The competent authorities of each country of the traffic signal light must formulate corresponding specifications, specifying the color of the signal, the lowest lighting intensity, the patterns of the beam space distribution, and the requirements for the installation environment. Although these requirements are written according to incandescent lamps, the ultra -high brightness LED traffic signal lights are basically applicable. Compared with incandescent lamps, LED traffic signal lights have a long working life and can generally reach 10 years. Considering the impact of the harsh outdoor environment, the expected life span will be reduced to 5-6 years. Ultra -high brightness ALGAINP red, orange, and yellow LED has been industrialized, and the price is cheaper. If a module composed of red ultra -high brightness LED replaces the traditional red incandescent transportation signal light head, it can cause the red incandescent lamp to cause security The impact is low to minimum. Generally, the LED traffic signal module consists of a series of LED single lights connected by several groups. Taking a 12 -inch red LED traffic signal module as an example, the LED single light connected in 3-9 groups, each series of LED single lights is 70-75 This (the total is 210-675LED single lights). When a LED single light fails, it will only affect one set of signals. The remaining groups will be reduced to 2/3 (67%) or 8/9 (89%). , Will not make the entire signal lamp head fail like the incandescent lamp. The main problem of the LED traffic signal module is that the cost is still higher. Taking the 12-inch TS-Algaas red LED traffic signal module as an example, the earliest applied to 1994, its cost was 350 $, and in 1996, the performance was better in 1996. The Algainp LED traffic signal module, the cost is 200 $. It is expected that the price of Ingan blue -green LED traffic signal module will not be compared with Algainp in the future. Although the cost of the incandescent transportation signal light head is low, the power consumption is large. The power consumption of a 12 -inch incandescent traffic signal head in diameter is 150W. The incandescent signal lamp at the crossroads consumes 18133kWh per year, which is equivalent to 1450 $ each year. At 20W, the LED logo at the turn of the crossroads can be displayed with an arrow switch. The power consumption is only 9W. According to calculations, each crossroads can save 9916kWh each year, which is equivalent to 793 $ each year. According to the average cost of each LED traffic signal module 200 $, the red LED traffic signal module only uses the electricity fee saved, and after 3 years, the initial cost cost can be recovered, and economic returns are constantly getting economic returns. Therefore, using the Algainp LED traffic information module, although the cost seems to be a matter, from a long perspective, it is still cost -effective.
