[0036] See also Figures 1 to 4In one embodiment of the present application, a reflector 100 is provided, which can be used in conjunction with a light source 200 to perform mixed light reflection processing on the light emitted by the light source 200, so that the projected light is uniform, which can not only reduce the messy light spots, but also make the light more integrated and obtain a better lighting effect. The reflector 100 includes a cover body 10 and a mixed light lens 20.

[0037] Specifically, the cover body 10 has openings at both ends and is hollow inside, and the openings at both ends of the cover body 10 are respectively a light inlet 101 and a light outlet 102. The end of the cover body 10 provided with the light inlet 101 is used to connect the light source 200, and the inner wall of the cover body 10 is a reflective surface; in the direction from the light inlet 101 of the cover body 10 to the light outlet 102, the extension trend of the reflective surface is a gradually expanding parabola, and the light emitted by the light source 200 is reflected by the reflective surface to form parallel light perpendicular to the plane where the light outlet 102 is located.

[0038] The light mixing lens 20 is disposed at the light inlet 101 of the cover body 10 . The light emitted by the light source 200 can first be mixed by the light mixing lens 20 and then enter the interior of the cover body 10 , and then be reflected by the reflection surface to form parallel light and be emitted from the light outlet 102 .

[0039] In some embodiments of the present application, the cover body 10 includes a main body 11 and an inlet end face portion 12 and an outlet end face portion 13 connected to both ends of the main body 11. The main body 11 is open at both ends and is hollow inside. A light inlet 101 is provided on the inlet end face portion 12, and a light outlet 102 is provided on the outlet end face portion 13. Both the light inlet 101 and the light outlet 102 are circular, and the diameter of the light inlet 101 is smaller than the diameter of the light outlet 102.

[0040] In some examples, the cross section of the main body 11 is circular in the axial direction of the cover body 10. The area of ​​the cross section of the main body 11 gradually increases in the direction from the light inlet 101 to the light outlet 102. That is, in the cover body 10 of this example, the opening of the main body 11 used to connect the inlet end face 12 is a small opening, and the opening of the main body 11 used to connect the outlet end face 13 is a large opening. In the direction from the light inlet 101 to the light outlet 102, the main body 11 gradually expands.

[0041] The inner wall of the main body 11 is a reflective surface. In the direction from the light inlet 101 of the cover body 10 to the light outlet 102, the extension trend of the reflective surface is a gradually expanding parabola, and the light emitted by the light source 200 is reflected by the reflective surface to form parallel light perpendicular to the plane where the light outlet 102 is located.

[0042] In other embodiments of the present application, the light inlet 101 and the light outlet 102 of the cover body 10 may also be other shapes, such as regular shapes such as a quadrilateral, a triangle, an ellipse, or other irregular shapes, which are not specifically limited here.

[0043] In some examples, the housing body 10 may further include a shell 14, which is disposed on the outer periphery of the main body 11, and the two ends of the shell 14 are respectively connected to the outer periphery of the inlet end surface 12 and the outer periphery of the outlet end surface 13. There is a gap between the shell 14 and the main body 11, and the gap can form a heat-insulating space.

[0044] The housing 14 is disposed outside the main body 11 , which can avoid direct contact between the user and the main body 11 , prevent the high temperature and heat accumulated on the main body 11 from scalding the user, and ensure the safety of the user.

[0045] In some examples, a hollow portion may be provided on the housing 14. The hollow portion can connect the heat-insulating space with the external environment, so that the high temperature and heat accumulated on the main body 11 can be quickly dissipated through the hollow portion, thereby preventing the high temperature and heat from accumulating on the main body 11 for a long time, ensuring the normal and effective use of the reflector 100 and ensuring its long service life.

[0046] In some embodiments of the present application, the mixing lens 20 is arranged at the light inlet 101 of the cover body 10, and the light emitted by the light source 200 can first pass through the mixing processing of the mixing lens 20 and enter the interior of the cover body 10, and then be reflected by the reflecting surface to form parallel light and be emitted from the light outlet 102.

[0047] The mixing lens 20 is directly arranged corresponding to the light inlet 101 of the cover body 10, so that the light emitted by the light source 200 installed at the end of the cover body 10 with the light inlet 101 can be directly mixed through the mixing lens 20 without the need for a mixing path. The mixing efficiency is higher, and the light integrity is better. In addition, it is also conducive to realizing the overall miniaturization and lightweight design of the reflector 100.

[0048] In some examples, the surface of the light-mixing lens 20 may be frosted. The light-mixing lens 20 with a frosted surface can better mix and diverge the light, improve the uniformity of the light, thereby reducing messy light spots and improving the light effect.
