摘要： The reflective collection-type light receiving unit of the present invention is a reflective collection-type light receiving unit having a light receiving element which receives spatial light on which an information signal is superimposed after being reflected and collected via a concave mirror. The light receiving element is arranged approximately at the center inside the concave mirror, with the light receiving plane thereof facing to the reflection plane of the concave mirror. A pair of electrode leads connected to both electrodes of the light receiving element are extended so as to be opened from the center on the front plane of the concave mirror to both sides and connected to a light receiving circuit by way of the lateral plane of the concave mirror.

摘要： A visible light communication apparatus is constituted with a transmitter for illuminating and projecting visible light on which an information signal is superimposed from a lamp fitting and a receiver for receiving the visible light to take out the information signal superimposed on the visible light. The transmitter modulates a transmission information signal, driving a light projecting element of the lamp fitting so as to superimpose the transmission information signal on the visible light of the lamp fitting, thereby radiating white light containing a blue light component as visible illumination light. The receiver receives the white visible light containing the blue light component radiated from the transmitter and generates a receiving information signal from the light receiving signal on a receiving circuit. A blue light photodiode which receives blue light at the highest sensitivity to output a light receiving signal is used as a light receiving element of the light receiving unit. The lamp fitting for radiating the white light containing the blue light component on the side of the transmitter as visible illumination light and the blue light photodiode for receiving blue light on the side of the receiver at the highest sensitivity can be used to perform visible light communications at high speed, while illuminating by the white light.
