DIPOLAR SIDE-EMITTING LED LENS AND LED MODULE INCORPORATING THE SAME
First Claim
1. A dipolar Light Emitting Diode (LED) lens comprising:
- an upper hemisphere-shaped base housing an LED chip therein and adapted to radiate light from the LED chip to the outside;
a pair of symmetric reflecting surfaces, each reflecting surface having a proximal end placed on top of the base and a distal end extended upward and away from the base, with the proximal ends of the reflecting surfaces meeting each other in the form of a joint line on the top of the base, forming a V-shaped valley extended along the joint line between the reflecting surfaces, whereby light from the LED chip is reflected by the reflecting surfaces in a dipolar pattern symmetric about the joint line; and
a pair of symmetric radiating surfaces placed outside the reflecting surfaces, respectively, to radiate light from the reflecting surfaces to the outside, thereby forming a peanut-shaped light radiation pattern.

Abstract
The present invention relates to a dipolar LED and a dipolar LED module incorporating the same, in which an upper hemisphere-shaped base houses an LED chip therein and adapted to radiate light from the LED chip to the outside, and a pair of reflecting surfaces placed at opposed top portions of the base in a configuration symmetric about an imaginary vertical plane. The vertical plane passes through the center of the LED chip perpendicularly to a light-emitting surface of the LED chip. The reflecting surfaces are extended upward away from the top portions of the base to reflect light from the LED chip away from the imaginary vertical plane. A pair of radiating surfaces are placed outside the reflecting surfaces, respectively, to radiate light from the reflecting surfaces to the outside. In this way, light emission from the LED chip can be concentrated in both lateral directions.
