    摘要： Disclosed herein is a Light Emitting Diode (LED) light source lens for emitting light in a lateral direction. The LED source lens includes an upper part, an upper part and a central part. The upper part includes an upper part reflecting surface bent symmetrically with respect to the central axis of the lens, and an upper part refracting surface extended from the end of the upper part reflecting surface parallel with the central axis. The central part includes a side surface extended from the lower end of the upper part refracting surface and bend inwards, and refracts or reflects light through the side surface. The lower part accommodates the LED light source, and includes an arch-shaped lower part refracting surface extended outwards from the lower end of the side surface of the central part. The light radiated from the LED light source is emitted perpendicular to the central axis.

    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.

    摘要： A lens for light emitting diode (LED) light sources which allows light emitted from an LED light source to exit the lens in a direction perpendicular to a vertical center axis of the lens. The lens of the present invention includes an inner space which is defined in a lens body having both a bottom surface and an upper reflective surface, so that light passing through the inner space is partially reflected by total internal reflection on a portion (selective transmission surface, inner reflective surface, inside reflective surface) of a boundary surface between the inner space and the lens body. Thus, light emitted from an LED light source efficiently exits the lens through a side surface. Accordingly, the lens of the present invention is used in efficient display and illumination optical systems.
