LIGHT COLLECTING LENS USED FOR LED ILLUMINATOR WITH COLOR SYNTHESIZING AND LIGHT COLLECTING

摘要

PURPOSE: A light collecting lens used for LED illuminator with color synthesizing and light collecting is provided to increase the transmittance ratio of the light source by forming a hole extended to the LED lighting part. CONSTITUTION: An LED lighting part(10) generates the light source required for the illumination. The condensing lens part(20) of the concave lens shape organizes the hole which perpendicularly passes through the center of the condensing lens part. The LED lighting part and condensing lens part are combined in the adhesive member. The condensing lens part includes the body portion, and the front surface(22) and settling portion(23). The surface of the hall of the condensing lens part includes the first face(25) and the second back side(26). The front surface of the condensing lens part has the curvature of 0-200mm.
