Title: Current drive-type component drive circuit
Inventor: ANDO HIROTOMO
IPC: H01L33/00
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To lessen a circuit in power consumption as a whole, when an LED is turned on. SOLUTION: When switches 1, 1, and 1 are turned on, the source terminals of the corresponding FET(field effect transistor) are shut off from their drain terminals. With this setup, a current IF generated by a constant current source 3 flows passing through the LEDs 2, 2, and 2 to enable them to emit light, respectively. At this point, only the LEDs 2, 2, and 2 are present but a part such as a resistor which wastes an electric power uselessly is not present in a flow path where a current IF flows, so that all the circuit can be lessened in power consumption. When the switches 1, 1, and 1 are turned off, the source terminals and drain terminals of FETs 4, 4, and 4 are connected electrically together. With this setup, the current IF flows through the FETs 4, 4, and 4 bypassing the LEDs 2, 2, and 2, and the LEDs 2, 2, and 2 are turned off.
