The successful and mature application of LED is its application in monochromatic light (red, blue and green). As an indicator light, it has been used in household appliances, electronic instruments and electrical equipment, and its usage rate has reached more than 95%. As a traffic light Due to the power consumption and information volume of incandescent bulbs, LED lights are gradually being replaced; as the large screen display of stadiums and public places, LEDs are the leader. The main applications of the development of power LED monochromatic light include landscape decorative lighting, LCD backlighting, car signal lights, etc. As the light efficiency continues to increase, its usage rate will increase rapidly. In short, LED lamps have unparalleled advantages in monochromatic applications compared to other lamps, of which red LEDs cannot be ignored.
LED white light applications are still in development, and they are not as good as other lamps in terms of light efficiency and color rendering. In the long run, it is difficult to replace other lamps. Recently, the popular application of L ED white light is green solar LED street lighting. As a solar-powered solar water heater, it is not a green energy-saving device. However, as a light-to-electrical conversion LED lamp, it is required to store electrical energy. It is only suitable for remote areas that cannot be powered. It is not necessary for a city with convenient power supply, and the large use of batteries in the city will inevitably pollute the environment. How can this be said to be green? From the current level of light efficiency of white LEDs, it is still lower than the fluorescent and sodium lamps used in roads. How can this be said to be energy-saving? It can be seen that the current application of white LEDs needs to be calm and rational.
The gap between China's LED industry and foreign technology is relatively large, but the gap between epitaxial chips is larger and the package gap is smaller. The biggest difference in epitaxial chips is InGaAlP red, orange, and yellow LEDs. At present, domestic products still use the epitaxial chip structure of the 1990s. The luminous efficacy of red light is generally only 10Lm/W, and the high-light using wafer bonding technology. The effect (20Lm/W or more) epitaxial chip is still in the blank in China, and all the required products are dependent on imports. What is worrying is that China's InGaAlP red, orange and yellow LED industry has long been neglected. InGaN blue-green optical epitaxial chip is targeted at white light illumination applications. Although it is strongly supported and developed as a major scientific and technological project, it still has a large gap with foreign countries. At present, the high-efficiency effect of the upper and lower electrodes using wafer bonding technology (>60Lm/W) There are no domestic products for power-type epitaxial chips.
China's LED packaging industry has developed rapidly in recent years. Some large-scale manufacturers of high-end LED products have some technical flaws in technology, but most of them are imitation and cloning of similar products overseas. Low-end LED package products are mostly produced by small factories and hand workshops. The price is low and the number is large, which is the highest in the world. The low-end products of epitaxial chips required by the LED packaging industry are oversupply, and the high-end products are difficult to obtain. They are based on regions or bases. They are fighting each other, low-level repetition, fierce competition, and the possibility of domestic LED enterprise integration becoming bigger and stronger. Sexuality.
In short, the development of China's LED industry should be InGaAlP red, orange, yellow and InGaN blue-green light simultaneously; LED application not only emphasizes semiconductor lighting, but also should take into account many other applications of LED; China's LED industry is strong across regions It is only possible to achieve this when the alliance is dominated by the market and breaks the limits of regional economic division. In China's vigorous development of the semiconductor lighting industry, more need to be calm, rational and reflective.
