Abstract: A flash unit capable of being attached to a flash control unit, comprising: a memory that stores information relating to a light emission time for actual flash corresponding to a difference between an emitted light amount command value for actual flash and an emitted light amount command value for pre-flash, and a controller, including an light emission time calculation section that obtains light emission time corresponding to emitted light amount command value for actual flash based on emitted light amount command value for pre-flash, emitted light amount command value for actual flash, and information stored in the memory, wherein the controller inputs the emitted light amount command value for pre-flash and the emitted light amount command value for actual flash acquired to the light emission time calculation section, and controls actual flash of the flash light emitting source based on the light emission time.

Abstract: The LED module comprises a flexible wiring substrate and surface mounting type LED packages. The flexible wiring substrate is formed at its surface with power supply terminals which comprises a first electrode pad and a second electrode pad, and is formed with a patterned wiring being electrically connected to the patterned wiring. The surface mounting type LED package comprises an LED chip and a mounting substrate. The mounting substrate is formed at its front surface with a recess, and its rear surface with a first connection electrode and the second connection electrode which are electrically connected to the first electrode pad and the second electrode pad, respectively when the mounting substrate is mounted on the flexible wiring substrate. The LED chip is disposed within the recess so as to receive the electrical current through the outside connection electrode and the power supply terminal.
