Description of the Invention: [Technical Field] The present invention relates to a light source module, and more particularly to a line light source module. [Prior Art] Compared with the conventional light bulb, the light-emitting diode package assembled by the light-emitting diode chip has the characteristics of small volume, long light-emitting life, low power consumption, anhydrous silver π dyeing, and the like, Increased luminous efficiency of polar body wafers In some areas, optical monolithic packages have gradually replaced fluorescent lamps and incandescent 2 bubbles for a wide range of applications such as scanner light sources, backlights for liquid crystal displays, automotive instrument panel light sources, and traffic sources. Referring to Fig. 1, a light-emitting diode package 1 assembled from a light-emitting diode chip currently comprises a clamshell 11, a light-emitting diode chip 12, and a filling material 13. The package U is substantially a cube and includes a (four) (1), a peripheral wall 112 extending upwardly and outwardly from a periphery of the bottom wall 111, a bowl-shaped accommodation space 113 defined by the bottom wall (1): the peripheral wall, and a conductive line 114 formed on the bottom wall (1); the light emitting diode wafer η is electrically connected to the conductive line 114 of the package U to be mounted on the bottom wall (1) of the package U; the package knee 13 It is transparent and filled in the accommodating space (1), and covers the illuminating diode chip 12 to isolate the illuminating diode chip from the outside, thereby avoiding damage caused by external moisture or the like. When the light-emitting diode wafer 12 emits light from the outside through the conductive line 114, the light emitted by the light-emitting diode 12 is directly passed through the package rubber 13 and then emitted outward. And a portion is changed in the traveling direction after being reflected by the inner surface of the peripheral wall 112 of the encapsulating shell, and is also outwardly ejected through the encapsulating material 13. The current LED package i can achieve the purpose of providing a light source. However, the main disadvantage is that the volume of the package cannot be reduced, resulting in the inability of the component to cope with the trend of light and thin electronic products. In addition, the light is borrowing from the wall. During the reflection process of the inner surface of H2, part of the light is absorbed and converted into heat', which causes the actual working life of the Wei diode wafer 12 to be shortened, which also causes the light-emitting diode wafer 12 to emit light (four) unstable. In contrast to FIG. 2, although the above-mentioned light-emitting diode package i has the above-mentioned disadvantages, but compared with the current types of artificial light sources, there is a significant improvement in both volume and power consumption. Therefore, the related art has proposed to apply the above (4) optical diode packages, which are arranged neatly arranged on the printed circuit board 200 to form the line light source module 3, which is used to replace the conventional cold cathode lamp 7 and hope to reduce the volume of the backlight module. Power consumption, and the purpose of improving the brightness of the light. However, the line light source module 3 assembled directly using the light emitting diode package is still limited by the body of the light emitting diode package, and the electronic product is further compatible with the electronic product. Volume reduction, application areas are still limited. Furthermore, since the linear light field formed by the line light source module 3 is connected to each other by the light field emitted from each of the light emitting diode packages, it is inevitable that due to the blocking of the package 11 Between the adjacent light fields, the brightness of the light 201104133 is weak, and the linear light field is formed with the phenomenon that the bright and dark regions are interlaced, instead of the linear light with uniform brightness and continuous, and such light and dark interlaced linear light And it is not conducive to the subsequent practical application. In addition, when the light source module 3 is combined with the light guide plate to form the backlight module, the light emitted by each of the light-emitting diode chips 12 passes through the package adhesive 13 in the process of light travel. Air, then enter the light guide plate. 'The refractive index is different due to package riding 13, air, and light guide (4)
,因此會有部分的光無法耦合進入導光板中,造成光量的損 失。 因此,如何改善目前應用發光二極體晶片13所成之發 光二極體封裝件1,以及應用此等發^^㈣封裝件i形成 之線光源模組3,使其能在體積、散熱上有大幅的提升、形 成之光場有實際應用的價值,甚至應用作為背光模組時可 以減少光量的損失,都有待學界與業界共同集思廣益。 【發明内容】Therefore, part of the light cannot be coupled into the light guide plate, causing loss of light amount. Therefore, how to improve the light-emitting diode package 1 formed by the current application of the light-emitting diode chip 13 and the line light source module 3 formed by using the above-mentioned four-component package i can be used for volume and heat dissipation. There is a substantial increase, the formation of the light field has practical application value, and even when used as a backlight module can reduce the loss of light, it is waiting for the academic community and the industry to brainstorm together.

