Abstract
Official abstract text for this publication.
To provide a direction indicating apparatus that is less susceptible to a change of a power supply voltage and can reduce the difference in brightness of a direction indicating lamp using an LED element between a direction indicating operation and a hazard operation. A direction indicating apparatus includes a pulse signal generating part, a first switching element, a variable resistor circuit, a direction indicating switch, a hazard switch, first and second direction indicating lamps, a voltage detecting part and a lighting status detecting part.
First claim
Opening claim text (preview).
The invention claimed is: 1. A direction indicating apparatus, comprising: a pulse signal generating part that generates a pulse signal; a first switching element having a first end to which a power supply voltage is supplied, a control terminal to which the pulse signal is supplied and a second end at which a drive current having a magnitude responsive to an amplitude of the pulse signal is output; a variable resistor circuit that is connected to the second end of the first s…
