Abstract

A lighted sign or lighting fixture includes a housing that contains a series of LEDs. The housing has a pair of side walls and a series of spaced apart reinforcing members that extend between and interconnect the side walls. The reinforcing members may be formed integrally with the side walls, or may be in the form of separate members that are securely attached to the side walls. An LED mounting structure, such as a PCB, may be attached to the reinforcing members, or alternatively a separate bottom wall may be secured to the reinforcing members.

Claims

1. A lighted sign, comprising:

a plurality of sign elements that are interconnected with each other and that together form a sign, wherein at least some of the sign elements are separated from each other by open areas therebetween, and wherein one or more of the sign elements are formed by a housing having a pair of sidewalls separated by a space, wherein the sidewalls and the space therebetween cooperate to define a shape of the sign element, and wherein the housing sidewalls are connected together by a plurality of axially spaced apart reinforcing members that extend across the space between the sidewalls and that are interconnected with facing inner facing surfaces defined by the sidewalls, wherein the reinforcing members maintain the space between the sidewalls, and wherein the one or more sign elements further include a translucent diffuser configured for engagement with the sidewalls of the housing over the space between the sidewalls, and a light emitting arrangement located within the space between the side walls, configured to emit light through the diffuser.

2. The lighting arrangement of claim 1 wherein each reinforcing member defines a pair of spaced apart ends that are secured to the inner facing surfaces of the sidewalls.

3. The lighting arrangement of claim 2 wherein the reinforcing members are integrally formed with the side walls.

4. The lighting arrangement of claim 2 wherein the reinforcing members are formed separately from the side walls and are secured to the inner facing surfaces of the sidewalls.

5. The lighting arrangement of claim 1 wherein the light emitting arrangement comprises a series of spaced apart light emitting diodes (LEDs) supported by an LED support structure.

6. The lighting arrangement of claim 5 wherein the LED support structure is mounted to one or more of the reinforcing members.

7. The reinforced housing of claim 6 wherein the LED support structure is a printed circuit board.

8. The lighting arrangement of claim 1 wherein the housing further comprises a bottom wall extending between the side walls.

9. The lighting arrangement of claim 8 wherein the bottom wall is formed integrally with the side walls.

10. The lighting arrangement of claim 8 wherein the bottom wall is formed integrally with one or more reinforcing members.

11. The lighting arrangement of claim 8 wherein the bottom wall is mounted to one or more of the reinforcing members.

12. The lighting arrangement of claim 1 wherein one or more reinforcing members have a mounting structure that supports the light emitting arrangement.

13. The lighting arrangement of claim 12 wherein the mounting structure defines an aperture and wherein the light emitting arrangement is secured to each reinforcing member via at least one attachment element engaged within the aperture.

14. A lighted sign, comprising:

a plurality of sign elements that are interconnected with each other and that together form a sign, wherein at least some of the sign elements are separated from each other by open areas therebetween, and wherein one or more of the sign elements are formed by a housing having a pair of sidewalls separated by a space, wherein the sidewalls and the space therebetween cooperate to define a shape of the sign element, and wherein the housing sidewalls are connected together by a plurality of axially spaced apart reinforcing members that extend across the space between the sidewalls and that are interconnected with facing inner surfaces defined by the sidewalls, wherein the reinforcing members maintain the space between the sidewalls, and wherein the side walls and each reinforcing member cooperate to define an H-shaped cross-section, and wherein the one or more sign elements further include a translucent diffuser configured for engagement with the sidewalls of the housing over the space between the sidewalls, and a light emitting arrangement located within the space between the side walls for emitting light through the diffuser.
