Patent ID: 7723923

Claim:
An electroluminescent element driving apparatus including a power supply, a controlling IC, an electroluminescent element driving unit, an electroluminescent cell comprised of an electroluminescent element is characterized by that the power supply is connected with a charging unit which supplies power to the power supply, the power supply continually stores electric power while it supplies the power to the controlling IC and the electroluminescent element driving unit, respectively, the controlling IC supplies a flash to at least one electroluminescent element driving unit, the electroluminescent element driving unit transmits a signal having the flash to the electroluminescent cell, and the electroluminescent cell displays the signal having the flash, wherein said charging unit has exterior interface and pins, (DC+, DC−) the positive interface pin is connected to a resistor (R 1 ) which is connected to the positive electrode of a diode (D 1 ), while the negative electrode of the diode (D 1 ) is connected to the positive electrode of the power supply (BAT 1 ) and the negative interface pin is connected to the negative electrode of the power supply; and wherein between the resistor (R 1 ) and the negative interface pin (DC−) are connected with a luminescent diode (LED) and the resistor (R 2 ), between the negative electrode of the luminescent limiting resistor (R 2 ), and the negative interface pin (DC−) is connected to the negative electrode of power supply (BAT 1 ).
