Abstract

The invention features an improved lighting fixture structure with temperature control and stray light reductions, together with a unique directional pivot/extension mounting mechanism.

Claims

1. A light fixture comprising,

a glare shield,

a reflector mounted within said glare shield,

a lens mounted to said reflector, and

a socket assembly mounted to one end of said glare shield in order to permit air flow through said socket while preventing light radiation therefrom.

2. The fixture recited in claim 1 including,

lamp mounting means mounted to said socket assembly.

3. The fixture recited in claim 1 including,

said reflector and said lens are mounted to said glare shield.

4. The fixture recited in claim 3 wherein,

said reflector and said lens are integrally formed.

5. The fixture recited in claim 1 wherein,

said socket assembly is threadedly mounted to said one end of said glare shield.

6. The fixture recited in claim 1 including,

an element holder disposed at a second end of said glare shield adjacent to said lens.

7. The fixture recited in claim 6 wherein,

said element holder is selectively detachable from said glare shield.

8. The fixture recited in claim 6 including,

at least one lens louver or a filter are mounted in said element holder.

9. The fixture recited in claim 8 including,

a retention ring mounted in said element holder to retain said elements or said filter within said element holder.

10. The fixture recited in claim 6 wherein,

said element holder comprises at least one groove machined into the inner surface of said glare shield.

11. The fixture recited in claim 1 including,

an electronic ballast connected to said socket assembly.

12. The fixture recited in claim 11 including,

housing means for enclosing said electronic ballast.

13. The fixture recited in claim 12 including,

switch means mounted to said housing means for selectively deactivating said electronic ballast.

14. The fixture recited in claim 1 wherein,

said reflector comprises a precision-formed aluminum or glass unit with a reflective inner surface.

15. The light fixture recited in claim 1 wherein,

said-socket assembly comprises,

a cylinder housing,

an end cap attached to enclose one end of said housing,

at least one ventilation hole provided through said end cap,

a socket mounting plate which is slightly smaller than the interior diameter of the socket housing to allow air to pass around the perimeter of the socket mounting plate, and,

a lamp socket mounted to the socket mounting plate wherein light radiating from a lamp contained in the socket cup is shielded from the ventilation hole by said mounting plate.

16. The light fixture recited in claim 15 wherein,

said cylinder housing is die cast aluminum.

17. The light fixture recited in claim 15 including,

at least one stand-off provided on the inner surface of said end cap.

18. The fixture recited in claim 1 including,

locking means for selectively locking said socket assembly and said glare shield together.
