Abstract:
A low power-consumption luminous decorative/warning means, comprising:a DC power supply unit having positive and negative electrodes for power output;a light-emitting unit including at least one light emitting element;a control unit electrically connected to said DC power supply unit and said light-emitting unit for controlling said light emitting element of said light-emitting unit to accept power supplied by said DC power supply unit and produce flashes, said control unit including at least one signal input circuit that is induced by an input trigger signal to cause said control unit to control said light-emitting unit to start producing said flashes; andan actuating unit electrically connected to said DC power supply unit and said signal input circuit of said control unit for sending a trigger signal to said signal input circuit to cause said control unit to control said light-emitting unit to start producing said flashes, said actuating unit including at least a photo-sensitive resistor, a non-photo-sensitive resistor, and a vibration switch connected in series and in such order, two ends of said actuating unit being separately coupled with said positive and said negative electrodes of said DC power supply unit, and said signal input circuit is connected to said actuating unit at a point between said photo-sensitive resistor and said non-photo-sensitive resistor, so that said signal input circuit will receive a high or low voltage when said photo-sensitive resistor is exposed to light, and a reversed voltage in the absence of light exposure.
