Example Embodiment

[0007] Depend on figure 1 It is well known that the light distribution mirror cover of this embodiment has a structure to prevent cracking, and the mold of the injection molding machine is molded and injected, and the light distribution mirror 1 and the injection molded light distribution mirror 2 will be integrated with each other. A flange structure 3 is added around the mirror. The size of the rib is 1 mm×1mm. The injection molded light distribution mirror 2 has a groove, and the light distribution mirror flange 3 is inserted into the groove of the injection molded light distribution mirror 2. During production and use During the process, the lamps and lanterns will be affected by forces from various aspects. The structure light distribution mirror of the present invention is red 2, and the injection molding light distribution mirror 2 is white. This structure reduces product cracking, improves product quality and qualified rate, and reduces cost.
