The head end 11 is radially provided with a group of façades, and a plurality of light-emitting diodes (not shown) are disposed on the group surface, and the light generated by the light-emitting diodes is substantially along the axial direction of the body 10 The object is directed away from the body 10.

The reflector 100 includes a connecting portion and a light reflecting portion. The connecting portion is substantially a plate body 110, and the reflecting portion is substantially a cover body 120. One side of the cover 120 is connected to one side of the plate body 110, the cover 120 and the plate body 110 together form a reflective space 101, and the reflective space 101 has an open surface 102. The plate body 110 corresponds to the neck portion 21. The plate body 110 has an outer edge 111, a front edge 112, an inner edge 113 and a flat surface 114. One end of the front edge 112 is connected to the outer edge 111 and the other end is connected to the inner edge 113. The front edge 112 is adjacent to the opening. The face 102 has an outer edge 111 connected to the cover 120 and a flat surface 114 located in the reflective space 101. The cover 120 corresponds to the light-emitting portion 20, and the cover 120 has a curved surface 121 and an edge 122. The curved surface 121 is located in the reflective space 101, and the flat surface 114 abuts the curved surface 121 of the cover 120, and the edge 122 is adjacent to the open surface 102.

The plate body 110 is rotatably and detachably connected to the neck portion 21, and the cover body 120 is correspondingly disposed around the light emitting portion 20. In this embodiment, the leading edge 112 is coplanar with the edge 122, in other words, the opening surface 102 is a plane that is flat without bending, and the leading edge 112 and the edge 122 are co-located on the periphery of the opening surface 102; further, the opening surface 102 and the light emitting portion The 20 overlaps, that is, a portion of the light-emitting portion 20 is located in the reflective space 101 and the other portion is located outside the reflective space 101. In other embodiments, the leading edge and the edge may not be coplanar, that is, the opening surface is not planar; in addition, the light emitting portion may also be designed to be completely located in the reflective space, that is, the light emitting portion does not overlap the opening surface.

The neck portion 21 is substantially circular in configuration, the inner edge 113 of the plate body 110 forms a circumferential length greater than 1/2, and the circular opening greater than 1/2 enclosed by the inner edge 113 is complementary to the neck portion 21. The two ends of the inner edge 113 are adjacent to the opening surface 102 and a first notch 115 is formed between the two ends thereof. The first notch 115 is disposed corresponding to the width of the neck 21 . Specifically, the width of the first notch 115 is smaller than that of the neck 21 . Maximum width (or diameter). Therefore, the inner edge 113 is detachably engaged with the neck 21 and is rotatable relative to the neck 21, and the associated cover 120 is rotatable about the light-emitting portion 20 to adjust the relative positions of the two. The curved surface 121 of the cover 120 corresponds to the light-emitting portion 20, and the curvature distribution and geometric structure of the curved surface 121 affect the light pattern of the light-emitting portion 20, that is, the angle of illumination and the degree of concentration or diffusion.

In the present embodiment, the plate body 110 also has a groove 116, the groove 116 is adjacent to the inner edge 113, and the groove 116 is disposed corresponding to the inner edge 113. The grooves 116 are two and disposed opposite to each other, and the ends of the two grooves 116 respectively penetrate the front edge 112 to form two second notches 117. When the reflector 100 is to be engaged with the body 10 and the light-emitting portion 20, the neck 21 is aligned and passed through the first notch 115. Because of the relationship between the groove 116 and the second notch 117, the first notch 115 can be necked. 21 is slightly extended, at the same time the second notch 117 and the groove 116 are slightly squeezed to allow the neck 21 to pass, after the neck 21 is completely engaged with the inner edge 113, the second notch 117, the groove 116 and The first notch 115 is restored to its original width because of its elasticity, and the reflector 100 is engaged with the body 10 and the light-emitting portion 20 at this time. When the reflector 100 is to be detached from the main body 10 and the light-emitting portion 20, the reverse operation may be performed as described above.

In summary, the present invention provides a reflector and an illumination device using the same, which can reflect the light generated by the illumination portion of the illumination device to a desired position by using a reflector, and further diffuse the illumination range and the illumination angle. In this way, it is possible to avoid insufficient illumination in the place where illumination is required, which not only improves the light utilization rate, but also reduces energy waste.
