Abstract

A water resistant LED light fixture having a fixture body with a water tight wire sealing compartment and a mounting mechanism for mounting the light fixture and enabling it to be positioned at various selected angles to facilitate aiming of the illumination provided by the fixture.

Claims

1. Light fixture apparatus comprising:

a fixture body;

a light transmissive cover removably attachable to the fixture body;

one or more LEDs located within the fixture body and positioned to direct light through the light transmissive cover;

a wire sealing compartment located on an underside of the fixture body and defining an open interior space configured to receive first and second electrical leads; and

first and second gaskets positioned within an interior of the wire sealing compartment and configured to pass and sealingly engage said first and second electrical leads.

2. The light fixture apparatus of claim 1 further comprising a snap-in cover which compresses the first and second gaskets and closes a bottom opening of the wire sealing compartment.

3. The light fixture apparatus of claim 2 further comprising a cover lock configured to lock the snap-in cover in place.

4. The light fixture apparatus of claim 1 wherein the wire sealing compartment comprises respective parallel vertical interior sidewalls with an orthogonally disposed vertical entry wall joining the parallel sides at first ends thereof and an orthogonally disposed exit wall joining the parallel sides at second ends thereof and wherein the exit and entry walls have respective entry and exit openings formed therein, the entry opening including a pair of wire entry grooves shaped to receive said first and second electrical leads, the exit opening including a pair of wire exit grooves shaped to receive said first and second electrical leads.

5. The light fixture apparatus of claim 4 wherein the exit and entry openings are identically shaped.

6. The light fixture apparatus of claim 5 wherein the exit and entry openings each have parallel vertical side edges.

7. The light fixture apparatus of claim 6 wherein the vertical sidewalls and exit and entry sidewalls meet at respective rounded corners.

8. The light fixture apparatus of claim 4 further comprising first and second vertical ribs respectively spaced apart from, and running parallel to, each of the vertical interior sidewalls, the vertical ribs defining respective channels into which each of the first and second gaskets fit.

9. The light fixture apparatus of claim 8 wherein the first and second vertical ribs further include a portion spaced apart from and running parallel to the entry and exit walls and forming respective first and second openings through which said first and second leads pass.

10. The light fixture apparatus of claim 9 wherein the shape of the first and second openings conforms to the shape of the entry and exit openings in the entry and exit walls.

11. The light fixture apparatus of claim 8 further including a centrally positioned vertical wire guide on a floor of the wire sealing box which serves to separate and guide the respective electrical leads.

12. The light fixture apparatus of claim 1 wherein the one or more LEDs are mounted on a printed circuit board positioned within the fixture body and further comprising a cover mounted over the one or more LEDs and having a plurality of apertures, each aperture being positioned over a respective one of the one or more LEDs.

13. The light fixture apparatus of claim 12 wherein each of the plurality of apertures is shaped to alter the light distribution pattern of the light fixture apparatus.

14. The light fixture apparatus of claim 1 further comprising:

a receptacle shaped to receive and hold the fixture body and its wire sealing compartment; and

a turret mechanism configured to pivotally mount the receptacle, the turret mechanism comprising;

a cradle component having a semicircular exterior surface and having a plurality of ratchet teeth located in first and second semicircular channels positioned on respective sides thereof

a bracket component configured to receive and hold the receptacle, the bracket component having a semicircular interior surface shaped to pivotally mate with the semicircular exterior surface of the cradle component; and

a spring component attached to said bracket component and configured to engage said ratchet teeth so as to enable the bracket component to be pivoted to a selected angle with respect to the cradle component and fixed in position at that angle.

15. The light fixture apparatus of claim 3 wherein the light transmissive cover snaps on to the fixture body, wherein the snap-in cover snaps into the wire sealing compartment, and wherein the cover lock resiliently engages the snap-in cover.

16. The light fixture apparatus of claim 1 wherein the wire sealing compartment is box-shaped.

17. Light fixture apparatus comprising:

a fixture body;

a light transmissive cover removably attachable to the fixture body;

one or more LEDs located within the fixture body and positioned to direct light through the light transmissive cover;

a wire sealing compartment formed as a unitary part of the fixture body and located on an underside thereof, the wire sealing compartment defining an open interior space configured to receive first and second electrical leads;

first and second gaskets installed in an interior of the wire sealing compartment and sealingly engaging said first and second electrical leads in watertight fashion.

18. The light fixture apparatus of claim 17 further comprising a snap-in cover which compresses the first and second gaskets and closes a bottom opening of the wire sealing compartment.

19. The light fixture apparatus of claim 18 further comprising a cover lock configured to lock the snap-in cover in place.

20. The light fixture apparatus of claim 17 wherein the wire sealing compartment comprises respective parallel vertical interior sidewalls with an orthogonally disposed vertical entry wall joining the parallel sides at first ends thereof and an orthogonally disposed exit wall joining the parallel sides at second ends thereof and wherein the exit and entry walls have respective entry and exit openings formed therein, the entry opening including a pair of wire entry grooves shaped to receive said first and second electrical leads, the exit opening including a pair of wire exit grooves shaped to receive said first and second electrical leads.

21. The light fixture apparatus of claim 20 wherein the exit and entry openings are identically shaped.

22. The light fixture apparatus of claim 21 wherein the exit and entry openings each have parallel vertical side edges.

23. The light fixture apparatus of claim 22 wherein the vertical sidewalls and exit and entry sidewalls meet at respective rounded corners.

24. The light fixture apparatus of claim 20 further comprising first and second vertical ribs respectively spaced apart from, and running parallel to, each of the vertical interior sidewalls, the vertical ribs defining respective channels into which each of the first and second gaskets fit.

25. The light fixture apparatus of claim 24 wherein the first and second vertical ribs further include a portion spaced apart from and running parallel to the entry and exit walls and forming respective first and second openings through which said first and second leads pass.

26. The light fixture apparatus of claim 25 wherein the shape of the first and second openings conforms to the shape of the entry and exit openings in the entry and exit walls.

27. The light fixture apparatus of claim 25 further including a centrally positioned vertical wire guide on a floor of the wire sealing box which serves to separate and guide the respective electrical leads.

28. The light fixture apparatus of claim 17 wherein the one or more LEDs are mounted on a printed circuit board positioned within the fixture body and further comprising a cover mounted over the one or more LEDs and having a plurality of apertures, each aperture being positioned over a respective one of the one or more LEDs.
