Title:
LED SHADOWLESS LAMP USING CURVED-SURFACE HEAT-RADIATING PLATES
Document Type and Number:
WIPO Patent Application WO/2012/014187
Kind Code:
A1
Abstract:
The present invention relates to an LED shadowless lamp whereby it is possible to precisely control the angle of irradiation and the area of irradiation by using curved-surface heat-radiating plates and it is possible to change the angle while maintaining the plurality of heat-radiating plates, which face the central axis of the shadowless lamp, uniformly at the same angle when changing the angles of alignment of the heat-radiator plates through a coupling using brackets between the heat-radiating plates constituting a plurality of segments. To this end, the LED shadowless lamp of the present invention comprises: a plurality of heat-radiating plates which are contiguously disposed in the circumferential direction while forming a single circular shape overall; a base plate coupled to the heat-radiating plates; and a plurality of LEDs which are coupled to the base plate and are formed so as to be perpendicular to the tangential planes of the heat-radiating plates in each coupling position, and the crosssections of the heat-radiating plates are formed as concave curved surfaces facing the irradiation directions of the LEDs.
