Gauge having variable display
Abstract:
A gauge which uses a prism or other type of reflector to illuminate a single graphic or icon on a dial such that only one graphic on the dial is shown during the operation of the gauge. All of the remaining graphics have a dead front appearance, and cannot be viewed, such that the gauge presents only one discrete value at a time. The dial is beneath a lens, and the prism is beneath the dial. An actuator is mounted to a PCB, and an LED is also mounted to the PCB to allow the prism to transmit light to the desired area of the dial. The dial also includes a central graphic, or icon, and the gauge is able to display different values, while the central graphic remains constantly illuminated in the center of the gauge.
