As can be seen in fig. 11, after the light from the lamp beads 32 passes through the reflector 20, the light is obliquely passed through the optical upper cover 40 to form a spot on the ceiling. The reflector 20 is similar to a mirror to form the lamp bead 32 into a mirror image, and all light rays emitted from the reflecting surface 21 are similar to the light rays emitted from the mirror image, so that the optical path length of the light rays is effectively increased, and the cut-off light spot is clearer. That is, the light emitted from the lamp beads 32 is emitted obliquely by the reflector 20, so that the projected light spot becomes wider. In addition, the reflector 20 also serves to turn the light, and the angle formed between the turned light and the horizontal plane is 2θ, and when the vertical distance L of the spot is larger, the angle θ is larger, and the distance H between the lamp bead 32 and the ceiling is larger, the angle θ is smaller. In this way, the optical assembly 100 is reduced in size, making it miniaturized.

As described above, in the optical assembly 100 of the present utility model, the light exit cavity 44 and the light exit hole 41 are provided on the optical upper cover 40, and the reflector 20 is accommodated in the light exit cavity 44, so that the light emitted from the lamp beads 32 can be reflected to the optical upper cover 40 by the inclined reflecting surface 21 formed on the reflector 20 and emitted through the light exit hole 41, and further a light spot matching with the light exit hole 41 can be formed on the ceiling. Compared with the prior art, the lamp 1 of the utility model not only enables the surrounding of the suction top box 200 to have light, so that the space is bright, but also can add different shadows to obtain different light spot effects, has the effects of decoration and decoration, and forms the sky effect at night.
