Abstract

A veneer configured to be secured to a backlit button of a control device may include a plate portion. The plate portion may have one or more laser-cut indicia defined therethrough, may have laser-cut rounded corners, and may have angularly offset outer edges that may be defined during an embossing process. The laser-cut indicia may be representative of a command for controlling an electrical load. The indicia may include an alphanumeric character, an icon, or the like, may define one or more substantially zero-radius corners, and may define respective inner surfaces that are substantially perpendicular to an outer surface of the plate portion. A laser-cut alphanumeric character may have variable (e.g., continuously variable) line width. The plate portion may define a rib that suspends a floating portion of the alphanumeric character relative to an open portion. The rib may define a thickness that does not exceed 0.003 inches.

Claims (30)

1. A veneer that is configured to be secured to a control device that backlights the veneer, the veneer comprising:

a metal plate portion that includes two or more openings defined therethrough by a laser cutting process, wherein the openings cooperate to define a backlit indicia and wherein at least one of the openings has a variable width;

a filler material disposed in the two or more openings, wherein the filler material is at least one of subsurface or convex relative to a front surface of the veneer, and the filler material improves at least one of an optical performance of the backlit indicia or a readability of the backlit indicia when viewed from off angle; and

a rib that extends between the two or more openings and suspends a floating portion of the backlit indicia, wherein the floating portion is at least partially surrounded by the two or more openings.

2. The veneer of claim 1 , wherein the backlit indicia is at least one of text comprising an alphanumeric character or an icon.

3. The veneer of claim 1 , wherein the veneer is affixed to, or located adjacent to, a button of the control device, wherein the button, when actuated, is associated with a command for controlling an electrical load comprising a lighting load or a motorized window treatment load, and wherein the backlit indicia is representative of the command.

4. The veneer of claim 1 , wherein the filler material is pressed into a rear surface of the veneer.

5. The veneer of claim 1 , wherein the rib has a thickness selected to be optically difficult to perceive.

6. A control device, comprising:

a translucent carrier portion configured to be backlit by one or more light emitting diodes;

a button associated with a command communicated by the control device for controlling an external electrical load when the button is actuated;

a metal veneer disposed on the carrier portion, wherein the veneer includes at least two openings defined therethrough by a laser cutting process, wherein at least one of the openings has a variable width, and wherein the openings define a backlit indicia; and

a filler material disposed in the openings, wherein the filler material is at least one of subsurface or convex relative to a front surface of the veneer, and the filler material improves at least one of an optical performance of the backlit indicia or a readability of the backlit indicia when viewed from off angle.

7. The control device of claim 6 , wherein the control device has a plurality of buttons, each button associated with a unique command for controlling the electrical load using the control device.

8. The control device of claim 7 , wherein the control device has a plurality of backlit indicia, wherein each backlit indicia is at least one of text or an icon, each backlit indicia indicating a function of a respective button.

9. The control device of claim 6 , wherein the filler material comprises a curable acrylic adhesive.

10. The control device of claim 6 , wherein the filler material comprises a laminating film.

11. A method, comprising:

embossing a metal sheet blank to outline a veneer;

laser cutting two or more openings through the veneer to define an indicia, wherein at least one of the openings has a variable width;

laser cutting another set of openings around a portion of the outline so that the veneer is partially cut out from the blank;

placing filler material into the two or more openings that define the indicia from a rear surface of the veneer; and

attaching the veneer to a translucent carrier portion of a control device, wherein the carrier portion is configured to be backlit by one or more light emitting diodes.

12. The method of claim 11 , further comprising applying a surface finish to a front surface of the veneer.

13. The method of claim 11 , further comprising leaving a rib that extends between the two or more openings to suspend a floating portion of the indicia.

14. The method of claim 13 , wherein the rib has a thickness selected to be optically difficult to perceive.

15. The method of claim 11 , wherein the filler material is coplanar with a front surface of the veneer.

16. The method of claim 11 , wherein the filler material is at least one of subsurface or convex relative to a front surface of the veneer.

17. The method of claim 11 , wherein the filler material comprises a curable acrylic adhesive.

18. The method of claim 11 , wherein the filler material comprises a laminating film.
