Abstract

PURPOSE: To enable lighting of a plurality of lamps in a lighting confirming device to be confirmed positively by connecting an amplifying switching element to a light receiving element for detecting optical spectrum to light an indicator by color.
CONSTITUTION: When a lamp L1 to be detected is lit, only optical spectrum with blue color wave length from an optical blue filber 2a is optically introduced into a photoconductive fiber 3a, and other optical spectra of lamps L2, L3 are optically introduced into a relay fiber to be composed with said optical spectrum. This radiation is divided by a triangular prism section so that, when said optical spectrum with blue color wave length is incident upon a phototransistor Tr1, current corresponding to intensity of the light flows through the phototransistor Tr1. At this time the base level of a switching transistor Tr3 is lowered not to light a luminescent diode D2 so that a indicating window (red colored) of an indicator does not indicate the luminescence. On the other hand, the base level of the switching transistor Tr2 is raised to light a luminescent diode D1 so that the indicating window (green colored) of the indicator indicates the luminescence.
