PURPOSE: A lighting device is provided to increase a lighting range by controlling a projection angle of the light emitted from a plurality of light emitting units. CONSTITUTION: A lighting device includes a chimney module(20), a plurality of light emitting units(21), a control device and a drive unit. The chimney module includes an upper housing, a lower housing, and a lamp socket. The plurality of light emitting units are installed in the chimney module. The plurality of light emitting units include a light emitting element(211). The light emitting element is a lamp, a light emitting plate or LED lamp. The control device is installed in both sides of the light emitting unit. The control device rotates the light emitting unit. The drive unit controls the rotation angle of the light emitting unit by interlocking with the control device. A heat emitting device(213) is installed in the light emitting unit to emit the heat from the light emitting element. |
