Description

조명장치Lighting equipment

제1도는 폴리탄산수지의 성형체 및 유기형강물감 또는 안료가 혼합되어 있는 폴리탄산 수지의 성형체의 광흡수 곡선을 보인도.FIG. 1 shows light absorption curves of a molded article of polycarbonate resin and a molded article of polycarbonate resin in which an organic form steel pigment or pigment is mixed.

제2도는 본 발명의 첫 번째 실시예의 조명장치를 설명한도.2 is a view for explaining the lighting apparatus of the first embodiment of the present invention.

제3도 내지 제7도는 본 발명의 다른 실시예들의 조명장치를 설명한도.3 to 7 illustrate the lighting apparatus of other embodiments of the present invention.

제8도는 본 발명의 조명장치가 액정 디스플레이의 후광으로서 사용되는 실시예를 보인도.8 shows an embodiment in which the lighting apparatus of the present invention is used as a halo of a liquid crystal display.

본 발명은 조명장치에 관한 것이며, 특히 고광도를 지닌 평편조면을 얻기 위한 조명장치에 관한 것이다. 폴리탄산 수지가 이중 결합 벤젠 화학 구조식에서 π-π*에 의한 전자들의 전이 흡수 때문에, 제1도에 도시한 바와같이 단파장의 가시광선 영역(특히, 녹색 및 파랑색)에 있는 광을 흡수하고 합성광이 노랑색 또는 오렌지색으로 착색되며 수지가 투명하게 나타나지 않는다. 제1도에서 가로축에 파장을, 세로축에 광투과를 프롯트한다. 폴리탄산의 광투과는 곡선 1로 도시하였다.The present invention relates to a lighting device, and more particularly to a lighting device for obtaining a flat braided surface having high brightness. Due to the transition absorption of electrons by π-π * in the double bond benzene chemical formula, the polycarbonate resin absorbs and synthesizes light in the short wavelength visible region (particularly green and blue) as shown in FIG. The light is colored yellow or orange and the resin does not appear transparent. In FIG. 1, the wavelength is plotted on the horizontal axis and the light transmission on the vertical axis. The light transmission of polycarbonate is shown by curve 1.

이 결점을 제거하기 위하여, 푸른색에 해당하는 파장의 투과를 최대로 하고 푸른 색조를 띠게하기 위하여 노랑색 또는 오렌지색을 최대로는 흡수하는 안료(보통 청효제(blueing agent)라 부른다. )를 혼합시키는 방법을 채택하여 왔었다. 폴리탄산 혼합된 청효제의 광투과를 제1도의 곡선 2로 도시하였다.To eliminate this drawback, a mixture of pigments (usually called blueing agents) that absorb the maximum of yellow or orange in order to maximize the transmission of the wavelength corresponding to blue and to have a blue tint. I have adopted the method. The light transmission of the polycarbonate mixed leach agent is shown in curve 2 of FIG.

그러나 곡선 2의 왼쪽 반에서는 흡수가 많고 수지는 파랗고 빨간 영역에서 투명하지 아니하며, 또한 전체 파장의 효율적인 투과 관점에서 수지는 실제 유용하지 못하다. 고 효율로 전체 가시광선 파장 영역에 광을 투과할 수 있고 고 광도를 지닌 평면 조명을 얻을 수 있는 조명장치를 제공하는 것이 본 발명의 일반 목적이다.However, in the left half of curve 2, the absorption is high, the resin is not transparent in the blue and red regions, and the resin is not practically useful in terms of efficient transmission of the entire wavelength. SUMMARY OF THE INVENTION It is a general object of the present invention to provide an illumination device that can transmit light in the entire visible light wavelength region with high efficiency and obtain flat illumination with high brightness.

본 발명에 의하면, 안에 유기형광물감을 가지는 투명수지로 이루어진 평판과 평판 배후면의 일부상에 배열된 광반사 수단으로 구성된 조명장치를 제공하며 여기에서 평판이 적어도 끝면 일부로부터 입사하는 광이 평판 표면의 적어도 일부로부터 방사된다.According to the present invention, there is provided an illuminating device comprising a flat plate made of a transparent resin having an organic fluorescent substance therein and a light reflecting means arranged on a part of the rear surface of the flat plate, wherein the light incident from at least a portion of the end face of the flat plate has a flat surface. Is radiated from at least a portion of the.

