一种倒装HV‑LED光源及其制备方法
摘要：
本申请公开了一种倒装HV‑LED光源及其制备方法，其中，所述倒装HV‑LED光源的反射膜和金属层共同构成了所述倒装HV‑LED光源中的HV‑LED芯片的反光面，提升了HV‑LED芯片的光源利用率，从而提升了所述倒装HV‑LED光源的出光效率；另外，所述倒装HV‑LED光源中的封装层与所述基板表面所成角度为预设角度，为所述HV‑LED芯片提供了一个反光杯结构，使得所述HV‑LED芯片的出射光线在其出射光路上能够被该反光杯结构反射向所述倒装HV‑LED光源的出光面，从而进一步增强所述倒装HV‑LED芯片的出光效率。
摘要（英）：

The invention discloses an inverted HV-LED light source and a preparation method thereof. A reflecting surface of an HV-LED chip in the inverted HV-LED light source is together formed by a reflecting film and a metal layer of the inverted HV-LED light source, so that the utilization rate of the light source of the HV-LED chip is improved, and thus the luminous efficiency of the inverted HV-LED light source is improved; in addition, an angle between an encapsulation layer in the inverted HV-LED light source and the surface of a substrate is a preset angle, and a reflection cup structure is provided for the HV-LED chip, so that the emergent ray of the HV-LED chip can be reflected to the light emitting surface of the inverted HV-LED light source on an emergent light path of the emergent ray by the reflection cup, and thus the luminous efficiency of the inverted HV-LED light source is further improved.
