ANGLE CONTROL DEVICE OF A LIGHTING DEVICE, CAPABLE OF CONTROLLING AN IRRADIATION ANGLE AND AN IRRADIATION DIRECTION BY AN ANGLE CONTROL UNIT

摘要

PURPOSE: An angle control device of a light device is provided to minimize damage to the crops near a road at night by controlling an irradiation angle.;CONSTITUTION: A lighting device(40) is installed on a support(30). Both ends of an angle control unit(10) are opened. One end of the angle control unit is fixed on one side of the lighting device. A plurality of spiral holes(12) are formed on an upper side and a lower side of the angle control unit. A control bolt(20) is combined with the spiral hole of the angle control unit. The control bolt fastens the support for controlling the irradiation angle of the lighting device. A rotation center unit is arranged on the angle control unit to rotate the lighting device. The rotation center is a hinge shaft(11).;COPYRIGHT KIPO 2010
