LED Tunnel lamp is a light efficiency energy-saving lamps, the selection of Light-emitting diode (LED) as a light-emitting light source, high luminous efficiency, long life, with different mirrors can achieve multi-purpose lighting; The ballast chooses the overheat protection technology, guarantees the lamp service life. Imports of high purity mirror aluminum anode oxide material to do the reflector and through the precise distribution design, the power factor is greater than 0.9,
High reflective efficiency, good light transmittance, energy saving and environmental protection.
Led and the traditional tunnel illumination light source contrast LED is a solid-state semiconductor device, it can directly convert electricity into light, compared to traditional road tunnel lighting source (sodium, metal halide lamp, etc.), LED light source has the following advantages:
(1) Light attenuation small: if the heat dissipation conditions are good, the LED 10000h is positive light decay, the former 10000h optical decay is 3 110, the former 50000h basic is 30%, far below the ordinary road lighting source, luminous more stable.
(2) High color rendering: General LED color is about 7 10 0, if the use of three phosphor phosphors higher; general high-pressure sodium lamp for 2 35, low pressure sodium lamp, so even though the traditional light source brightness is higher than led, but the visual effect is worse than the LED, "not the brightest, but see the clearest" this should be LED light source application development direction.
(3) Life expectancy: Led life expectancy is higher than the general road tunnel lighting Source, is now generally higher than 50000H.
(4) Price: Although the price of LED lamp is higher than the traditional lighting, but with the maturity of manufacturing technology, the price is now in a large decline in the constant, high and low pressure sodium lamps in general a price of about 2000 yuan, and its cable and other ancillary parts price higher than led cable and other costs.
In addition, LED also has a high maintenance coefficient, good safety performance, no stroboscopic and energy-saving environmental protection advantages.
