The invention belongs to the technical field of lenses, and particularly relates to a lens, a backlight module and terminal equipment, the lens comprises a lens main body and a reflector, and the lens main body is provided with a reflection cavity for accommodating the reflector; a refracting surface which is at least used for refracting and reflecting light entering from the bottom of the lens main body to the position above the lens main body is formed on the outer wall of the peripheral side of the lens main body, and a first reflecting surface which is at least used for reflecting the light entering from the bottom of the lens main body to the peripheral side of the lens main body is formed on the cavity wall of the reflecting cavity of the reflecting body. The refracting surface is formed on the outer wall of the peripheral side of the lens main body, so that part of light incident from the bottom of the lens main body can be refracted to the area above the lens through the top surface of the lens and th
