A CONDENSING LENS HAVING A OVAL-SHAPE LIGHT EMITTING

摘要

PURPOSE: A condensing lens for LED is provided to remove an additional filter and the like by using an oval light emission profile instead of a circular light emission profile. CONSTITUTION: A condensing lens(100) for LED comprises a first lens part, a second lens part, and a light emission side (400). The first lens part includes a first incident side which is convex toward an LED(500). The second lens part a second incident side(122) for receiving the peripheral light and a reflective side(123) for totally reflecting the curved incident light refracted from the second incident side. The light emission side is formed to emit the light from the first incident side of the first lens part and the reflective side of the second lens part. The first incident side is formed to surround an upper direction of the LED and the second incident side is formed to surround a lateral direction of the LED. The second incident side is inclined from the direction perpendicular to the first incident side to the LED. The first incident side is formed with an oval structure.
