<p><P>PROBLEM TO BE SOLVED: To provide an auto-light control device capable of adjusting the lighting timing of small lights and headlights made by the user by such a very simple constitution as volume-type adjustment. <P>SOLUTION: The auto-light control device is equipped with first comparator circuits 21 and 31 to compare the sensing value of an illuminance sensor 11a with the reference value, third delay circuits 22 and 32 whereto the outputs of the first comparator circuits 21 and 31 are connected, second comparator circuits 23 and 33 in which the outputs of the third delay circuits 22 and 32 are connected with the minus side inputs of comparators 23a and 33a and the second reference value is given to the plus side inputs, and output circuits 24 and 34 to control lighting and extinction of the lights with the outputs of the second comparator circuits 23 and 33, and it is arranged so that the small lights are lighted up at all times when the headlights are lighted by connecting the output circuits 24 and 34 with each other through a diode D1. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
