Abstract
PURPOSE: To enable unlit lamps to be detected simultaneously in a lamp lighting confirming device for a plurality of lamps by connecting base of a switching element for detecting and amplifying optical spectrum to a light receiving element to indicate lit lamps when other lamps are unlit.
CONSTITUTION: When a lamp L1 to be detected is lit, only optical spectrum with blue color wave length is optically introduced into a photoconductive fiber 3a, and optical spectra with green and red color wave lengths of other lamps L2, L3 are respectively optically introduced into a relay fibers to be composed with said optical spectrum. This radiation is again divided by a prism section, and when siad optical spectrum with blue color wave length is incident upon a phototransistor Tr1 current corresponding to the intensity of the light flows through the phototransistor Tr1. At that time a switching transistor Tr2 is turned off so that a luminescent diode D1 is not lit and a indicator does not indicate the luminescence. Next, when the lamp L1 to be detected is not lit, said spectrum is not optically introduced into the photoconductive fiber 3a and the luminescent diode D1 is lit.
