Inspur Huaguang: LD, LED go hand in hand
(China Lighting Network Special correspondent Yan Yimin) Shandong Langchao Huaguang Optoelectronics Co., Ltd., with a registered capital of 325 million yuan, is the first high-tech enterprise in China to introduce production MOCVD equipment, specializing in the development and production of compound semiconductor epitaxial wafers and optoelectronic devices. . Inspur Huaguang has a complete industrial chain. It is the only company in the same industry in China that has full-color LED, civilian LD epitaxial material preparation, die production, device packaging and application products. It is the largest laser diode in China. Chip manufacturers are in a leading position in the domestic optoelectronics industry. The main products are: semiconductor high-brightness light-emitting diodes (LED) and civilian laser diode (LD) epitaxial wafers, chips, devices and applications.
First, LD products dominate the market
Inspur Huaguang is the only company in China that has a complete production line of semiconductor lasers (LD). Since its establishment in 1999, its semiconductor laser diode die and high-power lasers have consistently ranked first in the domestic market, and are truly domestic semiconductors. The leader in the laser industry.
From the scientific research results, Inspur Huaguang has "a method for fabricating a semiconductor laser masking film", "a method for packaging a low- and medium-power semiconductor laser", and an asymmetric structure of an aluminum-free active region 808nm high-power quantum. 8 invention patents related to semiconductor lasers such as “well laserâ€; 7 scientific research achievements including “Zn diffusion window process for preparing high-power 300mW/650nm semiconductor laserâ€, “635nm red laser epitaxial wafer and die manufacturing technologyâ€, technical level All have reached international advanced and domestic leading.
From the perspective of product performance indicators, the company's 808nm laser technology advancement represents the highest level of China's semiconductor lasers. On the basis of strengthening the stability of 200mW 808nm laser products, the company has developed 300mW, 500mW, 1W-3W products, realized multi-band, full range of semiconductor laser supply market, and focused on breaking the material of Watt-class laser in research and development. Restricted (epitaxial material), successfully developed a single-tube 3 watt, 5 watt 808nm laser, and entered the market in batches; the company developed and produced 20W, 40W, 60W 808nm single-bar semiconductor laser array and 120W, 240W, 360W 808nm semiconductor laser Integrated array is the only manufacturer in China that develops and manufactures independently from chip to device. The company develops and produces 20mW, 300mW, 500mW 650nm semiconductor lasers and integrated array fiber output 1W-3W series products, which is the only one from chip to device in China. The 650nm semiconductor laser is independently developed and produced by the manufacturer.
In terms of product types, Inspur Huaguang laser diode products include 650nm laser diode die, 5mW 650nm TO-18 package laser diode, 300mW high power 635, 650nm TO-3, C-mount laser diode, 200m Watts, 300 mW TO-18 package 808nm laser diode, 500 mW, 1 watt, 2 watt, 3 watt, 5 watt 808nm TO-3, C-mount laser diode, 980nm laser diode series, etc., a wide range of products, A full range of products, but also undertake the development and design of a variety of new products.
Second, LED products are famous all over the world
Inspur Huaguang's semiconductor high-brightness light-emitting diode (LED) epitaxial wafers and chip performance indicators are at the domestic leading level, with a market share of 12%, and production and sales rank second in the country, of which the market share of red light chips is 25%. Production and sales ranked first in the country.
From the performance indicators, Inspur Huaguang independently developed and produced white LED luminous efficiency of 100Lm / W, 10 * 23mil2 blue chip optical power of 28mW, have reached the domestic leading level; the company uses SiC substrate development of semiconductor lighting extension The film and chip are listed in the National 863 Project, becoming the only company with this technology in China, with technical indicators reaching 350mW; the high-end products specially developed for outdoor full-color display P-series red light epitaxial wafers have increased optical power by more than 30%. Has replaced the imported products; W series ultra-high brightness red LED chip is the result of the National Ministry of Industry and Information Technology project, greatly improved the brightness, technical indicators have reached the international advanced level, the product has been widely used in traffic lights, LCD backlights, vehicle lighting In other fields, it has become the leading product in the domestic high-end market.
From the perspective of production capacity, Inspur Huaguang produces 450,000 LED epitaxial wafers and 6 billion chips of various types. The huge production capacity guarantees the stability of customers' supply.
At present, the Olympic Games and the World Expo have opened the prelude to the great development of the semiconductor lighting industry. Macroeconomic policies and local incentive policies at all levels have also provided a superior policy environment for the development of the semiconductor lighting industry. Inspur Huaguang will also take advantage of this, and relying on its own advantages in production, research and research and strong capital strength, it will certainly enable Inspur Light semiconductor lighting products illuminate every corner of the world.
