Abstract:
The purpose of the present invention is to provide an illumination device that is capable of being used over prolonged periods of time while enabling the light distribution to be three-dimensionally controlled. This illumination device is characterized by including a light source part, a power supply part, and a control part; the light source part including a three-dimensional mounting substrate and a plurality of light-emitting elements disposed on the mounting substrate; wiring patterns for electrically connecting the light-emitting elements and the power supply part to each other being formed on the mounting substrate; the power supply part being able to cause a drive current for driving the light-emitting elements to be fed via the wiring patterns to the light-emitting elements; the control part including a light distribution control means; and the light distribution control means controlling the drive current for each of the wiring patterns to control the light distribution three-dimensionally.