본 발명에 유효 적절한 투명 수지로서는 폴리탄산, 폴리스티렌, 폴리메틸 메타크릴레이트, 폴리메틸 메타크릴레이트와 폴리비닐리덴 플루오리드와의 혼합물이다.Suitable transparent resins effective in the present invention are mixtures of polycarbonate, polystyrene, polymethyl methacrylate, polymethyl methacrylate and polyvinylidene fluoride.

본 발명에 유효 적절한 유기형광물감들로서는 페닐렌형 물감들, 나프탈이미드형 물감들, 쿠마린형 물감들이다.Suitable organic fluorescent paints effective in the present invention are phenylene paints, naphthalimide paints, and coumarin paints.

전체 가시광선 파장 영역의 에너지는 유기형광물감 예를 들면 폴리탄산 수지 안으로 혼합시킴으로써 효율적으로 투과되기 때문에 가시광선파장 영역을 넘는 자외선 파장 영역의 광 에너지를 흡수하고 푸른 형광색을 흡수하며 파랗거나 하얗게 나타나게 된다. 나프탈이미드형 형광물감을 다음 공식으로 나타내는 폴리탄산 수지의 투과에 따라 파장이 결정된다.The energy in the entire visible wavelength range is efficiently transmitted by mixing into organic fluorophores, for example polycarbonate resins, so that it absorbs light energy in the ultraviolet wavelength range beyond the visible wavelength range, absorbs blue fluorescent colors, and appears blue or white. . The wavelength is determined in accordance with the transmission of the polycarbonate resin represented by the following formula for naphthalimide-type fluorescent paint.

여기에서 R은 중량으로 0.01% 혼합되어 있고 제1도에서 곡선 3 도시한 알킬 그룹등의 원자 그룹을 나타낸다.Here, R represents an atomic group, such as an alkyl group, which is mixed by 0.01% by weight and shown by curve 3 in FIG.

즉, 푸른 형광물감 혼합 폴리탄산 수지의 평판에서, 보라빛-푸른 가시광선 파장 영역에 있는 440nm 파장에 해당하는 광 윈도우 A가 존재하고 판은 푸른색으로 착색된다. 푸른 안료(Anthraquinone Blue)가 혼합된 종래의 폴리탄산 수지상에 전체 가시 광선 파장 영역투과를 개선하는 것을 보인 것이고 그것은 제1도에서 곡선 1로 도시하였다.That is, in the flat plate of the blue fluorescent mixed polycarbonate resin, there is an optical window A corresponding to the 440 nm wavelength in the violet-blue visible light wavelength region and the plate is colored blue. It has been shown to improve the overall visible wavelength range transmission on a conventional polycarbonate resin mixed with anthraquinone blue, which is shown as curve 1 in FIG.

상기 언급한 실시예에서 상기 지적한 바와 같이 중량으로 0.01%정도 푸른 형광물감을 혼합하지만 본 발명에 의하면, 중량으로 0.001-0.1%정도 형광물감을 혼합시키면 만족할만한 결과를 얻을 수 있다.As mentioned above, in the above-mentioned embodiment, blue fluorescent dyes are mixed by 0.01% by weight. However, according to the present invention, satisfactory results can be obtained by mixing 0.001-0.1% fluorescent dyes by weight.

제2a도는 본 발명의 조명장치의 첫 번째 실시예에 따른 광안내의 투시도이고, 제2b도는 광안내 21의 단면도이다.FIG. 2A is a perspective view of the light guide according to the first embodiment of the lighting apparatus of the present invention, and FIG. 2B is a cross-sectional view of the light guide 21.

제2도로 언급하면, 광안내의 단면 형태는 평평하며, 형광물감 25는 투명수지로 이루어진 전체 광안내에 불균일하게 혼합되어 있다. 제2B도의 단면도로 알 수 있는 바와 같이, 텅스텐 램프 또는 LED 또는 형광 램프등의 광원으로부터 광 19은 형광물감 25와 충돌하고 거기에서 산란한다. 흰 페인트층, 알루미늄 박 또는 거친 표면등의 반사층이 광안내의 후측상 위에 형성된다면 실제 완벽하게 광이 반사되고 광도를 높게 하기 위하여 광안내 21의 표면으로부터 방사된다.Referring to FIG. 2, the cross-sectional shape of the light guide is flat, and the fluorescent paint 25 is unevenly mixed with the entire light guide made of transparent resin. As can be seen from the cross-sectional view of FIG. 2B, light 19 from a light source such as a tungsten lamp or LED or fluorescent lamp collides with and scatters fluorescent material 25 therein. If a reflective layer such as a white paint layer, aluminum foil or rough surface is formed on the rear side of the light guide, the light is actually reflected completely and emitted from the surface of the light guide 21 to increase the light intensity.

