Title:
LED ASSEMBLIES HAVING A BALL JOINT SUPPORT STRUCTURE, ATTACHABLE/DETACHABLE LED ASSEMBLY BLOCKS USING SAME AND LED LIGHTING APPARATUS HAVING AN ATTACHABLE/DETACHABLE BLOCK ASSEMBLY STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2011/081337
Kind Code:
A3
Abstract:
The present invention relates to an LED assembly, an attachable/detachable LED assembly block using the same and an LED lighting apparatus having an attachable/detachable block assembly structure, wherein the LED assembly adopts a ball joint support structure to maximize a uniformity ratio of illuminance, prevent glare and achieve simple and perfect attachable/detachable assembly structure, thereby allowing for ease of assembly and maintenance and significantly reducing manufacturing costs. The LED lighting apparatus of the present invention comprises: a plate type housing body; a plurality of LED assembly blocks assembled one at a time along the outer periphery of the housing body, wherein each of the LED assembly blocks has a block body with an inner surface on which a plurality of LED assemblies are mounted at a discrete orientation angle such that each of the LED assemblies serves as a discrete light source; and a plurality of protection covers for covering the respective LED assemblies mounted on the respective LED assembly blocks. Each of the LED assemblies has an LED package having LED chips embedded therein, and the LED package is movably supported between a movable support unit and a fixed support unit by the ball joint support structure, such that the orientation angle of light emitted from LED chips can be freely set by adjusting the angle of the movable support unit.
