FIELD: electricity.SUBSTANCE: light-emitting-diode illumination apparatus includes a casing of power source (10), inside which a power unit is located and which has a lot of connectors on its lower surface, annular frame (20) having attachment frame (23) connected to the connectors of the power source casing, and in which power transmission line (13) is arranged for supply of electric power from the power unit, and a lot of casings of illumination units (30) connected to the lower section of the frame, in which light-emitting diodes (32) are arranged. Number and position of casings of the illumination units of the light-emitting-diode illumination apparatus can be changed for variation of light and brightness distribution.EFFECT: development of an illumination apparatus by means of which distribution and intensity of illumination can be changed at the user's option and transfer of heat emitted by the power unit to the illumination unit can be avoided.5 cl, 5 dwg |
