摘要
详细分析了照明用大功率LED的封装技术,在大量实验的基础上,提出了一些具体的解决方案,设计了独特的封装结构。介绍了在色度稳定性与均匀性、改善散热条件等方面所作的探索,并对LED驱动电流和发光色温的关系进行了讨论。
Packaging techniques of the white power LEDs for lighting have been analyzed in detail. On the basis of a great deal of experiments, several practical methods are introduced, and a unique package structure has been designed to meet the needs for the GaN blue LED chips. Some explorations are introduced about keeping the stability and uniformity of whiter LED's chroma and thermal treatment of power LED. The relationships between driving current and correlative color temperature for white LED have been discussed.
