Abstract:
A lighting module may be provided that includes: a bottom plate having thermally a heat radiating characteristic; a light emitter comprising a substrate disposed on the bottom plate and a plurality of light emitting devices disposed on the substrate; an optical structure covering the light emitter, the optical structure comprising an outer frame surrounding the substrate and a plurality of lenses corresponding to the plurality of the light emitting devices; an upper case covering the optical structure and coupled to the bottom plate and having an opening for allowing lights which have passed through the plurality of lenses of the optical structure; and a gasket disposed between the outer frame of the optical structure and the upper case.
Abstract:
Disclosed is an LED lighting device of which the number of LED modules thereof is changeable according to power consumption. Through a structural change of the module, heat radiation and waterproof can be greatly improved and the size, weight and manufacturing cost can be reduced. Also, a fastening bolt allows the module to be simply attached and separated and maintenance, repair and stability can be improved by providing a wiring space inside the device. Further, there is an advantage of additionally adding a light detection sensor through a cover. The LED lighting device according to the embodiment includes a plurality of heat radiating plates; at least one light source module disposed on one surface of the heat radiating plate.
