일반적으로 광학은 광(光, 빛)에 관련된 현상을 다루는 것으로, 광학의 반사 또는 굴절 등의 현상을 이용하여 소정의 목적을 달성하기 위한 장치를 광학장치, 광학수단, 광학모듈 등 다양하게 칭하고 있다.In general, optics deals with phenomena related to light, and various apparatuses for achieving a predetermined purpose using phenomena such as reflection or refraction of optics are variously referred to as optical devices, optical means, and optical modules. .
상기와 같은 장치는 광을 발광할 수 있는 발광수단을 구비하도록 설계되는데, 이때 발광되는 광은 렌즈(Lens)의 형태에 따라 다양한 출력방향과 거리를 갖을 수 있다.Such a device is designed to have light emitting means for emitting light, wherein the light emitted may have various output directions and distances depending on the shape of the lens.
그러나 렌즈(Lens)를 발광수단과 함께 형성하는 경우, 발광수단에서 발광되는 광의 출력방향과 거리를 변경하고 할 때, 발광수단까지 함께 교체해야하고 이는 교체에 따른 비용소모가 증가되는 문제점이 있었다.However, when the lens (Lens) is formed together with the light emitting means, when changing the output direction and distance of the light emitted from the light emitting means, it must be replaced with the light emitting means, which has a problem in that the cost of the replacement is increased.
이에 따라, 렌즈를 별도로 구비하되 상기 렌즈가 발광수단에 고정될 수 있도록 하는 홀더(Holder)의 기술 개발이 이루어지고 있는 실정이다.Accordingly, there is a situation in which a technology for developing a holder is provided, in which a lens is separately provided so that the lens can be fixed to the light emitting means.
홀더의 기술과 관련하여 등록특허공보 제10-0700883호에는 발광 소자 패키지 및 그의 제조 방법이 기재되어 있다.Regarding the technology of the holder, Korean Patent Publication No. 10-0700883 describes a light emitting device package and a manufacturing method thereof.
위의 기술은 한 쌍의 리드들과; 리드들 중, 하나의 리드 상부에 접착되는 발광 소자와; 발광 소자의 전극단자들과 한 쌍의 리드들을 각각 전기적으로 연결하는 도전부와; 개구가 형성되어 있고 렌즈가 개구에 삽입 및 고정되어 있고, 한 쌍의 리드들 상부에 렌즈가 발광 소자 상부에 위치되어 있는 렌즈 홀더와; 렌즈 홀더의 상부 및 렌즈를 노출시키고, 리드들 각각의 일부를 노출시키는 몰딩부;로 구성된다.The above technique includes a pair of leads; A light emitting element adhered to an upper portion of one of the leads; A conductive portion electrically connecting the electrode terminals of the light emitting element and the pair of leads to each other; A lens holder in which an opening is formed, the lens is inserted and fixed in the opening, and the lens is positioned above the light emitting element on the pair of leads; And a molding part exposing the upper portion of the lens holder and the lens and exposing a portion of each of the leads.
즉, 위에 기재된 기술은 발광 소자 패키지에 관한 것으로서, 렌즈 홀더에 대해 기재하고 있는데, 이는 절연성 접착제를 통해 한 쌍의 리드들과 접착되기 때문에 홀더를 통해 별도로 렌즈를 구비할 수 있음에도 불구하고, 렌즈의 교체가 용이하지 않으며 렌즈의 교체를 위해서 홀더의 접착을 떼어내야 하는 번거로움이 여전히 존재한다.That is, the above-described technology relates to a light emitting device package, which describes a lens holder, which may be provided separately from the lens because the lens is adhered to the pair of leads through the insulating adhesive. It is not easy to replace and there is still the hassle of peeling off the holder for lens replacement.
따라서, 홀더에 렌즈를 고정할 수 있는 수단을 구비하여 렌즈를 적용시킬 수 있으면서, 렌즈의 설치와 제거가 가능하도록 하여 렌즈의 교체를 용이하게 할 수 있는 기술의 개발이 요구된다.Accordingly, there is a need for the development of a technology capable of easily installing and removing the lens by providing a means for fixing the lens to the holder and enabling the installation and removal of the lens.

이하, 도면을 참조하여 설명하기에 앞서, 본 발명의 요지를 드러내기 위해서 필요하지 않은 사항 즉 통상의 지식을 가진 당업자가 자명하게 부가할 수 있는 공지 구성에 대해서는 도시하지 않거나, 구체적으로 기술하지 않았음을 밝혀둔다.Before describing the present invention with reference to the drawings, it is not shown or specifically described for the matters that are not necessary to reveal the gist of the present invention, that is, those skilled in the art can obviously add. Make a note.
일반적으로 광학모듈이라 함은, 광학의 반사 또는 굴절 등의 현상을 이용하여 소정의 목적을 달성하기 위한 광학 구성을 의미할 수 있다.In general, the optical module may mean an optical configuration for achieving a predetermined purpose by using a phenomenon such as reflection or refraction of the optical.
