Analysis of traffic lights with LED several advantages
Replaced by a super-bright LED incandescent used in LED Traffic Light warning lights, marker lamps worldwide, compared to incandescent lamps, LED traffic lights advantages of low power consumption, long service life, and can greatly increase the brightness, the ideal light source for traffic lights.
1, good visibility:
LED traffic lights in continuous light, rain, dust, and other harsh weather conditions, to maintain good visibility and performance indicators. The light emitted by the LED is monochromatic light, and thus do not need to use the color film to produce red, yellow, and green signal color; LED issued light having a directivity, and have a certain divergence angle, thereby can abandon using the traditional semaphore non-spherical mirror. LED's characteristics to solve the traditional signal lights phantom (commonly known as false) bleaching and color film, to improve the optical efficiency.
2, power saving:
LED light source in the energy-saving aspects of the advantage is very obvious, one of the significant features is the low energy consumption, this is of great significance for lighting applications. Almost 100% LED LED traffic lights became visible light excitation energy compared to incandescent bulbs with 80% heat loss, and only 20% become visible.
3, low-grade fever can:
LED is directly replaced by the electric energy light source, the heat generated is very low, almost no fever. The surface can be cooled by the LED traffic signal to avoid burns of the maintenance personnel, and a longer life can be obtained.
4, long life:
Lights work environment is relatively harsh, cold summer, sun and rain, and thus high reliability requirements for lighting. The average life expectancy of the general lights with incandescent bulbs 1000h, the average life expectancy is low voltage halogen bulb 2000h, resulting high maintenance costs. LED traffic lights, no filament shocks cause damage, no glass breakage problem.
5 quick response:
LED traffic lights, halogen bulb, beyond the fast response time, thereby reducing the cross accidents.
Due to the important role of the traffic lights in urban traffic, every year, a large number of traffic lights need to be updated, and thus leads to a relatively large market, after all, high-profit but also conducive to the development of LED production and design company} for the entire LED industry also have a positive stimulus.
