Abstract

The present solution provides a light fixture having an asymmetric optic configured to illuminate multiple surfaces of an enclosure. The light fixture can be attached to a location adjacent to and above a first shelf of a plurality shelves of the enclosure. The optic can split light from the light source to form a first light beam directed to the first shelf and form a second light beam directed to a second shelf of the plurality of shelves. The second shelf can be below the first shelf. The first light beam can have a first predetermined intensity and the second light beam has a second predetermined intensity different than the first predetermined intensity.

Claims

1. A system, comprising:

a light fixture comprising a light source, wherein the light fixture is configured to be attached to a location adjacent to and above a first shelf of a plurality of shelves;

an optic of the light fixture comprising an interior portion having a first angle to form a first light beam and a second angle to form a second light beam, the optic configured to split light from the light source to form the first light beam directed to the first shelf and form the second light beam directed to a second shelf of the plurality of shelves, the second shelf below the first shelf,

wherein the first light beam formed via the first angle has a first intensity and the second light beam formed via the second angle has a second intensity greater than the first intensity.

2. The system of claim 1, wherein the optic is further configured to form the first light beam with the first intensity and the second light beam with the second intensity based on a ratio.

3. The system of claim 2, wherein the ratio is based on a first distance between the optic of the light fixture and the first shelf, and a second distance between the optic of the light fixture and the second shelf, the second distance greater than the first distance.

4. The system of claim 1, wherein the optic is further configured to form the first light beam with the first intensity and the second light beam with the second intensity based on a ratio of 1 to 3.

5. The system of claim 1, wherein the light source comprises one or more light emitting diodes (LEDs) configured to emanate light via the optic.

6. The system of claim 1, wherein the light source comprises a plurality of light emitting diodes (LEDs) aligned to direct light to the optic.

7. The system of claim 1, wherein the light source comprises a plurality of light emitting diodes (LEDs) configured to direct light to the optic, a first LED of the plurality of LEDs aligned in a first direction, and a second LED of the plurality of LEDs aligned in a second direction different from the first direction.

8. The system of claim 1, wherein the optic comprises an asymmetric optic configured to form the first light beam directed to the first shelf and form the second light beam directed to the second shelf.

9. The system of claim 1, wherein the optic comprises an exterior portion that is symmetric, and the interior portion adjacent to the light source that is asymmetric.

10. A method, comprising:

providing, in an enclosure comprising a plurality of shelves, a light fixture having a light source and an optic having an interior portion with a first angle to form a first light beam and a second angle to form a second light beam;

attaching the light fixture to a location in the enclosure adjacent to and above a first shelf of the plurality of shelves, the optic of the light fixture configured to split light from the light source to form the first light beam directed to the first shelf and form the second light beam directed to a second shelf of the plurality of shelves, the second shelf below the first shelf,

wherein the first light beam formed via the first angle has a first intensity and the second light beam formed via the second angle has a second intensity greater than the first intensity.

11. The method of claim 10, wherein the optic forms the first light beam with the first intensity and the second light beam with the second intensity based on a ratio.

12. The method of claim 11, wherein the ratio is based on a first distance between the optic of the light fixture and the first shelf, and a second distance between the optic of the light fixture and the second shelf, the second distance greater than the first distance.

13. The method of claim 10, wherein the optic forms the first light beam with the first intensity and the second light beam with the second intensity based on a ratio of 1 to 3.

14. The method of claim 10, wherein the light source comprises one or more light emitting diodes (LEDs) configured to emanate light via the optic.

15. The method of claim 10, wherein the light source comprises a plurality of light emitting diodes (LEDs) aligned to direct light to the optic.

16. The method of claim 10, wherein the light source comprises a plurality of light emitting diodes (LEDs) configured to direct light to the optic, a first LED of the plurality of LEDs aligned in a first direction, and a second LED of the plurality of LEDs aligned in a second direction different from the first direction.

17. A method, comprising:

splitting, by an optic of a light fixture comprising an interior portion having a first angle and a second angle, light emanated from a light source to form a first light beam via the first angle with a first intensity and a second light beam via the second angle with a second intensity greater than the first intensity, the light fixture attached adjacent to and above a first shelf of a plurality of shelves in an enclosure; and

directing, by the light fixture, the first light beam to the first shelf and the second light beam to a second shelf, the second shelf below the first shelf.

18. The method of claim 17, wherein the optic comprises an asymmetric optic that forms the first light beam directed to the first shelf and forms the second light beam directed to the second shelf.

19. The method of claim 17, wherein the optic comprises the interior portion having a first angle to form the first light beam and a second angle to form the second light beam, wherein the second light beam formed via the second angle has a greater intensity than the first light beam formed via the first angle.
