Light emitting apparatus

A light emitting apparatus, comprising:

• a visible light emitter for emitting visible light;
• an invisible light emitter for emitting invisible light;
• an invisible light receiver for receiving invisible light emitted from the invisible light emitter;
• a cover member arranged spaced apart from the visible light emitter, the invisible light emitter, and the invisible light receiver and covering the visible light emitter, the invisible light emitter, and the invisible light receiver;
• and
• a controller for controlling operation of the visible light emitter, wherein
• the cover member has flexibility so as to deform when receiving external force, and at least partially reflects invisible light emitted from the invisible light emitter and passes and diffuses visible light emitted from the visible light emitter,
• the invisible light emitter emits invisible light toward an inside surface of the cover member, and the invisible light receiver receives invisible light emitted from the invisible light emitter and reflected by the cover member,
• the controller controls a mode of emission of visible light emitted from the visible light emitter in accordance with a state of reception of invisible light at the invisible light receiver, which changes in accordance with deformation of the cover member.
