LED (LightingEmittingDiode) illumination is LED illumination, which is a kind of semiconductor solid-state light-emitting device... LED (LightingEmittingDiode) illumination is LED illumination and is a semiconductor solid-state light-emitting device. It uses a solid semiconductor chip as a luminescent material, and in the semiconductor, composites emit excess energy to cause photon emission, and directly emit red, yellow, blue, green, cyan, orange, purple, and white light. LED lighting products are lighting fixtures that are manufactured using LEDs as light sources. Due to the emergence and rapid development of white LEDs (referred to as white LEDs), the government and businesses have paid great attention to them. White LEDs have the advantages of low voltage, low power consumption, high reliability, long life and solidification. Its greatest attraction and expectation is the fourth generation of new lighting sources after incandescent, fluorescent and high-intensity discharge lamps, with a huge lighting market and significant energy savings. In the context of the current global energy shortages, the energy conservation is an important issue for us in the future. In the field of lighting, the application of LED lighting products is attracting the attention of the world. LED is a new type of green light source. It is bound to be the trend of future development. In the 21st century, it will enter the era of new lighting sources represented by LED. The Chinese LED industry started in the 1970s. After more than 30 years of development, China's LED industry has initially formed a relatively complete industrial chain including LED epitaxial wafer production, LED chip preparation, LED chip packaging and LED product application. A lot: NVC lighting , rectangular lighting . Under the impetus of "National Semiconductor Lighting Project", seven national semiconductor lighting engineering industrialization bases in Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Yangzhou and Shijiazhuang were formed. The Yangtze River Delta, the Pearl River Delta, the Triangle and the North have become the gathering places for the development of China's LED industry. At present, the development of China's semiconductor lighting industry is improving, the development of epitaxial chip companies is particularly rapid, the scale of packaging enterprises continues to grow rapidly, and lighting applications have made great progress. In 2007, the output value of China's LED application products has exceeded 30 billion yuan. It has become the world's largest producer and exporter of LED full-color display, solar LED, landscape lighting and other applications. The emerging semiconductor lighting industry is taking shape. Domestically, it has formed certain characteristics in the field of lighting. Among them, outdoor lighting has developed the fastest. There are hundreds of LED street lamp companies and dozens of demonstration roads have been built, but they still lag behind in the indoor general lighting market. In 2003, the government launched the "Semiconductor Lighting Project" to promote the development of LED lighting for LED lighting in China. Taking Xiamen as an example, since Xiamen was officially identified as one of China's four major optoelectronic industrial bases in 2004, LED enterprises in Xiamen base It has grown from the initial 30 to the current 90. LED lighting is generally divided into three parts: front-end chip production, package production and lamp driver design and production. With the continuous improvement of LED chip technology, (power improvement, light extraction efficiency, ESD level improvement, etc.), LED lighting promotion Providing a good opportunity, taking Hualian Electronics, Optoelectronics , and Cinda Optoelectronics as examples, LED lighting development is gradually divided into three types of white LED applications, traditional bullet-type or hemispherical (LAMPLED) white light. LED, mainly used in outdoor screens, traffic signals, etc.; TOPLED production, this product in China including Xiamen is a relatively new product, most LED optoelectronics companies have plans or are on the product project, mainly used in indoor lighting , such as: LED table lamps, LED fluorescent lamps , automotive lighting, especially in the backlighting of flat-panel TVs is a hot topic; high-power LEDs can currently be produced in small batches of 3 watts, mainly used in outdoor lighting such as: street lights, tunnel lights. For the development of white LEDs in lighting, the most important ones are the development and mass production of white TOPLEDs and POWERLEDs. Based on the current situation, in the development of chips, wafers, Guolian, Sanan, Kerui, etc. can provide mass production chips. And also attach great importance to the current widespread research and development work on attenuation, antistatic ability, luminous efficiency, etc.; packaging companies such as Hualian Electronics, Guangpu Electronics, and Cinda Optoelectronics are on the list of TOPLED and POWERLED projects. Hualian Electronics has been producing small batches since 2006. Especially in nightscape projects and streetlights, there are practical examples in Xiamen, but considering the material selection and packaging technology of white LEDs and the comprehensive power of driving power supply. In the case of the actual use of white LEDs, there are still thermal design problems (affecting the light efficiency of the chip, such as: a large part of the light energy of the high-power LED is converted into thermal energy loss), and the design defects of the driving circuit cause the product to fail in operation. The proportion is relatively large. For example, many of the night scene projects in Xiamen are caused by the problem of the driving power supply, which causes the light to be off; However, in the use of luminaires, various production plants are still investing in research and development, especially in TOPLED, which has begun mass production in the city lighting such as fluorescent lamps. The current price is too high to prevent it from being used in civilian and other commercial applications. The only factor in the rapid growth of the industrial sector, the previous exchanges with various chip suppliers, the price of high-power LED chips is dropping at a rate of 30-50% per year, and it is expected to be 2-3 years later, LED lighting in civilian and other commercial Applications in the industrial sector will experience explosive growth, and the entire market has enormous potential beyond imagination. Front-end chip production, packaging production and lamp driver design and production have formed an industrial chain in Xiamen. At the current stage, especially the packaging factory, process quality control in TOPLED and POWERLED production is the key technology research, accumulating for mass production. Prepare for experience and quality improvement. The general process for LEDs used in packaging factory lighting is as follows: Loading--bonding--fluorescent coating--packaging--testing In process control, process control of film placement, glue height and chip integrity; thrust of gold ball solder ball, ball diameter, combination of second solder joint and plating layer, wire tension and breakpoint control; fluorescent glue Process control of precipitation and bubbles; process control of TG point after packaging and selection of test electrical parameter program, etc. Process control is closely related to the quality and batch effect of white LED products, especially in the factory to improve production efficiency and product quality. All use of automated equipment, process quality control during the period is more important. The concentrated display of LED lighting in the 2008 Beijing Olympic Games gave people a new understanding of LEDs and effectively promoted the development of China's semiconductor lighting industry. At present, China's semiconductor industry is large and not strong, and its core competitiveness still needs to be further improved. For domestic enterprises, it is the primary task to strengthen the product quality and technology level, improve the ability to obtain the price of the patent in the future, or gradually break through the core patent through research and development.
