 Led light with triac-ballasted patent thumbnailLed light with triac-ballasted
A led light with triac ballasted contains a thermistor, ceramic capacitors, resistors, diac, triac, bridge rectifiers, and led lights, such that after a power supply is conducted, a heat and an impedance of the thermistor change, and then a rc charging/discharging time changes to forward or to lag a phase of the diac for triggering the triac, thus lowering the power to stabilize led brightness or to ballast the led lights. Since the triac-ballasted led light is simplified, i.e., electrolytic capacitors, transformers, inductors and chips are eliminated, so a failure rate is much lower than conventional switch-mode drive led lights.
