    • A light emitting element drive device includes: a light emitting section having a light emitting element; output capacitance capable of storing power supplied to the light emitting section; a driver connected between the light emitting section and a reference potential and including a switch section whose conductive state is controlled by a pulse-like lighting signal depending on magnitude of a load current and a constant current source section connected in series to the switch section; and a power supply controller being a power supply that provides drive power to the light emitting section and including a function to adjust an output current supplied to the output capacitance. The power supply controller changes the supply amount of the output current for the light emitting section from the power supply controller based on load current information that is necessary peak power of the light emitting section.
    • 发光元件驱动装置包括:具有发光元件的发光部; 能够存储提供给发光部的电力的输出电容; 连接在发光部分和参考电位之间的驱动器,包括开关部分,其开关部分的导通状态受脉冲状点亮信号的影响,该脉冲状发光信号取决于与开关部分串联连接的负载电流的大小和恒定电流源部分; 以及电源控制器,其是向所述发光部提供驱动电力并且包括调整提供给所述输出电容的输出电流的功能的电源。 电源控制器基于作为发光部的峰值功​​率的负载电流信息,从电力供给控制器变更发光部的输出电流的供给量。
