GaN基交流高压大功率LED芯片及其灯具的研制
Development of Alternating-Current-Driven GaN-Based High-Voltage High-Power LED Chips and Its Lamp
摘要
Abstract
This paper presents the design and preparation of the alternating current high voltage chip ( AC-HV chip) based GaN, and elaborates the critical process of its preparation, and its characterization of the performance with I-U-L curve and near-field patterns distribution. The result indicated that the AC-HV chips had good performance. After assembled as lamps with current limit resistor and packaged on frame based ceramic with two parallel and two series connection model, the performance of the lamps on the initial-state were compared with the steady-state.关键词
