The difference between an LED and a traditional light source

The difference between led traffic lights and traditional light source traffic lights:

Service life:

Led traffic light, long operation life, usually can reach 10 years, considering the influence of bad environment, wild life expectancy to cut to 5 ~ 6 years, not need repair.

Traditional traffic lights, such as incandescent and halogen lamp life is short, have trouble replacing light bulbs, demand to replace three to four times a year, repair and maintenance cost is higher.

Planning:

The led traffic signals are significantly different from those of traditional light lamps in the planning of optical systems, electrical parts, cooling methods and structures. Because it is made up of multiple LED lights picture light planning, so the LED traffic lights can be adjusted through planning of leds, let their own constitute a variety of picture. And be able to make all sorts of color into a body, the various signal into an organic whole, make the same lamp body space can give more traffic information, equipment more traffic planning, can through the pictures of different parts of the LED switch dynamic picture signals, thus make it more humanized and traffic signal, more vivid.

Traditional light source traffic signal lamp is mainly composed of the optical system consists of light source, lamp holder, reflector, and light cover, in some respects is still has some deficiency, don't like the led traffic light, for the led planning adjustment, make its own constitute a variety of picture. These are hard to achieve with conventional light sources.
