Title:
LED ILLUMINATION DEVICE FOR SPOTLIGHTING
Document Type and Number:
WIPO Patent Application WO/2016/098932
Kind Code:
A1
Abstract:
The present invention relates to an LED illumination device for spotlighting, comprising: a lower case part having a plurality of planar inner side surfaces so that a light-emitting hole on the bottom surface thereof can be a polygonal shape; an upper case part, positioned above the lower case part, for receiving a power supply unit; substrates which are respectively coupled to the planar inner side surfaces of the lower case part and in which LEDs are mounted such that a light-emitting surface can be directed to the central part of the polygon; and a plurality of heat dissipation fins which are protrudingly positioned along the circumference of the lower case part, wherein the spaces between the heat dissipation fins communicate in the longitudinal direction of the lower case part. The present invention is configured such that a case is manufactured as a single structure and components such as a power supply unit, LED-mounted substrates, reflective plates, etc. can be assembled within the case through the light-emitting hole. As such, the present invention can minimize manufacturing costs and thus, has the effect of hastening the commercialization of LED illumination devices for spotlighting.
