Four advantages of LED tunnel lights
Comparison between 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: 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 Higher than LED, but the visual effect is worse than LED, "not bright, but see clearly" 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.
How to install LED tunnel lights
LED tunnel lights have various installation methods such as ceiling type, boom type, seat type, wall type, etc., making the operation more convenient. Adapt to the needs of different work site lighting. The integrated design of the lamp and the electrical box has strong overall reliability, low failure rate, and safer and more convenient maintenance. LED tunnel lights can use intelligent control technology to realize their own dimming control and save energy. Basic situation of LED tunnel lighting. Long tunnels are equipped with lamps according to the double-hole one-way driving mode. The tunnel lighting is divided into entrance section, transition section 1, 2, 3, basic section and exit section; the lighting functions are divided into three types: enhanced light, day light and emergency light . Lamps are arranged on both sides, and the installation height of the lamps is 5.5 meters.
