Title:
OPTICAL SEMICONDUCTOR LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/182884
Kind Code:
A1
Abstract:
The present invention relates to an optical semiconductor lighting device capable of improving heat-dissipation performance by inducing natural convection current over the interior and exterior thereof, having simple installation and construction, capable of actively coping with various construction environments such as those which expand and shrink according to assembly engagement, certainly carrying out waterproofing and sealing maintenance, and capable of improving workability even in maintenance management such as repairing and replacement, by allowing air to naturally flow therethrough between a first light-emitting module and a second light-emitting module arranged to be parallel with gap of a mutually predetermined distance therebetween and allowing a first sealing part provided to the side surfaces of a casing part and a second sealing part provided to an upper part of the casing part to dually prevent the inflow of humidity and foreign substances.
