Comparison between LED and traditional tunnel lighting source LED is a solid-state semiconductor device that can directly convert electricity into light. Compared with the traditional tunnel lighting source (sodium lamp, metal halide lamp, etc.), 100w Street Light Housing manufacturer introduces LED light source Has the following advantages:
(1) Low light decay: If the heat dissipation conditions are excellent, the LED will have positive luminous decay in the first 10,000 hours, 3%-10% in the first 10,000 hours, and basically 30% in the first 50,000 hours, which is far lower than general road lighting sources. The light is more stable.
(2) High color rendering: general LED color rendering is about 70 to 80, if three primary color phosphors are used, it is higher; general high pressure sodium lamp is 20 to 35, 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 ordinary road and tunnel lighting sources, and it is now more than 50000H.
(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 about 2,000 yuan, and its cables and other auxiliary The price of parts is higher than the cost of LED cables.
