(Prior Art) Indicators other than meters, such as clocks, heater controls, audio, radios, and AT transmissions, which are provided at or near an instrument panel of a vehicle such as an automobile, reduce their illumination at night. Light is often used to prevent the occupants from feeling dazzling. In other words, these lighting systems have an excessively strong illuminance at night, which may give excessive stimulus to the occupants.Therefore, dimming means for reducing the luminous intensity of the illuminating means is provided, and the external lamp system is turned on. Then, as described above, the illuminance of the display is reduced. Japanese Patent Application Laid-Open No. Sho 62-166249 discloses an example of an air-conditioning state display device in which visibility is improved by lighting the display.

(Problems to be Solved by the Invention) As described above, when the illumination means of the display is dimmed by turning on the switch of the exterior lamp system, for example, the vehicle travels between tunnels in the daytime. When doing so, there is a concern that the visibility of the display may be reduced. In other words, when the tunnel continues intermittently, the vehicle often travels with the headlamp switched on, but the dimming means operates between the tunnel regardless of whether the outside is bright. This is because the illuminance of the display has been reduced.

In the dimming circuit 4, as shown in FIG. 3, when the external lamp system switch 3 is turned on (S 11), the dimming circuit 4 diminishes the lighting means 1 based on the mode signal from the dimming adjustment circuit 7. A light command is transmitted, and the degree of dimming is adjusted. That is, if the received mode signal is a daytime mode signal (Hi) (S1
2), no dimming is performed (S13), that is, the luminous intensity of the illuminating means 1 is not reduced, and each display 11 is brought into the brightest state. This allows the occupant to clearly recognize each indicator 11 even when the brightness outside the vehicle is high, and maintains good visibility, for example, even when driving with the headlights turned on between tunnels. can do.

If the intermediate mode signal (M) has been received (S14), the intermediate dimming control is performed so that the luminous intensity of the illumination means 1 is reduced by half (S15). By this intermediate dimming control, the luminous intensity of the illuminating means 1 becomes about halfway between the daytime mode and the nighttime mode, and each display 11 is illuminated to an appropriate illuminance corresponding to the lightness outside the vehicle, which remains bright even in the dark. , Moderate visibility is obtained. Therefore, for example, even when a small lamp system switch is turned on early in the twilight or early in the morning, these excellent visibility can be obtained without excessive dazzling.
