Abstract

PURPOSE: To enable to detect unlighting of two lights simultaneously in a lighting confirmation device of plural number of light by making switching element for detecting and amplifying light spectrum, only when two lights of the same function at left and right are in "ON state".
CONSTITUTION: When lighting means L1 and L1' to be detected are lighted, only the blue wavelength light spectrum of each light spectrum through blue colored light filters 2a, 2a' are introduced respectively into light conducting fibers 3a and 3a'. And each light spectrum synthesized with and introduced from other light spectrum of other lighting means to be detected through mixing apparatus 4 are emitted from the emission end of the relay fiber 5. This emission light is branched by a triangle prism, and the intensity of 2 light spectrums (2L1) is injected into a phototransistor Tr1. Then the phototransistor Tr1 acts so that collector current IC may flow in accordance with the intensity of the light spectrum, and the emitter potential is rasied by the resistance R1, and the illumination diode D1 is lighted when the potential reaches the switching level or higher, and luminously indicated in a display unit.
