Abstract

PURPOSE:To avoid the delay of turning on lights when entering a tunnel by arranging so that the lights can be also turned on manually under a condition that a transfer switch is turned to the ''automatic'' side and the lights are to be turned on and off by detection of the outside illuminance. CONSTITUTION:When a one-touch switch 28 is closed immediately before entering a tunnel under a condition that a transfer switch 13 is turned to the ''automatic'' side, the output of a one-touch light circuit 26 is made H, and transistors 7-9 are turned on to turn on head lights 4 and small lights 6 and a transistor 33 is turned on to turn on a monitor light 6. Next, after entering the tunnel, outputs of the second and first discriminating circuits 5, 2 in succession and a backup circuit 3 are made H, thus keeping the transistors 7-9, 33 on and resetting the lighting circuit 26. After leaving the tunnel, the transistors 7-9 are turned off, putting out the lights. Accordingly, the delay of turning on the lights can be avoided and the driver can be reliably protected from forgetting to put out the lights.

When the one-touch switch 28t' is closed just before the tunnel, i.e., at point 1g4, t'', the closed signal tube receives the I-1ffi circuit (26-set-like Mt: ), and the one IWf.
At the same time as the signal 28 indicates that it is closed, the output signal of the one point f11I circuit 26 becomes high level. This output signal makes the transistor 12 conductive and applies the applied voltage Vaeit#l to each of the terminals JCJ7 to JCJ9 and simultaneously supplies it to the base of the transistor 55. For this reason, Tonjisu p7'~9'# conducts and as described (Headlight 4 and Small Quitto turn on □ and sympathetic Nitotsunjisume 35 conduct, and Moe I-Quito 57 turns on, and the headlight turns on. The light and the small quill turn on to indicate that the light is on.

On the other hand, when the output signal of the discrimination circuit 5 of aI2 reaches a high level 6, 156 becomes conductive via this output signal tmj2, and as a result, the transistor 155 also becomes conductive.

Therefore, the transistor 54 becomes non-conducting, and the resistor 5 in parallel with the scissors 57 is inserted into the circuit C;

Exit of the tunnel C: i: The outside of the car is next - C: As it gets brighter, the outside illuminance i changes according to this rate.
In the 61st period, the power signal changed, and the 'Tai 5 figure was set to α: at -i.
When the discrimination diagram 1132 of 1 and the output signal of the back step circuit S change to low level ε;, the transistors 7-8 become non-conducting yim (2), and the headlight 4 disappears.
Then, at the point where the outside of the vehicle becomes even bigger, the output signal of the second discrimination diagram 145 changes to a level of 9, and the transition 9.55 becomes non-conducting. Small late 6 and monitor 2 light 57 are lit at o,
