Optical lens

An optical lens for covering a light emitting unit, the optical lens comprising:

• a first lens body, including:
• a first light exiting surface;
• a second light exiting surface;
• a first light incident surface and a second light incident surface that oppose the first light exiting surface;
• a third light incident surface opposing the second light exiting surface;
• and
• a bottom surface connected to the first light incident surface, the second light incident surface and the third light incident surface;
• wherein the first light incident surface, the second light incident surface and the third light incident surface are sequentially connected to form on the bottom surface a groove configured to receive the light emitting unit;
• a second lens body connected to the first lens body, and including:
• an outer circumference surface connected to the second light exiting surface;
• and
• a first inner circumference surface and a second inner circumference surface that oppose the outer circumference surface;
• wherein the first inner circumference surface is connected to the bottom surface and the third light incident surface, and wherein the first inner circumference surface and the second inner circumference surface are connected to each other to form a cavity;
• and
• a mounting body surrounding and connected to the first lens body and the second lens body, and extending outward with respect to the first lens body and the second lens body.
