PROBLEM TO BE SOLVED: To form a unit for collecting light and a unit which detects an optical signal and is formed by an electric signal, with reduced thickness.SOLUTION: An apparatus for receiving light signals includes: an optical waveguide 100 having one end 101 and another end 102; a sensor unit 200 including an infrared sensor 210 for detecting an infrared signal and outputting a corresponding electric signal, an ambient light sensor 220 for detecting ambient light and outputting a corresponding electric signal, and a light-emitting device 230; a lighttight housing 300 for blocking out external light and in which the other end and the sensor unit are installed; and a controller 400 for controlling the light-emitting device by receiving the electric signal output from at least one of the infrared sensor and the ambient light sensor. The one end of the optical waveguide is optically connected to a first lens 110 for collecting the ambient light and the infrared signal, so that the optical waveguide applies the ambient light and the infrared signal from the other end to the sensor unit. The optical waveguide collects light emitted by the light-emitting device through the other end and provides the light to the one end to show the light emitted by the light-emitting device to an outside of the apparatus through the first lens.SELECTED DRAWING: Figure 1 |
