Moving pointer with edgewise EL lamp
First Claim
1. A gauge including a dial and a movable pointer positioned adjacent the dial, wherein said pointer comprises:
- an elongated, translucent substrate having a first side, a second side, and a front side, wherein said front side faces away from said dial;
a first EL lamp attached to said first side, said first EL lamp emitting light into said substrate from said first side and said light emanating from said front side;
said substrate including a first end and a second end, wherein said first end includes a pivot about which said pointer can rotate in a plane substantially perpendicular to said first side.

Abstract
A movable pointer includes an elongated, translucent substrate having an EL lamp covering one side of the substrate. The pointer emits light from an adjoining, narrower, front side which is roughened slightly. The ends of the substrate are capped or coated to prevent light emission. A second EL lamp can be attached to a second side of the substrate. The width of the EL lamp can be tapered to provide a pointer which is brighter at one end than at the other. Electrical connection to the EL lamp is made with a compliant ribbon having conductive stripes on one or both sides thereof. The ribbon is mechanically and electrically attached to contacts on the EL lamp.
