Lighting using natural light

摘要

Embodiments described herein generally relate to re-using the energy of natural light. In some examples, a lighting unit is described. An example lighting unit can include a multiple number of bound light-conductive members. A long-lasting phosphorescent material can be dispersed between the multiple number of bound light-conductive members. A luminance of the lighting unit can be at least several thousand cd/m2.

1. A lighting unit, comprising:
a housing with a cavity extending from a waveguide at a first end to a light outlet at a second end; a lighting assembly located in the cavity, the lighting assembly comprising:
a plurality of bound light-conductive cores extending between the waveguide and light outlet; anda phosphorescent material dispersed between and contacting the plurality of bound light-conductive cores; and a diverging lens positioned in the housing between the first end and the lighting assembly, wherein a luminance of the lighting unit is at least several thousand candela per square meter (cd/m2).
