Light emitting diode and light emitting control system using same
摘要:
A light emitting diode comprises light-emitting elements inside a cup structure and a lens part that condenses the light from these elements. Light-emitting element placed at the center along the optical axis of the lens emits an outgoing beam of light with a narrow directional angle along this optical axis, and light-emitting element placed away from the optical axis emits an outgoing beam of light in an oblique direction. The light-emitting elements are individually turned on and off in accordance with the distance of the subject to be photographed.
