Abstract
A lamp circuit is disclosed, comprising a direct current (DC) power supplier adapted to provide a supply voltage, a driving unit coupled to the DC power supplier so as to receive the supply voltage, and a light-radiating module coupled to the driving unit and having a DC output side. The driving unit generates a constant DC current that passes through the light-radiating module such that a DC voltage to be supplied to a DC load is built at the DC output side.
