LED market develops towards good products and diversification

Last year China LED industry sales income reached 2. 4 billion beauty yuan than 2003 growth 30 above. This year LED market and in the first half of all the way sing boom degree is self-evident. Therefore, the mainland has high brightness (HB) LED, LED lights, LED display screen suppliers are optimistic, and actively invest in capacity expansion and new product research and development. The production and research and development of HBLED are in full swing. HBLED accounts for about 30% of the total LED industry in mainland China. The output of mainland HBLED reached 3 billion in 2003 and about 4 billion in 2004. The growth in demand for outdoor displays, portable PCs, mobile phones, household appliances and automobiles has helped the HBLED industry in mainland China achieve good results last year, and these areas are expected to continue to drive demand growth this year. The continued prosperity of the HBLED market is prompting manufacturers to implement expansion plans. At present, manufacturers are stepping up efforts to increase production capacity, purchase new equipment, and even build new factories. Ningbo Shengpu optoelectronic semiconductor Co. , Ltd. has maintained an annual growth rate of 30% in the past few years. Company manager Chen Fusheng believes that this year will continue to maintain such a growth rate. The company, as well as its Ningbo Hepu light Electronics Co. , Ltd. and Ningbo Amida Electronics Co. , Ltd. , are mainly engaged in the research and development and production of LED products. products include HBLED, SMDLED, high power LED, infrared LED and photodiode, LED display screen and LED pixel lamp. At present, the company can produce 60 million LEDs per month, an increase of over last year. Chen Fusheng said: We will continue to expand production capacity, and next month's production capacity will reach 80 million. The company has allocated US $2 million to purchase automatic LED graders and testing equipment from Japan and Hong Kong, and is considering investing in additional SMD equipment and molding tape equipment this year. Last year, HBLED sales of Shenzhen Lanke Electronics Co. , Ltd. increased by 30. The company said: We believe that sales will increase by another 30 by the end of this year. In order to meet the growing demand of LED lighting industry, the company has increased the monthly production capacity of HBLED from 70 million to 0. 1 billion, and will invest in LED production in Shenzhen and Shantou by the end of the year. once completed, the production capacity will increase by another 20. Zhang Wei, business manager of Jiaguang Electronics Co. , Ltd. , said that HBLED sales increased by 15. 5% last year. The company mainly produces LED lamps, SMDLED, character and dot matrix LED display screens, LED backlights, pixel lamps and infrared LEDs. Major customers include well-known enterprises such as Amoi, Haier and ZTE. Zhejiang Hangzhou Chuangyuan Optoelectronic Technology Co. , Ltd. , which only started production of HBLED last year, will invest 4 million US dollars to produce high-power LED this year. The company's general manager, Lou mane, expects an annual production capacity of 50 million units next year. Haining Huaning Light Bulb Co. , Ltd. is very optimistic about the market prospect and will also devote itself to HBLED production. General Manager Zhang Feng confirmed: our HBLED production line is under construction. At present, the LED industry in mainland China still takes GaN-based LED chips as the mainstream, and mainly uses AlInGaP-based chips to produce high-power LED. Manufacturers can produce white, blue, red, yellow and green HBLED. Compared with traditional incandescent lamps and halogen bulbs, HBLED has the advantages of long service life, low power consumption and low heat generation, and is more environmentally friendly. HBLED is expected to replace all lighting products in current homes in the next 5 to 10 years, especially if technological improvements improve brightness. Therefore, suppliers began to shift their research and development focus to high power, high brightness and patch LED. Jiaguang electronics believes that high brightness and high power LED will become the trend, so this will be the company's research and development focus. Shenzhen Lanke electronics will also continue to develop high-power LEDs with higher luminous intensity, and plans to develop 30 ~ 50lm LED. Hangzhou Chuangyuan Optoelectronics has built a high-power HBLED production line with complete IPR, and has developed 1 W, 3 W, 5W and 10WLED with brightness as high as 30lm. Ningbo Shengpu is also developing high-power and SMDLED, with an annual investment of nearly 100 thousand US dollars in LED research and development. The company is also considering adopting a transparent substrate LED chip technology developed in Taiwan, which is expected to significantly improve the luminous intensity of LEDs. For blue, green and white LEDs, the company will also focus on improving their luminous intensity. At present, the flip-chip technology developed by Taiwan partners has greatly improved the heat dissipation and luminous intensity of the product, and has improved the life of blue and white LEDs. In addition to the heavy investment of the manufacturers themselves, the Chinese government has also given a lot of support and has listed high-power LED semiconductors as one of the major scientific and technological research projects in the 10th Five-Year Plan. The government also provides financial support to 11 universities and a number of research institutes engaged in research and development of ultra-high brightness LED and White LED in the mainland. The research work includes basic technology research, substrate materials, MOCVD equipment and components. At present, universities and research institutions are working to improve HBLED, blue and green LED and White Lighting LED. 12
