[0081] Example 2

[0082] This embodiment provides a lens and reflective cup assembly structure. Based on the embodiment 1, the lens is made of a brittle material with a light transmittance greater than or equal to 91%.

[0083] The brittle material for making the lens may be PMMA (polymethyl methacrylate) material, high light transmittance PC (polycarbonate) material or PET (polyethylene terephthalate) material, etc.

[0084] A lens made of a material with a transmittance greater than or equal to 91% has excellent optical properties and can meet the increasingly high requirements for the optical performance of lenses in the market.

[0087] It should be noted that the assembly structure provided in the present application has strong versatility and can also be used for lenses made of materials with a light transmittance of no more than 91%.

[0088] The lens and reflector assembly structure described in this embodiment is shown in FIG. Figure 3-8 The extending portion is a fastening member 5 with a side protrusion 6 at the end, and the accommodating portion is a fastening groove 7.

[0103] Example 3

[0104] This embodiment provides a lens and reflector cup assembly structure, see Figure 9-12 Based on Example 1, the difference from Example 2 is that, in this embodiment, the protruding portion is an assembly part 9, the accommodating portion is an assembly groove 10, and the assembly part 9 can extend into the assembly groove 10 and have an interference fit with the assembly groove 10.

[0105] The fitting 9 protrudes toward the light incident side of the lens optics 3 .

[0106] The assembly part 9 can be a column, a block, a plate, etc. In order to save space, the present embodiment preferably uses a flat plate, and the thickness direction of the plate is perpendicular to the side of the lens mounting edge 1 at the mounting position.

[0107] The assembly groove 10 may be a slot or a hole. To facilitate installation and save space, the assembly groove 10 is a slot arranged on the side of the lens mounting edge 1 .

[0108] The size of the assembly groove 10 is slightly smaller than the assembly part 9, so that the assembly groove 10 and the assembly part 9 can be interference fit; the width of the assembly part 9 can be gradually reduced in the direction away from the lens mounting edge 1 to facilitate insertion into the assembly groove 10.

[0109] The lens and reflector combined assembly structure provided in this embodiment can minimize the movable gap between the lens and the reflector through the interference fit between the assembly part 9 and the assembly groove 10, improve the tightness of the connection between the two, make the assembly structure more stable, and reduce the deviation of the lens and the reflector caused by shaking.

[0110] Preferably, an auxiliary groove 11 is disposed adjacent to the side of the assembly groove 10 .

[0111] The auxiliary groove 11 may be a slot or a hole. In this embodiment, it is preferably a slot similar to the assembly groove 10 . The auxiliary groove 11 and the assembly groove 10 are arranged in parallel, and the sides of the two are adjacent.

[0112] When the assembly part 9 is interference fit with the assembly groove 10, the reflective cup mounting edge 2 will be squeezed to cause deformation. The auxiliary groove 11 is arranged on the side of the assembly groove 10 to balance the structural deformation of the assembly groove 10 and release the stress on the reflective cup mounting edge 2 during interference fit, which is beneficial to structural stability and safety.

[0113] Further preferably, a positioning piece 12 is provided on the reflective cup, and the positioning piece 12 is used for positioning when connecting the light source bracket / lamp; a crimping piece 15 is provided on the lens mounting edge 1, and the crimping piece 15 is used for pressing and fixing the light source bracket / lamp.
