New Description: [New Technology Field] This paper is about a light source device and its application, especially regarding a strip light source device that produces directional light and its application. [Prior Art] 'Liquid crystal display (LCD) has the advantages of low power consumption, low radiation, thin thickness, and light reset. It has gradually replaced the traditional CRT display and has become a widely used flat panel display. The liquid crystal display itself is a non-self-illuminating display device, which must be able to achieve the display effect by means of an external light source. [The current liquid crystal display uses a backlight module (Backlight) as an external light source. Affects the quality and quantity of the display of the liquid crystal display. The backlight module is composed of a light source, a light guide plate, a diffuser film, a prism sheet, a Ref lec_tor, and the like, and the light source is in the backlight module. 'The position of the inner display can be divided into Side-edge type and Direct type*. The side-light source is set on the side of the backlight module. After the light enters the light guide from the side, The light is turned into the LCD liquid crystal display through the reflective strips specially designed in the light guide plate. The liquid crystal display using the side light source is mostly applied to small portable electronic devices such as notebook computers and personal digital assistants; The light source is disposed under the liquid crystal panel, and the light is directly or indirectly reflected to the upper optical film to enhance the brightness. The liquid crystal display using the direct light source is mostly applied to a large-sized display such as a liquid 5 M350730 crystal television. The backlight module generally uses a cold cathode fluorescent lamp (c〇ld cathode flU0rescent iamp, CCFL) as a light source, and the cold cathode fluorescent lamp is a slender sealed glass tube filled with an inert gas and using mercury as a discharge medium. When a high voltage is applied to the light tube, the inert gas generates ultraviolet light and is excited by the fluorescent material on the inner wall of the tube to emit visible light. The cold cathode glory tube has low cost and high efficiency (light wheel output and input electric power ratio). Advantages, but the cold cathode fluorescent tube needs a higher driving voltage' and the cold cathode fluorescent tube has a temperature that is not conducive to starting at a low temperature, and the mercury contained in the cold cathode fluorescent tube will be environmentally friendly. And human body, harm" Therefore, how to obtain a light source to replace the cold cathode fluorescent tube, manufacturers work hard to research and develop the subject. In recent years, the technology of light-emitting diodes has become more and more mature, and the light-emitting bodies have the characteristics of low driving voltage, high life and high power saving, and can be fabricated into miniaturization or arrays in accordance with application requirements. Composition, such as the payment of money, billboards, flashlights, various electronic products, indicating that the illumination can be seen in the application of the light-emitting two-body, making the light-emitting diode a wide source of light, thus replacing the cold-cathode fluorescent tube with a light-emitting diode. That is = the main research direction of the ^ optical module Wei business. US patent us 5727862 _328, US6〇fJS Μ·, fat 5883684, US & US 6〇65845, us 6139163, 邶 63753 milk

The light emitted should also be like a cold cathode fluorescent tube backlight module. The light emitted by the LED is driven into a light guide plate. The light guide plate is about a square plate that matches the area of the liquid crystal panel. Wedge or • Plate), the light is reflected by the reflector to the light above the light guide plate. The light guide plate - with optical film (diffusion film, enamel film, brightness enhancement film, etc.), is transmitted through the optical film to obtain a uniform surface light source. In the aforementioned U.S. patent, whether it is a side light type or a direct type, a plurality of light emitting diodes must be used, and the point light source is coupled into one side light source, and thus, the surface light source cannot be uniformly distributed; Variations in the intensity and distribution of the illuminance between the polar bodies. Generally, the design of the backlight module can only be considered for light uniformity, and it is impossible to balance the requirements of light distribution, light directivity, light extraction efficiency, polarization, etc., so that an additional number of diffusion films (such as a diffusion film) are required. Dif fuser ), φ ( Prism shee〇, Enhance sheet, Reflector' (Reflector) and other optical films to adjust their optical characteristics to meet the needs of liquid crystal panels. The backlight of the liquid crystal panel adopts a direct-type backlight-torque group, which requires hundreds or even thousands of high-density matrix arrays of light-emitting diodes to achieve uniformity within a short distance. The number of light-emitting diodes is higher. Many, although the uniformity of light output can be improved, the manufacturing cost will also increase, and the point light source is coupled through the light guide plate and the multilayer optical film multiple times, which will cause serious light loss. Loss, relatively increase the power consumption of the backlight module, therefore, the application of the light-emitting diode to the backlight module, there are still many problems to be solved by the M350730. The linear linear light source causes the light to be multi-/-light diode The array-shaped guide disc--the defect of sentence uniformity is proposed by a cylindrical transparent wire (4), the linear light guide is placed, the cylindrical guide is covered by the shot, and the part of the side of the illuminator is provided with light emission. The light is again an end face of the cylindrical guide member, and the inside of the cylindrical guide member inside the guide member of the illuminator, when the light is incident on the light scattering portion of the cylinder: = total reflection, when the light is partially formed, the light is formed The fine illumination Hi m whose angle is smaller than the critical angle. The line disclosed in the patent US 5,969,343 causes the incident light scattering portion of the cow to scatter the total reflected light, and the radiation is applied in the application; and the linearity in the main scanning direction is obtained. The central, the red female, the sweep can improve the problem of the traditional scanner array, and the private linear illumination f has directivity == in the qi, thus making the emitted light not ', , ",, as Backlight source of liquid crystal panel.

