Recently, Jingrui Optoelectronics, founded by Dr. Liu’s entrepreneurial team, officially launched two high-efficiency high-power LED eutectic ceramic package products X3 and X4. These two products adopt high-power LED chip and FLIP CHIP chip with vertical structure of silicon substrate. The average light efficiency can reach 148lm/W and 150lm/W respectively under the driving current of 350mA; in the case of driving current 700mA The average light efficiency can reach 115lm/W.
High power led silicon substrate chip having a vertical structure suitable for large current drive, heat, good light emission topography, high reliability, low wire, etc., FLIP CHIP has a large light-emitting area of the chip, higher brightness, better heat dissipation , no gold wire process, high reliability and so on. Dr. Chen Zhen, Chairman of Jingrui Optoelectronics Co., Ltd. said that the high-power LED chip of silicon substrate with vertical structure is based on two considerations: First, the silicon substrate LED chip has independent intellectual property rights, is a veritable “Chinese coreâ€, and the second is silicon lining. The bottom high power LED chip is ideal for ceramic packaging and is suitable for high-end lighting. Similarly, FLIP CHIP chip is also very suitable for ceramic packaging. At present, FLIP CHIP's high-end eutectic ceramic package is rare, and Jingrui just uses its own technological advantages to seize technology and market.
The eutectic ceramic package is currently a high-end package in the industry, which has high technical requirements and technical difficulties. Zhou Zhiming, general manager of Jingrui Optoelectronics, said that Jingrui Optoelectronics has solved the technical difficulties of eutectic precision, phosphor coating and optical design with international leading low thermal resistance eutectic ceramic packaging technology and advanced lens technology. The high-efficiency package of the substrate high-power LED chip maximizes the advantages of the high-power LED chip of the silicon substrate, and also realizes the high-efficiency package of the eutectic ceramic of FLIP CHIP.
Compared with general ceramic packaging products, Jingrui Optoelectronics released two eutectic ceramic package high-power products with "one big, three low, four high" characteristics, namely high current resistance, low light decay, low thermal resistance, low voltage High luminous efficiency, high reliability, high heat dissipation, high cost performance, can be applied to high-end lighting such as LED street lights, tunnel lights, car headlights and mobile flash. It has been one of the earliest pioneers in the study of high-power LED packaging and applications in China.
He has twice established a high-power LED packaging and application company, and through continuous technological innovation and product structure adjustment, he has always provided customers with high-quality, cost-effective high-power LED packaging and application products. Under his leadership, the companies founded have developed into influential companies in the optoelectronics industry.
