Abstract
PURPOSE: To perform the immediate illumination at the time of lighting and ensure the exact and given periodical winkering of head lamp by continuously flowing current even during the winkering period.
CONSTITUTION: When operating switches 6 and 6', a current is supplied to a flip- flop circuit 7, a given periodical oscillation is generated, a transistor Tr1 is kept under ON-OFF control, and a transistor Tr0 operates in ON or OFF state correspondingly. In a filament Fh, a current enough to make it a winkering state apparently flows through a resistance R0 even during the period when the transistor Tr0 is OFF, and when the transistor Tr0 turns ON, the filament Fh begins to luminesce immediately. Thus, the responsiveness to the luminance of filament becomes better, so that the periodicity of luminescence is made exact.