A plurality of light guides (5) made of resin or glass are arranged in parallel with each other in the frame. One side of the frame is provided with a point light source, and the inner bottom surface M350730 of the frame body is provided with a reflecting plate, and the light emitted from the light source unit (the point light source and the light guiding rod) is reflected toward the light emitting surface of the frame body; and the light source unit will The light emitted by the point light source is incident on the light guide bar from the end face, and the light incident on the light guide bar is refracted in the mountain, because the angle between the exit surface of the light guide bar becomes a critical angle or more = the total reflection surface of the exit surface is oriented The light guiding rod propagates to the end surface, and the angle between the light incident on the light guiding rod and the emitting surface of the light guiding rod is equal to or less than a critical angle, and is not totally reflected on the emitting surface of the light guiding rod, but is emitted near the point light source. The light of the face increases. The disclosed planar light source device uses a plurality of light guiding rods and a point light source as a light source unit, and the light emitted by the light source unit is reflected to the light emitting surface of the frame through the lower reflecting plate, and the patent may provide a relatively uniform light, but The design of the frame and the reflector is to increase the volume of the backlight module; further, the light guide bar only refers to the angle between the incident light and the exit surface being below the critical angle, and not at the exit surface of the light guide. The reflection ' does not suggest how to obtain uniform or directional light, and therefore, it is still impossible to realize a backlight source as a liquid crystal panel. [New content] The purpose of this creation is to overcome the drawbacks of the prior art and to provide a strip light source generating device having directivity and uniform distribution. The purpose of the present invention is achieved by the following technical solutions: including at least one light source and a light guide body, the light guide body is a cylindrical body made of a light transmissive material, wherein the light guide body surface is provided There is at least one diffusing strip, and the other side of the diffusing strip is a circular arc emitting surface; the light guiding body-end surface is covered with a reflecting 臈 and is defined as a reflecting surface 'oppositing end is incident M350730 plane' The light source is disposed on the incident surface of the light guide. The light generated by the illuminating source enters the inside of the light guide body from the incident surface and is totally reflected, and the light is continuously totally reflected inside the light guide body, when a certain continuous reflection light is incident on the diffusing strip, A ^ line is scattered into a plurality of scattered rays directed at a plurality of angles, and the scattered light is incident on the exit surface of the arc, and the exit surface of the arc causes the scattered light to be refracted toward the diffusing strip to scatter the light. The convergence is emitted outside the light guide, which becomes a strip light source with directivity and uniform distribution. A preferred example is as follows: The reflective film is a specular reflection film. The reflecting surface is also provided with a light source. The diffusing strip has an axial grating in the form of fine stripes. The diffusing strip has a sagittal grating in the form of fine stripes. The diffusing strip is discontinuous in a regular or irregular discontinuity. The surface of the light guide body is provided with two diffusing strips corresponding to the normal line and having the same angle. The light generated by the light source is totally reflected inside the light guide body, and the light is incident on the pair of diffused light. The strips are staggered with each other, and the scattered light is refracted through the light exiting surface to converge and stagger the light. The strip light source generating device of the present invention applies a point light source into the light guide body for total reflection, and the light is continuously totally reflected in the light guide body without loss of luminous flux. 