    • A light emitting apparatus and a method for controlling the same are provided to increase a temperature of a light emitting unit by supplying power to the light emitting unit for predetermined preparatory time before normally driving the light emitting unit when the light emitting unit is initially driven. A power supply unit(110) supplies power to a light emitting unit(120). A switching unit(130) is connected with the light emitting unit in series. A control unit(160) controls the power supply unit to regularly maintain an electric current applied to the switching unit, to supply power of a first level to the light emitting unit for predetermined preparatory time in the case of initially driving the light emitting unit, and to supply power of a second level to the light emitting unit after the predetermined preparatory time passes.
    • 提供一种发光装置及其控制方法,以在发光单元初始被驱动时,在正常驱动发光单元之前,通过向发光单元供电预定准备时间来增加发光单元的温度。 电源单元(110)向发光单元(120)供电。 开关单元(130)与发光单元串联连接。 控制单元(160)控制电源单元以定期地保持施加到开关单元的电流,以在初始驱动发光单元的情况下向发光单元提供预定准备时间的电力, 并且在经过预定准备时间之后,向发光单元供电第二电平。
