Description
本發明涉及一種光源裝置。 The present invention relates to a light source device.
發光二極體(Light Emitting Diode，LED)是一種可將電流轉換成特定波長範圍的光電半導體元件。發光二極體以其亮度高、工作電壓低、功耗小、易與積體電路匹配、驅動簡單、壽命長等優點，從而可作為光源而廣泛應用於照明領域。 A Light Emitting Diode (LED) is an optoelectronic semiconductor component that converts current into a specific wavelength range. The light-emitting diode is widely used in the field of illumination because of its high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life.
發光二極體的一種典型的應用是製作成平面光源。然而，在製作時，普遍是將復數個發光二極體排列成陣列形狀而形成平面光源。這種做法無疑需要數量較多的發光二極體，不利於節省成本。 A typical application of a light-emitting diode is to make a planar light source. However, in production, it is common to arrange a plurality of light emitting diodes in an array shape to form a planar light source. This approach undoubtedly requires a large number of light-emitting diodes, which is not conducive to cost savings.
有鑒於此，有必要提供一種成本較低的光源裝置。 In view of this, it is necessary to provide a lower cost light source device.
一種光源裝置，包括：殼體，包括底蓋以及與底蓋相結合的頂蓋，底蓋與頂蓋之間形成有容置腔，頂蓋上形成有出光口；導光板，設置於殼體的容置腔內，所述導光板為長條狀，其包括相對設置的第一短邊與第二短邊，以及連接在第一短邊與第二短邊之間的第一長邊與第二長邊，任一長邊的長度大於任一短邊長度的兩倍； 擴散板，設置於導光板與頂蓋之間並覆蓋頂蓋上的出光口；第一光源模組與第二光源模組，設置於導光板的側面，第一光源模組的出光面面向第一短邊設置，第二光源模組的出光面面向第二短邊設置；以及驅動電源，設置於底蓋上且與第一光源模組與第二光源模組電連接。 A light source device includes: a housing, a bottom cover and a top cover combined with the bottom cover; a receiving cavity is formed between the bottom cover and the top cover, a light exit port is formed on the top cover; and the light guide plate is disposed on the housing In the accommodating cavity, the light guide plate is elongated, and includes a first short side and a second short side disposed opposite to each other, and a first long side connected between the first short side and the second short side The second long side, the length of either long side is greater than twice the length of either short side; a diffuser plate disposed between the light guide plate and the top cover and covering the light exit port on the top cover; the first light source module and the second light source module are disposed on a side of the light guide plate, and the light emitting surface of the first light source module faces a short side is disposed, the light emitting surface of the second light source module is disposed facing the second short side, and the driving power source is disposed on the bottom cover and electrically connected to the first light source module and the second light source module.
在上述光源裝置中，由於第一光源模組與第二光源模組設置於導光板的側面，其所發出的光線入射到導光板之後，從導光板的與擴散板相鄰的表面出射，然後經過擴散板與出光口出射到外界。上述結構僅需要數量較少的光源即能組成平面光源裝置，從而節省了成本。同時，由於第一光源模組與第二光源模組設置於導光板的短邊，從而進一步減少了光源的數量。 In the above light source device, since the first light source module and the second light source module are disposed on the side of the light guide plate, the light emitted by the first light source module and the second light source module are incident on the surface of the light guide plate adjacent to the diffusion plate after being incident on the light guide plate, and then After the diffusion plate and the light exit port are emitted to the outside. The above structure requires only a small number of light sources to form a planar light source device, thereby saving cost. At the same time, since the first light source module and the second light source module are disposed on the short side of the light guide plate, the number of the light sources is further reduced.

在上述光源裝置100中，由於第一光源模組40與第二光源模組50設置於導光板20的側面，其所發出的光線從側面入射到導光板20之後，從導光板20的與擴散板30相鄰的表面出射，然後經過擴散板30與出光口14出射到外界。即，上述結構僅需要數量較少的發 光二極體光源42、52即能組成平面光源裝置100，從而節省了成本。此外，由於第一光源模組40面嚮導光板20的第一短邊21設置，第二光源模組50面嚮導光板20的第二短邊22設置，且任一短邊21、22的長度小於任一長邊23、24的長度的一半，上述結構可進一步減少發光二極體光源42、52的數量。 In the light source device 100, since the first light source module 40 and the second light source module 50 are disposed on the side surface of the light guide plate 20, the light emitted from the light source plate 20 is incident from the side surface to the light guide plate 20, and diffused from the light guide plate 20 The adjacent surfaces of the plates 30 are emitted and then exit to the outside through the diffuser plate 30 and the light exit port 14. That is, the above structure only requires a small number of hair The photodiode light sources 42, 52 can constitute the planar light source device 100, thereby saving cost. In addition, since the first light source module 40 is disposed on the first short side 21 of the light guide plate 20, the second light source module 50 is disposed on the second short side 22 of the light guide plate 20, and the length of any short side 21, 22 is less than The above structure can further reduce the number of the light emitting diode light sources 42, 52 by half the length of any of the long sides 23, 24.