'The total reflected light is repeatedly hit on the diffusing strip and passes through The light-emitting surface of the arc of the light guide body refracts and condenses the light to generate a directional light source with uniformity and uniform distribution. This creation is actually applied to the backlight source of the liquid crystal panel. A plurality of strip-shaped M350730 light sources are combined side by side to form a surface light source, which can provide a uniform and uniform directional light. Thus, an optical film such as a diffusion film or a cymbal film can be disposed. According to the same size LCD panel, you can choose the light guide body of the same length. Because the light loss is low, the longer light guide body can also obtain the line source of the distribution hook. The bias of the ray light increases the efficiency of light entering the liquid crystal panel, making the pickup more suitable for large-sized liquid crystal panels. The creation of the liquid crystal display backlight module light source can significantly improve the display quality, high brightness and high uniformity of the liquid crystal display. The strip light source generating device of the present invention may preferably be a backlight source of the L曰曰 display, but is not limited to being a backlight source of the liquid crystal display, such as an indoor and outdoor illumination source, a vehicle light source, or the like. [Embodiment] The present invention will be further described below in conjunction with the drawings and embodiments. Embodiment 1 Referring to the first and second figures, the light source generating device 30 of the present embodiment is composed of a light guiding body 10 and an illuminating source 20; the light guiding body 10 is a cylinder made of a transparent material, wherein the transparent material It is a material such as p〇l ymethy 1 methacrylate (PMMA) or glass. One end face of the light guide body is defined as the incident face l〇a, and the other opposite end face is defined as the reflective face 1〇b, and the reflection is The surface 10b is covered with a reflective film 11. When the light is incident on the light guide body 1 , the light having an incident angle greater than the critical angle will be totally reflected by the loss of the luminous flux, and the light will also be incident on the reflective film u of the reflective surface 10b. The reflection, therefore, 11 M350730 evenly floods the light guide body light continuously in the light guide body ίο total reflection, 10 inside. j is light-guided, on the circumferential surface of 10, along a direction parallel to the direction of the light guide body 1. Further, there is a radial strip 12, the diffusing strip 12 is perpendicular to the normal of the light guiding body 10, and the diffusing strip 12 is directly printed with a high-dispersion light source material such as a cerium oxide (Si〇2) or a titanium dioxide (7) (6). Applying on the circumferential surface of the light guide body or arranging a high divergent light source material on the surface of the light guide body 1 or forming a fine strip grating structure on the surface of the light guide body 10 (τ (4)), can. In order to realize the directivity and distribution of the strip light source, #' and the strip 12 is best coated with the printing paint directly on the light guiding body 1Q, and the diffusing strip can be controlled by the coating method. The number and width of 12 are obtained to obtain the desired light distribution of the directional strip light source. The other side surface is defined as a surface of the cylindrical body which is disposed on the light-emitting surface 13 of the light guide body 10 with respect to the diffusing strip 12, and the light-emitting surface 13 is formed into a circular arc surface. The light source 20 is a self-illuminating reading such as a light-emitting diode that emits light. The light source 20 is disposed on the light guide body 1〇# incident surface gamma, and is closely attached or embedded in the light guide body 1G. The shirt may also have a gap with the human face-to-face shirt to achieve the desired optical requirements according to the actual "structural relationship." As shown in the third, fourth, and fifth figures, the light source generating device 30, the light source 20 When the light from the incident surface 10a is emitted into the light guide body 1 ,, when the light is transmitted in the light guide body, the angle of the person of the New Zealand is greater than the critical lining, and the light is completely unable to be emitted from the light guide body 1G, so that the light is lightly connected. The inner 12 M350730 of the guide H) is totally reflected, so that the light is evenly filled inside the light guide body 10 (as shown in the third figure). When a certain strip of continuous total reflection light hits the diffusing strip' The strip light is scattered into a plurality of scattered rays toward a plurality of angles. When the incident angles are smaller than the total reflection critical angle, part of the light is emitted from the light exit surface 13 through the light guide body 10. (as in the fourth figure), and the incident angle of the scattered light is still greater than the total The light of the critical angle then 'continues to reflect until the diffusing strip 12 is fired, and the scattering process is repeated. The light source_generating device 30' emits light from the light emitting surface 13 of the light guiding body 1 as shown in the fourth figure. In addition, since the scattered light hits the light exit surface 13 of the circular