COB packaging star Zhonghao Optoelectronics achieved breakthroughs in R&D and mass production of flip-chip COB products, and exhibited the CPT gold-free COB series products at the Hong Kong Spring Lighting Fair.
This series of products are mainly used in commercial and outdoor lighting. From the technical parameters and application scenarios, it is quite bright.
Commercial photo COB: high display refers to high-density output, suitable for small-angle optical design
The series of products named BD1914-0512I30W*G specializes in commercial lighting. It can achieve 850mA current on the 14mm luminous surface COB, reaching 30-50W level, achieving Ra>80 and luminous efficiency of 130lm/W. Compared with the traditional formal COB, not only the reliability is greatly improved, but also the higher the power density, the system cost can be reduced.
At the same time, this high-power density COB light-emitting surface is small, which can facilitate small-angle optical design, is compatible with international brand general product series, and provides optical supporting services with different needs. Can be applied to all kinds of high-end commercial, home lighting field lighting products.
Outdoor COB: high reliability, compatible with traditional bracket type product interface
The two products exhibited OD46248-0810Q50W*P and OD46248-1210Q80W*P specializing in outdoor applications. The two outdoor flip-chip gold-free COB products use a square superconducting aluminum substrate of 46mm and a luminous surface of 24.8mm, which is compatible with traditional brackets. Product interface, which can directly replace the integrated module.
This series of products adopts superconducting aluminum substrate, which can effectively dissipate heat and effectively eliminate silver vulcanization and blackening. It also has the high reliability advantages of high power density integrated products, and can be widely used in outdoor lighting.
