Abstract: A plurality of display portions are illuminated in different colors using a light source of a single type and a single light guide plate. A light source (220) has a light emitting element for emitting blue light, and a red fluorescent substance which is excited by blue light to generate red light, thereby emitting violet light (L1) as a whole. The violet light (L1) enters a side surface of a light guide plate (210) and is emitted from an upper surface (211) and a lower surface (212) as violet light (L1-1) and (L1-2), respectively. A green fluorescent substance is provided in a fluorescent film (230). The light (L2) obtained after the violet light (L1-1) passes through the fluorescent film (230), becomes white light because green color component light generated from the fluorescent substance is mixed with the violet light (L1-1). On the other hand, on a lower surface side, the violet light L1-2 is used as illuminating light.

Abstract: A high bay induction fluorescent lighting fixture having a multiple of nested circular lamps suspended on a post below the ballasts therefor and enclosed in a reflector.

Abstract: This invention provides a lighting fixture for use in low-ceiling applications and/or outdoor environments, such as parking garages that allows for the use of more-efficient lighting sources, such as fluorescent lamps, with more-even distribution of light along the sides of the fixture so that the surrounding space is fully and efficiently illuminated. Two elongated light sources are mounted upon opposing sides, and surrounded by a pair of respective side reflectors. The side reflectors direct the light of the two light sources in a generally sideward and somewhat-downward direction. The lower portion of the side reflectors collectively define an overall wide angle and each lower portion completely overlies a respective one of the side light sources mounted above. A third light source can be located centrally, beneath the lower portions to provide downward light, which is further reflected generally downwardly by the wide angled lower portions.