arc, the light exit surface 13 refracts the scattered light and condenses and illuminates the light exit surface 13 of the light guide body 10 (as shown in FIG. 5), and becomes directional and evenly distributed. Referring to the sixth and sixth B, the figure shows a first application example of the embodiment of the creation of the soul. The light source generating device 30, for example, as a liquid crystal display (not shown) The backlight source is provided with a plurality of light source generating devices 3, and is provided as a direct type backlight module (as shown in FIG. 6A), and light guides 10 of different diameters are used according to different 2' optical requirements, and appropriately Setting the distance between the light source generating devices 30 and the plurality of strip light sources into a large surface light source, the uniform light distribution as shown in FIG. BB can be obtained, and sufficient and uniform directional light is provided as Backlight source, so = can be omitted An optical film (not shown) such as a film or a film, thereby improving the manufacturing process of the liquid crystal display and reducing the manufacturing cost. Further, according to the liquid crystal panel of a small size, the light guide body of the matching length can be selected, because The flux loss is low, and the longer light guide body 1〇 can also obtain a uniform distribution of green light 13 M350730 source, making this creation more suitable for large sizes.

The carriage is oriented toward the grating 121 (as shown in Figure 7 (as shown in Figure 7B), the vehicle is shown in Figure 7A) or sagittal The width and spacing of the facet grating 122 to the optical thumb 121 or the sagittal sliced light peach 122 can control the polarization characteristics of the scattered light sound rays to effectively increase the efficiency of light entering the liquid crystal panel. Referring to Figures 8A and 8B, the figure is a second application example of the first embodiment of the creation. In the prior art, the edge-lit backlight module may have a cold cathode fluorescent tube as a lateral light source or a plurality of light-emitting diodes as a lateral light source, however, whether it is a cold cathode fluorescent tube Or the lateral light source of the plurality of light-emitting bodies "because the light emitted by the light source does not have directivity", the light guide plate must adopt a wedge-shaped light guide plate, and the shape-changing light guide plate is difficult to manufacture. The light source generating device 30 of the present invention can also be applied to the side light-emitting backlight module 'where the light source generating device 30 is disposed on the light guide plate 40 of the one-side optical backlight module', and the line light source generating device 3 is emitted. The light has a directionality, so that the light guide plate 40 can be made into a square plate body for the general optical acryl. The high directional light emitted by the light exit surface 13 of the light guide body 10 enters the light guide plate 40 more efficiently. It will replace the known cold cathode fluorescent tube or the lateral light source of multiple light emitting diodes. Embodiment 2 Referring to the ninth diagram, the light source generating device 3 of the present embodiment is not attached to the reverse film M M 730 film η, and the other light source 20 is disposed at the reflecting surface (10) to increase the brightness of the light. Embodiment 3 Referring to the tenth and tenth drawings, the light source generating device 3 of the embodiment can change the width or position of the diffusing strip 12 according to different optical requirements, and the range of the light emitting light and its directivity are also According to the optical requirement, the illuminating strip d is added as shown in the figure, and the two light-emitting bodies iq are provided with two strips 12 corresponding to the normal line, and the two diffusing strips 12 are opposite to each other. Light body H) The internal reflection of the total reflection, respectively, to the two diffuse shots and scattering, because the relationship between the relative angles of the diffusing strips 12 is staggered, and through the light-emitting surface 13 will scatter the light together = the line will be staggered out of the light will Collecting each other, this will improve the Hui 9 light' (see Figure 10B), and its directional light output increases the liquid crystal display uniformity ratio, which is suitable for large-size liquid crystal displays. Embodiment 4 of the black and white operation Referring to the tenth-figure, as shown in the light source generation diagram of the present embodiment, the scattering strip 12 can be applied as a regular rule of discontinuity or ^0, such as 'night crystal display', which is continuous in line with light, so It can also control the range of light output, which can save light energy when not seen, and simplify the design of the light-shielding mechanism.
