ABSTRACT:
A first ohmic electrode of a light emitting diode is put into contact with an electrode plate, and a second ohmic electrode of the same is put into contact with a mesh electrode formed by a metal net. The mesh electrode is mounted on a light receiving surface of the light receiving element. When a predetermined amount of current is supplied from a power source to the mesh electrode and electrode plate, light is emitted from that portion of the light emitting diode located around the second ohmic electrode, and the light passes through the spaces of the mesh electrode, then being received by the light receiving element. The light receiving element supplies an electric signal indicative of the light to a measuring circuit, whereby the output of the light emitting diode is measured.
