The light source of traffic signal lights is now mainly divided into two categories, one is LED light source, the other is traditional light source, namely incandescent lamp, low-voltage halogen tungsten lamp, etc., and with the increasingly prominent advantages of LED light source, it is gradually replacing the traditional light source. Are LED traffic lights the same as traditional light lights, can they be replaced with each other, and what are the differences between the two lights?
1. Service life
LED traffic lights have a long working life, generally up to 10 years, taking into account the impact of the harsh outdoor environment, the expected life is reduced to 5~6 years, no maintenance is required. The service life of traditional light source signal lamp, if incandescent lamp and halogen lamp is shorter, there is the trouble of changing bulb, need to change 3-4 times every year, maintenance and maintenance cost is higher.
2. Design
LED traffic lights are obviously different from traditional light lamps in optical system design, electrical accessories, heat dissipation measures and structure design. Because it is composed of a plurality of LED luminous body pattern lamp design, so can adjust the LED layout, let itself form a variety of patterns. And can make all sorts of color a body, the various signal into an organic whole, make the same lamp body space can give more traffic information, configuration more traffic plan, can also through the design of the different parts of the LED switch into a dynamic pattern of signals, so that the mechanical traffic signals become more humane, more vivid.
In addition, the traditional light signal lamp is mainly composed of optical system by light source, lamp holder, reflector and transmittance cover, there are still some deficiencies in some aspects, can not like LED signal lamp, LED layout adjustment, let itself form a variety of patterns, these are difficult to achieve by the traditional light source.
