Disclosed is a light-concentrating device using multiple optical-cables in which beams of light output from a plurality of light sources are combined into one beam of light and condensed so that a focal point is formed at a desired position, to secure necessary illumination intensity at a desired remote position from the light sources, in which a focal angle of a condenser lens is adjusted so that the device exhibits a desired illumination intensity and/or desired light distribution property at a place distant from the light sources by a desired distance, and, hence, in which the device may be widely used, for example, to light a museum, swimming pool, building outer wall or building floor or bridge, or as a lighting device for a semiconductor manufacturing process or surgical operation, etc. To this end, the light-concentrating device using the multiple optical-cables includes a body, an LED module, a plurality of multi-optical-fibers, an optical-cable adaptor, an illumination intensity optical-cable and a condenser lens adjustment unit. |
