Abstract
PURPOSE:To improve the recognition performance and safety by turning-on the first luminous part when a brake pedal is stepped on and turning-on the second luminous part which carries out the bar graph display according to the stepping-on quantity of the brake pedal. CONSTITUTION:A stop lamp 10 is equipped with a brake switch 12 which is closed by the stepping-on of a brake pedal 11 and a sensor 13 for detecting the stepping-on quantity. Further, an LED array 14 as the first luminous part which is turned-on by the closure of the brake switch 12 is installed. Further, an LED array 16 as the second luminous part which carries out the bar graph display through a bar graph display driving means 15 having an A/D conversion circuit built in, according to the stepping-on quantity of the brake pedal 11 which is detected by the sensor 13 when the brake switch 12 is closed is installed. Therefore, the luminous parts 14 and 16 are selectively turned-on according to the magnitude of the stepping-on quantity of the brake pedal 11. Further, the sensor 13 can be assembled in simple ways by constituting the sensor 13 from a magnet and an electricity/magnetism conversion element.
