New description: [New technical field] The present invention relates to a light source device, and more particularly to a light source device having a light guiding column. [Prior Art] A Light Emitting Diode (LED) is a semiconductor element mainly composed of a III-V element compound semiconductor material. Such semiconductor materials have the property of converting electrical energy into light. In detail, when a current is applied to such a semiconductor material, electrons inside the semiconductor material are combined with the holes, and excess energy is released in the form of light to achieve an illuminating effect. Since the illuminating phenomenon of the illuminating one body is not a thermal luminescence or a discharge luminescence, but a cold luminescence, the life of the illuminating diode device can be as long as 100,000 hours or more, and no idling time is required. In addition, the light-emitting diode device has the advantages of fast reaction speed (about 10_9 seconds), small size, low pollution (no mercury), high reliability, and suitable mass production, so its application field is very extensive. 1 is a conventional light source device using a light emitting diode. Referring to FIG. 1 and FIG. 4, the light source device 100 includes a strip substrate 1A and a plurality of light emitting diodes 120, wherein the light emitting diodes 12A are disposed on the strip substrate 11A. Each of the light-emitting diodes 120 is adapted to emit light 122, and these light rays 122 form an elongated pattern of light P. In the prior art, in order to make the light source device 1 〇〇 have a long illumination pattern P, a plurality of light-emitting diodes 12 需 are used, so that the light source device 1 〇〇 3 Ο 6 doc/e has a high production cost. . In addition, since the number of the light emitting diodes 120 is large, the light source device 100 is more energy in operation. Further, the portion of the illumination pattern P located directly above the light-emitting diode 12 is generally bright, resulting in uneven brightness of the illumination pattern p.

Structure. In the creation of this creation - the implementation of the above-mentioned light diffusion _ is a rough seam. In one embodiment of the present invention, the light guide column has a plurality of bends. The light guide column is used to emit light from the light source from the light exit surface of the light guide column to form an elongated illumination pattern. Compared with the conventional technology, a plurality of light sources are required, and the light source device of the present invention can provide a long-length illumination pattern by only one light source, thereby saving production cost. The above and other objects, features and advantages of the present invention will become more apparent from the following description. [Embodiment] FIG. 2 is a schematic view of a light source device according to an embodiment of the present invention, and FIG. 3 is a schematic view of a light guide column of FIG. Referring to FIG. 2 and FIG. 3, the light source device 200 of the embodiment includes a light guide 210, a plurality of reflective layers 220, and a first light source 230. The light guide column 210 has a first side surface 212 9 M3 06644 〇 (^ and a second end surface 214 and a side surface 216 and a plurality of side surfaces 218 connected between the first end surface 212 and the second end surface 214, wherein the side surface 218 216 is a light-emitting surface. At least one of the side surfaces 218 is provided with a plurality of light diffusion patterns 219. The reflective layer 220 is disposed on the side surface 218. The first light source 230 is disposed beside the first end surface 212, and the first light source 230 is The light 232 is incident on the light guide 210 through the first end surface 212 and exits from the side surface 216. In the above light source device 200, the reflective layer 220 can be a reflective coating or a reflective element, such as a mirror. Further, the second end surface 214 A reflective layer 220 can also be disposed on the substrate. In this embodiment, the light guiding column 210 is a quadrangular prism, and the side surface 216 and the side surface 218 are all planar. In addition, the first light source 230 is, for example, a light emitting diode, and the light emitting diode In this embodiment, since the reflective layer 220 is disposed on the second end surface 214 and each of the side surfaces 218, the light 232 is incident on the light guide column 210 from the first end surface 212. Reflection between 220, The light exiting pattern 219 is used to cause the light 232 to diffuse the light 232. The light diffusing pattern 219 may be a groove, a printed dot or a rough structure, wherein the groove is, for example, V-cut. In addition, the side surface 216 is a rectangular plane, and the length and width of the side surface 216 are L1 and L2, respectively, and 1$L1/L2S2000, preferably 5$L1/L2S200. Since the light guide 210 of the present embodiment can emit the light 232 emitted by the first light source 230 from the side surface 216 to form an elongated illumination pattern, the light source device of the present invention is used in comparison with the prior art. 2〇〇 Only one first light source 230 is required to provide a long illumination pattern, so that the production cost can be saved by 10]V13 Ο 6 64^wf.doc/e. Furthermore, since the number of light sources is small, the light source device 200 It is more energy efficient to operate. It is worth mentioning that 'in this creation, the light intensity distribution of the illumination pattern can be adjusted by changing the spacing between adjacent two light diffusion patterns 219. For example, the light beam 232 is incident on the light guide column. After 21〇, the closer to the first end face 2 The stronger the intensity of the light 232 of 12, the weaker the intensity of the light 232 closer to the second end surface 214, which may result in a less uniform brightness of the illumination pattern. Therefore, the present embodiment proposes a light guide column to improve this phenomenon. Referring to FIG. 4, in the embodiment, by adjusting the spacing between the two light diffusion patterns 219 on the same reflecting surface 218, the phenomenon of π degree uncle of the above illumination pattern is improved. In the light guide column 21〇a, the pitch of the first contact surface 212 (ie, closer to the first light source 23〇) is greater than the distance from the first end surface 212 (ie, farther away from the first light source 23〇). That is, the pitch D1 > D2 > D3 > D4 > D5. Since the distance between the adjacent two light diffusion patterns 219 which is farther away from the first end surface 212 is smaller, the light 232 which is farther away from the first end surface=12 is more easily transmitted to the light diffusion pattern 219, and is further diffused by the light diffusion pattern 219. Diffusion and exit from the side 216, which can improve the problem of uneven brightness of the illumination pattern. It should be noted that although the above-mentioned spacing between the adjacent two light diffusion patterns is adjusted to make the light intensity distribution of the illumination pattern relatively uniform, the present invention can also be adjusted by adjusting the spacing between the adjacent two light diffusion patterns 219. The light intensity distribution of the illumination pattern is as desired. ..., FIG. 5 is a schematic view of a light guide column according to still another embodiment of the present invention. Referring to FIG. 5, the light guide column 210b is similar to the light guide column 210.
