    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.

  • Patent number: 10126545
    Abstract: A color wheel assembly includes a color wheel fixed in a housing and a detecting apparatus for generating a synchronization signal. The color wheel is driven to rotate and has a marking object rotating with it. The housing has a first surface parallel to and adjacent a surface of the color wheel where the marking object is located. The first surface of the housing has a first through hole at a location within an annular region corresponding to the marking object when the color wheel rotates by one revolution. The detecting apparatus is disposed on the back side of the first through hole and a probe head of the detecting apparatus is disposed in the first through hole for detecting the marking object on the color wheel. The structure insulates the probe head from heat emitted from the color wheel. A related light source system is also disclosed.
