Abstract

A lighting device includes a housing, a plurality of clips, a ferromagnetic strip, a light source, and a lens. The housing includes a base, a first side wall, a second side wall defining an interior cavity. Each of the plurality of clips is coupled to the housing and includes a magnet. The ferromagnetic strip is coupled to the housing via the magnets of the plurality of clips. The light source is disposed within the interior cavity of the housing and coupled to the ferromagnetic strip. The lens is disposed within the interior cavity of the housing.

Claims (43)

1. A lighting device comprising:

a housing including a base, a first side wall, a second side wall defining an interior cavity;

a plurality of clips, each of the plurality of clips being coupled to the housing and including a magnet;

a ferromagnetic strip coupled to the housing via the magnets of the plurality of clips;

a light source disposed within the interior cavity of the housing and coupled to the ferromagnetic strip;

a lens disposed within the interior cavity of the housing;

the first side wall of the housing includes a first flange extending into the interior cavity and the second side wall of the housing includes a second flange extending into the interior cavity;

each of the plurality of clips includes a base, a first deflectable arm, and a second deflectable arm; and

the first deflectable arm of each of the plurality of clips includes a first hook configured to engage the first flange and the second deflectable arm of each of the plurality of clips includes a second hook configured to engage the second flange to couple the one or more clips to the housing.

2. The lighting device of claim 1 , wherein each of the plurality of clips comprises a polymer material.

3. A lighting device comprising:

a housing including a base, a first side wall, a second side wall defining an interior cavity;

a plurality of clips, each of the plurality of clips being coupled to the housing and including a magnet;

a ferromagnetic strip coupled to the housing via the magnets of the plurality of clips;

a light source disposed within the interior cavity of the housing and coupled to the ferromagnetic strip;

a lens disposed within the interior cavity of the housing;

the first side wall of the housing includes a first flange extending into the interior cavity and the second side wall of the housing includes a second flange extending into the interior cavity; and

a power cable configured to deliver electrical power from a power supply to the light source, wherein a first portion of the power cable is disposed within the internal cavity of the housing and extends between the first deflectable arm and the second deflectable arm of at least one of the one or more clips.

4. The lighting device of claim 3 , wherein the base of the housing includes aperture and a second portion of the power cable extend through the aperture outside of the internal cavity of the housing.

5. The lighting device of claim 3 , wherein a first end of the power cable includes a connector.

6. The lighting device of claim 5 , wherein the plurality of clips includes a first clip and a second clip and the connector is disposed within the internal cavity of the housing between the first clip and the second clip.

7. The lighting device of claim 1 , wherein the lens comprises a flexible material.

8. The lighting device of claim 1 , wherein the lens comprises a rigid material.

9. The lighting device of claim 1 , wherein the lens comprises polymethyl methacrylate (PMMA).

10. The lighting device of claim 1 , wherein the first side wall of the housing includes a first protrusion extending into the internal cavity and the second side wall of the housing includes a second protrusion extending into the internal cavity.

11. The lighting device of claim 10 , wherein a first side of the lens includes a first groove configured to engage the first protrusion and a second side of the lens includes a second groove configured to engage the second protrusion to couple the lens to the housing.

12. The lighting device of claim 1 , further comprising one or more double-sided adhesive strips configured to couple the light source to the ferromagnetic strip.

13. The lighting device of claim 1 , wherein the light source includes a plurality of light emitting diodes (LEDs) coupled to a support substrate, wherein the support substrate is coupled to the ferromagnetic strip.

14. The lighting device of claim 1 , further comprising a first end cap coupled to a first end of the housing and second end cap coupled to a second end of the housing.

15. The lighting device of claim 14 , wherein the housing includes an upper groove extending between the first end and the second end of the housing, the first end cap includes a first tongue configured to engage the upper groove to aid in coupling the first end cap to the first end of the housing, and the second end cap includes a second tongue configured to engage the upper groove to aid in coupling the second end cap to the second end of the housing.

16. The lighting device of claim 1 , wherein the ferromagnetic strip includes a protective coating comprising a zinc and aluminum alloy.

17. The lighting device of claim 1 , further comprising a heat sink bracket configured to aid in transferring heat generated by the light source from the ferromagnetic strip to the housing, wherein a first portion of the heat sink bracket is positioned between the light source and the ferromagnetic strip and a second portion of the heat sink bracket directly contacts the first side wall or the second side wall of the housing.

18. The lighting device of claim 3 , wherein the lens comprises a flexible material.

19. The lighting device of claim 3 , wherein the lens comprises a rigid material.

20. The lighting device of claim 3 , wherein the lens comprises polymethyl methacrylate (PMMA).

21. The lighting device of claim 3 , wherein the first side wall of the housing includes a first protrusion extending into the internal cavity and the second side wall of the housing includes a second protrusion extending into the internal cavity.

22. The lighting device of claim 21 , wherein a first side of the lens includes a first groove configured to engage the first protrusion and a second side of the lens includes a second groove configured to engage the second protrusion to couple the lens to the housing.

23. The lighting device of claim 3 , further comprising one or more double-sided adhesive strips configured to couple the light source to the ferromagnetic strip.

24. The lighting device of claim 3 , wherein the light source includes a plurality of light emitting diodes (LEDs) coupled to a support substrate, wherein the support substrate is coupled to the ferromagnetic strip.

25. The lighting device of claim 3 , further comprising a first end cap coupled to a first end of the housing and second end cap coupled to a second end of the housing.

26. The lighting device of claim 25 , wherein the housing includes an upper groove extending between the first end and the second end of the housing, the first end cap includes a first tongue configured to engage the upper groove to aid in coupling the first end cap to the first end of the housing, and the second end cap includes a second tongue configured to engage the upper groove to aid in coupling the second end cap to the second end of the housing.
