MULTI-MODE LUMINAIRE AND MULTI-DISTRIBUTION LENS

摘要

A multi-mode luminaire includes at least two opposed apertures for distributing light from two light members in an upwardly and downwardly direction. A heat transfer member disposed within the luminaire and between the light members functions as a mounting surface and heat sink for one of the light members and as an optical surface for redirecting light from the second light member. The opticalsurface allows the second light member to face internally and substantially away froman aperture viewed by a user, while light from the second light member is directed through the aperture and toward the user, below a cut-off angle. A switch disposed on the luminaire housing is configured for modulating a plurality of settings for the light members wherein the control circuit is configured to control the light output as a function of the switch and an operative source disposed in communication with the control unit. A further luminaire includes a single homogenous component lens wherein first and second halves of the lens are selected for manipulating the light distribution of the luminaire. The various configurations of the lens profile, achieve a particular light distribution, dependent on the lens material.

1. A luminaire comprising:
a luminaire housing having a first aperture emitting light from a first light member and a second aperture emitting light from a second light member, wherein the first and second light members are separated by a heat transfer member and at least one of the light members is mounted on the heat transfer member; a switch having a first position and a second position configured to modulate a plurality of settings for the first and second light members; a control unit configured to control the light output from the first and second light members as a function of the switch; and an operative source disposed in communication with the control unit and configured to instruct the control unit to operate the luminaire through a plurality of modes.
