Abstract

A lighting fixture includes a light housing having two housing portions transversely extended at an adjacent angle less than 180 degrees to define a front angled opening, and a reflector having two reflecting portions received in the two housing portions of the light housing respectively wherein each of the reflecting portions of the reflector has a reflecting surface formed at an inner wall of the respective housing portion of the light housing. A light source arrangement includes two light sources, which are adapted for electrically connecting to a power source, supported within the two housing portions of the light housing respectively wherein the two light sources are arranged for producing lights to reflect on the two reflecting surfaces of the reflector respectively so as to project to outside through the front angled opening of the light housing with a wide projecting angle.

Claims

1. A lighting fixture, comprising:

a light housing having two housing portions transversely extended at an adjacent angle less than 180 degrees to define a front angled opening;

a reflector having two reflecting portions received in said two housing portions of said light housing respectively wherein each of said reflecting portions of said reflector has a reflecting surface formed at an inner wall of said respective housing portion of said light housing; and

a light source arrangement comprising two light sources, which are adapted for electrically connecting to a power source, supported within said two housing portions of said light housing respectively wherein said two light sources are arranged for producing lights to reflect on said two reflecting surfaces of said reflector respectively so as to project to outside through said front angled opening of said light housing, wherein said two inner walls of said housing portions of said light housing are longitudinally extended to form a common line-edge where said two inner walls of said housing portions meet with each other so as to define said adjacent angle between said two inner walls of said housing portions of said light housing such that said two housing portions of said light housing are adapted to be communicated with each other.

2. The lighting fixture, as recited in claim 1, wherein said adjacent angle of said light housing is an obtuse angle which is an angle between 90 degrees and 180 degrees.

3. The lighting fixture, as recited in claim 2, wherein said two reflecting portions of said reflector are longitudinally extended at said adjacent angle of said light housing while the two reflecting surfaces of said reflector are integrally extended in a longitudinal direction to meet with each other at said common line-edge.

4. The lighting fixture, as recited in claim 3, wherein said reflecting surface of each of said reflecting portions of said reflector, having a predetermined curvature, is formed at said inner wall of said respective housing portion of said light housing, wherein said two light sources of said light source arrangement are supported within said two housing portions of said light housing at two focus points of said reflecting surfaces of said reflector respectively.

5. The lighting fixture, as recited in claim 4, wherein a shadowing area, which is defined between said two light sources at a non-overlapped area between two light projecting angles respectively provided by said light sources, is formed at a position within said light housing.

6. The lighting fixture, as recited in claim 5, further comprising an angled opening shelter which comprises a sheltering window shaped and sized to fittingly cover at said front angled opening of said light housing and two pivot arms integrally extended from said sheltering window to pivotally connect to said light housing in such a manner that said sheltering window is capable of pivotally folding to a closed position that said sheltering window is cover on said front angled opening of said light housing to protect said light sources therein and to an opened position that said light sources within said light housing are exposed to outside.

7. The lighting fixture, as recited in claim 6, wherein said light source arrangement further comprises two electric socket supported within said two housing portions of said light housing to hold said two light sources in position respectively, wherein said electric sockets are arranged for electrically connecting with said power source so as to electrically connect said light sources with said power source.

8. The lighting fixture, as recited in claim 5, wherein said light source arrangement further comprises two electric socket supported within said two housing portions of said light housing to hold said two light sources in position respectively, wherein said electric sockets are arranged for electrically connecting with said power source so as to electrically connect said light sources with said power source.

9. The lighting fixture, as recited in claim 4, further comprising an angled opening shelter which comprises a sheltering window shaped and sized to fittingly cover at said front angled opening of said light housing and two pivot arms integrally extended from said sheltering window to pivotally connect to said light housing in such a manner that said sheltering window is capable of pivotally folding to a closed position that said sheltering window is cover on said front angled opening of said light housing to protect said light sources therein and to an opened position that said light sources within said light housing are exposed to outside.

10. The lighting fixture, as recited in claim 4, wherein said light source arrangement further comprises two electric socket supported within said two housing portions of said light housing to hold said two light sources in position respectively, wherein said electric sockets are arranged for electrically connecting with said power source so as to electrically connect said light sources with said power source.

11. The lighting fixture, as recited in claim 3, wherein a shadowing area, which is defined between said two light sources at a non-overlapped area between two light projecting angles respectively provided by said light sources, is formed at a position within said light housing.

12. The lighting fixture, as recited in claim 3, further comprising an angled opening shelter which comprises a sheltering window shaped and sized to fittingly cover at said front angled opening of said light housing and two pivot arms integrally extended from said sheltering window to pivotally connect to said light housing in such a manner that said sheltering window is capable of pivotally folding to a closed position that said sheltering window is cover on said front angled opening of said light housing to protect said light sources therein and to an opened position that said light sources within said light housing are exposed to outside.

13.
