specific Embodiment approach 1
[0038] Embodiment 1. A device for generating a rectangular line spot in this embodiment includes a light source 1, a convex lens 2, a conical reflector 3, a mounting frame 4 and a reflector 5;
[0039] The light source 1, the convex lens 2 and the conical reflector 3 are all fixed on the mounting frame 4;
[0040] The reflector 5 includes four reflectors, the four reflectors are all fixed on the outer wall of the mounting frame 4, and the four reflectors and the optical axis of the convex lens 2 have an included angle between 0° and 90°; A cover body is formed by splicing the reflecting mirrors; the conical reflector 3 is located in the cover body;
[0041] After being refracted by the convex lens 2, the light emitted by the light source 1 is reflected by the reflective surface of the conical reflector 3 and the reflective surfaces of the four reflective mirrors in turn, and finally exits from the opening of the cover.
[0042] Such as figure 1 As shown, the device for produ...
specific Embodiment approach 2
[0045] Embodiment 2. Compared with Embodiment 1, the four reflective lenses in this embodiment include two identical isosceles triangular lenses and two identical isosceles trapezoidal lenses;
[0046] The waist length of the isosceles triangle lens is equal to the waist length of the isosceles trapezoid lens;
[0047] And the two waists of one piece of isosceles triangular lens are respectively connected with one waist of two isosceles trapezoidal lenses, and the two waists of another piece of isosceles triangular lens are respectively connected with the other waist of two isosceles trapezoidal lenses. The upper bottom of the waist trapezoidal lens is connected to form a cover body;
[0048] The optical axis of the convex lens 2 passes through the midpoint of the upper bottom of the isosceles trapezoidal lens.
[0049] Such as figure 2 As shown, in this embodiment, two identical isosceles triangular lenses and two identical isosceles trapezoidal lenses are combined to form...
specific Embodiment approach 3
[0050] Embodiment 3. Compared with Embodiment 1, the four reflective lenses in this embodiment include four identical isosceles triangle lenses;
[0051] The vertices of the four isosceles triangular lenses gather at one point, and the waists of the adjacent two isosceles triangle lenses are connected to form a cover body;
[0052] The optical axis of the convex lens 2 passes through the apex of the isosceles triangular lens.
[0053] In this embodiment, four identical isosceles triangular lenses are used, that is, the two isosceles trapezoids in Embodiment 2 are transformed into the same isosceles triangular lenses as the other two isosceles triangle lenses, so that the four identical isosceles triangle lenses The triangles can be combined to form a cover body that is closed at the waist and has a closed square opening. All four lenses can reflect the light reflected from the conical reflector 3 and shoot out from the closed square opening, thereby forming a square on the pro...
