<p>PURPOSE:To convert the display pattern in a simple circuit conversion by generating a signal pattern from a display pattern generating circuit responding to the ON/OFF operation of verious switches, and driving an LED lamp by an LED driving circuit. CONSTITUTION:In the switch section of a driver's seat, a stop lamp switch 2a, the right side and the left side turn-signal-lamp switches 2b and 2c, and a hazzard lamp switch 2d are provided. The switch 2a is used to input directly to an LED driving circuit 5 to drive an LED lamp. The switches 2b and 2c are used to convert a flashing signal from a flashing signal generating circuit 7 to a continuous signal by voltage smoothing circuits 3a and 3b, and a display pattern is input to the LED driving circuit 5 through a display pattern generating circuit 4. In a hazzard lamp, both patterns are generated at a time by turning on the switch 2d. As a result, only by converting the combination of circuits of display pattern generating circuit 4, the display pattern can be converted into verious display patterns.</p> |
