Optical element and light distributing module

A light distributing module, comprising:

• an optical element and a reflector, wherein:
• the optical element comprises an optical element body provided with a light incident surface and a light emergent surface,
• the optical element body is provided with a second reflective surface peripherally arranged along the light emergent surface;
• the second reflective surface and the light emergent surface form a cavity, and a light source is arranged in the cavity;
• the light incident surface is attached to a top of the light source;
• along a diameter direction of the light emergent surface, the light emergent surface comprises a first transparent surface, a frosted surface, and a second transparent surface, which are connected in sequence, the frosted surface is formed as a flat surface, a first angle formed between the first transparent surface and the frosted surface is an obtuse angle, and a second angle formed between the frosted surface and the second transparent surface is an obtuse angle, wherein the frosted surface is frosted such that each of two ends of the frosted surface forms a cut-off line with diagonal ends of a light exit of the reflector and an included angle between two cut-off lines is less than a threshold angle, the light emergent surface is attached to a light entry of the reflector and the light entry is an end of the reflector that is away from the light exit.