The heat conduction is fast and the volume is. Therefore, the ultra-thin line light source module of the invention comprises a board, a plurality of light-emitting diode chips, and a package glue. The seat plate is a base layer which is flexible and composed of a material having a high heat transfer coefficient, an insulating layer formed on the base layer and insulated, and a conductive material disposed on the insulating layer, the insulating layer is composed of It is composed of an oxide formed of a material constituting the underlayer. A plurality of light-emitting diode chips are electrically connected to the conductive line and are mounted on the 201104133 seat board and emit light when powered by the conductive line. The transparent package coffin is formed on the seat plate and covers the light emitting diode wafer unit. The utility model has the advantages that the light-emitting diode wafer is directly disposed on a seat plate which can be wound and mainly composed of a base layer capable of rapid heat conduction, and the heat generated accompanying the light-emitting can be quickly guided away to improve the light-emitting stability and the light-emitting stability. The actual working life, while greatly reducing the volume, can increase the application field by flexing characteristics. In addition, the encapsulant can be shaped by subsequent light guiding and homogenizing, thereby reducing light loss and increasing application efficiency. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to Figure 3, a preferred embodiment of an ultra-thin line source module 4 of the present invention comprises a board 41, a plurality of LED chips 42, and a package of adhesive 43. The seat plate 41 is in the form of a long strip, and comprises a base layer which is bendable and made of a material having a high thermal conductivity, an insulating layer 412 formed on the base layer and insulated, and a layer disposed on the insulating layer The conductive line 413 on the 412, the thinner the thickness of the base layer 411 is better, but when the thickness is too thin, the bearing capacity is insufficient. (4) When the problem is too thick, the main purpose of the invention is to lose the ultra-thinness and the path of heat dissipation is changed. Long and heat-dissipating problems occur, so 201104133 is best at 50 5〇〇/zm and is selected from alloys such as Ilu, steel, recorded, turned, steel, silver, etc., and/or alloys of these metals. The insulating layer 412 is made of an oxide formed of a material constituting the base layer 411, and has a thickness of 0.1 to 1 / zm, so that the overall thickness of the seat plate 41 is not more than 501#m, so it can be moderately flexed according to the application, and also has excellent heat dissipation performance; more specifically, the seat plate 41 is first selected from, for example, a very thin aluminum plate after a moderate oxidation treatment. Forming an aluminum oxide layer on the surface, at this time, oxidizing The layer is the insulating layer 412, and the unoxidized structure is the base layer 411. Thereafter, a metal crucible of a predetermined shape and thickness is disposed on the insulating layer 412 as the conductive line 413, thereby completing the I of the integral seat plate 41. The seat plate 41 can also be selected from, for example, an extremely thin aluminum plate as the base layer 411, and then the physical layer or the chemical plating film is sequentially formed to form the insulating layer 412 and the conductive line 413. Since the manufacturing process is not the focus of the present invention. Therefore, no more details are given here. The LED chips 42 are generally fabricated from the wafer after processing, and are electrically connected to the conductive lines 4丨3. It is also on the seat plate 41 and emits light when it is supplied via the conductive lines 413. The transparent package material 43 is formed on the seat plate 41, and the light-emitting diode chip 42 and the conductive line '' are shielded from the surface of the seat plate 41 for blocking, and the external moisture and the like are contaminated. Diode 曰曰曰# 42, It is worth mentioning that the constituent material of the encapsulating material 43 is curable after curing, and is used for the subsequent application of the flexor of the seat plate 41, or the thickness is extremely thin. Without affecting the overall flex %, in addition, 'the three-dimensional shape can be changed differently with the application of the subsequent guide 201104133 light and the uniform light; in this example, the constituent material of the encapsulating material 43 can be selected, for example, from Acrylic material, cut material. When the external power is supplied through the conductive lines 413, the light emitting diodes 42 can emit light emitted by the light emitting diodes 42 after being passed through the package rubber; and due to the light emitting: the polar body wafer 42 is directly The package material 43 is disposed on the seat plate 41, and the package material 43 is coated with the light-emitting diode chips 42 in a continuous predetermined three-dimensional shape. Therefore, the light emitted by the light-emitting diode chips 42 directly passes through the package rubber. 