Abstract: Application of a wavelength conversion element is substantially independent of the fabrication of a side-emitting light emitting device. In an example embodiment, the wavelength conversion element is situated around the periphery of a non-wavelength converting lightguide that is situated above the light emitting surface. One or more specular and/or diffusing reflectors are used to direct the light in the lightguide toward the wavelength conversion element at the periphery. In another embodiment, an interference filter may be used to provide predominantly side-emitted light at interfaces between the elements of the light emitting device.

Abstract translation: 波长转换元件的应用基本上与侧发光发光器件的制造无关。 在示例实施例中，波长转换元件围绕位于发光表面上方的非波长转换光导的周边。 使用一个或多个镜面反射器和/或扩散反射器将光导中的光引向外围的波长转换元件。 在另一个实施例中，可以使用干涉滤光器来在发光器件的元件之间的界面处主要提供侧发光。
