Car signal indicator: The car indicator light is mainly direction, taillights, and brake lights on the outside of the car; the inside of the car is mainly the lighting and display of various instruments. Ultra -high brightness LEDs are used in automotive indicators to have many advantages compared to traditional incandescent lamps and have a wide range of markets in the automotive industry. LED can withstand strong mechanical impact and vibration. The average working life MTBF is a few magnitude higher than the incandescent light bulb, far higher than the work life of the car itself. Therefore, the LED brake light can be packaged into a whole without considering maintenance. The transparent substrate Al.gaas and ALINGAP LED have a high influence efficiency compared to the incandescent bulb with filter, so that the LED brake lights and the direction light can work at a lower driver current. The typical driving current is only the only driving current. 1/4 of the incandescent lamps reduced the car for driving distance. The lower electrical power can also reduce the volume and weight of the internal line system of the automotive. At the same time, it can also reduce the internal temperature of the integrated LED signal light, allowing lens and outer to use plastic with low temperature resistance. The response time of the LED brake lamp is 100NS, which is shorter than the response time of the incandescent lamp. This leaves more response time for the driver, thereby improving the safety guarantee of driving. The illuminance and color of the external indicator of the car are clearly stipulated. Although the internal illumination of the car is not controlled by the relevant government departments like external signal lights, the manufacturer of the car has requirements for the color and illumination of LEDs. GAP LED has long been used in the car, and the ultra -high brightness Algainp and Ingan LED will replace the incandescent lamp in the car because they can meet the requirements of the manufacturer in terms of color and illuminance. In terms of price, although LED lights are more expensive compared to incandescent lamps, from the perspective of the entire system, the price of the two is not significantly different. With the practical development of ultra -high brightness TS Algaas and Algainp LEDs, prices have been decreasing in recent years, and the decrease in the future will be greater.

Traffic signal instructions: Use ultra -high brightness LED to replace incandescent lights for traffic signal lights, warning lights, and logo lights. According to the statistics of the US transportation department in 1994, there are 260,000 cross intersections installed in the United States. At least 12 red, yellow, and blue -green signal lights are required at the intersection of each crossroad. There are also some additional changes and cross -travelers on the road. In this way, there can be 20 signal lights at each crossroad, and it must be glowing at the same time. This can be estimated that about 135 million traffic signal lights across the country. The use of ultra -high brightness LED to replace the traditional incandescent light to reduce power loss has achieved significant results. Japan consumes about 1 million kilowatts on the traffic signal light each year. After using an ultra -high -brightness LED to replace incandescent lamps, its power consumption is only 12%of the original.

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.
