The device assists in fixing the sunshade lens by rotating the fixing ring, and can also facilitate the replacement of the sunshade lens. The sunshade is combined with the sunshade lens to effectively suppress the stray light from affecting the light of the lamp, and the sunshade is threadedly connected to the protective shell so that the sunshade covers the position of the lamp to provide protection;

[0004] However, the device has a retaining ring that is fixed inside the conical cylindrical sunshade. After a second retaining ring that is almost the same size as the sunshade is placed into the sunshade, it is difficult to rotate the second retaining ring because there is no fulcrum on the second retaining ring, whether the second retaining ring is rotated to fix it or the second retaining ring is rotated and removed from the retaining ring, thereby making it difficult to install and remove the sunshade lens. Therefore, a lamp that can reduce stray light is proposed to solve the problem that it is difficult to conveniently install and remove the sunshade lens in existing lamps. Utility Model Content
