<p>The present invention relates to a lighting device. The purpose of the present invention is to provide a lighting device capable of easily adjusting irradiation range and irradiation angle of light by using a plurality of light emitting diode lamp units. To this end, the lighting device comprises: a holder; a plurality of rotational axes combined to be rotatable on the holder; and light emitting diode lamp units respectively combined on the rotational axes. The rotational axes are radially combined around the holder, and the light emitting diode lamp units are radially arranged around the holder. An outside dead end of the light emitting diode lamp unit rotates in a lower direction around the holder so that light is concentrated to a dimming surface, or rotates in an upper direction around the holder so that light is emitted to the dimming surface. Accordingly, irradiation range and irradiation angle of light can be easily adjusted.</p> |
