LIGHTING DEVICE

Provided is a lighting device, and more particularly, a lighting device that prevents deterioration of light efficiency and reduces overall size. The lighting device includes a light source unit, an imaging unit which transmits incident light to form a predetermined optical pattern, a mirror unit which is disposed behind the imaging unit and reflects light to the imaging unit, and a light controlunit which reflects light generated from the light source unit to the mirror unit at a predetermined angle and pattern, wherein the imaging unit includes a plurality of lenses having the same opticalaxis and arranged along the optical axis. 本发明涉及一种照明装置，尤其涉及一种能够在防止光效率降低的同时减小整体大小的照明装置。根据本发明的实施例的照明装置包括：光源部；成像部，使入射的光透过而形成预定的光学图案；镜部，位于所述成像部的后方，使光反射，以使得光入射到所述成像部；以及光控制部，将从所述光源部发出的光以预定角度及图案反射到所述镜部，其中，所述成像部包括：多个透镜，具有相同的光轴，并沿所述光轴而布置。
