Recently, Xinhaiyi Holdings subsidiary Suzhou Xinnajing Optoelectronics Technology Co., Ltd. announced that the luminous efficiency of the white light chips produced by them has reached 185 lumens per watt. From this indicator, the chips produced by Xinnajing Optoelectronics have surpassed the absolute The technical standards of most manufacturers are at the domestic leading level.
It is understood that the world's current LED chip luminous efficiency is the highest in the United States Cree (Creek) company, in the 200l lumens per watt, domestic chip manufacturers of different levels, but few companies can reach 180l lumens per watt level. Xin Najing Optoelectronics was established by Xinhaiyi in 2011 and now accounts for 90% of the shares. The predecessor was Najing Optoelectronics, a subsidiary of Suzhou Nanotechnology Institute of the Chinese Academy of Sciences. The core team and technology are also from Dr. Wang Huaibing, the general manager of the Institute of Nanotechnology at the Chinese Academy of Sciences in Suzhou. He is a well-known expert in the field of LED epitaxy in China.
Wang Huaibing introduced that in addition to 185 lumens per watt, this technical indicator is leading in China. At present, the company's COB (chips on board) replaces the previous SMT patch, eliminating the need for a bracket, thus effectively solving the heat dissipation problem and making the use of the light source. Life expectancy has doubled. The light source production process can integrate 100 chips in a single time, and the yield rate is above 98%. The technical level and production process are also in a leading position.
In addition, the 69-piece and MOCVD machine of the German Aixtron brand with high epitaxial production efficiency on the market, because it is a 69-piece machine, is highly efficient, but the technical difficulty is also high. Currently, on a global scale, Almost no chip manufacturers have successfully commissioned and put into production. Wang Huaibing told reporters that Xin Najing has solved this technical problem and that the model has been put into mass production. This means that the amortization cost of Xinnajing's epitaxial wafers will be lower than that of similar enterprises, and the cost performance will be higher.
Insiders analyzed that with the gradual implementation of the “banned white road mapâ€, people’s understanding of LED lighting has become more and more in-depth. The LED market has entered a fast-rising channel since this year, and the new nano-crystals with the above several core technologies LED lighting may become the highlight of the next round of growth.
