Last year, China's LED industry sales revenue reached 2.4 billion US dollars, an increase of more than 30 than in 2003. This year, the LED market has been singing all the way in the first half of the year, and the level of prosperity is self-evident. Therefore, mainland high-brightness (HB) LED, LED lights, LED display suppliers are optimistic, and actively invest in capacity expansion and new product development. HBLED's production and R&D are in full swing. HBLED accounts for about 30 billion of the total LED industry in mainland China. In 2003, the output of HBLED in the mainland reached 3 billion, and the output in 2004 was about 4 billion. Demand for outdoor displays, portable PCs, mobile phones, home appliances and the automotive sector has grown, helping the mainland's HBLED industry to achieve good results last year, and these areas are expected to continue to drive demand growth this year. The continued boom in the HBLED market is prompting manufacturers to implement expansion plans, and now manufacturers are stepping up their capacity, purchasing new equipment, and even building new ones. Ningbo Shengpu Opto Semiconductors Co., Ltd. has maintained an annual growth rate of 30 in the past few years. Company manager Chen Fusheng believes that this growth rate will continue this year. The company and its Ningbo and Spectrum Optoelectronics Co., Ltd. and Ningbo Amyida Electronics Co., Ltd. are mainly engaged in the research and development and production of LED products, including HBLED, SMDLED, high power LED, infrared LED and photodiode, LED display and LED. Pixel light. The company currently has 60 million LEDs per month, and its output has increased by 50 compared with last year. Chen Fusheng said: We will continue to expand production capacity, and the monthly production capacity will reach 80 million next year. The company has allocated $2 million to purchase automatic LED classifiers and test equipment from Japan and Hong Kong, and is considering investing in SMD equipment and forming tape equipment this year. Last year, Shenzhen Lanke Electronics Co., Ltd. increased the sales of HBLED by 30%. The company said: We believe that sales will increase by 30 by the end of this year. In order to meet the growing demand of LED lighting industry, the company will have monthly capacity of HBLED. 70 million will be raised to 100 million, and LED production will be invested in Shenzhen and Shantou by the end of the year. Once the capacity is completed, it will increase by 20. The business manager of Jiaguang Electronics Co., Ltd. Zhang Wei said that HBLED sales increased by 15. The company mainly produces LED lights, SMDLED, character and dot matrix LED display, LED backlight, pixel light and infrared LED. The major customers include Amoi, Haier and ZTE. Zhejiang Hangzhou Chuangyuan Optoelectronics Technology Co., Ltd., which started production of HBLED last year, will increase its investment of 4 million US dollars to produce high-power LEDs this year. The company’s general manager Lou Manyu expects to have an annual production capacity of 50 million next year. Haining Huaning Light Bulb Co., Ltd. is very optimistic about the market prospects, and will also be involved in HBLED production. General Manager Zhang Feng confirmed: Our HBLED production line is under construction. At present, the LED industry in mainland China still uses GaN-based LED chips as the mainstream, and mainly uses AlInGaP-based chips to produce high-power LEDs. Manufacturers can produce white, blue, red, yellow and green HBLEDs. Due to HBLED and traditional incandescent Compared with halogen bulbs, the lamp has the advantages of long life, low power consumption and low heat generation, and is more environmentally friendly. It is expected that HBLED will replace all the lighting products in the current residence in the next 5 to 10 years, especially if the technology improves. If the brightness is improved. As a result, suppliers are beginning to shift their R&D focus to high-power, high-brightness and SMD LEDs. Jiaguang Electronics believes that high-brightness and high-power LEDs will become a trend, so this will be the company's research and development focus. Shenzhen Lanke Electronics will continue to develop high-power LEDs with higher luminous intensity, and plans to develop LEDs of 30~50lm. Hangzhou Chuangyuan Optoelectronics has built a high-power HBLED production line with complete IPR, and developed 1W, 3W, 5W. With 10WLED, the brightness is up to 30lm. Ningbo Shengpu is also developing high-power and SMDLED, and the annual investment in LED research and development is nearly 100,000 US dollars. The company is also considering the use of 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 its luminous intensity. At present, the use of flip chip technology developed by Taiwan partners has greatly improved the heat dissipation and luminous intensity of the products, and improved the life of blue and white LEDs. In addition to the manufacturers' own heavy investment, the Chinese government has also given a lot of support, and has listed high-power LED semiconductors as one of the major scientific research projects in the 15th plan. The government also provides financial support to 11 universities and research institutes engaged in research and development of ultra-high-brightness LEDs and white-light LEDs in the mainland, including basic technology research, substrate materials, MOCVD equipment and components. Universities and research institutes are currently working to improve HBLED, blue and green LEDs and white LEDs.12
