본 발명은 광원모듈에 관한 것으로, 보다 상세하게는 LED광원과 도광판이 일체로 형성되는 LED광원모듈에 관한 것이다.The present invention relates to a light source module, and more particularly, to an LED light source module in which the LED light source and the light guide plate are integrally formed.

광원모듈은 액정표시장치(Liquid Crystal Display)를 조명하기 위한 것으로, 조명방식에 따라 광원의 배면에 확산판을 배치하여 광원으로부터 빛을 반사, 확산시켜 균일하게 평면 광원으로 하는 직하방식(반사판방식), 투명 도광체의 측단면에 광원을 배치하고 도광체의 한면을 반사, 확산 처리하여 빛을 다중 반사시켜 면광원하는 도광체방식 및 면상광원을 그대로 사용하는 면광원방식이 있다. 이 중에서, 도광체방식이 박형화에 강하고 휘도의 균일성이 좋아 널리 사용되고 있다.The light source module is used to illuminate a liquid crystal display, and a direct diffusion method is provided in which a diffuser plate is disposed on the rear surface of the light source according to an illumination method to reflect and diffuse light from the light source to make a flat light source. For example, there is a light guide method in which a light source is disposed on a side surface of the transparent light guide, and one surface of the light guide is reflected and diffused to multi-reflect light to use a surface light source and a surface light source that uses a surface light source as it is. Among them, the light guide system is widely used because it is strong in thinning and has good luminance uniformity.

이와 같은 도광체방식의 광원모듈의 일례로 일본특허 제3549087호의 「도광체, 사이드라이트형 면광원장치 및 액정표시장치」를 들 수 있으며, 해당특허의 도광체가 도 8 및 도 9에 도시되어 있다.An example of such a light guide module of the light guide type includes "light guide body, side light type surface light source device and liquid crystal display device" of Japanese Patent No. 3549087, and the light guide of the patent is shown in FIGS. 8 and 9. .

도 8에 도시된 바와 같이, 도광체는 도광판(11)과 1차광원(12)으로 구성되어 있다.As shown in FIG. 8, the light guide is composed of a light guide plate 11 and a primary light source 12.

도광판(11)은 빛이 입사되는 입사면(11a)과 빛이 산란되어 면상태로 출사되는 출사면(11b)를 가지며, 입사면(11a)에는 한 쌍의 사면(18a,18b)에 의해 연장되는 돌기가 길이방향으로 반복적으로 형성되어 있다.The light guide plate 11 has an incident surface 11a on which light is incident and an exit surface 11b on which light is scattered and exits in a plane state, and is extended by a pair of slopes 18a and 18b on the entrance surface 11a. Protrusions are formed repeatedly in the longitudinal direction.

1차광원(12)은 봉상부재(16)와 점광원(17)으로 구성되며, 도광판(11)의 입사면(11a)과 마주하게 일정 간격을 두고 이격되게 배치되어 있다.The primary light source 12 is composed of the rod-shaped member 16 and the point light source 17, and is spaced apart from each other at regular intervals to face the incident surface 11a of the light guide plate 11.

봉상부재(16)는 도광판(11)의 출사면(11b)와 거의 평행한 면에 위치하고, 선단이 잘려진 쐐기형상으로 형성되어 있다. 또한, 봉상부재(16)는 도광판(11)의 입사면(11a)와 마주하는 면에 출사면(11b)이 형성되어 있다.The rod-shaped member 16 is located on a surface substantially parallel to the exit surface 11b of the light guide plate 11, and is formed in a wedge shape with its tip cut off. In addition, the rod-shaped member 16 has an emission surface 11b formed on a surface of the light guide plate 11 that faces the incident surface 11a.

점광원(17)은 발광다이오드로 구성되고, 출사면이 투명접착제에 의해 봉상부재(16)의 단면(16a)에 접착되어 있다.The point light source 17 is composed of a light emitting diode, and the emission surface is adhered to the end face 16a of the rod-shaped member 16 by a transparent adhesive.

이와 달리, 도 9에 도시된 도광체는 도광판(11)과 3개의 봉상부재(16)로 구성되어 있다.In contrast, the light guide shown in FIG. 9 is composed of a light guide plate 11 and three rod-shaped members 16.

도광판(11)의 압사면에는 사면(18a,18b)가 형성되어 있다.Slopes 18a and 18b are formed on the inclined surface of the light guide plate 11.

