    摘要： An LED lamp or bulb is disclosed that comprises a light source, a heat sink structure and an optical cavity. The optical cavity comprises a phosphor carrier having a conversions material and arranged over an opening to the cavity. The phosphor carrier comprises a thermally conductive transparent material and is thermally coupled to the heat sink structure. An LED based light source is mounted in the optical cavity remote to the phosphor carrier with light from the light source passing through the phosphor carrier. A diffuser dome is included that is mounted over the optical cavity, with light from the optical cavity passing through the diffuser dome. The properties of the diffuser, such as geometry, scattering properties of the scattering layer, surface roughness or smoothness, and spatial distribution of the scattering layer properties may be used to control various lamp properties such as color uniformity and light intensity distribution as a function of viewing angle.

    摘要： Apparatuses and methods for producing light emitting devices maximizing luminous flux output are disclosed. In one possible embodiment, a light emitting device comprises a substrate and a reflective layer at least partially covering the substrate. The reflective layer is non-yellowing, and may be substantially light transparent. One or more light emitting diode (LED) chips are disposed on the substrate. The light emitting device may emit white light. The reflective layer may comprise a silicone carrier with light reflective particles dispersed in the silicone carrier. A light diffusion lens may also be disposed on the substrate and surrounding the LED chips. Furthermore, one or more microspheres, light scattering particles, and/or phosphor particles may be dispersed in the lens. In one possible method for producing a light emitting device, a substrate is provided. One or more LED chips are coupled with the substrate, and a high reflective, non-yellowing coating is applied on at least a portion of the top surface of the substrate. The coating comprises a carrier with reflective particles dispersed throughout.

    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.
