The light-transmitting lens holder 12 generally includes a mounting surface 121 adjacent to the light-emitting diode u and defining a mounting groove 120, a light-transmissive surface 122 spaced apart from the front surface of the mounting surface 121, and a surrounding connection A reflecting surface 123 on the periphery of the light transmitting surface 122. The mounting slot 120 is mounted for the light emitting diode u. When the light emitting diode U is mounted on the mounting #12G t, the material light emitted by the light emitting diode is first reflected toward the reflection Φ 123 and then reflected by the reflecting surface 123. When a part of the light is emitted toward the light-transmissive surface 122, it is directly emitted toward the light-transmissive surface 122, and all the light that is emitted forward through the light-transmissive surface 122 can be used for illumination. Referring to FIG. 3 is a schematic diagram of the light intensity distribution of the conventional illumination module, wherein the horizontal axis is the viewing angle seen from the transparent lens holder 12 toward the front, that is, through the central axis of the transparent lens holder 12. The line 13 has an angle with the line of sight 14 on the light transmissive surface 122, and the vertical axis represents the intensity of light. Since the reflective surface 123 of the conventional light-transmitting lens holder 12 is an inclined surface with a fixed slope, when it is used in conjunction with the light-emitting diode U, the light that is reflected by the light-emitting surface 123 and then emitted toward the transparent surface 122 is Most of the boring tools are concentrated in the front position of the center of the light-transmitting lens holder 12, and the light intensity at the periphery of the light-transmitting lens holder 2 is higher than that of the 5 M296480: When the intensity of the light is at most 15 曰 center and the angle of view angle becomes larger toward the outside, the light intensity is rapidly weakened. The above-mentioned light-transmissive mirror base 12 allows the light to be concentrated only in the front part, and the two sides are weak, and this (four), Mingyu is to be returned to the branch or the flashlight, § when the river is coming, The person who feels that the money is too glaring and uncomfortable; while the outside light is too weak, there is a doubt that the brightness is insufficient, that is, the light-transmitting lens holder 12 causes the uneven distribution of the light source and the lack of breadth. [New content] Therefore, the object of the present invention is to provide a lighting module in which the light-transmitting lens holder has different reflecting surfaces and uniform light distribution. Thus, 'the present invention module package: a light-emitting member that generates a light source' and a light-transmitting mirror for mounting the light-emitting member, the light-transmitting lens holder includes a base surface adjacent to the light-emitting member, and a base surface The light-transmissive surface of the partition, the mounting surface of the mounting groove for mounting the light-emitting member is disposed from the base surface to the light-transmitting surface, and a reflecting surface connected between the base surface and the light-transmitting surface. The reflective mask has a first slope region adjacent to the illuminating member and a second slope region between the first slope region of the 5 hai and the light transmissive surface, and the slope is different from the first slope region. By the arrangement of the slope regions of the reflecting surface of the light-transmitting lens holder, the light that is directed toward the light-transmitting surface of the light-emitting member is reflected by a plurality of different angles, and then emitted toward the light-transmitting surface, and the direction in which the light is emitted is It is evenly distributed on the various viewing angles in front of the transparent mirror holder, thereby achieving the advantage of uniform light distribution. [Embodiment] ^ M296480 The description of the novel and other technical contents, features and effects will be clearly shown in the detailed description of a preferred embodiment of the reference drawing. 4, 5, and 6, a preferred embodiment of the novel lighting module can be used as a lighting device such as a car flashlight, including a light-emitting member 3 for generating a light source, and a light-permeable member 3 for mounting the light-emitting member 3 Light mirror holder 2. The illuminating member 3 can be a light-emitting diode, a bulb or other component that can be used as a light source, and the illuminating member 3 of the present embodiment uses a light-emitting diode to provide more power-saving illumination. The light-transmitting lens holder 2 includes an annular base surface 21 adjacent to the light-emitting member 3, a mounting surface 22 recessed from the base surface 21, a light-transmissive surface 23 spaced apart from the base surface 21, and a gradually enlarged The reflecting surface 24 between the base surface 21 and the light transmitting surface 23 is connected to the ground. The mounting surface 22 of the present embodiment protrudes from the base surface 21 about a central axis 25 and defines a mounting slot 221 with an opening facing rearward for mounting the illuminating member 3. The light transmitting surface 23 is located in the light emitting direction of the light emitting member 3, has a circular outer ring side 231, and is curved radially inward from the outer ring side 231 and protrudes forward and curved. The reflecting surface 24 of the embodiment is also disposed around the central axis 25, and includes a first slope region 241, a second slope region 242, a third slope region 243, and a slope from the adjacent to the retreating base surface 21. The expansion zone 244, and a flat winding zone 245, wherein the slope zones 241, 242, 243 are all inclined, viewed from a side cross-sectional view, the slope of the first slope zone 241 is the largest, the 7th M296480 slope The slope of the region 243 is the smallest, and the oblique region 244 is connected steeply between the third slope region 243 and the flat region 245. When the illuminating member 3 is installed corresponding to the transparent lens holder 2, a part of the light emitted by the illuminating member 3 is incident on the reflecting surface 24, reflected by the reflecting surface 24, and then emitted toward the transparent surface 23, Part of the light is directed directly toward the light-transmissive surface 23. When the light is incident on the reflecting surface 24, since the slopes of the slopes 24, 242, and 243 are different, the light can be reflected by the reflecting surface 24 at a plurality of different reflecting angles, and then emitted toward the light transmitting surface u. . By changing the slope of the slope regions 241, 242, and 243, the angle of reflection of the light can be changed, that is, the angle at which the light is emitted from the light transmitting surface 23 is changed, so that the direction in which the light is emitted from the light transmitting surface 23 is dispersed and uniform. It will not focus on only one direction. In addition, the arcuate arrangement of the light transmissive surface 23 has the advantage of increasing the angle at which light is emitted and enlarging the shape of the light, thereby increasing the breadth of the light distribution. Therefore, in the distribution diagram of the corresponding angle of view of the light intensity of FIG. 6, the angle of view is the central axis 25, and the angle between the light-transmitting surface 23 and the direction of a line of sight (as shown in FIG. 5) can observe the light of the present invention. The distribution of intensity as a function of the curve 27 of the viewing angle is moderated over the conventional curve 4. When the viewing angle is zero, the light intensity is strongest and forms a central peak 271. As the viewing angle increases to the outside, the intensity of the light slowly decreases but remains above a certain intensity, improving the light of the Baizhi lighting module outside the transparent mirror mount. The lack of deficiency, so the use of this new type can indeed evenly distribute the light. In summary, the present invention is to provide a reflecting surface with different slopes.
