LIGHTING ASSEMBLY

摘要

Lighting assembly comprising: an enclosure having an interior surface and a first transmissive area, the interior surface comprising a first surface area region and a second surface area region generally opposite the first surface area region, wherein the first transmissive area is within first surface area region, and wherein the second surface area region includes a surface area generally opposite the first transmissive area that is at least one of semi-specularly reflective or diffusely reflective and has an on-axis average reflectivity of at least 90% for visible light of any polarization, and the remainder of the interior surface area has an on-axis average reflectivity of at least 98% for visible light of any polarization; a light guide disposed within the enclosure and between the first and second surface area regions, including substantially between the first transmissive area and the surface area generally opposite the first transmissive area that is at least one of semi-specularly reflective or diffusely reflective, the light guide including a first opening for receiving light, wherein the first opening does not extend between the first transmissive area and the surface area generally opposite the first transmissive area that is at least one of semi-specularly reflective or diffusely reflective; and a first light source positioned to introduce light into at least the first opening of the light guide.
