The shadowless LED lamp comprises an LED device, a lens, a substrate, and a heat sink, wherein coupling slots are formed in the substrate and the heat sink; the lens includes a main body having a slot into which the LED device can be inserted, a coupling unit having protrusions which are adapted for insertion into the coupling slots formed in the substrate and the heat sink, and a support unit which is formed on a side of the main body where the main body is joined with the substrate and which supports the coupling unit so that the coupling unit may stop being inserted into the coupling slots; and a fixing unit for fixing the lens by being coupled to one end of the coupling unit of the lens is included. The shadowless LED lamp is characterized in that the lens, the substrate and the heat sink are integrally coupled together, since the coupling unit of the lens passes through the coupling slots formed in the substrate and the heat sink and is coupled to the fixing unit.

이싱- 살펴본 바와 같이， 본 발명에 따른 렌즈 (200)는 다수의 렌즈 (200)가 각각 개별적으로 방열판 (400)과 직접 결합 되는 구조이며 상기 렌즈 (200)의 지지부 (220)가 원형을 이룸으로., 평판형 방열판뿐만 아니라 곡면을 이루는 방열판 (400)에 있어서도 렌즈 (200)와 방열판 (400)과의 직교 각도 정밀성이 향상될 수 있다. 이처럼 개별 렌즈 (200)가 곡면을 이루는 방열관 (400)에서도 비醫어지지 않고 정확하게 접촉 면과 수직을 이룸으로 방열판 (400)의 곡면이 이루는 초점을 향해 LED 광이 정확하게 집광 되도톡 하여 집광 성능이 향상된다, 또한， 기판 (300)과 방열판 (400) . 렌즈 (200)를 통해 한번에 결합함으로 기판 (300)과 방열관 (400)의 접촉 면적이 넓어지고 LED 기판 모들의 방열이 용이하게 되어 LED의 수명을 강화시킬 수 있게 된다. Yixing- As described above, the lens 200 according to the present invention is a structure in which a plurality of lenses 200 are directly coupled to the heat sink 400, respectively, and the lens 200 Since the support part 220 is circular, the orthogonal angle precision of the lens 200 and the heat sink 400 may be improved not only in the flat heat sink but also in the heat sink 400 forming a curved surface. In this way, the individual lens 200 does not rub even in the heat dissipation tube 400 that forms a curved surface, and is precisely perpendicular to the contact surface, thereby condensing LED light toward the focal point of the curved surface of the heat dissipating plate 400, thereby condensing performance. This improves, further, the substrate 300 and the heat sink 400 . By combining the lens 200 at a time, the contact area between the substrate 300 and the heat dissipation tube 400 is widened and heat dissipation of the LED substrate models is facilitated, thereby enhancing the life of the LED.
이상에서는 본 발명을 구체적인 실시예를 통하여 설명하였으나, 당업자라면 본 발명의 취지 및 범위 1ᅳ 벗어나지 않고 수정, 변경을 할 수 있디.. 따라서 본 발명의 상세한 설명 및 실시예로부터 본 발명이 속하는 기술분야에 속한 사람이 용이하게 유추할 수 있는 것은 본 발명의 권리범뷔에 속하는 것으로 해석된다.  The present invention has been described above through specific embodiments, but those skilled in the art can make modifications and changes without departing from the spirit and scope of the present invention. Therefore, the present invention belongs to the detailed description of the present invention and examples. What can be easily inferred by the person belonging to is interpreted as belonging to the right category of the present invention.
