Abstract
This invention relates to a novel gauge lighting structure, mainly comprising the gauge panel, the lighting guide element and the lighting supply element. The gauge panel is very broadly used on the instrument cluster of the transportation vehicles. The gauge panel is an empty round housing with a glass pane mounted on the top for seeing through the signs or the record on the panel. The lighting guide element is a curve tube made of lighting sensitive material. The lighting supply element supplies the lighting from one end or two ends of the lighting guide tube. The lighting guide tube will absorb and transmit the lighting coming from the lighting supply and illuminate the inside of the gauge panel. The luminance of the lighting supply element is well controlled to regulate the sensitive lighting in the light guide tube to obtain clear signal signs and decorative blinking.
