摘要：
An LED used for plant illumination, comprising a substrate (11), a PN-junction light-emitting part arranged on the substrate (11). The light-emitting part has a strained light-emitting layer with component formula of GaXIn(1−X)AsYP(1−Y) (0<；X<；1 and 0<；Y<；1). The light-emitting part has a barrier layer, forming a 2˜40-pair alternating-layer structure with the strained light-emitting layer. The structure adopts a new light-emitting material GaXIn(1−X)AsYP(1−Y), which can significantly improve the light-emitting efficiency by 50%-100%.
