The domestic LED lamp chip technology will be significantly improved in the next five years

Recently, Hella, a German manufacturer of automotive electronic systems and lighting systems, and Hubbell Lighting, a US company, have become strategic partners to promote Hella lighting technology outside the automotive industry in North America. According to preliminary calculations, there are approximately 34 million street lights in the United States that need to be replaced. The number of LEDs used in cars is even more incalculable. The LED demand for car lights is stimulating the development of the LED chip industry. In the next five years, the quality and output of LED chips in China will be significantly improved to meet this demand. Auto parts companies, auto parts offer With the rapid development of science and technology, now automotive lamps are gradually converted from traditional lights to LED lights. An LED is a solid semiconductor assembly containing a pn junction that can emit light by itself. The LED chip is a chip consisting of a p-type semiconductor and an n-type semiconductor. There is a transition layer between the p-type semiconductor and the n-type semiconductor, which is called a pn junction. When semiconductor materials such as gallium arsenide (infrared ray), arsenic phosphide (red to yellow), and gallium phosphide (green) are used, minority carriers and majority carriers injected in the pn junction of these semiconductor materials are used. When compounding, excess energy is released in the form of light, which converts electrical energy directly into light energy. Compared with traditional car lights, LED car lights have many advantages such as high light efficiency, no environmental pollution, energy saving, long service life, low heat, shock resistance, and high color purity.
