Luminous of reflection lens

The utility model discloses a luminotron of reflection lens which relates to a luminous diode device making a big diverging angle and high efficiency in the field of photoelectric device. The luminotron of reflection lens is composed of a base, a luminotron chip, and a reflection lens. The luminotron of reflection lens adopts the reflection lens whose front end is processed into a concave conical surface and whose outside is processed into an upper cone or a lower cone constitutional formula to realize the goals that light outgoes a big diverging angle and intensity of light is relative uniform in a relatively great spatial angle and extracting light efficiency is high. The utility model also has the advantages of convenient reflection lens manufacturing structure, easy changing diverging angle size, low cost, etc, and the luminotron of reflection lens is in particular suited to be a serial big diverging angle luminous device of different diverging angles.