43. The linear light field formed by the outer surface of the package adhesive 43 is a linear light field with continuous brightness and is not like the existing line light source module 3, due to the single light emitting diode package. The package case 11 of the piece 1 is separated, and there is a phenomenon that the bright 'dark area is staggered. In addition, since the seat plate 41 is mainly made of a material having a high heat transfer coefficient, such as aluminum, copper, nickel, molybdenum, steel, silver, etc. The metal or the alloy is formed, and the overall thickness is extremely thin. Therefore, the waste heat generated by the light-emitting diodes 42 can be directly led out through the insulating layer 412 and the base layer 411 of the seat plate 41 having a very small thickness. And can be extended The actual service life of the ultra-thin line light source module 4 of the present invention improves the stability of the illumination and the uniformity of the sentence. Also, since the overall thickness of the seat plate 41 is not more than 5〇1#m, the thin film is grown, even if Taking into account the maximum thickness of the LED wafer 42 and the encapsulant 43 , the overall thickness is still extremely thin, and compared with the current line source module, the volume is greatly reduced, and thus the invention is super When the thin light-emitting diode light source module 4 is actually used in electronic products, it really helps the 201104133 2 sub-product (four) type and lightweight design; the system is the flexible function of the "s" of the seat plate, so it is more visible. It is actually necessary to make a variety of cooperation* and can be applied to the currently developing flexible liquid crystal display and electronic paper for use as a light source. In addition, if the application of the (4) super-twisted light source module 4" light guide plate with σ assembled into a backlight for liquid crystal display, the refractive index of the sealing material 43 can also be selected to be the same as the light guide plate. And in conjunction with directly contacting Fengjing 43 to the light guide plate, for example, opening a groove of the ultra-thin line light source module 4 of the present invention on the light incident surface of the light guide plate, and the ultrathin line light source module of the present invention The group 4 is assembled with the light guide plate, so that not only the overall volume of the back rice source can be reduced, but also the light emitted by the light-emitting body day 42 is passed through the encapsulating material 43 in terms of the traveling path of the light. After that, it directly consumes into the light guide plate with the refractive index and the sealing material 43, so that almost no light loss is generated, and the brightness and the uniformity of the backlight can be improved, and the invention is ultra-thin. The linear light source mode and the group 4 are provided by directly arranging the light-emitting diode wafer 42 on the flexible and rapidly heat-conductive seat plate ,, so that the light-emitting diode chip 42 can be quickly self-supporting when it emits light. The plate 41 is outwardly led out, and in addition, is also thinned by the seat plate 41 The sheet-like design can reduce the overall volume and reduce the space occupied by the electronic product. At the same time, since the ultra-thin line light source module 4 of the present invention is flexible, it can be applied to, for example, a flexible liquid crystal display, an electronic device. The paper is used as a backlight. In addition, the package material of the ultra-thin line light source module 4 of the present invention can be formed according to the application of the subsequent light guiding and the homogenizing light, thereby greatly reducing the optical loss of the shell 201104133 and increasing the application. The field performance 'does improve the hot title and volume problem of the conventional line source module i' to achieve the object of the present invention.
