본 고안은 브라운관의 판넬내면에 형광면을 노광형성하기 위한 노광장치의 개선에 관한 것으로, 특히 이러한 노광장치에 설치사용되는 광원장커버의 구조를 개선하여 커버의 설치성을 좋게 하면서 보다 양호한 노광결과를 얻어낼 수 있도록 하는데에 주안점을 두어 안출한 것이다.The present invention relates to an improvement of an exposure apparatus for exposing a fluorescent surface to a panel inner surface of a CRT. In particular, the structure of a light source cover used in such an exposure apparatus is improved to improve the installation of the cover and to provide better exposure results. The main focus was on making it possible to obtain.
이러한 브라운관의 형광면 노광장치는 브라우관 판넬내면에 도포되어진 형광물질층을 소정 패턴으로 노광시켜 목적한 바의 형광면을 형성하기 위한 광원수단을 구비하게 되는데, 종래의 노광장치는 상기 그 광원 수단으로서 제1도에 도시된 바와 같이램프 하우징(1)과, 이 램프하우징(1)의 내중심에 설치되는 수은램프(2)와, 상기 램프(2)로 부터의 빛을 그 광공(3')을 통해 설정된 광량 및 형태로 제한 통과시켜 판넬 내면에이르게 하기 위해 램프(2)상에 결합설치되는 광원장커버(3)등의 요소들을 포함하는 구성으로 되어 있었는 바, 이는 상기 광원장커버(3)를 램프(2)상에 센터를 정확히 맞추어 설치해 주기가 매우 어려울 뿐만 아니라 센터를 정확히 맞추어 설치된 광원장커버도 장치의 상용중 램프(2) 상에서 이리저리 유동되기 쉬워 노광불량을 초래하는 일이 잦은 문제점이 있었다.The fluorescent tube exposure apparatus of the CRT is provided with a light source means for exposing the fluorescent material layer applied on the inner surface of the brown tube panel in a predetermined pattern to form a desired fluorescent surface. As shown in FIG. 1, the lamp housing 1, the mercury lamp 2 installed at the inner center of the lamp housing 1, and the light from the lamp 2 are applied to the light holes 3 '. It was configured to include elements such as light source cover 3, which is installed on the lamp 2 in order to limit the amount of light and the form set through the panel to reach the inner surface of the panel, which is the light source cover 3 It is very difficult to install the center on the lamp 2 precisely, and the light source cover installed with the center is also easy to flow on and off the lamp 2 during commercial use of the device. There was a frequent problem.
본 고안은 이러한 종래의 문제점을 해소하기 위해 안출한 것으로, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is devised to solve such a conventional problem, it will be described in detail based on the accompanying drawings as follows.
제2도는 본 고안에 따른 형광면 노광장치의 구성요부인 광원수단의 한 바림작한 구성례를 도시한 것인데, 본 고안의 노광장치는 노광에 필요한 그 광원수단으로서 상기에 도시된 예와 같은 광원수단을 구비하는 것을 특징으로 하는 것이다.FIG. 2 shows an exemplary configuration of a light source means which is a constituent part of the fluorescent surface exposure apparatus according to the present invention. The exposure apparatus of the present invention uses the same light source means as the example shown above as the light source means required for exposure. It is characterized by including.
상기 광원수단은 내중앙에 수은램프(11)가 성치된 통상의 램프하우징(10)과, 이 램프하우징(10)의 광공(12)이 설치된 외측에 링체(13)를 통해 결합설치된 본 고안에 따른 광원장커버(14)를 포함하는 구성으로 되어 있다.The light source means has a conventional lamp housing 10 having a mercury lamp 11 in the center and the present invention coupled to the outside through the ring body 13 is installed in the light hole 12 of the lamp housing 10 The light source cover 14 is configured to include.
도시된 예에서 광원장커버(14)는 이를 링체(13)의 내측에 예컨데 나사결합식으로 결합시킨 후 이 링체(13)를 램프하우징(10)의 결합부(15) 내측에 나사결합시켜서 램프 하우징(10)에 결합설치된다.In the illustrated example, the light source cover 14 is screwed to the inside of the ring body 13, for example, and then screwed to the inside of the coupling part 15 of the lamp housing 10. It is coupled to the housing 10.
상기 광원장커버(14)는 제2도, 3도에 도시된 바와 같이 그 상면으로 부터 하면을 향해 테이퍼지게 요입형성된 광안내면(14a)과, 이 광 안내면(14a)의 중앙에 사리한 소정형태의 광공(14b)과, 커버의 상면적소에 제공된 위치안내 표시부(14c)를 가진다. 바람직한 실시예에 있어서 상기 광안내면(14a)과 커버하면간의 각도는 적어도 20°가 되도록 한다.The light source field cover 14 has a light guide surface 14a tapered from its upper surface toward its lower surface as shown in FIGS. 2 and 3, and a predetermined shape in the center of the light guide surface 14a. A light hole 14b and a position guide display portion 14c provided at an upper surface area of the cover. In a preferred embodiment, the angle between the light guide surface 14a and the bottom surface of the cover is at least 20 °.
도면중 미설명부호 16은 ○링, 17은 보호 유리판을 각각 나타낸다.In the drawings, reference numeral 16 denotes a ring and 17 denotes a protective glass plate, respectively.
이와같이 구성된 본 고안은 상기 광원장커버(14)가 링체(13)와 결합부(15), 표시부(14c)등의 수단을 통해 램프하우징(10)상의 소망되는 위치에 정확히 결합 고정될 수 있을 뿐만 아니라 견실안정적인 결합상태로 사용중 유동이 없기 때문에 커버의 설치불량이나 유동으로 인한 노광불량을 완전제거할 수 있고, 상기 광원장커버(14)에 있어서 광공(14b)을 둘러싼 광안내면(14a)의 작용으로 램프(11)로 부터의 빛을 노광대상면쪽으로 보다 양호하게 안내시킬 수가 있기 때문에 이로써 노광되어지는 형광면의 품위를 더욱 향상시킬 수 있게 된 신규유용한 효과를 지닌 것이다.According to the present invention configured as described above, the light source cover 14 may be fixedly coupled to a desired position on the lamp housing 10 through means such as the ring body 13, the coupling part 15, and the display part 14c. In addition, since there is no flow during use in the state of firmly coupled, it is possible to completely eliminate the exposure failure due to the installation failure or flow of the cover, the action of the light guide surface 14a surrounding the light hole 14b in the light source cover 14 As a result, the light from the lamp 11 can be better guided to the surface to be exposed, thereby making it possible to further improve the quality of the fluorescent surface to be exposed.
