技术介绍
目前,随着LED材料外延和芯片工艺的发展,LED显示了良好的应用前景,特别是 大功率LED,其应用领域不断拓展,已被广泛应用在景观照明、矿灯、路灯、应急路灯等领域。LED是一种特殊的二极管,其核心部分是由P型半导体和N型半导体组成的芯片, 这些半导体材料预先通过注入或掺杂等工艺生产P/N结结构。在某些半导体材料的P/N结 中,LED中的电流可以轻易地从P极流向N极,两种不同的载流子即空穴和电子在不同的电 极电压作用下从电极流向P/N结,当空穴和电子相遇而产生复合,电子会跌落到较低的能 阶,同时以光子的方式释放出能量,而给P/N结加反向电压,少数载流子难以注入,故不发 光。目前,大功率LED封装结构中,LED的出光率不高,同时LED的散热效果差,影响 LED的使用寿命。
