降低散热成本 打破LED灯具高价障碍

          实际LED芯片成本只有15%,其它成本主要来至封装、散热、结构成本、电源。从成本的组成来看降低灯具成本是在制造环节,单纯要求LED芯片降低是起不到太大的作用。灯具制造需要整体价格合理,规划合理,综合性的单纯要求某一个部分便宜作用不大,而是我们设计的灯具整体架构要经济,是最优化的最重要。散热成本要维持在20%,20%成本认为很合理,最大的问题是怎样更有创新,设计更合理。
          结构设计在灯具中大概占电源是LED灯具最薄弱的环节,严重滞后LED灯具发展,品质有待提高。现在设计占灯具成本的20%左右,有些高。随着技术发展电源大概在5-10%最为合理。
实际散热设计很简单,把住两个方向:
         LED芯片与外散热器件路径越短越好,越短你的散热设计就越好;
