Abstract
The present invention relates to a lighting apparatus which stably performs dimming control on a lamp implemented with light emitting diodes (LEDs) or the like. The lighting apparatus may improve power efficiency by driving power supplied to a lamp in a current regulation method, perform constant current control such that the lamp maintains constant brightness, perform dimming control for controlling the brightness of the lamp, commonly supply the power provided to the lamp to peripheral circuit modules, and perform constant voltage control such that a driving voltage supplied as power is maintained at a predetermined level or more.
