Document Type and Number:
WIPO Patent Application WO/2016/137232
Kind Code:
A1
Abstract:
The present invention relates to a multidirectional multifocal optical lighting device for adjusting various focal distances and forming a plurality of lighting points by configuring various combination forms of units, and the present invention comprises: a fixed body having a light source and all machine components loaded inside, having a guiding space formed on the front end thereof while recessed on the inner side thereof, and having an adjusting screw portion formed on the outer circumference of the guiding space; an adjusting piece screw-coupled to the adjusting screw portion of the guiding space, and capable of moving, by rotation, forward and backward on the front end of the fixed body; and a plurality of coupling lens units coupled to the front of the adjusting piece by screw coupling, and including coupling lenses therein, wherein the front end of the fixed body comprises a fixed light-emitting unit having, therein, a closed space in which a light-emitting unit and a fixed lens supported by a support on the front of the light-emitting unit are loaded, and the present invention comprises a branch module having a beam splitter loaded therein, so as to branch an irradiated light source through the beam splitter such that the light source is split and irradiated in a plurality of directions, and further comprises a reflection module provided on the front of a through-hole. According to the present invention, lens modules having various focal adjusting distances can be used by being combined into various combinations according to a user's selection, and thus the optical lighting device can be used according to various purposes of use and environments.
