Abstract:
An illuminated control for a gas range or the like provides arcuate reflective chambers capped by diffusers to create a substantially continuous glowing circular sector indicating the status of a possibly low visibility gas flames. Line power may be used for direct drive of light emitting diodes illuminating the reflective chambers through the use of discrete series-connected voltage dropping resistors distributed to prevent heat concentration.
