The through holes 13 are pierced, and the positioning holes 14 are disposed at intervals along the long direction X. The through holes 13 are interposed between the positioning holes 14. In the present embodiment, the material of the material plating layer 12 of the wall body u is metal. The side walls 2G of the μ mirror extend obliquely upward and outward from opposite sides of the bottom wall 1 in the long direction, and an angle Θ is defined between the side walls 2 (see FIG. 2). In the embodiment, the angle 0 is between 8 〇. To 12 baht. Between. The sidewalls 20 respectively have a wall 21 connected to the wall u, a mirror plating layer 22 fixed to the inside of the wall 21 and connected to the mirror plating layer 12, and a mirror plating layer 22 formed on the mirror layer 22 Inner side 23 of the body. The inner side faces 23 of the side walls 20 respectively have a plurality of reflecting arcuate regions 231 which are spaced apart in the longitudinal direction and which are inclined outwardly and upwardly. The reflecting arcuate regions 231 of the inner side faces 23 correspond to each other. The perforations 13 of the bottom wall 1 are respectively between the corresponding reflective arcuate regions 231. In the present embodiment, the material of the wall 21 is plastic, and the material of the mirror plating layer 22 is metal. The horizontal retaining walls 30 project outwardly from the top edge of the wall 21 of the side walls 2 〇 201028615 along the longitudinal direction. In this embodiment, the horizontal wall 30 is made of plastic. * Soil: The end walls 40 are respectively disposed on the opposite ends of the bottom wall 1 and the side walls along the longitudinal direction X, and the bottom wall 1G and the side walls 2 are closed at both ends. The end walls 40 respectively have a wall body 41 connected to the wall body u and the wall bodies 21, and are fixed to the inside of the (four) body 41 and electrically connected to the mirror surface. (4). The mirror plating layer 22 A mirrored plating layer 42 is attached. In this embodiment, the material of the wall 41 is plastic, and the material of the mirror electrode layer 42 is metal. In this embodiment, the wall body u of the bottom wall 10, the wall body 21 of the side wall 2, the horizontal blocking wall 3〇 and the wall 41 of the end wall 4〇 are formed by plastic body injection molding.

As shown in FIG. 1, 4, and 5, when the reflective element 1 is mounted on the socket 61 of the waterproof lamp 200, the two holes 9 are respectively passed through the positioning holes 14' of the bottom wall 10. The lamp holder 61 is locked to position the reflective element 100 above the circuit substrate 62, and the LED lamps 63 are respectively protruded upward from the through hole 13 of the bottom wall 10, because the side walls are The reflective surface area 23 can respectively reflect the images of the LED lamps 63. Therefore, as seen from FIG. 4, in addition to the original six LED lamps 63, the left and right sides of the six LED lamps 63 are additionally generated. There are twelve reflection images 63 两 in two rows. Thus, when the power is turned on, the projection light 631 of the LED lamps 63 is reflected by the reflective arc surface 23 of the side walls 20 of 6 201028615, and a large range can be generated. The projected area is 300' for large-area projection lighting applications. Through the above description, the advantages of the present invention can be further summarized as follows: Since the reflective curved surface region 23 of the side wall 20 of the present invention can respectively reflect the images of the LED lamps 63, and the reflective curved surface regions 23 extend the long direction The X spacing is set so that when the projected light 63 1 of the LED lamps 63 is reflected by the reflective arcuate regions 23 of the side walls 20, the mutually reflecting reflective arcuate regions 23 can project the LED lamps 63. The light 631 reflects and forms six umbrella-shaped beams, and the six umbrella beams collide with each other, so that a large-area projection area extending along the long direction X can be generated, which is suitable for large-area projection illumination, and The reflective arcuate regions 23 can cause the light emitted by the LED lamps 63 to have a condensing effect, and a uniform illuminance is formed on the projection area 300, so that the projected ray on the projection area can be made 3 It is evenly distributed without generating spots. Referring to Figures 6 and 7, a second preferred embodiment of the present invention is similar to the first preferred embodiment in that the inner side 23 of the side walls 2G is different. The reflective arcuate regions 231 each have a plurality of bump portions 232 that are spaced apart and project inwardly. Thus, the second preferred embodiment can achieve the same purpose and effect as the first preferred embodiment described above, and soften the projected light. > Figures 8 and 9 are a third preferred embodiment of the present invention. The third preferred embodiment is similar to the first preferred embodiment, and the differences are as follows: 201028615 The reflective arcuate regions 231 of the inner side surface 23 have a plurality of lattice-shaped surface portions 233 arranged in an array. Thus, the third preferred embodiment can achieve the same objects and effects as the first preferred embodiment described above. Referring to FIG. 10, a fourth preferred embodiment of the present invention is similar to the third preferred embodiment, and the difference is that: the reflection of the inner side surface 23 of the side walls 20 The arcuate regions 231 each have a hexagonal face 234 that is adjacent to each other. Thus, the fourth preferred embodiment can achieve the same objects and effects as the third preferred embodiment described above. In summary, the light source reflecting element of the LED lamp of the present invention can not only achieve a wide range of projection area of the LED lamp, but also form a uniform illuminance, so that the object of the present invention can be achieved. However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention, All are still within the scope of the patent of the present invention. ❹· 8 201028615 [Simplified illustration of the drawing] Fig. 1 is an exploded perspective view of the light source reflecting element of the LED lamp of the present invention, a comparative example and a waterproof lamp; FIG. 2 is a n _ π cutting line in FIG.
