High Brightness White Light LED Technology and Market Analysis

As the brightness increases and the price decreases, the market potential of the white light LED in the field of universal lighting is increasing. The use of white light LED in the general lighting industry will have a positive impact on the energy strategies and environmental protection strategies of the country or region. The white light L E d has a small volume, a plane packaging, or using multiple or multiple combinations according to the environment or condition, and has a low heat calor, long luminous life (more than 50,000 hours), not easy to break, extremely earthquake resistance and extremely shock resistance and extremely shock resistance and extremely shock resistance and extremely shock resistance and extremely shock resistance and extremely shock resistance and extremely shock to resistance and volatile and extremely shock -resistant and extremely shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very resistant to shock. Patient resistance can be used in harmful conditions and other characteristics. The white light LED light emitting efficiency is high, so many metals such as power saving, heat -free radiation, non -containing mercury, no pollution and waste treatment problems, etc., are regarded as the star of tomorrow with the "green lighting source". Replace the mainstream incandescent bulbs and fluorescence (daily) lights currently for the lighting market. The development of the white light LED lighting industry will affect the energy and environmental protection strategies of a country and region. Therefore, various countries have supported the example of the LED semiconductor lighting industry as a major national development. The white light LED market is the most optimistic of the LED industry with strong market potential lighting sources in the LED industry. According to FROST & SULLIVAN's estimates, the global lighting light source market has climbed a stable growth rate of 5%per year; of which, white light LEDs are more likely to enter the incandescent bulb and fluorescent light market. These two products are the most popular civil lighting. The light source, the market potential of the white light LED in the future can be said to be quite huge. 1. The white light LED light -emitting principle white light LED lighting method is mainly divided into two types: single crystal type and polycrystalline type using LED light -emitting diodes. The first is a single crystal type, that is, a monochrome LED light -emitting diode and the corresponding fluorescent powder, just like the lighting method of the sunlight, using LED light -emitting diode. There are usually two ways. One way is that the blue light LED glowing diode stimulates yellow fluorescent powder to produce white light. The other is the ultraviolet light LED stimulating RGB three -wave long fluorescent powder to produce white light. Many manufacturers are mainly engaged in the research of white light LEDs. They usually start developing and mass production from Blu -ray LED. With the technology of Blu -ray LED technology, Baiguang LED is developed. However The lighting efficiency of the blue light LED is still insufficient. Many manufacturers began to develop in another direction to develop in the ultraviolet light LED. Blue light is better. And the method of UV LED and RGB three waves of fluorescent powder, the key technologies in high -efficiency fluorescence synthesis, that is, how to effectively attach fluorescent powder to a technology. The other is polycrystalline, even if two or more complementary 2 -color LED light -emitting diode or 3 primary LED light -emitting diode are mixed to form white light. The multi -crystalline type of white light is used, because the driving voltage, light output, temperature characteristics and life span of different colors of LED light -emitting diodes are different. The method of generating white light in the type of LED is complicated. Because of the large number of LED light -emitting diodes, the cost of polycrystalline LED is also high. If a single crystal type is used The design on the drive circuit will be easier. Therefore, many manufacturers now use single crystal LEDs as white light LED development direction. 2. Marketing: LED technology has developed rapidly in recent years, brightness has continued to increase, and prices have continued to decrease. In addition to the original LED market, the market has continued to expand in general lighting. Both brightness and price have gradually approached the traditional source. Due to the turbulent situation in the world's oil -producing areas, the problem of global energy shortage has once again become the focus of attention. The development of the LED industry will have a huge impact on the energy and environmental protection policies of a region. The United States, Japan, Europe, and South Korea have all set up national -oriented R & D organizations to accelerate technology development and mass production. At this stage, there is still a long distance from the time to enter the era of white LED lighting. Due to the consideration and cost consideration of white light LED lighting efficiency and cost, about 100LM/W of white light LED in 2010, and 200LM/W in 2020. If the process of white light LED is accelerated, it can slowly appear commercialized products in 2005, and after 2010. In terms of the lighting market, according to FROST & SULLLIVAN's estimates, the global market size of the incandescent light bulb and solar lights in 2000 was about 4.3 billion US dollars, and the annual growth rate was about 5 %. It was about 2.5 times the global visible LED market size in 2000. Therefore, the development space of the lighting market is quite large. Reed Electronics Research Global White -ray LED is estimated to grow to a market size of $ 118 million in 2000. In the next three years, it will maintain a growth rate of about 40 %. In 2003, it reached a market size of $ 270 million. In the future, the cost of white light LED will be further reduced. Except for the existing mobile phone backlight and small -sized LCD backlight, if the market for universal lighting starts, the white light LED market will have greater market potential. White light LED is estimated to have been At first, the market energy will be gradually released, and the demand will gradually increase. At this stage, the application of white light LEDs is mainly used for reading lights, decorative lights, etc. in terms of lighting, and about 95%of the remaining 95%are for small -sized LCD backlighting sources. 