    摘要: In performing an light emitting operation using a plurality of semiconductor light-emitting devices, these semiconductor light-emitting devices are lighted up such that the driving current is lessened and the life time of the devices is prevented from being shortened and lights can be emitted to a remote site without reducing an amount of lights. Semiconductor laser devices 23a to 23c, which emit lights through independent lenses 25a to 25c, are connected in series to each other and connected to a signal generating circuit 24, serving as a power supply, so as to perform pulse lighting, whereby making it possible to light up three semiconductor laser devices simultaneously at a driving current corresponding to one semiconductor laser device. A package of semiconductor laser devices 23a to 23c comprises three lead terminals, and an electrical connection to two lead terminals, which are electrically insulated from a metallic base, is established. If a light collection point P is positioned in the midway of the detection distance range, the shifting quantity of the laser beams is minimized over substantially the entire area so that the amount of lights can be suppressed.