봉상부재(16)는 도 8의 봉상부재(16)를 순차적으로 적층하고, 각 봉상부재 (16)에 녹색, 적색 및 청색의 점광원(17G,17R,17B)을 배치하여 형성된다. 이때, 봉상부재(16)는 출사면과 이면이 서로 밀접하도록 적층 및 배치된다.The rod-shaped member 16 is formed by sequentially stacking the rod-shaped members 16 of FIG. 8 and arranging green, red, and blue point light sources 17G, 17R, and 17B on each rod-shaped member 16. At this time, the rod-shaped member 16 is stacked and arranged so that the exit surface and the back surface are in close contact with each other.

여기서, 점광원(17G,17R,17B)은 발광다이오드로 구성되고, 출사면이 투명접착제에 의해 봉상부재(16)의 단면(16a)에 접착되어 있다.Here, the point light sources 17G, 17R, and 17B are composed of light emitting diodes, and the emission surface is adhered to the end face 16a of the rod-shaped member 16 by a transparent adhesive.

그러나, 상술한 구성을 갖는 종래기술의 도광체는 점광원에서 방출되는 빛을 혼합하여 백색빛을 충분하게 생성하기 위하여 봉상부재와 도광판이 간격을 두고 이격되기 형성되기 때문에 도광체의 크기가 커지고, 심지어, 도 9와 같이 3개의 봉상부재를 사용하는 경우에는 도광체의 크기가 더욱 커지는 문제가 있었다.However, the light guide of the prior art having the above-described configuration increases the size of the light guide because the rod-shaped member and the light guide plate are formed to be spaced apart at intervals to sufficiently generate white light by mixing the light emitted from the point light source. Even when using three rod-like members as shown in FIG. 9, there is a problem that the size of the light guide is further increased.

본 발명은 상술한 종래기술의 문제점을 해결하기 위하여 창안한 것이다. 본 발명의 목적은 빛을 혼합하는 데 필요한 공간을 도광판의 내부에 일체로 형성함으로써 도광체의 크기를 줄일 수 있는 광원모듈을 제공하는 것이다.The present invention has been made to solve the above-mentioned problems of the prior art.

하우징(111)은 일면에 개방구(112)가 형성되어 일면만이 개방되고 나머지 면들은 모두 폐쇄된다. 따라서, 각 다이오드에서 방출되는 빛을 한 쪽으로 모아서 외부로 출사할 수 있다.The housing 111 has an opening 112 formed on one surface thereof so that only one surface is opened and the remaining surfaces are all closed. Therefore, the light emitted from each diode can be collected to one side and emitted to the outside.

또한, 하우징(111)은 내부의 소정 위치, 바람직하게는 중앙에 3개의 발광다이오드, 즉 LR, LG 및 LB로 도시한 적색, 녹색 및 청색의 빛을 발산하는 발광다이오드가 일정간격, 즉 L의 간격을 두고 나란히 배치된다. 여기서, 발광다이오드 간의 간격 L을 개별패키지에서의 발광다이오드 간의 간격인 수 ㎜ 보다 아주 작게 수백 ㎛ 정도로 설치함으로써 통상적으로 색혼합에 필요한 LED광원과 도광판 사이의 거리가 크게 줄어 들게 되고 또한 색혼합에 필요한 거리를 줄이기 위해 빛의 경사각을 확대하는 데 별도로 요구되었던 렌즈 또는 확산수단이 요구되지 않는다.In addition, the housing 111 has a light emitting diode emitting red, green, and blue light at predetermined intervals, preferably three light emitting diodes, ie, L R , L G, and L B in the center. That is, they are arranged side by side at intervals of L. Here, the distance L between the light emitting diodes is set to about several hundred micrometers, which is much smaller than the number of mm, which is the distance between the light emitting diodes in individual packages, and the distance between the LED light source and the light guide plate, which is usually required for color mixing, is greatly reduced, and necessary for color mixing. There is no need for a lens or diffuser that was required separately to enlarge the angle of inclination of the light to reduce the distance.

또한, 각 발광다이오드(LR, LG, LB)에서 방출되는 빛은 하우징(111) 내에 충진된 매질 내에서 운동하면서 어느 정도 색혼합이 된 상태로 외부로 방출되기 때문에 LED광원(110)의 외부에서 적색, 녹색 및 청색의 3가지 파장의 색혼합에 필요한 공간을 줄일 수 있다.In addition, since the light emitted from each light emitting diode (L R , L G , L B ) is emitted to the outside in a state of color mixing while moving in a medium filled in the housing 111, the LED light source 110. The space required for color mixing of the three wavelengths of red, green, and blue can be reduced outside of.

Facing the reflection plate 123 is installed. At this time, the reflecting plate 123 is installed so that the end is not connected to the color mixing member 120 or the light guide plate 130, so that the opening 121 is formed in the color mixing member 120, the mixing in the color mixing member 120 The light proceeds to the light guide plate 130 only through the opening 121.