1. The market with the screen back light source of the color mobile phone on the white LED market is the largest. Although the maximum use of white LED can be up to 100,000 hours, it must be operated in a low -current environment. At present, this product is mainly used for small -sized backlight sources. From the perspective of various application markets, because color screen mobile phones need to be paired with white light LED as the backlight source, and color screen mobile phones will become the development trend of the mobile phone market in the next few years. According to the industry's market forecast for color screen mobile phones, the proportion of color mobile phones in 2004 is about 40 % In 2005, it is estimated to reach 55%to 60%. About 5-1 billion pieces, in addition, because the white light LED has begun to use the flash of the mobile phone attached digital camera, the proportion of the mobile phone attached digital camera this year is about 15%, and it is expected to increase to 20%next year. 4 estimates, the demand for a year is about 400 million. Secondly, in terms of backlight sources in PDA and digital cameras, according to the estimated valuation of the Economic Capital Center of Zhuhai Industry Research Institute, PDA shipped about 25 million units in 2003, and each use of about 6-8 white light LEDs per unit. It is estimated that about 50 million pieces are required; if the digital camera is used, the number of digital cameras in 2003 in the world is about 30 million units. From this point of view, the demand for white light LED will still be based on the backlighting source market of color screen mobile phones. 2. White -light LED currently uses small -sized LCD backlight as its main cold cathode fluorescent light (CCFL) compared to other backlight technology technology has the advantages of brightness and high luminous efficiency. It is strict, but because the cold cathode fluorescent light of the small tube diameter is more difficult and the cost is not much advantage, the cold cathode fluorescent lamp is mostly used at 4 inches or more (and the size of the mobile phone is more than 1.5 inches to 2.2. In the inch, the digital camera is lightly considered and the size is between here). In terms of large -sized LCD backlight sources, the current cold cathode fluorescent lamp has an absolute advantage in terms of large size and price. Therefore LCD backlight source to use cold cathode fluorescence lamps. Therefore, the dividing point of the white light LED as the LCD backlight and the cold cathode fluorescent light as the LCD backlight is that the small -sized LCD uses white light LED, and the large and medium -sized LCD (such as LCD display, LCD TV) uses cold cathode fluorescent lights. For example, the brightness of the white light LED increases and the cost is further improved. In terms of large -sized LCD, the white light LED replaces the cold cathode fluorescent light as the backlight source. In this way, considering the market potential of large -sized LCDs in PC and TV, the demand for white light LED as a large -sized LCD backlight is very amazing. 3. The biggest of the white light LED market is the general lighting market industry that is most optimistic about the white light LED market is the general lighting market. At this stage, the white LED light emitting efficiency can reach 30LM/W (the ordinary incandescent bubble light emitting efficiency is 15LM/W), but the If the white light LED really occupies a certain market in the general lighting market, the efficiency of the white light LED luminescence needs to be improved to 60-100LM/W. From the perspective of luminous efficiency, once the white light LED exceeds 60lm/W (equivalent to equivalent to the equivalent 20W sunlight), you can start to be popularized in the lighting market. If you can increase efficiency to 80LM/W, it will be popularized to general home various lamps. However, in order to truly occupy the general lighting market, in addition to the fluctuation efficiency and power, the cost is also a very important factor. In terms of luminous efficiency and cost ratio, the cost of white light LED in 2001 is about $ 1/LM. In 2002, to $ 0.1/LM, if the cost can be reduced to $ 0.01/LM, because the white light LED belongs to green and environmentally friendly energy, it is expected that there will be most markets that can completely replace existing general lighting. Third, the patent issues involved in white light LED are currently high -brightness white light LEDs in the world: Nichia, ORSAM, Matsushita, Lumileds, Toyota Gosei, Stanley, Toshiba, Citizen. Do not use patent authorization to release technology. In terms of market competitiveness and positioning, Nichia, Toyota Gosei, Cree, Cree leaders in high -level technologies such as Blu -ray and white light, while European and American large manufacturers Lumileds and OSRAM are the most complete in vertical integration. As LEDs have special and general lighting, LEDs, LEDs, LEDs, LEDs The development of various aspects such as display screens, mobile phone backlight sources, so the layout of market development trend, sales channels and upstream and downstream raw materials and key industrial chains will be the key to improving market share in the market in large international manufacturers. In addition, Baiguang LED involved patent issues. Nichia successfully mass -produced GAN Blu -ray LEDs as early as November 1993, almost monopolized the entire Blu -ray market, but with the improvement of Toyota Gosei and CREE Blu -ray LED, Nichia has been threatened. Since 1996, Nichia has set off. A series of patent litigation disputes, because Nichia adopted a patented technology monopoly market with patent authorization technology, has been in trouble for patent technology. , CREE reached a reconciliation, was forced to start cross -authorization with the above -mentioned company, and could use specific patented technologies for both parties to end the six -year lawsuit. Nichia's patent monopoly basically draws an end. In October 2002, OSRAM authorized the white light LED manufacturing technology to ROHM, and observed that Nichia has not accused OSRAM and Rohm, Nichia's patent ice in recent years,. The lawsuit will spend time conducting infringement investigations, and a large amount of money will fall into the deep pockets of lawyers. Due to the surge in LED market demand, no company can dominate the market. Because the use of LED lighting affects the energy strategy and environmental protection strategy, all countries have a certain reservation attitude towards the Nichia patent lawsuit. This affects the results of the lawsuit that affects the patent of nichia to a certain extent. Select the materials for high -quality LED lamp beads, technology Co., Ltd.
