Description

LED 어레이 패키지{LED array package}LED array package

본 고안은 LED가 탑재되는 LED 하우징을 LED 어레이 기판에 고정설치하여 이루어진 LED 어레이 패키지에 관한 것이다. The present invention relates to an LED array package formed by fixing an LED housing on which an LED is mounted to an LED array substrate.

일반적으로 LED는 초소형이고, 전력소모량이 적게 들고, 발열이 낮으며, 휘도가 높고 수명이 길어서 가로등이나 집어등을 포함한 조명등 및 LCD에 사용되고 있다. In general, LED is very small, low power consumption, low heat generation, high brightness and long life has been used in lighting and LCD, including street lamps and catching lights.

이와 같이 조명등 및 LCD에 사용하기 위한 LED는 LED 하우징이 탑재된 LED 어레이 기판에 LED가 복수개 설치되어 구성되는데, 이와 관련하여 특허문헌 1이 개시되어 있다. As described above, a LED for use in a lamp and an LCD includes a plurality of LEDs installed on an LED array substrate on which an LED housing is mounted. In this regard, Patent Document 1 discloses.

특허문헌 1의 LED 패키지는 상부로 돌출된 본딩부를 구비하며 금속 하우징 수용 홀의 서로 대향하는 양측에 쌍으로 형성되는 는 복수 개의 리드, 리드를 지지하는 지지부 및 금속 하우징 수용 홀을 구비하는 리드 프레임 기판; 금속 하우징 수용 홀에 수용되며, 발광 다이오드 수용 공간, 발광 다이오드 수용 공간을 관통하며 본딩부가 삽입되는 4개의 본딩부 삽입 홀, 발광 다이오드 수용 공간의 하부에 형성되며 측면에 방열핀이 형성되는 평판형의 방열부 및 렌즈가 장착되며 방열부와 함께 발광 다이오드 수용 공간을 정의하는 측벽을 구비하는 복수 개의 금속 하우징; 및 리드 프레임 기판의 본딩부와 금속 하우징의 본딩부 삽입 홀을 절연하는 절연 부재를 포함하여 구성된다. The LED package of Patent Document 1 includes a lead frame substrate including a plurality of leads formed in pairs on opposite sides of the metal housing accommodating hole and having a bonding portion protruding upward, a support for supporting the leads, and a metal housing accommodating hole; It is accommodated in the metal housing accommodation hole, the four bonding portion insertion hole penetrates the light emitting diode accommodation space, the light emitting diode accommodation space, the bonding portion is inserted, the flat heat dissipation is formed in the lower portion of the light emitting diode accommodation space and the heat radiation fin is formed on the side A plurality of metal housings having a side and a lens and having sidewalls defining a light emitting diode receiving space together with a heat dissipating portion; And an insulating member that insulates the bonding portion of the lead frame substrate and the bonding portion insertion hole of the metal housing.

상기 절연부재는 파이프 형상으로 형성되어, 도 4에 도시된 바처럼 4개의 본딩부가 4개의 절연부재에 삽입된 다음, 절연부재가 본딩부 삽입 홀에 삽입된다. 이렇게 리드 프레임 기판, 절연부재 및 금속 하우징이 조립된 다음, 절연부재를 용융시켜 금속 하우징과 리드 프레임 기판을 실링한다. 절연부재에 의해 금속 하우징과 리드 프레임 기판은 서로 통전되지 않으면서 고정된다. The insulating member is formed in a pipe shape, as shown in FIG. 4, four bonding parts are inserted into four insulating members, and then the insulating member is inserted into the bonding part insertion holes. After the lead frame substrate, the insulating member and the metal housing are assembled, the insulating member is melted to seal the metal housing and the lead frame substrate. By the insulating member, the metal housing and the lead frame substrate are fixed without being energized to each other.

절연부재는 전기적으로 비전도성인 글라스 및 절연성 고분자로 이루어지는 군 중에서 선택된 물질로 이루어지며, 금속 하우징과 리드 프레임 기판을 도금한 물질보다 낮은 온도에서 용융되는 물질로 이루어진다. The insulating member is made of a material selected from the group consisting of electrically non-conductive glass and insulating polymer, and is made of a material that is melted at a lower temperature than the material that plated the metal housing and the lead frame substrate.

절연부재를 용융시켜 금속 하우징을 리드 프레임 기판에 고정설치하는 방식에 대해서는 개시되어 있지 않지만, 이 방식은 4개의 홀을 스폿 용접에 의해 절연부재를 용융시키는 방식이다. Although the method of melting the insulating member to fix the metal housing to the lead frame substrate is not disclosed, this method is a method of melting the insulating member by four spot welding.

그런데 이와 같은 특허문헌 1은 다음과 같은 문제점을 가지고 있다. However, such Patent Document 1 has the following problems.

첫째, 4개의 본딩부에 각각 4개의 절연부재를 삽입해야 하므로 작업시간이 많이 소요되어 생산성이 저하된다. First, since four insulating members must be inserted into each of the four bonding parts, a lot of work time is required and productivity is reduced.

둘째, 각각의 금속 하우징을 스폿 용접에 의해 리드 프레임 기판에 고정설치해야 하므로 작업시간이 많이 소요되어 생산성이 저하된다. Second, since each metal housing must be fixed to the lead frame substrate by spot welding, a lot of working time is required and productivity is lowered.

셋째, 스폿 용접에 의해 절연부재를 용융시키는 방식이므로 용접불량으로 인한 품질불량이 발생된다. Third, since the insulation member is melted by spot welding, quality defects are generated due to poor welding.

넷째, 스폿 용접불량으로 인해 절연부재가 용융되지 않는 경우에는 금속 하우징과 리드 프레임 기판이 통전되어 쇼트현상이 발생된다. Fourth, when the insulating member is not melted due to the spot welding failure, the metal housing and the lead frame substrate are energized to generate a short phenomenon.

이와 같이 절연부재를 사용하지 않고 스폿 용접을 하지 않음에 따라 생산성이 향상되고, 품질불량의 염려가 없고, 절연성능이 향상되어 쇼트현상의 발생이 없다. As such, when spot welding is not performed without using the insulating member, productivity is improved, there is no concern about poor quality, and the insulating performance is improved, so that there is no short phenomenon.

이와 같은 본 고안의 실시예의 LED 어레이 패키지는 3W의 LED를 구현할 수 있다. 현재의 가로등은 최소 200W 이상의 빛을 필요로 하는데, 이 경우 최소 200W를 구현하려면 특허문헌 1의 경우는 2W를 구현하는 LED가 장착되므로 LED 100개가 필요한 반면에 본 고안은 70개 정도의 LED면 특허문헌 1과 동일한 효율을 가질 수 있으며 원가절감과 LED 어레이 패키지를 소형화할 수 있어서 다각적으로 활용이 가능하다. Such an LED array package of an embodiment of the present invention can implement a 3W LED. Current streetlights require at least 200W of light. In this case, in order to implement at least 200W, Patent Document 1 requires 2 LEDs to implement 2W, whereas the present invention requires about 100 LEDs. It can have the same efficiency as that of Document 1 and can be utilized in various ways because the cost reduction and the LED array package can be miniaturized.