그리고 본 발명은, 상기한 광학모듈에 구성되는 발광수단으로부터 발광되는 광의 출력방향 및/또는 거리를 보정할 수 있는 몰드 가공된 렌즈를 포함하는 리크 방지 타입 광학용 홀더에 관한 것이다.The present invention also relates to a leak-proof type optical holder including a molded lens that can correct an output direction and / or a distance of light emitted from the light emitting means constituted in the optical module.
이러한 본 발명에 따른 몰드 가공된 렌즈를 포함하는 리크 방지 타입 광학용 홀더를 첨부된 도면을 통해 설명한다.The leakage preventing optical holder including the molded lens according to the present invention will be described with reference to the accompanying drawings.
도 1은 본 발명에 따른 몰드 가공된 렌즈를 포함하는 리크 방지 타입 광학용 홀더의 구성을 나타낸 것으로, 광학용 홀더의 사시형상(a) 및 광학용 홀더의 단면형상(b)을 나타내고 있다.Fig. 1 shows the structure of a leak-proof optical holder including a molded lens according to the present invention, and shows a perspective shape (a) of the optical holder and a cross-sectional shape (b) of the optical holder.
그리고 도 2는 본 발명에 따른 몰드 가공된 렌즈를 포함하는 리크 방지 타입 광학용 홀더가 발광수단과 결합되는 일예를 나타낸 것이다.2 shows an example in which a leak-proof type optical holder including a molded lens according to the present invention is combined with a light emitting means.
도 1의 (a)에서 볼 수 있듯이, 본 발명의 홀더(100)의 외관은, 베이스(110), 발광수단 수용부(120) 및 렌즈 수용부(130)를 포함할 수 있으며, 베이스(110)에서부터 렌즈 수용부(130)까지 길이방향으로 관통되고, 각 재질은 금속(Metal)으로 구성될 수 있다.As shown in (a) of FIG. 1, the exterior of the holder 100 of the present invention may include a base 110, a light emitting means accommodating part 120, and a lens accommodating part 130, and a base 110. ) Penetrates in the longitudinal direction from the lens receiving portion 130, and each material may be made of metal.
베이스(110)는 첨부된 도면의 도 2에서 볼 수 있듯이, 발광수단(Chip)이 포함된 기판(Substrate)에 결합되는 것으로, 그 하면에 기판과 결합하기 위한 연결 돌출부(111)가 구비된다(도 1의 (b) 참조).As shown in FIG. 2 of the accompanying drawings, the base 110 is coupled to a substrate (Substrate) including a light emitting means (Chip), and a connecting protrusion 111 for engaging with the substrate is provided on the bottom surface thereof ( See FIG. 1 (b)).
이때 연결 돌출부(111)는 용접 가능한 재질로 구성될 수 있다.In this case, the connection protrusion 111 may be made of a weldable material.
즉, 연결 돌출부(111)를 용접 가능한 재질로 구성하고, 이에 열과 압력을 가해 연결 돌출부(111)가 용융되어 기판에 직접 부착됨으로써 결합력을 높일 수 있다.That is, the connecting protrusion 111 may be made of a weldable material, and the connecting protrusion 111 may be melted and directly attached to the substrate by applying heat and pressure thereto to increase the bonding force.
한편 다른 일예로서, 연결 돌출부(111)를 금속재질로 구성하여 용접작업 없이 홀더(100)가 기판에 결합되도록 구성할 수도 있다.Meanwhile, as another example, the connecting protrusion 111 may be made of a metal material so that the holder 100 may be coupled to the substrate without welding.
이는 기판의 연결 돌출부(111)에 대응되는 위치에 홈을 구성하고 연결 돌출부(111)가 기판의 홈에 끼워짐으로써, 홀더(100)가 기판에 설치되도록 하는 것이다.This constitutes a groove at a position corresponding to the connection protrusion 111 of the substrate, and the connection protrusion 111 is fitted into the groove of the substrate, so that the holder 100 is installed on the substrate.
단, 상기와 같은 일예에서는 도면에 표시되지는 않았지만, 홀더(100)가 기판에 설치되는 경우, 견고하게 고정되기 위하여 연결 돌출부(111)에 기판의 홈의 원주 방향으로 연장되는 별도의 돌출부재(도면에 미표시)를 더 포함하여 돌출부재를 통해 홀더(100)가 기판에 고정될 수 있도록 할 수 있다.However, although not shown in the drawings in the above example, when the holder 100 is installed on the substrate, in order to be firmly fixed to the connecting protrusion 111, a separate protruding member extending in the circumferential direction of the groove of the substrate ( Not shown in the drawing) may be further included so that the holder 100 can be fixed to the substrate through the protruding member.
