Abstract:
A gauge may employ a dial plate, a pointer shaft driven by a motor, a printed circuit board having a plurality of light sources, such as LEDs, and a motor. An upper pointer may be located on a viewed side of the dial plate and a lower pointer may be located on an unviewed side of the dial plate. The upper and lower pointers are attached to the pointer shaft. The lower pointer is positioned to receive light from the light source and direct the light into indicia and graduations of the dial plate, and into the upper pointer. An area surrounding the upper pointer is more brightly lit than other areas of the dial plate. A light-collecting ring may collect light and transmit light into the lower pointer. The ring may be an integral or attached part of the lower pointer or it may be a detached and separate piece.
