Led tunnel light is a kind of light-efficiency energy-saving lamps. Light-emitting diodes (LED) are used as the light source of the luminous body. It has high light efficiency and long life. It can be used with different reflectors to achieve multi-purpose lighting; and after softening treatment, it will not cause people Dazzling or other uncomfortable reactions. The ballast uses overheating protection technology to ensure the service life of the lamp. Imported high-purity mirror-surface aluminum anodized material is used as the reflector and is designed with precise light distribution. The power factor is greater than 0.9.
High reflective efficiency, good light transmission, energy saving and environmental protection.
Comparison of LED and traditional tunnel lighting source LED is a solid-state semiconductor device that can directly convert electricity into light. Compared with traditional road tunnel lighting sources (sodium lamps, metal halide lamps, etc.), LED light sources have the following advantages:
(1) Low light decay: If the heat dissipation conditions are good, the LED will have positive luminous decay in the first 10,000 hours, 3%-10% in the first 10,000 hours, and 30% in the first 50,000 hours, which is much lower than ordinary road lighting sources. Luminescence is more stable.
(2) High color rendering: general LED color rendering is about 70 to 80, and it is higher if three primary color phosphors are used; general high pressure sodium lamp is 20 to 35, low pressure sodium lamp is lower, so even the traditional light source brightness Higher than LED, but the visual effect is worse than LED, "not the brightest, but the clearest to see" This should be a direction for the development of LED light source applications.
(3) Lifespan: The lifespan of LEDs is higher than that of general road tunnel lighting sources, and is now generally higher than 50000H.
(4) Price: Although the current price of LED lamp holders is higher than that of traditional lighting fixtures, with the maturity of manufacturing technology, their prices are currently 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.
