摘要： A high luminous flux warm white solid state lighting device with a high color rendering is disclosed. The device comprising two groups of semiconductor light emitting components to emit and excite four narrow-band spectrums of lights at high luminous efficacy, wherein the semiconductor light emitting components are directly mounted on a thermal effective dissipation member; a mixing cavity for blending the multi-spectrum of lights; a back-transferred light recycling member deposited on top of an LED driver and around the semiconductor light emitters; and a diffusive member to diffuse the mixture of output light from the solid state lighting device. The solid state lighting device produces a warm white light with luminous efficacy at least 80 lumens per watt and a color rendering index at least 85 for any lighting application.

摘要： A solid state directional lighting device includes a semiconductor light source emitting a primary short wavelength light and a light collimation component disposed in light-reflecting relation to the light source to generate a collimated light with beam divergence angle less than forty degrees (40°). A luminescent nanocrystal conversion layer is disposed in the path of the collimated light and includes a luminescent nanocrystal conversion layer including luminescent nanocrystal particles with nano-particles sizes less than fifteen nanometers (15 nm). The luminescent nanocrystal particles absorb at least a portion of the collimated short wavelength light and convert the absorbed light into at least one long wavelength spectral light. A mixture of leakage primary short wavelength light and long wavelength light converted by the luminescent nano-particles produces a directional white light with luminous efficacy of at least one hundred lumens per Watt (100 lm/W). Light scattering is reduced due to the nano-particle size.

摘要： A semiconductor lighting device includes a semiconductor light emitter packaged on a reflective substrate to emit a first light and a remote wavelength conversion layer on a back-transferred light path to convert the back-transferred first light into a forward second light. A filter is disposed on a light emitting forward path with a space to the semiconductor light emitter to reflect back at least a portion of the first light.
