    摘要： 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.