제3도 및 제4도는 반사도 변화 반사부가 제2도에 도시한 광안내의 반사층 23으로서 형성되는 실시예들을 도시한 투시도이다. 제3도에서 도시한 광안내에서 새김눈 41은 광 진행 방향과 직각인 광안내의 후면상에 반사부로서 형성된다. 새김눈 1은 광안내 21의 후면상에 산과 골을 교번적으로 제조함으로써, 그리고 광원 24의 반대측에 대하여 두 개의 인접 새김눈 사이의 간격을 더 좁게 함으로써 형성된다.3 and 4 are perspective views showing embodiments in which the reflectivity change reflecting portion is formed as the reflecting layer 23 of the light guide shown in FIG. In the light guide shown in FIG. 3, the notch 41 is formed as a reflector on the back surface of the light guide perpendicular to the light propagation direction. Indentation 1 is formed by alternating manufacture of peaks and valleys on the backside of light guide 21 and by narrowing the spacing between two adjacent indentations relative to the opposite side of light source 24.

따라서 광원 24와 밀접한 부분에서 광안내 내부로부터 반사된 빛의 양이 비교적 적고 조명측과 반대측에 빛이 방사되지만 광원 24로부터 멀리 떨어진 부분에서 광안내 내부로 반사된 광의 양은 비교적 증가된다. 따라서 광원으로부터 거리가 멀어지더라도 방사 표면으로부터 광의 양은 줄어들지 아니한다.Therefore, the amount of light reflected from the inside of the light guide in a portion close to the light source 24 is relatively small and the light is emitted on the opposite side to the illumination side, but the amount of light reflected into the light guide in a portion far from the light source 24 is relatively increased. Thus, the distance from the light source does not reduce the amount of light from the emitting surface.

제4도는 광반사 필름이 사용되는 본 발명의 또 다른 실시예를 설명한 투시도이다. 흰페인트 필름과 같은 불투명한 필름은 광안내 21의 후면에 코팅하거나 접착제를 사용하여 붙이는 이것은 광에 대한 필름의 양이 광원의 반대측으로 증가되도록 한다.4 is a perspective view illustrating another embodiment of the present invention in which a light reflecting film is used. An opaque film, such as a white paint film, is coated on the back of the light guide 21 or pasted with an adhesive, which causes the amount of film to light to increase to the opposite side of the light source.

즉, 광진행 방향과 직각인 길이가 증가된다. 비록 광원 24로부터 안내 21로 입사하는 광의 일부가 조명측과 반대측으로 방사되지만, 광안내 21의 내부 안으로 반사된 광의 양은 광원 24의 반대측으로 비교적 증가된다.That is, the length perpendicular to the light traveling direction is increased. Although a portion of the light incident from the light source 24 into the guide 21 is radiated to the opposite side to the illumination side, the amount of light reflected into the interior of the light guide 21 is relatively increased to the opposite side of the light source 24.

반사도 변화 반사층이 제3도 및 제4도에 도시한 바와 같이 배열되어 있다면, 광안내의 한측상의 배열된 광원으로부터 광은 표면으로 균일하게 방사되고 균일 평면 조명을 제공할 수 있다.Reflectivity Variation If the reflective layers are arranged as shown in FIGS. 3 and 4, light from the arranged light source on one side of the light guide can be uniformly radiated to the surface and provide uniform planar illumination.

제5도는 광안내 요소 32를 제2도에 도시한 바와 같은 구조를 갖는 광안내 21의 정면상에 배열하는 본 발명의 또 다른 실시예를 설명한 투시도이다. 광안내 요소 32는 광 방사면 43을 지닌 플레이트이고, 광안내 21로 입사하는 광에 대체로 수직 방향에서 광안내 21안으로 푸쉬되어서 입사광은 돌출면 43으로부터 우선적으로 방사된다. 방사광의 광도의 관점에서, 광안내 요소 32는 유기형광물감을 함유한 투명수지로 이루어져 있다.5 is a perspective view illustrating another embodiment of the invention in which the light guide element 32 is arranged on the front side of the light guide 21 having the structure as shown in FIG. The light guide element 32 is a plate with a light emitting surface 43 and is pushed into the light guide 21 in a direction generally perpendicular to the light incident on the light guide 21 so that incident light is preferentially emitted from the projecting surface 43. In terms of the intensity of the emitted light, the light guide element 32 consists of a transparent resin containing an organic phosphor.

