Abstract:
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.
