What are the advantages and development prospects of LED tunnel lights?
LED tunnel light is a kind of light-efficiency energy-saving lamps. Light-emitting diodes (LEDs) are selected as the light source of the luminous body, with high light efficiency and long life. It can realize multi-purpose lighting with different reflectors; Dizziness or other uncomfortable reactions. The ballast adopts overheating protection technology to ensure the service life of lamps.
Service life: The service life of LED tunnel lights is higher than that of general road tunnel lighting sources, and is now generally higher than 50000H.
Comparison of LED and traditional tunnel lighting sources LED is a solid-state semiconductor device, which can directly convert electricity into light. Compared with traditional road tunnel lighting sources (sodium lamps, metal halide lamps, etc.), LED tunnel lights have the following advantages:
Low light decay: if the heat dissipation conditions are good, the LED tunnel light has positive light decay for the first 10,000 hours, 3% to 10% for the first 10,000 hours, and 30% for the first 50,000 hours, which is far lower than that of ordinary road lighting sources. more stable.
High color rendering: Generally, the color rendering of LED tunnel lamps is about 70-80, and it is higher if three-primary phosphors are used; the general high-pressure sodium lamp is 20-35, and the low-pressure sodium lamp is lower, so even if the brightness of the traditional light source is high It is better than LED, but the visual effect is worse than LED tunnel light.
Low long-term cost: Although the current price of LED tunnel lights is higher than that of traditional lighting fixtures, its maintenance cost is low, thanks to its long service life, while traditional lighting fixtures have to be replaced regularly, which requires investment not only in products but also in manpower. More, so in the long run, LED tunnel lights can save more costs.
Now with the rapid development of road traffic construction in my country, the construction scale and number of road tunnels are also increasing. With the increasingly mature LED light source technology, the domestic lighting industry has also carried out research and application practice of LED application in road tunnel lighting. Therefore, combining advanced control methods in tunnel lighting, the use of LED tunnel lights with high light efficiency, good stability and long life will become a demand and trend.
