ABSTRACT:
The present invention discloses an aspherical LED angular optical lens for narrow distribution patterns and an LED assembly using the same. The optical lens comprises a concave surface on a source side and a convex surface on a project side. The LED assembly comprising the optical lens can accumulate light emitted from the LED die and generate a peak intensity of the narrow angular circle distribution pattern which is greater than 15° and smaller than 30°. The present invention only uses a single optical lens capable of accumulating light and forming a required distribution pattern to satisfy the requirement of a luminous flux ratio greater than 85% and the requirement of an illumination, a flash light of a cell phone or a flash light of a camera.
