摘要： Constructive occlusion type lighting systems utilize a reflective mask to cover a portion of an active optical surface, typically a Lambertian surface formed by the aperture of a diffusely reflective cavity, in order to distribute radiant energy with a tailored intensity distribution. Adjustment of the parameters of the constructive occlusion system enables the system designer to tailor the system performance to a wide range of applications. As disclosed herein, the constructive occlusion type distribution is combined with a diffuse distribution of a transmissive component, emitted through a wall of the system. For example, a diffusely reflective wall of the cavity may also be partially transmissive, to allow some energy to pass through and provide an additional illumination component, while continuing to maintain the characteristics to support the constructive occlusion component.

摘要： A lighting apparatus includes a source of light of a first spectral characteristic, a reflector or a diffusely reflective chamber or cavity having a transmissive optical passage, and a liquid containing quantum dots. The quantum dots provide a wavelength shift of at least some light emitted by the source of light to produce a desired second spectral characteristic in the light output.
