为最大可能提高大功率LED路灯发光板的电光转化率与散热效率
在不影响外量子效率前提下对LED芯片设计采用扩大LED芯片面积
以及电极优化技术增加LED芯片的出光量
使芯片表面热流均匀分布
芯片工作更稳定。分析了大功率白光LED的封装过程对提高芯片取光率、保障白光质量、器件散热技术的综合应用。综合上述技术及有限元分析软件对大功率LED器件封装的热阻分析结果
确定了COB(chip on board)LED芯片的阵列组装技术
为制造LED路灯发光板的最佳技术方案。LED芯片结温很容易控制在120 ℃以下
与外部散热技术兼容性好。通过光线最佳归一化数学模型计算了LED芯片阵列芯片间最佳距离。最后通过对各种白光LED驱动方案的比较
确定了白光LED最佳驱动方案为恒电流驱动脉宽调制(PWM)调节亮度。
