Abstract

A rear trim ring for a vandal resistant luminaire having a round front and rear opening, the rear opening mounts flush to the surface onto which the luminaire is installed eliminating pry points between the luminaire and mounting surface, and an annular space between the rear trim ring and a luminaire housing provides room for the rear trim ring to deform upon the application of physical shock absorbing a portion of the shock applied thereto.

Claims

1. A vandal resistant luminaire having a rear trim ring, said rear trim ring surrounding an outer rear portion of an electrical component housing of said luminaire, said rear trim ring being constructed to absorb physical shock to protect said vandal resistant luminaire from said physical shock, said rear trim ring having a substantially circular side wall spaced from said housing, a substantially flat rear mating edge, and a front surface about a front opening suitable for mounting substantially flush with an outwardly extending rim on said electrical component housing, thereby substantially eliminating pry points between said electrical component housing and a surface to which it is mounted, and substantially eliminating hold points about a rear portion of said luminaire.

2. The vandal resistant luminaire of claim 1 wherein said side wall has a rear opening with a larger radius than said front opening forming an annular space between the inner surface of said rear trim ring and said electrical component housing.

3. The vandal resistant luminaire of claim 2 wherein said annular space is filled with a shock absorbing material.

4. The vandal resistant luminaire of claim 3 wherein said annular space is filled with a foam material.

5. The vandal resistant luminaire of claim 3 wherein said annular space is filled with neoprene.

6. The vandal resistant luminaire of claim 1 wherein said side wall of said rear trim ring has shock absorbing ribs axially extending from the inner surface thereof.

7. The vandal resistant luminaire of claim 1 wherein said side wall has electrical component housing contact projections axially extending from the inner surface thereof proximate said front opening.

8. The vandal resistant luminaire of claim 1 wherein said side wall has an inwardly extending flange adjacent said front opening.

9. The vandal resistant luminaire of claim 8 wherein said inwardly extending flange has indentations on a top surface thereof substantially equidistantly spaced about said flange.

10. The vandal resistant luminaire of claim 9 wherein each of said indentations have an adhesive strip applied therein, said adhesive strips having front and rear adhesive surfaces.

11. The vandal resistant luminaire of claim 1 wherein said side wall has housing mating extensions extending from said side wall adjacent said front opening.

12. A vandal resistant luminaire comprising:

an electrical component housing having at least one lamp socket and associated wiring contained therein, said electrical component housing having a substantially circular side wall with an outwardly extending rim delineating a front and rear portion of said electrical component housing and a substantially disk shaped rear wall; and

a rear trim ring surrounding said rear portion of said electrical component housing, said rear trim ring having a rear opening substantially within the plane of said disk shaped rear wall of said electrical component housing, said rear trim ring having a front opening substantially adjacent said outwardly extending rim, said rear trim ring having a side wall of a larger radius than said side wall of said electrical component housing forming a void between a substantial portion of said rear portion of said electrical component housing and said rear trim ring, said rear trim ring being of a material which will deform when a physical shock is exerted thereon thereby absorbing a portion of said physical shock.

13. The vandal resistant luminaire of claim 12 wherein said void is filled with a shock absorbing material.

14. The vandal resistant luminaire of claim 12 wherein said void is filled with a high density foam material.

15. The vandal resistant luminaire of claim 12 wherein said void is filled with neoprene.

16. The vandal resistant luminaire of claim 12 wherein said side wall of said rear trim ring has axially aligned shock absorbing ribs extending from an inner surface thereof.

17. The vandal resistant luminaire of claim 12 wherein said side wall of said rear trim ring has a series of electrical component housing mating projections substantially equidistantly spaced about the circumference of and axially extending inwardly from said side wall proximate said front opening.

18. The vandal resistant luminaire of claim 12 wherein said side wall of said rear trim ring has a series of housing mating extensions axially extending from and substantially equidistantly spaced about an inwardly extending flange surrounding said front opening.

19. The vandal resistant luminaire of claim 12 wherein said side wall of said rear trim ring has shock absorbing ribs extending from an inner surface thereof axially aligned and substantially equidistantly spaced about the inner circumference thereof, a series of electrical component housing mating projections extending inwardly from said shock absorbing ribs, and a series of housing mating extensions axially extending from an inwardly extending flange surrounding said front opening.

20. A rear trim ring for a vandal resistant luminaire having a round opening with a first diameter at one end and a round opening with a second diameter at the other end, said first diameter being less than said second diameter, a flange extending inwardly proximate said opening of a first diameter, shock absorbing ribs extending inwardly, axially aligned, and equidistantly spaced about an inner surface of said rear trim ring, and housing mating extensions extending inwardly and equidistantly spaced about an inner surface of said rear trim ring proximate said opening of a first diameter.
