Abstract:
1. A light emitting diode (LED) illuminating apparatus, comprising: a controller configured for setting a predetermined luminance of the LED illuminating apparatus and creating a luminance level value according to the predetermined luminance; and an illuminating member including a processor, a transforming circuit, a regulating circuit, and an LED lamp connected in series, the processor being connected to the controller to store the luminance level value and send the luminance level value as a digital signal to the transforming circuit, the transforming circuit transforming the digital signal into an analog signal and sending the analog signal to the regulating circuit, the regulating circuit including an amplifier circuit and a thyristor connected to the amplifier circuit, the amplifier circuit amplifying the analog signal, the thyristor regulating the amplified analog signal and thereby creating an output current according to the analog signal, the output current sent to the LED lamp to provide electrical power to the LED lamp, such that the LED lamp emits light having the predetermined luminance.
