Document Type and Number:
WIPO Patent Application WO/2017/086548
Kind Code:
A1
Abstract:
The present invention relates to an LED lighting device having a pipe shape, and the objective of the present invention is to provide an LED lighting device having a pipe shape, the LED lighting device being capable of providing LED lighting exhibiting a unique aesthetic feeling by emitting an LED light source at the body of a predetermined structure, which includes one pair of pipes having a predetermined length. To this end, the LED lighting device having a pipe shape, according to the present invention, comprises: an inner tube made of light diffusion PC, which has a predetermined diameter and a predetermined length; an outer tube made of a transparent or semitransparent material and fitted into and coupled to the outer circumferential surface of the inner tube; a coupling member, which has a cylindrical shape of which top and bottom surfaces are open, and is fixed and coupled to one end or both ends of the outer tube in a state in which the substrate mounting part is formed to protrude in a flange shape in the center of the inner circumferential surface of the coupling member; an LED substrate, which is formed in a circular plate shape having a hole drilled in the center thereof, so as to be fixed and provided to the substrate mounting part of the coupling member, and has a plurality of LEDs arranged on one surface thereof so as to emit a predetermined light source toward the inner tube and the inner circumferential surface side of the outer tube; and a finishing member, which has a circular plate shape having a hole drilled in the center thereof, and is coupled to the open surface of the coupling member on which the LED substrate is provided, so as to seal the inside thereof in a state in which an extension part having a predetermined height in the vertical direction is formed to protrude from the inner circumferential surface of the hole.