제6도는 제2도에 도시한 바와 같은 구조를 지닌 광안내 21의 정면 영역에서 돌부를 형성하는 실시예를 설명한 것이고 그 영역에 조명을 요구하고, 여기에서 제6a도는 본 실시예의 투시도이고 제6b도는 단면도이다. 광원 24로부터 입사하는 광은 광안내 표면으로부터 방사되고, 돌부 34의 부분을 제외하고는 광안내 21의 표면이 불투명한 물질로 이루어진 마스크 36으로 덮혀져 있다면 조명을 요구하는 영역을 차지하는 돌부 34의 부분에서만 조명하게 된다.FIG. 6 illustrates an embodiment of forming a protrusion in the front region of the light guide 21 having the structure as shown in FIG. 2 and requires illumination in that region, where FIG. 6a is a perspective view of the present embodiment and FIG. 6b. Figure is a cross-sectional view. Light incident from the light source 24 is emitted from the light guiding surface and, except for the portion of the projection 34, the portion of the projection 34 which occupies the area requiring illumination if the surface of the light guide 21 is covered with a mask 36 made of an opaque material. Will only illuminate.

본 발명의 조명장치를 액정 텔레비젼 또는 액정 디스플레이에서 만들어져야 하는 후광으로서 사용할 수 있다.The illuminating device of the present invention can be used as a halo that should be made in a liquid crystal television or a liquid crystal display.

본 발명의 조명장치를 이루는 후광에서, 형광물감을 함유한 수지로 형성된 발광부 5는 투명수지로 이루어진 본체부 6에서 끼워넣게 되고 발광부 5의 양측상에 배열된 광원 7은 주변 가장자리를 따라 본체부 6에서 끼워넣게 된다. 본체부 6의 한 표면상에, 발광부에 대하여 광표면 7로부터 입사하는 광을 반사하는 본체부 6의 광원 삽입부의 주변 가장자리를 따라 반사 필름 8을 놓는다. 이 후광상에 배열된 확산 플레이트 11 및 확산 프레이트 11상에 배열된 액정 디스플레이 패널 12는 점선으로 지시되어 있다.In the halo constituting the lighting apparatus of the present invention, the light emitting portion 5 formed of a resin containing fluorescent paint is embedded in the main body portion 6 made of transparent resin, and the light source 7 arranged on both sides of the light emitting portion 5 has a main body along the peripheral edge thereof. It is embedded in part 6. On one surface of the body portion 6, the reflective film 8 is placed along the peripheral edge of the light source insertion portion of the body portion 6 which reflects light incident from the light surface 7 with respect to the light emitting portion. The diffuser plate 11 and the liquid crystal display panel 12 arranged on the diffuser plate 11 arranged on this backlight are indicated by dotted lines.

제8도는 상기 언급한 후광에서 광도 분포를 설명할 것이다. 즉 두께 5 mm, 폭 12mm, 길이 100mm 인 발광부 5의 길이방향 양측상에 서로 10mm 정도 떨어져서 텅스텐 램프를 배열하고 후광표면으로 방사된 광의 광도를 측정함으로써 얻어진 결과가 제8도에 도시되어져 있다.8 will explain the luminous intensity distribution in the halo mentioned above. That is, the result obtained by arranging tungsten lamps about 10 mm apart from each other in the longitudinal direction of the light emitting portion 5 having a thickness of 5 mm, a width of 12 mm, and a length of 100 mm and measuring the luminous intensity of light emitted to the back surface is shown in FIG.

제8도에 도시한 바와 같이, 각 광원이 1.2W의 스포트 광원이지만 두 광원이 밝다면 55±18cd/㎡의 광도를 얻고 이 광도는 후광으로서 사용된 EL(전자발광)의 광도(약50cd/㎡)보다 높다. 보통 적용상태에서 텅스텐 램프의 수명은 1000시간(h) 이상이고, 본 발명의 조명장치를 사용한다면 광도가 5000 시간의 절반 가량 감소된 EL요소의 수명보다 더 긴 수명을 지닌 후광을 제공할 수 있다.As shown in FIG. 8, each light source is a 1.2 W spot light source, but if both light sources are bright, a luminance of 55 ± 18 cd / m 2 is obtained, which is the luminance of the EL (electroluminescent) used as a halo (about 50 cd / M 2). In a typical application, the life of a tungsten lamp is more than 1000 hours (h), and using the lighting device of the present invention can provide a halo having a longer life than that of an EL element whose brightness is reduced by about half of 5000 hours. .
