[0055] For ease of understanding, the specific structures of each component in the present invention will be further described below with reference to the accompanying drawings.
[0056] 1. Reflector
[0057] like Figures 6 to 8 As shown, the reflector includes a reflective cup body 10, the reflective surface 14 of the reflective cup body 10 is in the shape of an ellipsoid, and the reflective surface 14 of the reflective cup body 10 is formed by an elliptical arc around the long axis a of the ellipse where the elliptical arc is located A semi-revolution surface formed by rotating 180°; the ellipse arc is the arc segment enclosed by the long axis a and the short axis b of the ellipse in the same quadrant.
[0058] like Image 6 As shown, the reflective surface 14 of the reflective cup body 10 is also the inner wall surface of the reflective cup body 10 .
[0059] In the reflector of the present invention, the length ratio between the major axis a and the minor axis b of the...
