摘要： 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.

摘要： A gauge has a face plate which includes indicia thereon to indicate specific values of a parameter. A laser system is disposed behind and/or in front of the face plate to project a beam onto the face plate to indicate the value of a parameter. A stepper motor moves the beam based upon the output of a sensor which monitors the parameter.

摘要： A gauge of a vehicle instrument cluster includes a dial having indicia thereon. A pointer is rotatably mounted in the instrument cluster and movable to a plurality of positions relative to the dial. A light source is disposed in the gauge and adapted to direct light in a first direction. A light diverting member is disposed adjacent to the light source and receives light from the light source. The light diverting member includes a first and a second light exit areas. The first light exit area is adapted to direct a first portion of the light generally away from the dial. The second light exit area is adapted to direct a second portion of the light generally toward the dial.
