    摘要： A variety of light-emitting devices for general illumination utilizing solid state light sources (e.g., light emitting diodes) are disclosed. In general, the devices include a scattering element in combination with an extractor element. The scattering element, which may include elastic and/or inelastic scattering centers, is spaced apart from the light source element. Opposite sides of the scattering element have asymmetric optical interfaces, there being a larger refractive index mismatch at the interface facing the light emitting element than the interface between the scattering element and the extractor element. Such a structure favors forward scattering of light from the scattering element. In other words, the system favors scattering out of the scattering element into the extractor element over backscattering light towards the light source element. The extractor element, in turn, is sized and shaped to reduce reflection of light exiting the light-emitting device at the devices interface with the ambient environment.

    摘要翻译： 公开了用于利用固态光源（例如，发光二极管）的一般照明的各种发光装置。 通常，这些装置包括与提取元件组合的散射元件。 可以包括弹性和/或非弹性散射中心的散射元件与光源元件间隔开。 散射元件的相对侧具有不对称的光学界面，在面向发光元件的界面处，与散射元件和提取元件之间的界面相比，折射率失配较大。 这种结构有利于来自散射元件的光的向前散射。 换句话说，该系统有利于通过向光源元件的反向散射光将散射元件散射到提取器元件中。 提取器元件又被确定尺寸和形状，以减少与设备与周围环境的界面处离开发光装置的光的反射。

    摘要： A variety of light-emitting devices are disclosed that are configured to output light provided by a light-emitting element (LEE). In general, embodiments of the light-emitting devices feature two or more light-emitting elements, a scattering element that is spaced apart from the light-emitting elements, an extractor element coupled to the scattering element, and a reflective element that is configured and arranged to reflect light emitted from the light-emitting elements.
