              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。 &nbs...

  • 照明用LED封装创新探讨

    ledlszm

           是LED照明灯具其制造都应采用多芯片封装和模组封装(模组封装是一种高密度的多芯片封装),而且最好是LED芯片直接封装在灯具主体上,这样热阻的道数最少,可以取得较好的散热效果。或者在灯具主体上制成敷有铜箔的线路体,其热阻也较低,LED照明的功率至少也要几瓦以上,所以都是多芯片使用,以往的封装工艺就不适用,必须采用新的方法和工艺。采用多个封装好的LED器件来组装LED灯具,很难造出高质量和高可靠的LED灯具的,希望从事LED灯...
