Lens and Lamp with Lens Thereof

A lens (100), comprising:

• light source setting location (103), being with a main optical axis (104), a longitudinal axis (105), and a horizontal axis (106) passing through its center and perpendicular to each other;
• first portion (101) and second portion (102), located in the plane where the main optical axis (104) and the horizontal axis (106) are located, respectively, on both sides of the main optical axis 104;
• the light from the light source (200) arranged at the light source setting location (103) forms a first beam (201) after the light distribution of the first portion (101), and the reverse extension line of the maximum light intensity direction of the first beam (201) intersects the main optical axis (104);
• characterized in that, the second portion (102) comprises:
• first light inlet surface (1021);
• first connection surface (1022), which is connected to an outer end of the first light inlet surface (1021);
• first total reflection surface (1023), being inclined outwardly relative to the main optical axis (104), which is used to reflect the incident light from the first light inlet surface (1011) outwardly;
• second total reflection surface (1024), being inclined outwardly relative to the main optical axis (104), and one end is connected with the free end of the first connection surface (1022) for receiving and reflecting the reflected light from the first total reflection surface (1023);
• third total reflection surface (1025), being inclined inwardly inward relative to the main optical axis (104), and one end is connected with the free end of the second total reflection surface (1024) for completely reflecting the reflected light from the second total reflection surface (1024);
• and first light outlet surface (1026), being connected to the free end of the first total reflection surface (1023) and the third total reflection surface (1025), and emitting the reflected light emitted from the third total reflection surface (1025), and the maximum optical intensity direction of the second light beam (202) emitted from the first light outlet surface (1026) intersects with the main optical axis (104).
