[] Xie Mingxun: high efficiency AC LED technology

Jingyuan Au Optronics Co deputy general manager Xie Mingxun at the third session of the international new light & New Energy Forum (INLES 2009) on a report entitled "high efficiency AC light-emitting diode technology" report.

Xie Zong first introduced the circuit design, ACLED technology and product level, and focuses on the analysis of the design criteria, single chip ACLED design process and key technology; then Xie Zong from ACLED to improve the efficiency, from three aspects of changes and the heat generated by the power supply system describes the technical challenges faced by ACLED; finally, Xie Zong that ACLED is a complete system, the use of DCLED is convenient for customers, eliminating the design of many circuit on time and cost, although the luminous efficiency of ACLED is not DCLED, but ACLED to shorten the gap with the DCLED is not impossible, believe that by epitaxial structure, cell design and optimization the process of ascension, in time, the ACLED must be in the lighting market will light.
