Linear luminaire with optical control
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.
1. 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.
2. The linear luminaire of claim 1 , wherein the lens is a single-piece seamless lens.
3. The linear luminaire of claim 1 , wherein the distribution of the first light is more even after passing through the over-optic piece.
4. The linear luminaire of claim 1 , wherein the first over-optic piece is removably attached to the housing.
5. The linear luminaire of claim 1 , wherein the multiple LEDs of the down-light LED light source are attached to the first circuit board and wherein the multiple LEDs of the up-light LED light source are attached to the second circuit board.
6. The linear luminaire of claim 1 , wherein the housing is approximately 4 feet long.
7. The linear luminaire of claim 1 , wherein the over-optic piece comprises two or more over-optic pieces that are linearly coupled to each other.
8. The linear luminaire of claim 1 , further comprising a first driver that provides power to the down-light LED light source and a second driver that provides power to the up-light LED light source.
9. The linear luminaire of claim 1 , further comprising a driver that provides power to the down-light LED light source and to the up-light LED light source.
10. The linear luminaire of claim 1 , wherein the down-light LED light source is spaced from the up-light LED light source.
