Replaced by the super bright LED, incandescent lamps used in traffic lights, warning lights, marker lamps all over the world, compared with incandescent lamps, LED traffic lights, low power consumption, long life, and The magnitude of increase brightness, to become the ideal light source for traffic lights.
1, showing that good:
LED Flood light 10W traffic lights under continuous light, rain, dust and other adverse weather conditions, can still maintain good visibility and performance indicators. The LED light is monochromatic, and therefore do not need to use color film to produce red, yellow and green signal colors; the LED light is directional, and the divergence angle, it can be to abandon the non-traditional semaphores spherical reflective mirror. The LED characteristics to solve the traditional signal light the existence of the phantom (commonly known as false display) bleaching and color film, to improve the luminous efficiency.
led power 50w light source is very obvious advantages in energy saving, its significant features one of the low energy consumption lighting application makes sense. LED traffic lights is almost 100% LED excitation energy into visible light, contrast, incandescent bulbs, 80% of heat loss, and only 20% become visible.
3, low heat:
The LED Light is directly replaced by the electrical energy light source, the heat generated is very low, almost no heat. LED traffic lights cooling the surface to avoid burns of the maintenance staff, and can get a longer life.
4, long life:
The lights work environment is relatively harsh, bitter cold and scorching heat, sun and rain, and thus require a higher reliability of the lamp. The average life expectancy of the general lights with incandescent bulbs is 1000h, the average life expectancy for low-voltage halogen bulb is 2000h, and the resulting high maintenance costs. LED traffic lights filament shocks cause damage, no glass rupture problem.
5, the reaction:
Halogen bulb, led driver 120w traffic lights is less than the fast response time, thereby reducing the cross accidents.
The important role of 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, the high profits but also conducive to the development of LED production and design company for the LED Spotlight 30W industry as a whole will produce a positive stimulus.
