New Description: [New Technology Field] This creation is about a light-conducting structure, especially a light-conducting structure that can be used in lED lamps to produce multiple light-emitting surfaces. [Prior Art] The LED lamp of the prior art has a light-emitting mode in which the phosphor powder is excited by the light-emitting diode into white light, and then a light-transmitting outer cover is added to the existing LED lamp, but the light-emitting diode is used. The small volume of the module is concentrated around the module, and the outer cover is flat design. Only the function of transmitting light can make the LED lamp have less variability, and the light source is concentrated on the LED chip. Around the group, if there are more space restrictions on the lamps or ornaments of special shapes, the light source generated by the LED lamps cannot be effectively shot, that is, useless. In the existing LED luminaires, as described above, the variability of the light source is small and the light source is concentrated and directly imposed on the periphery of the illuminating diode module, which is necessary for further improvement. [New content] The creator has a fascination in the existing LED lamps with less variability in the light source and ▲ the light source has more restrictions on the emission point, and is redesigned. #由本的光光的光光结构, The technical hand a used for the purpose of innovating the above-mentioned problems is to provide a light guiding structure of a _/, a plurality of light-emitting surfaces, which is a light guiding column, and the It light guiding column is a transparent column. The portion is a light guiding rod with a light guiding function; the light guiding column 3 _ is disposed on the outer wall surface of the V-shaped concave surface structure, and is provided with a ring-shaped convex lens, and is surface-treated on the surface to form a plurality of light-emitting surfaces, thereby enhancing the light source of the σ LED lamp Change and enhance its glare effect. 2. Set a ring with a reflective surface outside the bottom end of the light guiding structure to concentrate the four scattered light sources upward into the light guiding rod, and the light source concentrates better. - 3. With this light guiding structure, the light source and the light exiting point can be separated to match the case of the special & type of luminaire or display space. * [Embodiment] As shown in Fig. 1 and Fig. 2, the light guiding structure with a plurality of light-emitting surfaces designed by the present invention is a light guiding column 20, and the light guiding column 20 is a long cylinder, and the material is Transparent plastic or made of flexible fiber material. The light guiding rod 20 has a top end and a bottom end, wherein the upper end is provided with an inner concave surface 21 in the shape of -S \/^*1 AA rV^V, and the light guiding column 2G is provided with the concave surface 21 Forming a ring-shaped convex lens 10, the light guide column 20 is under the '23', and the δ is freely disposed. The chamber 3 is a semi-circular concave or curved concave portion. The wall surface of the valley chamber 23 is formed as a light-receiving structure. And at the bottom end thereof, a metal outer ring 24 is provided, which has a reflecting surface 24, and the middle portion of the light guiding column is a light guiding rod 22 having a light guiding function, as shown in FIG. A layer of phosphor powder is applied to the inner wall surface of the valley to 23. When the light guiding structure of the present invention is implemented in a lamp, a light-emitting diode module 41 is disposed on the lamp holder and opposite to the position of 23, which carries the wafer 40, and 5 pieces of 4 turns to emit a light. The angle of illumination emitted by the wafer is
