发明名称 LED PACKAGES WITH SCATTERING PARTICLE REGIONS
摘要 An LED package comprises at least one LED that emits LED light in an LED emission profile. The LED package includes regions of scattering particles with the different regions scattering light primarily at a target wavelength or primarily within a target wavelength range. The location of the regions and scattering properties are based at least partially on the LED emission profile. The regions scatter their target wavelength of LED light to improve the uniformity of the LED emission profile so that the LED package emits a more uniform profile compared to the LED emission profile. By targeting particular wavelengths for scattering, the emission efficiency losses are reduced.
