the light source cannot be infinite, and the light emitted by the light source or the lamp is divergent (except for the parallel light-emitting spotlight), and the light Read More
There are generally three ways to express the light distribution curve: one is the polar coordinate method, the other is the rectangular coordinate method, and the third is the equ Read More
