  • Publication number: 20190041036
    Abstract: 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.

  • Publication number: 20180299100
    Abstract: A luminaire module delivers light with a beam angle of ?. The luminaire module includes a light emitting module and a reflector positioned symmetrically about an axis. Light produced by the light emitting module exits the light emitting module from one or more spatially-extended light emitting portions. The light emitting portion(s) is (are) fully contained within a spatially extended notional design envelope which is used to guide the design of reflector and its corresponding reflective surface, such that when any light exiting the light emitting portions through the design envelope strikes the reflective surface of the reflector, the light does not return to the source and escapes from the luminaire module within a beam angle ?, with no more than a single reflection from a reflector.
