Abstract

A door for an outdoor lighting fixture can include a base portion and a cantilever portion. The base portion can include a first light source receiving area and at least one attachment recess, where the first light source receiving area is disposed on a bottom of the base portion. The cantilever portion can be disposed at a distal end of the base portion and can include a second light source receiving area disposed on a bottom side of the cantilever portion. The at least one attachment recess can be configured to receive a securing clip of a cabinet of the outdoor lighting fixture. The first light source receiving area can be configured to receive a first light source, and the second light source receiving area can be configured to receive a second light source.

Claims

1. A door for an outdoor lighting fixture, the door comprising:

a base portion comprising a first light source receiving area and at least one attachment recess and having a length substantially equal to a length of a cabinet of the outdoor lighting fixture, wherein the first light source receiving area is disposed on a bottom of the base portion; and

a cantilever portion disposed at a distal end of the base portion and comprising a second light source receiving area disposed on a bottom side of the cantilever portion,

wherein the at least one attachment recess is configured to receive at least one securing clip of the cabinet of the outdoor lighting fixture,

wherein the first light source receiving area is configured to receive a first light source,

wherein the second light source receiving area is configured to receive a second light source,

wherein the cantilever portion extends beyond the cabinet away from the distal end of the base portion,

wherein the first light source receiving area is adjacent to the second light source receiving area, and

wherein the base portion and the cantilever portion are configured to open away from the cabinet when the at least one securing clip is decoupled from the at least one attachment recess.

2. The door of claim 1, wherein the first light source is positioned toward the distal end of the base portion.

3. The door of claim 1, wherein the base portion and the cantilever portion are formed from a single piece.

4. The door of claim 3, wherein the base portion and the cantilever portion are formed without an extrusion.

5. The door of claim 1, wherein the cantilever portion further comprises:

a third light source receiving area disposed on the bottom side of the cantilever portion, wherein the second light source receiving area and the third light source receiving area are laid out in series along a length of the cantilever portion, wherein the third light source receiving area is disposed at a distal end of the cantilever portion.

6. The door of claim 1, wherein the cantilever portion further comprises:

a wireway disposed on a top of the cantilever portion, wherein the wireway is disposed between a proximal edge of the cantilever portion and a top end of a third light source receiving area, wherein the wireway is further disposed across a top end of the second light source receiving area, and wherein the wireway forms a cavity through which a power transfer device can be disposed.

7. The door of claim 1, wherein the cantilever portion further comprises:

a heat sink assembly comprising a plurality of heat-conducting fins and disposed on a top of the cantilever portion; and

at least one vent disposed between the heat sink assembly and the second light source receiving area.

8. The door of claim 7, wherein the at least one vent traverses the cantilever portion adjacent to the second light source receiving area and a first heat-conducting fin of the plurality of heat-conducting fins.

9. The door of claim 8, wherein the first heat-conducting fin forms an outer edge along a length of the cantilever portion, wherein the first heat-conducting fin has a height that is substantially the same as a height of the cabinet of the outdoor lighting fixture.

10. The door of claim 9, wherein a second heat-conducting fin of the plurality of heat-conducting fins is thermally coupled to the first heat-conducting fin and a top end of the second light source receiving area.

11. The door of claim 1, wherein the cantilever portion further comprises:

a wireway disposed on a top of the cantilever portion, wherein the wireway is disposed between a proximal edge of the cantilever portion and a top end of the second light source receiving area, and wherein the wireway forms a cavity through which a power transfer device can be disposed.

12. An outdoor lighting system, comprising:

a mounting pole;

a cabinet mechanically coupled to the mounting pole, wherein the cabinet has a length and comprises at least one securing clip;

a door mechanically coupled to the cabinet, wherein the door comprises;

a base portion having substantially the length and comprising a first light source receiving area and at least one attachment recess, wherein the first light source receiving area is disposed on a bottom of the base portion, and wherein the at least one attachment recess receives the at least one securing clip to mechanically couple the base portion to the cabinet; and

a cantilever portion disposed at a distal end of the base portion and comprising a second light source receiving area disposed on a bottom side of the cantilever portion, wherein the cantilever portion extends beyond the cabinet away from the distal end of the base portion;

a first light source disposed within the first light source receiving area of the base portion; and

a second light source disposed within the second light source receiving area of the cantilever portion,

wherein the door opens away from the cabinet when the at least one securing clip is decoupled from the at least one attachment recess, and

wherein the first light source is adjacent to the second light source.

13. The outdoor lighting system of claim 12, further comprising:

a power source electrically coupled to the first light source and the second light source, wherein the power source is disposed in the door.

14. The outdoor lighting system of claim 12, wherein the base portion comprises a first attachment feature disposed at a proximal end of the base portion, wherein the cabinet comprises a second attachment feature disposed at a proximal end of the cabinet, and wherein the first attachment feature hingedly couples to the second attachment feature.

15. The outdoor lighting system of claim 12, wherein the first light source comprises at least one light-emitting diode (LED) and an optical device that covers the at least one LED.

16. The outdoor lighting system of claim 15, wherein the first light source, when disposed in the first light source receiving area, is substantially planar with the bottom of the base portion.

17. The outdoor lighting system of claim 12, wherein the cantilever portion further comprises:

a heat sink assembly comprising a plurality of heat-conducting fins and disposed on a top of the cantilever portion; and

at least one vent disposed between the heat sink assembly and the second light source receiving area.

18. The outdoor lighting system of claim 17, wherein the at least one vent traverses the cantilever portion adjacent to the second light source receiving area and a first heat-conducting fin of the plurality of heat-conducting fins.

19. The outdoor lighting system of claim 18, wherein the cabinet and the cantilever portion of the door each comprise a top surface that directs moisture to flow toward the at least one vent.

20. The outdoor lighting system of claim 17, wherein the plurality of heat-conducting fins is made without extrusion.
