(effect)
Next, the effect to metering device in the present embodiment describes.
On daytime, the extraneous light 92 that sunshine etc. are stronger is injected scale 42.This extraneous light 92 is reflected by light-reflecting components 62, and outwards penetrates by color filter 52 and scale 42.This emergent light is because of the light from color filter 52 transmissions becoming particular color.Thus, the scale 42 seen of the passenger on the car will have specific color.In addition, though also white light source 18 is opened daytime, because of extraneous light the last 92, so the scale of seeing 42 still has specific color.Thus, can allow the scale 42 of demonstration particular color more eye-catching in the architrave portion 30 of silver metal look.
Even at night, also there is more weak extraneous light to inject scale 42.But because color filter 52 disposes with scale 42 interval predetermined distances, so more weak extraneous light is difficult to arrive color filter 52.On the other hand, between color filter 52 and scale 42, be provided with the space, so the part 96 of the light source light that penetrates from white light source 18 is by color filter 52, and from scale 42 transmissions and outwards penetrate.This emergent light is because of being not white light by color filter 52.Light source 18 is configured in the position of the behind of departing from color filter 52, so most light source light is not passed through color filter 52 and the directive outside.
In addition, because of from color filter 52 at interval predetermined distances dispose light-reflecting components 62, so the part 94 of light source light reflected by light-reflecting components 62, and by outwards penetrating after color filter 52 and scale 42 transmissions.This emergent light is because of the light by color filter 52 transmissions becoming particular color.Thus, the passenger on the car will see the color mixture of white and particular color from scale 42.In addition, because of be difficult to see architrave portion 30 at night, so as long as scale 42 luminous (no matter what color) will be more eye-catching.
The part of the literal 24 of dial plate 20 has light transmission.Therefore, extraneous light and light source light are reflected by light-reflecting components 62, and form parts 40 and literal 24 part transmissions and outwards penetrate from the hyalomere 54 of filter part 50, scale.Thus, no matter daytime or night, the passenger on the car can both white literal 24.
As detailed above, metering device 10 in the present embodiment is for having the structure of color filter 52 and light-reflecting components 62, this color filter 52 is configured in the behind of scale 42 and predetermined distance at interval with it, and only makes the transmittance of particular color, and this reflection part 62 is configured in the behind of color filter 52.
Be formed with the space between color filter 52 and the scale 42, the state with white light outwards penetrates so the part of light source light is not by color filter 52.Therefore, externally more weak the and light source light of light active night, can make scale 42 be shown as white substantially.In addition, because of the major part of the extraneous light that incides scale 42 penetrates by color filter 52, so have only the light of particular color outwards to penetrate.Therefore, on the more weak and extraneous light of light source light active daytime, can make scale 42 be shown as specific color substantially.Thus, can change, thereby improve the commodity of metering device 10 according to the tone of the strong and weak scale 42 of extraneous light.
In addition, can make scale 42 be shown as particular color by day, so, also can make scale 42 more eye-catching even in the architrave portion 30 of silver metal look.
In addition, light-reflecting components 62 is configured in the behind of color filter 52 and predetermined distance at interval with it.Because of between color filter 52 and light-reflecting components 62, being formed with the space,, thereby have only the light of particular color outwards to penetrate so the part of light source light is reflected by light-reflecting components 62 and pass through color filter 52 outside transmissions.Therefore, at light source light active night, scale 42 is shown as the color mixture of white and particular color.Thus, can improve the commodity of metering device 10.
In addition, light source 18 is configured in the position of the behind of departing from color filter 52.Adopt this structure, make that the state with white light outwards penetrates by the color filter transmission for the major part of light source light.Thus, according to the tone of the strong and weak scale 42 of extraneous light big change can take place, thereby improve the commodity of metering device 10.
