Abstract

An LED light fixture is disclosed with an elongated housing that forms a open lower light channel and an upper light channel that is juxtaposed to the open lower light channel with electronics cavity or conduit positioned there between. The LED light fixture preferably has an elongated reflective insert that extends through the open lower light channel and creates a reflection channel from which the indirect and reflected light is emitted and a detachable cover structure that includes a diffusion lens and a removable baffle structure that attaches to side walls of the upper light channel.

Claims (24)

1. A light fixture comprising:

a) an elongated housing with a lower light channel with an open bottom and upper light channel juxtaposed to the lower light channel;

b) opposed elongated support edges or structures positioned near bottom edges of the open bottom;

c) elongated LED light engines positioned on the elongated support edges or structures and positioned near the bottom edges of the open bottom, wherein light emitted from the elongated LED light engines into the lower light channel is reflected out through the open bottom; and

d) a detachable cover structure positioned over the upper light channel, wherein the detachable cover structure includes a H-shaped support feature with a diffusion lens and a removable baffle structure.

2. The light fixture of claim 1 , wherein arms of the H-shaped support feature have sets of snap features that attach to side walls of the upper light channel and matched groove features on the removable baffle.

3. The light fixture of claim 1 , further comprising an elongated light engine positioned on a top surface and within the upper light channel for emitting light therefrom.

4. The light fixture of claim 3 , wherein the elongated light engine that is positioned on the top surface and within the upper light channel includes sets of linear arrays of LEDs.

5. The light fixture of claim 1 , further comprising an elongated electronics cavity or conduit positioned between the lower light channel and the upper light channel.

6. The light fixture of claim 1 , further comprising an elongated reflective insert that extends through the lower light channel and creates a reflection channel within the lower light channel.

7. A light fixture comprising:

a) an elongated housing that forms an open lower light channel and an upper light channel that is juxtaposed to the open lower light channel with an electronics cavity or conduit positioned there between;

b) elongated LED light engines positioned on support edges or structures within the open lower light channel for emitting indirect and reflected light out from the open lower light channel;

c) an elongated LED light engine positioned within the upper light channel; and

d) a detachable cover structure includes a H-shaped support feature with arms bridged by a diffusion lens and a removable baffle structure.

8. The light fixture of claim 7 , wherein the arms of the H-shaped support attach to side walls of the upper light channel and to matched groove features on the removable baffle structure.

9. The light fixture of claim 7 , further comprising an elongated reflective insert that extends through the open lower light channel and creates a reflection channel from which the indirect and reflected light is emitted.

10. A light fixture comprising:

a) an elongated housing that forms an open lower light channel and an upper light channel that is juxtaposed to the open lower light channel;

b) elongated LED light engines positioned on support edges or structures within the open lower light channel for emitting indirect and reflected light out from the open lower light channel;

c) an elongated LED light engine positioned within the upper light channel;

d) an elongated reflective insert that extends through the open lower light channel and creates a reflection channel from which the indirect and reflected light is emitted; and

e) a detachable cover structure that includes a H-shaped support feature with arms bridged by a diffusion lens and a removable baffle structure, wherein the arms have sets of snap features that attach to side walls of the upper light channel and matched groove features on the removable baffle.

11. The light fixture of claim 10 , wherein the elongated housing has an electronics cavity or conduit positioned between the open lower light channel and an upper light channel.
