Abstract
The invention discloses a novel LED illuminating lamp driver adopting constant-current-source driving. An electronic transformer, a current rectifier, a filter and a constant-current-source circuit are adopted for forming the novel LED illuminating lamp driver adopting constant-current-source driving, and according to the illuminating lamp driver, 220-V alternating-current voltage can be converted into needed alternating-current voltage through the electronic transformer, and then transmitted to the current rectifier to be rectified. A filter circuit is a combined filter circuit composed of a capacitor and an inductor, and therefore ripples of direct current are small. By the utilization of the characteristic of reciprocating exchanging between idle work of the capacitor and the idle work of the inductor, the power factor of the LED illuminating lamp is increased. According to the constant-current-source circuit, a three-end voltage stabilizer and a resistor are adopted and connected to form the constant-current-source circuit, in this way, a constant current value of an LED illumination lamp is obtained, and the LED illuminating lamp saves the power and is durable.
