Abstract

A light strip that includes a housing with an elongated shape. A tray is attached to the housing and is positioned in the housing. An LED assembly is mounted to the tray and includes LED elements that emit light outward away from the tray. An elongated lens with a central section is configured to extend over the LED assembly. Inner end caps are positioned at ends of the lens with the inner ends caps being light-transmissive. Outer end caps are positioned at ends of the housing outward from the inner end caps with the outer end caps being opaque.

First claim

What is claimed is:

1. A light strip comprising:
a housing with an elongated shape having first and second ends;
a tray mounted to the housing;
an LED assembly comprising LEDs that emit light outward away from the housing and the tray, the LED assembly comprising an elongated shape with a first end positioned at the first end of the housing and a second end positioned at the second end of the housing;
light engine circuitry connected to the LED assembly;
a lens with an elongated shape that extends along the housing and is positioned over the LED assembly;
a first end cap mounted at a first end of the lens and a second end cap mounted at a second end of the lens, the first and second end caps configured to allow light to pass from the LED assembly and be emitted outward beyond the first and second ends of the housing; and
opaque outer end caps mounted respectively at the first and second ends of the housing, the outer end caps positioned outward from the first and second end caps.

2. The light strip of claim 1 , wherein the first and second end caps are translucent to allow the light emitted from the LED assembly to be emitted outward beyond the first and second ends of the housing.

3. The light strip of claim 1 , wherein the first and second end caps are aligned perpendicular to a back wall of the housing.

4. The light strip of claim 1 , wherein the housing comprises a back wall and a channel formed between outer walls that extend outward from a perimeter of the back wall, and the lens is attached to the tray at an open side of the housing opposite from the back wall.

5. The light strip of claim 1 , wherein the housing comprises a back wall, lateral side walls that extend along a length of the housing, and end walls at the first and second ends of the housing, the first and second end caps are aligned along a length of the housing in a non-overlapping arrangement with the end walls of the housing.

6. The light strip of claim 1 , wherein the outer end caps are larger than the first and second end caps and extend across the housing, the tray, and the lens.

7. The light strip of claim 1 , wherein the first and second end caps extend across the lens and are spaced away from a channel formed within the housing.

8. The light strip of claim 1 , further comprising a latch positioned in the housing and comprising opposing arms with a first section that contacts against opposing lateral side walls and a second section that is laterally spaced inward from the lateral side walls, the latch further comprising fingers that extend outward and engage the tray to connect the tray to the housing.

9. A light strip comprising:
a housing comprising a back wall and a pair of lateral side walls that extend outward from the back wall, the housing having a channel that extends between the lateral side walls and having a longitudinal axis;
a tray attached to the housing and positioned in the channel, the tray comprising feet that extend laterally inwardly towards a center of the channel and away from the lateral side walls;
an LED assembly mounted to the tray and comprising LED elements that emit light outward away from the tray;
an elongated lens with a central section configured to extend over the LED assembly and lateral sections on opposing sides of the central section and configured to engage with the tray, the lateral sections comprising an indent that opens outward and is sized to receive the feet of the tray to connect the lens to the housing;
inner end caps mounted to ends of the housing; and
outer end caps mounted at the ends of the housing, the outer end caps positioned outward from the inner end caps, the outer end caps being larger than the inner end caps such that the outer end caps extend across the housing, the tray, and the elongated lens.

10. The light strip of claim 9 , wherein the lens comprises a concave shape with the central section being curved and having an open side that is aligned with the LED assembly when the lateral sections are mounted to the tray.

11. The light strip of claim 9 , wherein the tray further comprises first and second wings and a central section with the wings shaped to match and be positioned against the lateral side walls of the housing with the central section extending across the channel of the housing and with the LED assembly mounted to the central section and away from the first and second wings.

12. The light strip of claim 11 , wherein the LED assembly comprises a substrate mounted to the central section of the tray and with the LED elements mounted to the substrate.

13. The light strip of claim 9 , wherein the inner end caps are light-transmissive end caps that extend over ends of the lens.

14. The light strip of claim 13 , wherein the outer end caps are opaque end caps.

15. A light strip comprising:
a housing with an elongated shape that extends along a longitudinal axis, the housing comprising a channel;
a tray attached to the housing and positioned in the channel;
an LED assembly mounted to the tray and comprising LED elements that emit light outward away from the tray;
an elongated lens with a central section configured to extend over the LED assembly;
inner end caps positioned at ends of the lens, the inner ends caps being light-transmissive; and
outer end caps positioned at ends of the housing and along the longitudinal axis of the housing outward from the inner end caps, the outer end caps being opaque.

16. The light strip of claim 15 , wherein the inner end caps are smaller than the outer end caps and extend over the ends of the lens and the outer end caps extend over the ends of the lens and the housing.

17. The light strip of claim 15 , wherein the housing further comprises end walls that extend across the channel and the inner end caps are aligned along the longitudinal axis with the end walls.

18. The light strip of claim 15 , wherein the inner end caps are positioned along the longitudinal axis inward from ends of the housing and the outer end caps abut against the ends of the housing.

19. The light strip of claim 15 , wherein the outer end caps are aligned perpendicular to a back wall of the housing.
