简单介绍了目前国内大功率LED芯片的现状,对部分产品进行了详细的封装研究,结果显示,国产芯片在光效方面提升迅速,最高已达110 lm/W,主流水平位于90～100 lm/W之间,但与进口产品相比都还存在较大差距;各个厂家的芯片封装的LED光源显色指数高低不一,其主要原因是芯片的峰值波长不同;在性价比方面,国产芯片价格已达到每百流明2元以下,具有较强的竞争力。 The current status of high power LED chips in China is introduced briefly. The detailed packaging studies on some products are carried out. The results show that the domestically produced chips have been rapidly upgraded in terms of luminous efficiency up to 110 lm / W, with the mainstream at 90-100 lm / W, but compared with the imported products are still a big gap; various manufacturers of LED chip package LED light color index varies, the main reason is the peak wavelength of different chips; in terms of cost, the domestic chip prices have been Up to 2 yuan per lumen to achieve the following, with strong competitiveness.
