reflection surface and then is also projected from the cone mouth the reflection surface lens in this invention integrates multiple functions within the one body including focusing refraction and reflection which allows uniform illumination and other desired illumination effects without the need for any reflective coating it simplifies the processing technique of led illumination systems and reduces processing costs application_number US 201214371192 A description the following description along with the figures and application examples are given by way of example only and shall not be used to limit the derivative types of this invention as shown in fig8 and fig9 the first refraction groove 1 and the second refraction groove 2 are respectively set on both ends of the reflection lens which are on the same central axis and are both in a cylindrical shape lens shell 4 is translucent and outer surface 41 is in a cone shape the cone mouth points from the first refraction groove 1 to the second refraction groove 2 reflection surface in multiple sections 3 is set on the outer surface 41 when an led is positioned in the first refraction groove 1 the light emitted from it is refracted by the first refraction groove 1 and projected through the cone mouth where the second refraction groove 2.
