Description of the Invention: «Technical Field of the Invention The present invention relates to a line or surface light-emitting module, and more particularly to a light-emitting diode lamp. [Prior Art] The application of light-emitting diodes in various fields of illumination has flourished in recent years, but the light emitted by the LED modules is, after all, an array point source, in many applications requiring uniform light sources. The application of diode illuminators has not yet reached the demand in this field. Therefore, designers of light-emitting diode illuminators have been constantly betting on improving uniform light source performance. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a light-emitting diode device that emits light uniformly. According to the above object of the present invention, a light-emitting diode lamp is disclosed, which comprises a light guide member, a light reflecting member and at least one light-emitting diode module. The light emitting diode module emits light to the light guide. The reflector is continuously and closely connected to the light guide member, wherein the joint surface of the light guide member and the reflector member is a light reflection surface formed by a plastic injection process. It can be seen from the above that the light-emitting diode lamp of the present invention can uniformly emit light of the light-emitting diode from the light guide member, so that the light-emitting diode lamp can be widely used in various fields to replace the traditional firefly. Applications for light tubes and optical components such as linear and surface types. [Embodiment] 201027001. In the above description, the invention provides a light-emitting diode illuminator with uniform illumination, and the details of the illuminating diode illuminator will be described below by way of embodiments. Referring to Figure 1, there is shown a light emitting diode lamp in accordance with the present invention. The light-emitting diode lamp 100 is mainly composed of a long light guide member 1〇2 and a reflector 104, and other elements are disposed at both ends and side surfaces. The light-transmitting member 102 and the light-reflecting member 104 are joined by a plastic injection method, that is, the light-guiding member and the light-reflecting member are immersed in or in a different color, or are solidified and formed into a continuous densely connected manner, so that the light guiding member is continuously connected. The joint faces φ 103, 105, and 106 between the 1〇2 and the reflectors 1〇4 (see FIGS. 1〇, u, and 12) have no other adhesive, so that the joint faces 103 form a reflective surface having a good reflectance. The light guiding member 1〇2 and the reflecting member 104 may be thermoplastic or thermosetting plastic. The light guide member 1〇2 needs to be a material having good light transmittance. The reflector 1〇4 needs to be a plastic material with a high reflectivity, such as white or other plastic or chemical material that reflects good color. As shown in the first, '11, and 12th drawings, the cross section of the joint surface may be straight (see Fig. 10), arc or semicircle (see Fig. 11), and tapered (see Fig. 12). Fig. 12 depicts a light guide member 1〇2 of a cross-sectional shape. When the joint surface 103 is a straight line, the light of the lamp 1 φ φ is directed in a single direction. When the joint faces 105, 106 are curved, semi-circular or tapered, the light of the luminaire 100 can be directed over a greater range of angles. In addition, there are gaps on both sides of the joint surface, for example, there are gaps on both sides of the joint surface 1〇3 (1〇3b), and there are gaps (105a, 105b) on both sides of the joint surface 105, and the joint surface 1〇6 There are gaps on both sides (l〇6a, 106b). The gap contains air so that the interface between the light guide 102 and the gap is the interface between the light guide 1 2 and the air, not a reflective surface. The above design helps to control the uniformity of the luminaire's illumination and enhance the brightness. In the embodiment of Fig. 1, the side ends of the light guiding member 102 and the reflecting member 104 are provided with a reflector 112 and an LED module 114. The reflector 112 is disposed in the assembly hole of the light guide member 〇2 and the reflector 104 at the end of the assembly, and the inner surface thereof is a high reflectance 4 201027001 reflective surface for introducing light into the light guide 102. The reflector 112 has an interface (toward one side of the LED module 114) for the LED module to be adhered and fixed. The other end of the reflector J 〇 4 also has a reflective section l 〇 4b to reflect light back into the light guide 1 〇 2 . The reflective section 104b is a reflective section of a good chemical material. Please refer to FIG. 2, which illustrates a light-emitting diode lamp according to another preferred embodiment of the present invention. This illuminating one-pole luminaire 200 is used to replace the design of the fluorescent tube. In the light-emitting diode lamp 200, the strip-shaped light guide 202 and the reflector 2〇4 are the main ships, and other components are disposed at both ends and the side surfaces. The light guide 202 and the reflector φ 204 are joined in such a manner that they are closely connected when they are buried or two-color or forcibly formed. The design of the close contact surface of the light guide 202 and the reflector 204 is substantially the same as that of the embodiment of Fig. 1. In the embodiment of Fig. 2, at both ends of the light guide 202 and the reflector 2〇4, a heat sink block 210, an