Open channel LED light fixture for indirect lighting

1. A light fixture comprising:

a) an elongated housing with a lower light channel with an open bottom;

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

c) elongated LED light engines positioned on the elongated support edges or structures 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;

d) an upper light channel juxtaposed to the lower light channel;

e) an elongated light engine positioned on a top surface and within the upper light channel for emitting light therefrom; and

f) a diffusion lens positioned over light emitting surfaces of the elongated light engine light engine that is positioned on the top surface and within the upper light channel.

2. The light fixture of claim 1 , 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.

3. The light fixture of claim 1 , wherein the diffusion lens is an asymmetric diffusion lens.

4. The light fixture of claim 1 , further comprising a diffusion lens cover that encloses the upper light channel.

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 a 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 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 diffusion lens positioned over light emitting surfaces of the elongated LED light engine that is positioned within the upper light channel.

8. 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.

9. The light fixture of claim 7 , wherein the diffusion lens is an asymmetric diffusion lens.

10. The light fixture of claim 7 , further comprising a diffusion lens cover that encloses the upper light channel.

11. A light fixture comprising:

a) an elongated housing that forms a 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 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 diffusion lens positioned over light emitting surfaces of the elongated LED light engine that is positioned within the upper light channel.

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

13. The light fixture of claim 11 , wherein the diffusion lens is an asymmetric diffusion lens.

14. The light fixture of claim 11 , further comprising a diffusion lens cover that encloses the upper light channel.
