Abstract:
A device for controlling light sources in which each light source emits a light for any purpose of optical fixation, illumination and optical recording, said device comprising:light-source driving elements provided for the respective light sources, said light source being driven and emitting the light in accordance with activation of the corresponding light-source driving element; anda signal output circuit connected to said light-source driving elements and for outputting signals by which said light-source driving elements are repeatedly activated, said signals outputted from said signal output circuit having shifted phases with each other;wherein said light sources are connected to a first light-source driving element and a second light-source driving element;wherein said signal output circuit includes a signal generation circuit for generating a switching signal by which the light-source driving elements are activated, and a phase delay circuit connected to the signal generation circuit for delaying a phase of said signal;wherein said signal of said signal generation circuit is directly outputted to said first light-source driving element, and is outputted to said second light-source driving element via said phase delay circuit.
