The Performance and Application of Ultra -high Brightness LED

With the limitation of the brightness of the outdoor LED display screen, the high -brightness LED display screen will be reduced in the market. Although the high brightness has gradually become the past in the LED display industry, it is still very popular in other aspects. Now let's take a look at the performance and application of ultra -high brightness LED. First, the performance of ultra-high brightness LED: Compared with Gaasp-Gapled, the ultra-high brightness red A1GAASLED has a higher luminous efficiency. The transparent lining (TS) A1GAASLED (640nm) is close to 10LM/W. -Gapled 10 times larger. The color provided by the ultra-high brightness Ingaalpled is the same as the GAASP-GAPLED include: green and yellow (560nm), light green and yellow (570nm), yellow (585nm), light yellow (590nm), orange (605nm), light red (640nm red (640nm red red (640nm) Cure. Comparison of transparent substrate A1GAINPLED light emitting efficiency with other LED structures and incandescent light sources, Ingaalpled absorbing the luminous efficiency of the substrate (AS) is 101M/W, the transparent substrate (TS) is 201M/W, and within the wavelength range of 590-626nm It is 10-20 times higher than the luminous efficiency of Gaasp-GaPled; within the wavelength range of 560-570. Ultra-high brightness Inganled provides orchid light and green light. The wavelength range is 450-480nm, orchid green is 500nm, and the green is 520nm; its influence efficiency is 3-151m/W. Ultra -high brightness LED's current lumen efficiency has exceeded incandescent lamps with filter filter, which can replace incandescent lamps within 1W of power, and use the LED array to replace the incandescent lamp within 150W of power of 150W. For many applications, the incandescent lamps use filter to get red, orange, green and orchid color, and the same color can be obtained with ultra -high brightness LED. In recent years, the ultra -high brightness LED manufactured by Algainp materials and Ingan materials combine multiple (red, orchid, green) ultra -high brightness LED chip together. Including red, orange, yellow, green, and blue. At present, its light emitting efficiency has exceeded incandescent lamps, and the positive fluorescent lamp is close to. The brightness brightness is higher than 1000mcd, which can meet the needs of all -weather and full -color display outdoors. Using LED color screens can express the sky and ocean. The new generation of red, green, and blue super high brightness LED has reached unprecedented performance. 2. Application of ultra -high brightness LED: 1. Information indicator Lantern car signal indicator: The car indicator light is mainly direction, taillights, and brake lights on the outside of the car;. Ultra -high brightness LED is used in automotive indicators to have many advantages compared with the traditional incandescent lamp, and it has 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 bulb, far higher than the car's own work life, so the LED brake light can be packaged into a whole. The transparent substrate Al.gaas and ALINGAPLED have a high inflammation efficiency compared to the incandescent bulbs with filter filter, so that the LED brake lights and the direction light can work at a lower driver current. The typical driving current is only incandescent. 1/4 of the lamp, thereby reducing 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 capacity. The response time of the LED brake lamp is 100NS, which is shorter than the response time of the incandescent lamp, so that the driver has left more response time, thereby improving the safety guarantee of driving. The illumination and color of the external indicator of the car clearly specify. Although the internal illumination of the car is not controlled by the relevant government departments like the external signal light, the manufacturer of the car has requirements for the color and illumination of the LED. GAPLED has been used in the car, and the ultra -high brightness Algainp and Inganled can meet the requirements of the manufacturer in terms of color and illumination. From the price point of view, although the LED light is still more expensive than the incandescent lamp, from the perspective of the entire system, the price of the two is not significantly different. With the practical development of ultra -high brightness TSALGAAS and Algainpled, prices have been decreasing in recent years, and the decrease in the future will be larger. Traffic signal instructions: Use ultra -high brightness LED to replace incandescent lamps 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 to install traffic signal lights. At least 12 red, yellow, and blue -green signal lights are required at the intersection of each crossroad. There are also some additional transformation signs at the crossroads and cross -road warning lights across 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 nationwide. At present, the use of ultra -high brightness LED replaced the traditional incandescent light to reduce power loss has achieved significant effects. Japan consumes about 1 million kilowatts on the traffic signal lamp each year. After using an ultra -high -brightness LED to replace incandescent lamps, its power consumption is only 12%. The competent authorities of each country must formulate corresponding specifications in each country. The color of the signal, the minimum lighting intensity, the pattern of the beam space, and the requirements for the installation environment, etc. Although these requirements are written according to incandescent lamps, the ultra -high brightness LED traffic signal lights currently adopted 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. At present, the ultra -high brightness ALGIINP red, orange, and yellow LED has been industrialized, and the price is relatively cheap. If the module composed of red ultra -high brightness LED replaces the traditional red incandescent traffic signal head, the red incandescent lamp can be safely failed due to the red incandescent lamp. The impact caused by the minimum degree. Generally, the LED traffic signal module consists of a number of LED single lights connected by several groups. Taking a 12-inch red LED traffic signal module as an example, the number of LED single lights connected in 3-9 groups in 3-9 groups is 70-75 This (the total is 210-675LED single lights). When a LED single light fails, it will only affect a set of signals. The remaining groups will be reduced to 2/3 (67%) or 8/9 (89%) , Will not make the entire signal lamp fail like incandescent lamps. The main problem of the LED traffic signal module is that the creation 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. 12 British AlgainpleD traffic signal module, the cost is 200 $. It is expected that it will not be a long time in the future, the price of Ingan blue -green LED traffic signal module will be compared with Algainp. Although the cost of the incandescent traffic 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 annual power consumption of the incandescent signal lamp at the crossroads is 18133kWh, which is equivalent to 1450 $ each year. 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 $ 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 the initial cost cost can be recovered after 3 years, and the economic return will be continuously obtained from the economic return.
