LIGHTING DEVICE CAPABLE OF EASILY OBTAINING 360 DEGREE ANGLE BEAM-RAIDER ANGLE BY A LOW COST

摘要

PURPOSE: A lighting device is provided to obtain 360 degree beam-raider angle by a simple structure.;CONSTITUTION: A light emitting unit(130) comprises a printed circuit board(132) in which many light emitting devices(134) are installed. Heat radiating units(140) are arranged along the circumference of an outer side of the light emitting unit and spaced from each other to emit beams to different directions. The heat radiating unit(140) emits heat to outside. The heat radiating unit(140) emits heat from the light emitting unit to outside. The light emitting units(130) are arranged in the heat radiating unit to be overlapped with each other.;COPYRIGHT KIPO 2013
