Detailed ways

As shown in FIG. 1 , a hemispherical reflecting high beam of an automobile according to the present invention includes a lamp holder 1, a positioning groove 14 is machined at the bottom of the inner cavity 11 of the lamp holder 1, and a light source assembly 2 is installed in the positioning groove 14. The component 2 is provided with a light source 21 symmetrically from left to right. The light source 21 is an LED lamp. A reflector 4 is installed on the side of the light source component 2 close to the edge of the inner cavity 11. The top of the cup 4 is opened to form a second light outlet 43, and a reflective surface 42 is processed in the reflective cup 4. The reflective surface 42 is a light-condensing structure, and the concave surface of the reflective surface 42 is opposite to the light source assembly 2. The top of the cover 3 protrudes to form a condensing surface 31, and the condensing surface 31 has a hemispherical shell structure. The condensing surface 31 covers the light source 21. A first light outlet 32 is formed on the side close to the reflector 4 , the light entrance 41 corresponds to the first light outlet 32 , and the side of the condensing cover 3 is connected to the side of the reflector 4 close to the light source 21 . The bottom of the photomask 3 is symmetrically provided with a guide portion 33 (see FIG. 5 ), the lower part of the guide portion 33 is chamfered, the center of the guide portion 33 is machined with a through hole 34 that penetrates the upper surface of the condenser cover 3 (see FIG. 7 ), and the bottom of the inner cavity 11 is machined The limit groove 12 corresponds to the guide portion 33.
