Abstract
A linear luminaire includes a housing and a light emitting diode (LED) light source attached to the housing. The luminaire further includes an over-optic piece covering the LED light source, and a lens spaced from the over-optic piece and covering the over-optic piece from view. A distribution of a light provided by the luminaire through the lens depends on the over-optic piece.
Claims10
A linear luminaire, comprising:
- a housing;
- a down-light light emitting diode (LED) light source comprising a first circuit board attached to the housing, wherein the down-light LED light source is positioned in the housing to emit a first light toward an area below the linear luminaire;
- a first over-optic piece covering multiple LEDs of the down-light LED light source, wherein the first over-optic piece is attached to the housing and wherein the first over-optic piece is spaced from the multiple LEDs of the down-light LED light source;
- an up-light LED light source comprising a second circuit board separated from the first circuit board, wherein the up-light LED light source is positioned to emit a second light toward an area above the linear luminaire;
- a second over-optic piece covering multiple LEDs of the up-light LED light source, wherein the second over-optic piece is spaced from the multiple LEDs of the up-light LED light source;
- and
- a lens spaced from the first over-optic piece and covering the first over-optic piece from view, wherein the first over-optic piece changes a distribution of the first light as the first light passes through the first over-optic piece.
