Abstract
The present invention relates to a hybrid constant current LED lamp. The LED lamp includes a rectifier unit, a filter circuit, a switching mode power supply, at least one main LED and a subsidiary LED. The main LED is electrically connected in series to the output terminal of the rectifier unit and the input port of the primary-side circuit of the switching mode power supply. The subsidiary LED is connected to the secondary-side circuit. The invention not only provides circuit architecture capable of providing a constant current, but also improves the power efficiency of the lamp.
