Light emitting apparatus and control method thereof

摘要

A light emitting apparatus and a control method thereof are provided. The light emitting apparatus has a semiconductor device capable of emitting light, and the control method includes the following descriptions. A driving power of the semiconductor device is reduced to an ideal power stepwise and gradually. After every time the driving power of the semiconductor device is reduced, the semiconductor device continually emits the light by the reduced driving power within a predetermined time.
