LED what are the tunnel lights?
(1) a small decline: if the radiation condition is good, before LED 10000h is light, before the 10000h decay was 3% 10%, 50000h is 30%, far lower than the ordinary road lighting light source, lighting more stable.(2) high color: General LED color is about 70 ~ 80, if you use three color phosphor more high; general high pressure sodium lamp is 20 ~ 35, the low pressure sodium lamp is lower, so even if the traditional light source brightness is higher than that of LED, but the visual effect is worse than LED, "not the brightest, but see the most clearly" this should be a direction of development of the application of LED light source.(3) life: the life expectancy of LED is higher than that of general tunnel lighting. Now it is generally higher than 50000H.(4) price: LED lamp although prices than traditional lighting, but with the maturity of the manufacturing technology, the price is now in continuous decline, high low pressure sodium lamp generally set the price at 2000 yuan, while the price is higher than the cable accessories LED cable and other expenses.
The utility model has the advantages of high reflection efficiency, good light transmission performance, energy saving and environmental protection.Compared with the traditional LED LED tunnel lighting is a solid state semiconductor devices, which can be directly converted into electricity to light, road tunnel lighting (compared with the traditional sodium lamp, metal halide lamp), LED light source has the following advantages:
LED tunnel light is one.LED tunnel lamp is a light efficiency energy-saving lamp, using a light emitting diode (LED) as the light source, high luminous efficiency, long life, with a different mirror to achieve multi-purpose lighting; and after softening treatment, will make people dizzy or other discomfort. The ballast adopts overheat protection technology to ensure the service life of the lamp. Imported high purity mirror anodized aluminum material is used as reflector, and the power factor is greater than 0.9 through precise light distribution design,
Buy LED tunnel lamp, whether the lumen volume first note LED tunnel lamp is higher than 100, light must be less than 3%, the temperature must be less than 60 degrees, the power factor is above 90, recommend that you purchase a LED tunnel lighting lamp, LED tunnel lamp warranty of up to three years, high light rate of patent LED the chip, to ensure high light efficiency, low light decay, can reach 6/1000. The shell adopts high thermal conductivity aluminum material to ensure the long service life of the lamp. Now, there are 300 roads in our country which use the LED tunnel lamp of Yan Sen lamps!
