LED is a solid-state semiconductor device, which can directly convert electricity into light. Compared with the traditional road tunnel lighting source (sodium lamp, metal halide lamp, etc.), 50w Street Light Housing Wholesaler introduces LED authentic Advantages of the lamp:

(1) Low light decay: If the heat dissipation conditions are excellent, the LED will have positive luminous decay in the first 10000h, the luminous decay of the first 10000h is 3%-10%, and the first 50,000h is basically 30%, which is far lower than the general road lighting source. The light is more stable.

(2) High color rendering: The general LED color rendering is about 70 to 80, and it is higher if three primary color phosphors are used; the general high pressure sodium lamp is 20 to 35, and the low pressure sodium lamp is lower, so even the traditional light source brightness It is higher than LED, but its visual effect is worse than LED. "It is not bright, but it can be seen clearly". This should be a direction for the use of LED light sources.

(3) Lifespan: The lifespan of LEDs is higher than that of general road and tunnel lighting sources, and it is now more than 50,000H.

(4) Price: Although the price of LED lamp holders is higher than that of traditional lighting fixtures, with the sophisticated production skills, their prices are now falling sharply. The price of a set of high and low pressure sodium lamps is generally around 2,000 yuan, and its cables and other auxiliary The price of parts is higher than the cost of LED cables.
