世界七大led芯片制造商的技术优势（The technological advantages of the worlds seven largest LED chip manufacturers） This article is contributed by hcd425 The worlds three major lighting industries - General Electric (GE), PHILPS (Phillips), OSRAM (Osram) The technological advantages of the worlds seven largest LED chip manufacturers 1, CREE (CREE) CREE is a market leading manufacturer and innovator of semiconductor, to significantly improve the solid state lighting, power and communications products for energy to improve their value. CREEs market advantage stems from the companys unique knowledge of materials in SiC (GaN) silicon carbide to manufacture chips and complete sets of devices. These chips and devices can be used in a very small space with greater power, while less exothermic than other existing technologies, materials, and products. CREE energy regression solutions for a variety of purposes, including the light emitting diode general lighting brighter and adjustable backlight, more vivid display, high current switching power supply and optimal power management of variable speed motor, there are exciting alternatives and wireless infrastructure etc more data and voice communication the effective. Crees customers have from innovative lighting manufacturers to defense related federal agencies. CREEs product range includes blue and green LED chips, lighting LED, backlight LED, light-emitting diodes for power switching devices, radio frequency equipment and radio equipment. Technological advantage 1, SiC based group III nitride epitaxial and chip level packaging technology; 2 、 high power chip and package technology. 2008-2009 years of business conditions In 2008, CREE achieved annual revenue growth of 25%, reaching $493 million, of which sales of LED products for $415 million, total revenue of 84%. acquisition of INTRINSIC and COTCO and the investment on the part of marketing to sales management costs increased by 44% compared to 2007; because of the hidden assets depreciatio
