Title: Light emitting drive circuit and remote commander having the light emission drive circuit
Inventor: AMANO TOSHIO
IPC: H04N5/00
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a drive circuit with a reduced drive power for a light emitting diode. SOLUTION: A drive control signal SD outputted from a system controller 10 is fed to a base of a transistor (TR) TR, and when the TR is conductive, a coil L stores an electromagnetic energy, and when the TR is turned off next, a counter electromotive force of the coil L lights up the light emission diodes 1a, 1b. When the counter electromotive force reaches a threshold voltage of the light emission diodes or below, the coil L and a capacitor C are resonated to control the TR so as to be turned on when a collector level of the TR is close to a zero level. Since a current limit resistor to limit the drive current of the light emission diodes is omitted and a switching loss of the TR is reduced, a remote controller with saved power can be configured.
