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 plate in communication with at least one of the light source or the frame;

a first engagement flange in communication with at least one of the plate or the frame, the first engagement flange comprising a tab insert window;

a mounting structure with a window of sufficient size to permit the light source, the frame, the plate, and the first engagement flange to pass through the window;

a seat configured to hold the light source, the frame, the plate, and the first engagement flange, 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; and

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.

2. The lighting apparatus of claim 1, further comprising a housing in communication with the plate or the frame and configured to enclose components for light source operating components, wherein the window is of sufficient size to further permit the housing to pass through the window, and wherein the seat is configured to further hold the housing.

3. The lighting component of claim 2 where one or more of the frame, plate, first engagement flange, mounting structure, seat, second engagement flange, or housing are constructed of sheet metal.

4. The lighting component of claim 3 where two or more of the frame, plate, 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 1 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, where the lens, plate, and frame cooperate to substantially enclose the light source.

10. A lighting assembly 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;

a plate in communication with at least one of the light source or the frame;

a lens in communication with the frame, where the lens, plate, and frame cooperate to substantially enclose the light source;

an engagement flange in communication with at least one of the plate or the frame, the engagement flange comprising a tab insert window; and

a housing in communication with the plate and configured to enclose light source operating components, the housing comprising a tab configured to engage the tab insert window to allow the frame to be rotated about the tab.

11. The lighting component of claim 10 where one or more of the frame, plate, engagement flange, mounting structure, seat, tab insert window, or housing are constructed of sheet metal.

12. The lighting component of claim 11 where the two or more of the frame, plate, engagement flange, mounting structure, seat, tab insert window, or housing are contiguous.

13. The lighting component of claim 10 where the one or more lighting elements comprise a light emitting diode.

14. A method of installing a lighting component, comprising:

passing a lighting component through a window, where the lighting component comprises;

a light source comprising one or more lighting elements;

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

a plate in communication with at least one of the light source or the frame;

a first engagement flange in communication with at least one of the plate or frame and comprising a first engagement mechanism;

aligning the first engagement flange with a second engagement flange being in communication with a mounting structure defining the bounds of the window and a seat, and comprising a second engagement mechanism to facilitate rotatable engagement of the first engagement mechanism with the second engagement flange;

engaging the second engagement mechanism with the first engagement mechanism; and

seating the angled surface of the lighting component onto the seat of the mounting structure.

15. The method of claim 14 wherein the first engagement mechanism is a tab insert window.

16. The method of claim 15 where the second engagement mechanism is a tab.

17. A method of disengaging a lighting component from a mounting structure comprising

pushing a second engagement mechanism, where a second engagement flange comprises the second engagement mechanism;

lifting a lighting component, the lighting component comprising;

a light source comprising one or more lighting elements;

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

a plate in communication with at least one of the light source or the frame;

a first engagement flange in communication with at least one of the plate or frame and comprising a first engagement mechanism;

rotatably disengaging the angled surface of the frame from a seat defined by the mounting structure; and

passing the lighting component through a window defined by a mounting structure comprising the second engagement flange.

18. The method of claim 17 where the second engagement mechanism is a clip.

19. The method of claim 18 where the first engagement mechanism is a lip.

20. The method of claim 17 where the method further comprises rotating the lighting component.
