Comparison of the functions of conventional tunnel lights and LED tunnel lights and how to choose:
At present, high-pressure sodium lamps are mostly used as light sources for tunnel lighting, but high-pressure sodium lamps have many shortcomings in radiation form, color rendering, visual sensitivity, power specifications, and brightness control. , especially the controllability of brightness, overcomes many shortcomings of high-pressure sodium lamps, and is becoming the mainstream lamps for tunnel lighting in the world today. The state has also introduced new measures for the "ten cities, ten thousand lights" semiconductor lighting project, which has brought unprecedented opportunities for the development of LED tunnel lights.


LED is a light-emitting diode, which is a semiconductor light-emitting technology. The earliest developed LEDs can only emit red light and are used for indicator lights in electronic equipment. With the development of technology, LED lamps can now emit various colors of light and are widely used in various industries. The main application markets include traditional display and signal light markets, backlight markets, street lights, tunnel lights, and automotive lighting markets. , Outdoor landscape lighting and interior decoration lighting market, special lighting market. LED has its unique advantages as a tunnel light source.

(1) LED tunnel lights have low power consumption and energy saving. Compared with traditional high pressure sodium lamps, their energy consumption can be saved by more than 40%.
(2) The LED tunnel lamp has a long lifespan, 100,000 hours in an ideal state, while the lifespan of high-pressure sodium lamps and fluorescent tubes is only 10,000 to 30,000 hours.

(3) LED tunnel lights have high reliability, low maintenance and maintenance costs, and the mean time between failures (MTBF) is as high as 20,000 hours, while the mean time between failures (MTBF) of high-pressure sodium lamps and fluorescent tubes is less than 10,000 hours. h.

(4) The construction cost of the power distribution system (cables, transformers, distribution boxes, bridges, etc.) is reduced. In the case of long tunnels and long-distance power supply, cables and power distribution facilities account for a particularly large proportion of the cost. LED tunnels are used. Lamps can greatly reduce the investment in cables and power distribution equipment due to energy saving.
(5) LED tunnel light can be started instantly, which is convenient for brightness adjustment. It has the advantages of no stroboscopic and wide starting voltage range. It can realize various energy-saving methods, such as intelligent adjustment of illumination according to the traffic flow of roads and tunnels.
(6) High-pressure sodium lamps, fluorescent lamps, and electrodeless lamps contain chemical pollutants such as mercury and lead, while the LED tunnel light source does not contain chemical pollutants and is a green and environmentally friendly light source.