優選地，所述光源裝置100可進一步包括反射板70。所述反射板70設置於導光板20與底蓋11之間。所述反射板反射第一光源模組40與第二光源模組50所發出的光線，從而使其從導光板20的與擴散板30相鄰的表面出射。在本實施例中，所述反射板70由金屬材料製成，其製作材料包括銅、鋁、鎳、銀、鐵、鈀、鋅或其合金。 Preferably, the light source device 100 may further include a reflective plate 70. The reflector 70 is disposed between the light guide plate 20 and the bottom cover 11 . The reflector reflects the light emitted by the first light source module 40 and the second light source module 50 so as to be emitted from a surface of the light guide plate 20 adjacent to the diffusion plate 30. In the present embodiment, the reflecting plate 70 is made of a metal material, and the material thereof is made of copper, aluminum, nickel, silver, iron, palladium, zinc or an alloy thereof.
圖5為本發明第二實施例提供的光源裝置200。該光源裝置200與第一實施例所提供的光源裝置100的結構相類似。與第一實施例不同的是，所述光源裝置200還包括一增亮膜80。所述增亮膜80設置於導光板20與擴散板30之間。所述增亮膜80沿導光板20的延伸方向劃分為復數個區域，且該復數個區域的面積從導光板20的中間往兩邊逐漸減小。在本實施例中，增亮膜80中設置有等間距的間隙81以將增亮膜80劃分成復數個區域。由於增亮膜80可破壞光線在導光板20中的全反射條件，從而有效地從導光板20的與擴散板30相鄰的表面出射。因此，由於導光板20的中間位置的增亮膜80面積較大，而導光板20邊緣位置的增亮膜80面積較小，上述結構可改善當導光板20具有較大的長度時，導光板20中間的光線較弱的問題，從而使光源裝置200的出光較為均勻。根據需要，亦可將增亮膜80中設置復數個開孔，且開孔的孔徑大小從導光板 20的中間往兩邊逐漸增大。這種結構同樣可使到導光板20的中間位置的增亮膜80面積較大，邊緣位置的增亮膜80面積較小，從而使出光均勻。 FIG. 5 is a light source device 200 according to a second embodiment of the present invention. The light source device 200 is similar in structure to the light source device 100 provided by the first embodiment. Different from the first embodiment, the light source device 200 further includes a brightness enhancement film 80. The brightness enhancement film 80 is disposed between the light guide plate 20 and the diffusion plate 30. The brightness enhancement film 80 is divided into a plurality of regions along the extending direction of the light guide plate 20, and the area of the plurality of regions gradually decreases from the middle of the light guide plate 20 to both sides. In the present embodiment, the brightness enhancement film 80 is provided with equally spaced gaps 81 to divide the brightness enhancement film 80 into a plurality of regions. Since the brightness enhancement film 80 can destroy the total reflection condition of the light in the light guide plate 20, it is efficiently emitted from the surface of the light guide plate 20 adjacent to the diffusion plate 30. Therefore, since the area of the brightness enhancement film 80 at the intermediate position of the light guide plate 20 is large, and the area of the brightness enhancement film 80 at the edge position of the light guide plate 20 is small, the above structure can improve the light guide plate when the light guide plate 20 has a large length. The problem of weak light in the middle of 20 makes the light output of the light source device 200 relatively uniform. If necessary, a plurality of openings may be disposed in the brightness enhancing film 80, and the aperture size of the opening is from the light guide plate. The middle of 20 gradually increases toward both sides. This structure also makes it possible to increase the area of the brightness enhancement film 80 to the intermediate position of the light guide plate 20, and to have a small area of the brightness enhancement film 80 at the edge position, thereby making the light output uniform.
