LED LIGHT DISTRIBUTION LENS, LED LIGHTING MODULE HAVING THE SAME, AND LIGHTING FIXTURE WITH THE LED LIGHTING MODULE

摘要

PROBLEM TO BE SOLVED: To provide an LED light distribution lens capable of achieving light distribution as designed, to provide an LED lighting module with the LED light distribution lens, and to provide a lighting fixture with the LED lighting module.;SOLUTION: The LED light distribution lens 1 has a light emitting surface 2 which emits forward light from an LED 6 disposed in its center and whose shape is circular in its plan view. The LED light distribution lens is characterized by the construction of the emitting surface which has a plurality of convex surfaces formed both in its radial and its circumferential directions in such a manner that the convex surfaces surround the circumference of the LED, with the LED as a center, and has continuous surfaces formed such that the boundaries of the convex surfaces constitute concave surfaces.;COPYRIGHT: (C)2011,JPO&INPIT
