| Title: |
Directly Viewable Luminaire |
| Abstract: |
A luminaire comprising a housing having thermally separate compartments
for an electronics portion and a lighting portion. These thermally
separate compartments can provide thermal isolation between the
electronics portion and the lighting portion. The lighting portion
comprises a plurality of light-emitting elements and further includes an
optical device comprising two linear diffuser elements and can be used to
further improve the light emission characteristics of the light-emitting
elements thereby providing a directly viewable luminaire wherein the
illumination produced by point light sources appears uniform along the
length of the luminaire. A power supply for supply of energy to the
light-emitting elements and a controller for controlling application of
energy from a power source to the light-emitting elements is provided in
the electronics portion and can be thermally separated within the
electronics portion.
