China has successfully developed the LED interior lighting with MCOB 2th, TCOB, cob packaging materials and technologyJanuary 31, Chinese Academy of Sciences, held in Putian, Fujian “LED interior lighting t5 t8 tubes with high-efficiency low-cost packaging materials with improved MCOB 2th, TCOB, cob technology integration” achievements appraisal meeting, the Committee agreed that the expert group, the technology has a complete independent intellectual property rights and has achieved large-scale industrialization, product technical indicators have reached the international advanced level.The group agreed that, through fundamental research and engineering applications of long-term research, the results of key materials by encapsulating the design and development, the formation of innovative new multi-functional materials based on improved, more cups, multi-chip (MCOB 2th, TCOB, cob) package integration technology, significantly improves the light efficiency, reduce costs, a major breakthrough in key materials and key technologies with independent intellectual property rights, and has achieved scale industrialization.Since 2009, Chinese Academy of Sciences and the Fujian Fujian Institute of structure wanban Optoelectronics Technology Co., Ltd. to collaborate on research and development MCOB 2th, TCOB, cob packaging materials and structures industrial manufacturing technology, and now, it developed a luminous efficiency of lighting products has reached the international advanced level, while only 30% of the market price of similar products. In 2012, use of the technology has achieved annual output of 1.5 million LED bulb and 1 million LED fluorescent tubes t5 lights t8 fluorecent tubes lights.The Group believes that the outcome of this is formed by the packaging material to package are complete independent intellectual property rights, including the four major innovations:First, the design and development of a multi-functional high-reflectance optical ceramic thin aluminum plate as MCOB 2th, TCOB, cob package substrate material, usually solves the presence of a silver film yellowing problem, breaking the thermal insulation barrier, improve the substrate reflectivity and light source efficiency, simplifying the assembly structure, reduce lighting costs more than a quarter of the total. MCOB 2th, TCOB, cob the substrate packaging technology to achieve a LED bulb entire lighting efficiency 153.37Lm per watt, color rendering index of 82.8, LED fluorescent strip the entire lighting efficiency 154.72Lm per watt, color rendering index of 70.2.Second, the first use of cast composite laminate molding process developed alumina composite ceramic substrate to achieve a combination of high diffuse reflectance and high thermal conductivity, high dielectric breakdown resistance, high reliability, performance and other advantages, effectively improve the efficiency of the light source and optical quality, low-reflection to solve the ordinary alumina ceramic substrate, low thermal conductivity problems. Application of the composite ceramic substrate MCOB 2th, TCOB, cob packaging technology to achieve a LED bulb entire lighting efficiency 149.97Lm per watt, color rendering index of 82.5, LED fluorescent strip the entire lighting efficiency 189.5Lm per watt, color rendering index of 69.8.Third, through the innovation process and the crystal field modulation techniques, a light-tunable wavelength, no surface defects, high quantum efficiency, low light transmittance close to the theoretical value of a new generation of fluorescent material – transparent ceramic garnet structure phosphor, using the new transparent ceramic phosphor were MCOB 2th, TCOB, cob package, significantly improves the light source reliability and efficiency, simplifying the assembly structure, reduce costs and solve the usual presence of phosphor and packaging adhesive caused by the aging of color drift and bad light problem. At the same time, the first time using a double-sided light package, low current drive to achieve a light source efficiency multi-chip packaging structure 261Lm per watt.Fourth, adoption of improved MCOB 2th, TCOB, cob technology integration (including the above three board after chip packaging technology and processing technology, power technology, ceramic cooling fins technology, high thermal primer technology, etc.) formed a low-cost, high-efficiency LED light source and lighting technology package , down more than a quarter of the cost of LED products, efficiency increased by 50%, leading international performance.The Group recommends the need to further accelerate the popularization and application of technology, especially the transparent phosphor ceramics technology for industrial application, and expand the industrial scale, in order to enhance the core competitiveness of China’s indoor like t5 t8 LED tubes lighting industry.