LED module 212, a reflector 214' drive circuit 216, a general body 218, and a pin 220 are disposed. The reflector 214 is attached to the reflective surface of the light guide 202 having a high reflectance. The reflector 214 has a plurality of through holes 214a for allowing light energy emitted by the plurality of LED point sources 212a of the LED module 212 to pass through and reflect. The heat dissipation block 210 is attached to the LED module 212, and has a connection hole 210a for the insertion and engagement of the heat transfer tube 208. The driving circuit 216 is configured to convert a general alternating current type into a direct current to drive the point source 212a of the LED module 212 to emit light. The hollow housing 218 encloses the heat dissipating block 210, the LED module 212, the reflector 214, the driving circuit 216 and the like, and is sleeved at both ends of the light guiding member 2〇2 and the reflecting member 204. The pin 220 passes through the through hole 218a of the body 218 and is connected to the driving circuit 216. The pin 220 has the same pin size as the conventional xenon lamp. In order to make the heat dissipation efficiency better, the heat sinks (206a, 206b) and the heat pipe 208 are disposed on the side of the reflector 204 to further improve the heat dissipation efficiency. One end of the heat pipe 2〇8 is connected to the connection hole 210a of the heat dissipation block 210, and The other parts are sandwiched between two scattered 5 201027001 hot films (206a, 206b). The heat generated by the LED module 212 can be dissipated by the heat dissipation block 210, or can be conducted by the heat pipe 208 to the two heat sinks (2〇6a, 2〇6b) for heat dissipation. The state after the combination of the above elements is as shown in Fig. 2B. Referring to Figure 3, a reflector is illustrated in accordance with a preferred embodiment of the present invention. Fig. 4 is a top view showing the light guide of Fig. 3. In order to allow the lamp 1 能够 to emit light uniformly, in the reflector 3 〇 2 of the rectangular cross section of the embodiment, the cross section of the reflector is gradually increased from the both ends 302a toward the center 3 〇 2b. In other words, the width D2 of the intermediate portion 302b of the reflector is greater than the width 〇1 of the both ends 302a. As for the angle a] φ, it can be adjusted according to the needs. The above design helps to uniformly reflect the light of the entire reflecting member 302 (the reflecting member 3〇2 when the LED module is disposed at both ends of the light guiding members 100 and 2). In addition, when the LED module is only disposed at one end of the light guiding member (the LED module is not provided at the other end of the light guiding member), the design of the fifth embodiment can be adopted, and the cross section of the reflecting member is gradually increased from one end to the other end. That is, the width 〇4 of one end of the reflector is larger than the width 〇3 of the other end. As for the size of the angle A2, it can be adjusted according to the needs. The light guide member is provided with a light emitting diode module at one end of the reflector having a smaller cross section, and no light emitting diode module is disposed at a larger end of the light reflecting member. Referring to Figure 6, there is shown a light reflecting member in accordance with another preferred embodiment of the present invention. Figure 7 is a top view of the reflector of Figure 6. In order to allow the luminaire 100 to emit light uniformly, in the reflector 4 〇 2 of the approximately semicircular cross section of the present embodiment, the cross section of the reflector is gradually increased from the both ends 402a toward the middle 402b. In other words, the width % of the middle portion 402b of the reflector is greater than the width D5 of the both ends 402a. As for the size of the angle 8.3, it can be adjusted according to the needs. The above design helps to uniformly reflect the light of the entire reflector 402 (the reflector 402 when the LED module is disposed at both ends of the light guides 1 and 2). Please refer to FIG. 8 , which illustrates a 201027001 reflector in accordance with another embodiment of the present invention. Figure 9 is a top view of the reflector of Figure 8. In order to allow the luminaire 100 to emit light uniformly, in the reflector 5 〇 2 of the present embodiment, the cross section of the reflector is gradually increased from one end 502a to the other end 50215. In other words, the width Ds of one end 5〇2b of the reflector is larger than the width ο of the other end 502a. As for the size of the angle ^, it can be adjusted according to the needs. The above design helps to uniformly reflect the light of the entire reflecting member 5〇2 (the reflecting member 5〇2 when the LED module is disposed at both ends of the light guiding members 1〇〇 and 2〇〇). According to the preferred embodiment of the present invention, the light-emitting diode 0 lamp of the present invention can uniformly emit light of the light-emitting diode from the light guide member, so that the light-emitting diode lamp can be widely applied to various fields. In order to replace the traditional fluorescent tube and linear 'face type optical components. Although the present invention has been described above in terms of a preferred embodiment, it is not intended to limit the invention, and it is obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims. φ [Circular Description] The above and other objects, features, advantages and embodiments of the present invention will become more apparent and understood.
