[0034] Based on a new embodiment combining the above-mentioned Embodiment 1 and Embodiment 2, with reference to the attached Figure 2a , the reflector 13 is in the shape of a circular ring. The diameter of the light-incident surface of the traditional reflector is smaller than that of the light-emitting surface. When the number of lamp beads is large or the volume is large, the volume of the required reflector is larger. However, the diameter of the light-emitting surface of this reflector 13 is equal to the diameter of the light-incident surface. When the number of lamp beads is large or the volume is large and the volume of the reflector 13 needs to be increased accordingly, the volume change of the reflector 13 is smaller. Or in another embodiment, the circular ring in the middle of the light cutoff cover 1 serves as the installation hole for installing the reflector cup; the diameter of the reflector cup is the same as the diameter of the circular ring; there are various installation methods for the reflector cup: for example, a plurality of buckles for installing the reflector cup are provided at the bottom of the reflector cup; or, a plurality of fixing holes for installing the reflector cup are provided at the bottom of the reflector cup, and it is installed through fixing parts.

One end of the light cutoff piece 11 is connected to the annular outer frame 12, and the other end is connected to the reflector 13; the surface of the light cutoff cover 1 is a plated mirror surface, so the inner walls of the area 14 surrounded by the light cutoff pieces 11 are all mirror surfaces. The beneficial effect of this embodiment is that the outer surface of the light cutoff piece 11 and the inner wall of the annular outer frame 12 do not absorb the light emitted by the light source and will not cause a large loss of the light emitted from the light source; since the outer surface of the light cutoff piece 11 is a mirror surface, the light cutoff piece 11 can prevent light leakage between two adjacent areas 14 and at the same time make the reflected light blocked by the light cutoff piece 11 gather in the same direction, making the light emitted by the light source more concentrated.
[0036] As a new embodiment, with reference to the attached Figure 2b, the lower surface 112 of the light cutoff sheet 11 and the lower surface 121 of the annular outer frame 12 are in the same plane.

When the distance of the light cutoff cover 1 is closer, the boundary line is more obvious; when the distance of the light cutoff cover 1 is farther, the boundary line is more blurred; if the upper surfaces of the reflector 13, the light cutoff sheet 11 and the annular outer frame 12 are not all in the same plane, it will affect the installation of the light output lens. The beneficial effect of this embodiment is that it is convenient for the installation of the light output lens or other effect sheets of the lamp, so that there will be no obstruction during installation.

When the distance of the light cutoff cover 1 is closer, the dividing line is more obvious; when the distance of the light cutoff cover 1 is farther, the dividing line is more blurred; if the upper surfaces of the reflector 13, the light cutoff film 11 and the annular outer frame 12 are not all in the same plane, it will affect the installation of the light-emitting lens. The beneficial effect of this embodiment is that it is convenient for the installation of the light-emitting lens or other effect films of the lamp, so that there will be no obstruction during installation.
