摘　　要：COB器件在商业照明领域有着非常重要的应用,近年来其光效、光输出、光品质在不断提升,光效在未来仍然有较大的提升空间。先进材料和芯片技术对于提升光效至关重要。高密度级COB重新定义了商业照明的性能、尺寸、成本,并且帮助开发出之前不可能实现的新型照明解决方案。灯具小型化、小角度设计和高中心光强(CBCP)等,满足了商业照明的要求。光品质的提升,包括Ra、R9、Rf、Rg、特殊色点,针对不同的商业应用场合和照射环境需求,可实现媲美金卤灯或卤素灯光色的同时,提供优异的性能和光品质指标。COBs are widely adopted in commercial lighting. Efficacy, light output and hght quality oi COBs keep continuous improvements. The potential of efficacy is still large in the future. Advanced materials and chip technology are vital to improve efficacy. High density class COBs redefine performance, size and cost of commercial lighting and help to develop novel solution that could not be realized before. Minimization, smaller beam angle and higher CBCP are developed to meet requirements of commercial lighting. The improvements of light quality, including indexes of Ra, R9, Rf, Rg and specialty color points are optimized for various commercial lighting applications and light environments to provide halogen and CMH like appearances, excellent performance and premium color.
