LIGHTING DEVICE

摘要

PURPOSE: A lighting device is provided to increase the lifetime of a light emitting device by excluding a capacitor or inductor. CONSTITUTION: A lighting device includes a first rectification circuit unit(100), a light emitting unit(102), and a driving circuit unit(104). The first rectification circuit unit converts AC power to DC power. A light emitting unit is electrically connected to the first rectification circuit unit and emits light by a current from the first rectification circuit unit. The driving circuit unit is electrically connected to the light emitting unit and controls the current flowing through the light emitting unit to be constant.
