How should we choose LED Solar Studs correctly?

At present, LED Solar Studs is the best choice for energy-saving renovation of road lighting, so how should you choose when purchasing LED Solar Studs? What are the main points of purchase? Ruichen briefly introduces how to choose LED Solar Studs correctly.

1. Luminous efficiency.
Light-emitting diode lighting technology is becoming more and more mature, and high-power light-emitting diodes have been able to meet the lighting requirements of ordinary street lamps. The luminous flux of ordinary high-pressure sodium lamps is 100LM/W, the commonly used high-power LEDs are 50-60LM/W, and the best chip LEDs abroad can reach 80LM/W. The higher the luminous efficiency, the better the energy-saving effect. This is also the choice of LED Solar An important indicator of Studs. However, it is not clearly specified in the standards for LEDs, so it must be carefully checked when purchasing LED Solar Studs.

2. Attenuation of LED Solar Studs.
Nowadays, some merchants use hundreds of 0.5W low-power LEDs in order to reduce the cost and thus the price of LED Solar Studs. However, the attenuation of this low-power LED is very serious, and its attenuation to 80% of its life is only 1000 hours. Therefore, as LED Solar Studs that need to be used for a long time, it is absolutely not allowed to use such low-power LEDs. If high-power LEDs (generally more than 30W) are selected, their light decay will be greatly improved.
3. The self-weight problem of LED Road Studs.
Due to the high technical content and complex components of LED Road Studs, the weight of some high-power lamp caps will greatly exceed that of ordinary high-pressure sodium lamps, so the requirements for corresponding supporting materials are also relatively high. However, some LED Road Studs manufacturers have reduced the dead weight of LED Road Studs as much as possible, from about 30 kg for a single lamp head to more than 10 kg, and the weight has a further downward trend.

4, LED Road Studs heat dissipation.
Since LEDs are semiconductor components, when the wafer is affected by temperature and reduces to 30% of the initial luminous flux, it will lose its lighting meaning, that is, the end of its life. Although the life of high-power LED Road Studs is theoretically as long as 30,000 to 50,000 hours, but The important premise is good heat dissipation. It is worth noting that some domestic LED Road Studs manufacturers have adopted the world's leading needle cooling technology.
