具有均匀厚度的光学修饰元件的发光器件

Light emitting device having an optical modification element with uniform thickness
摘要：
A light emitting device is disclosed herein. An embodiment of the light emitting device includes a cavity and at least one light emitter located within the cavity. A first transparent material fills at least a portion of the cavity and encapsulates the light emitter. A substantially rigid optical modifying element is located adjacent the first transparent material, the modifying element comprises particles that emit at least one first wavelength of light upon being illuminated by a second wavelength of light. The modifying element has a first side located adjacent the first transparent material and a second side located opposite the first side, wherein the first side is substantially flat. In addition, the modifying element is substantially uniform in thickness.
摘要（中）：

本文公开了一种发光器件。 发光器件的一个实施例包括空腔和位于空腔内的至少一个光发射器。 第一透明材料填充空腔的至少一部分并封装光发射器。 基本上刚性的光学修饰元件位于第一透明材料附近，修饰元件包括在被第二波长的光照射时发射至少一个第一波长的光的粒子。 修改元件具有位于第一透明材料附近的第一侧和与第一侧相对的第二侧，其中第一侧基本上是平的。 此外，改性元件的厚度基本上是均匀的。
