Abstract
A lens has a plurality of first, second, and third optical regions. The first, second and third optical regions are arranged in sequential order. Space angle defined between each first, second, and third optical region and an optical axis of the lens are different from each other. Each first, second and third optical region includes a refracting surface and a reflecting surface which are arranged in different planes. The invention also relates to an LED module having the lens described above.
