PURPOSE: An LED driving device and an LED driving method are provided to reduce a flash which a user feels by reducing the intensity of light according to time. CONSTITUTION: A condenser is charged through a resistor (2). An LED is connected to the condenser in parallel. A voltage is applied to the LED. A PWM control is performed by a DC source (1). An LED driving device controls the intensity of light from the LED. [Reference numerals] (1) DC power source; (2) Resistor |
