A secondary internal reflective lens and an LED lamp using the lens. The lens (130) comprises a light-in surface (131), a first reflective surface (132) opposite to part of the light-in surface (131), a second reflective surface (133) opposite to the first reflective surface (132), and a light-out surface (134) opposite to the second reflective surface (133). Incident light is injected to the lens (130) from the incident surface and is then projected to the first reflective surface (132). The first reflective surface (132) reflects the light projected thereon to the second reflective surface (133). The second reflective surface (133) reflects the light projected thereon to the light-out surface (134). The light projected to the light-out surface (134) is ejected out of the lens (130) by the light-out surface. The lamp uses the lens to perform secondary reflection on injected lamp light, thereby making the incident light more uniform, and reducing the dazzling degree of the LED lamp using the lens. |
