  • Sparkle suppression circuit to protect the contact terminals of operation light bulbs
    Patent number: 6469456
    Abstract: A sparkle suppression circuit to protect the contact terminals of operation light bulbs contains at least a power supply, a driving circuit, a sensor circuit, and a control circuit. The power supply provides the power needed for the suppression circuit. The sensor circuit detects sensor signals of the operation light bulb and to output the sensor signals. The control circuit receives and processes the sensor signals and thereby generates a driving signal to a driving circuit so as to control the switch of the operation light bulb. When the control circuit detects abnormal sensor signals, it sends out a driving signal to turn off the switch of the operation light bulb, terminating the power output.
