ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to meters, and particularly to a meter for a vehicle.
2. Related Art
A conventional meter for a vehicle has a circular dial and a ring member attached to the dial to surround the dial. A surface of the ring member is painted with silver paint. However, the meter may look ordinary and uniform.
SUMMARY OF THE INVENTION
In view of the foregoing problems, it is an object of the present invention to provide a meter which looks novel and original.
According to the present invention, a meter has a dial, a ring member having an annular light transmitting member disposed along a periphery of the dial and a first colored layer having a first color and disposed on an inner side face and an outer side face of the light transmitting member, a light source disposed at a rear side of the ring member for emitting light and a second colored layer having a second color and disposed between the light source and the ring member. The light transmitting member has a light emitting portion for emitting light toward a front side.
When the light source is turned on, the light source emits light toward the second colored layer. Light enters the second colored layer, and the second colored layer emits light of the second color toward the ring member. Then, light of the second color enters the ring member and is emitted from the light emitting portion. As a result, the light emitting portion of the ring member is illuminated by light of the second color and appears the second color. When the light source is turned off, the first colored layer becomes visible through the light emitting portion, and the light emitting portion appears the first color. Therefore, the meter looks novel and original due to the ring member.
