Abstract

A lighting apparatus is shown and described. In one aspect, the lighting apparatus includes a lighting component and a mounting structure. The lighting component can include a light source, a plate, and a frame. The light source can include one or more lighting elements, such as light emitting diodes. The lighting component can be releasably secured to the mounting structure.

Claims

1. A lighting apparatus comprising:

a light source comprising one or more lighting elements;

a frame at least partially enclosing the light source, the frame defining an angled surface;

a mounting structure with a window of sufficient size to permit the frame to pass through the window; and

a seat configured to hold the light source and the frame, the seat in communication with the mounting structure and extending upwardly and outwardly at an angle to the window, wherein the angled surface of the frame is configured to rest on the seat of the mounting structure.

2. The lighting apparatus of claim 1, further comprising a first engagement flange in communication with the frame, the first engagement flange comprising a tab insert window.

3. The lighting apparatus of claim 2 further comprising a second engagement flange in communication with the seat, where the second engagement flange comprises a tab configured to engage the tab insert window of the first engagement flange such that the frame may be rotated about the tab.

4. The lighting apparatus of claim 3 where two or more of the frame, first engagement flange, mounting structure, seat, second engagement flange, or housing are contiguous.

5. The lighting apparatus of claim 1, wherein at least portions of the angled surface and the seat are in contact providing an area of surface contact less than the surface of the mounting structure exposed to free flowing air.

6. The lighting apparatus of claim 1 where the one or more lighting elements comprise a light emitting diode.

7. The lighting apparatus of claim 3 where the first engagement flange is configured to create a lip which is an extension of the frame.

8. The lighting apparatus of claim 7 where the second engagement flange comprises a clip, the clip being configured to releasably secure the lip.

9. The lighting apparatus of claim 1 further comprising a lens substantially enclosing the light source.

10. The lighting apparatus of claim 1 further comprising a plate in communication with at least one of the light source or the frame.

11. The lighting apparatus of claim 1 further comprising a housing enclosing light source operating components.

12. A lighting component comprising:

a light source comprising one or more lighting elements;

a frame at least partially enclosing the light source and having an angled surface configured to rest on a seat of a mounting structure wherein the mounting structure comprises a window of sufficient size to permit the frame to pass through the window and the seat extends upwardly and outwardly at an angle to the window configured to receive the angled surface of the frame; and

a lens in communication with the frame and substantially enclosing the light source.

13. The lighting component of claim 12 further comprising an engagement flange in communication with the frame, the engagement flange comprising a tab insert window.

14. The lighting component of claim 12 further comprising a housing enclosing light source operating components.

15. The lighting component of claim 14, the housing comprising a tab configured to engage a tab insert window to allow the frame to be rotated about the tab.

16. The lighting component of claim 12 where the one or more lighting elements comprise a light emitting diode.

17. The lighting component of claim 12 further comprising a plate in communication with the frame.
