  LED防爆灯材料及封装技能的不断升级改进,促进LED防爆灯产品亮度不断提高,LED防爆灯的运用越来越广,以LED防爆灯作为显示器的背光源,更是近来抢手的论题,首要是不同品种的LED防爆灯背光源技能分别在颜色、亮度、寿数、耗电度及环保诉求等均比传统冷阴极管(CCFL)更具优势,因而招引业者活跃投入。

  因为高亮度高功率LED防爆灯体系所衍生的热问题将是影响产品功用好坏要害,要将LED组件的发热量敏捷排出至周遭环境,首要有必要从封装层级(L1&L2)的热办理着手。现在业界的作法是将LED芯片以焊料或导热膏接在一均热片上,经由均热片下降封装模组的热阻抗,这也是现在市面上常见的LED封装模组,首要来历有Lumileds、OSRAM、CREE和Nicha等LED世界闻名厂商。

  散热问题是在LED防爆灯开发用作照明物体的首要妨碍,选用陶瓷或散热管是一个有用避免过热的办法,但散热办理解决方案使材料的本钱上升,高功率LED散热办理规划的意图是有用地下降芯片散热到终究产品之间的热阻,Rjunction-to-case是其间一种选用材料的解决方案,供给低热阻但高传导性,经过芯片附着或热金属办法来使热直接从芯片传送到封装外壳的外面。
