  • Patent number: 7901113
    Abstract: The present invention relates to a side illumination lens and a luminescent device using the same, and provides a body, a total reflection surface with a total reflection slope with respect to a central axis of the body, and a linear and/or curved refractive surface(s) formed to extend from a periphery of the total reflection surface; and a luminescent device including the lens. According to the present invention, a lens with total internal reflection surfaces with different slopes, and a linear and/or curved refractive surface(s) allows light emitted forward from a luminescent chip to be guided to a side of the lens. Further, a linear surface(s) formed in a direction perpendicular or parallel to a central axis of a lens and a curved surface are formed on an edge of the lens so that a process of fabricating the lens is facilitated, thereby reducing a defective rate and fabrication costs of the lens.
