Title:
COB LIGHTING DEVICE HAVING IMPROVED LIGHT-DISTRIBUTION, ILLUMINANCE, AND HEAT -DISSIPATION EFFICIENCY
Document Type and Number:
WIPO Patent Application WO/2016/208824
Kind Code:
A1
Abstract:
The present invention relates to a COB lighting device having improved light-distribution, illuminance, and heat-dissipation efficiency that: can reflect emitted light with a reflective plate to prevent glare caused by direct rays of the light; can allow the light travelling forwards from the reflector to have travel paths similar to each other to minimize the amount of light leaked out of an illuminated area, thereby improving luminous intensity; and can allow the light to be uniformly supplied without being limited to one point, the COB lighting device comprising: a polygonal prismatic heat-dissipation rod having a thermal conductor formed on at least one of the inside and the outside thereof; a plurality of lighting modules attached to the outer circumferential surface of the heat-dissipation rod in the longitudinal direction, each of which has a plurality of lighting elements arranged in a line; a reflector having the shape of a container that is open at an opposite end thereof, wherein the heat-dissipation rod is fixedly inserted into the central portion of the reflector, and the reflector has a plurality of planar reflective plates that are formed such that side surfaces thereof continually make contact with each other; a heat-dissipation plate assembly that makes contact with an end portion of the heat-dissipation rod and releases, to the outside, heat conducted from the heat-dissipation rod; and a stabilizer provided on a side of the heat-dissipation plate assembly to supply power to the lighting modules.
