Abstract

The invention provides an outdoor illuminating apparatus which includes a housing, a heat-conducting device, a light-emitting device, and an adaptor. The housing includes a space. The heat-conducting device is disposed in the space and includes a flat portion and a touching portion. The touching portion touches the housing. The light-emitting device is disposed on the flat portion and includes at least one light-emitting chip. The adaptor is engaged to the housing and includes a passage. Therein a light-guiding member could be engaged to the passage and be sealed therewith for guiding light emitted by the light-emitting chip. The housing can be assembled with a tubular body, a first cover, and a second cover, so as to form the space sealed substantially. The tubular body can be formed in one piece and a plurality of fins can be formed thereon at the same time to enhance heat-dissipating efficiency.

Claims

1. An outdoor illuminating apparatus comprising:

a housing comprising a space;

a heat-conducting device disposed in the space and comprising a flat portion and a touching portion which touches the housing;

a light-emitting device comprising a substrate, a mount, and at least one light-emitting chip, the substrate comprising a first sunken portion and a second sunken portion communicating with the first sunken portion, the mount touching the flat portion and being joined to the second sunken portion, the at least one light-emitting chip being disposed on the mount; and

an adaptor engaged to the housing and comprising a passage, wherein light emitted by the at least one light-emitting chip passes through the passage out of the housing.

2. The outdoor illuminating apparatus of claim 1, further comprising a light-guiding member engaged to the passage and sealed therewith for guiding the light emitted by the at least one light-emitting chip.

3. The outdoor illuminating apparatus of claim 1, wherein the hosing comprises a tubular body, a first cover, and a second cover, the tubular comprises a first end and a second end, the first cover is engaged to the first end, and the second cover is engaged to the second end, so as to form the space.

4. The outdoor illuminating apparatus of claim 3, wherein the first cover is engaged to the tubular body by a seal ring.

5. The outdoor illuminating apparatus of claim 4, wherein a fillister is formed on the first cover or the tubular body, and the seal ring is disposed in the fillister.

6. The outdoor illuminating apparatus of claim 3, wherein the first cover comprises a flat plate and a hole formed on the flat plate, and the adaptor is engaged to the flat plate through the hole.

7. The outdoor illuminating apparatus of claim 6, wherein a thread is formed on the adaptor, and the adaptor is screwed into the hole by the thread.

8. The outdoor illuminating apparatus of claim 6, wherein the heat-conducting device comprises a supporting portion engaged to the first cover, and the substrate of the light-emitting device is disposed on the supporting portion.

11. The outdoor illuminating apparatus of claim 1, wherein the housing comprises a sunken portion and the touching portion of the heat-conducting device is disposed on the sunken portion.

12. The outdoor illuminating apparatus of claim 1, further comprising a press plate pressed on the heat-conducting device, the press plate pressing the heat-conducting device so that the touching portion is forced to touch the housing.

13. The outdoor illuminating apparatus of claim 1, wherein the heat-conducting device comprises a heat pipe, and the touching portion is on the heat pipe.

14. The outdoor illuminating apparatus of claim 1, wherein the heat-conducting device comprises a heat pipe, and the flat portion is at an end of the heat pipe.

15. The outdoor illuminating apparatus of claim 1, further comprising a circuit module disposed in the space and electrically connected to the light-emitting device.

16. The outdoor illuminating apparatus of claim 13, wherein the circuit module comprises a circuit board, the housing comprises a first slide, and a side of the circuit board is disposed on the slide.

17. The outdoor illuminating apparatus of claim 14, further comprising a partition plate disposed in the space to separate the space into a first sub-space and a second sub-space, wherein the heat-conducting device is disposed in the first sub-space, and the circuit board is disposed in the second sub-space.

18. The outdoor illuminating apparatus of claim 15, wherein the housing comprises a second slide and a side of the partition plate is disposed on the second slide.

19. The outdoor illuminating apparatus of claim 1, wherein the space is substantially sealed.

20. The outdoor illuminating apparatus of claim 1, wherein the housing comprises a waterproof passage and a power cord could pass through the waterproof passage to electrically power the light-emitting device.

21. The outdoor illuminating apparatus of claim 1, wherein the housing comprises a waterproof connector electrically connected to the light-emitting device, and an external power supply electrically powering the light-emitting device via the waterproof connector.

22. The outdoor illuminating apparatus of claim 1, furthering comprising a mounting bracket, wherein the housing is slidably disposed on the mounting bracket and the mounting bracket comprises a dovetail groove, the housing comprises a dovetail slider, and the dovetail slider is slidably disposed in the dovetail groove.
