A method and
system are provided to illuminate an indicator, including indicators for
electronic systems, appliances, and motor vehicle settings such as a visible temperature setting. Lighting efficiency is maximized, while light leaks, bright spots, shadows, internal reflections, color bleeds, and other undesirable visual effects are avoided. A lightbox having a cavity contains emitted light and transmits the light to an indicator. The indicator displays a
system setting and an
encoder varies the
system setting. In an aspect, a light block and ramp are formed in the lightbox to uniformly dispense light to the indicator. A light dividing
ridge formed in the lightbox separates the light dispensed to separate sections of the indicator. Further improvements include a tight fit formed between the indicator and a control knob, and a maximized indicator base area adjacent to the lightbox. The lightbox can also be integrated as part of a switchpad, reducing costs.
