Patent attributes
A sideway-emission light emitting diode includes a light emitting diode package comprised of a light emitting diode dice that gives off light and a lens that is positioned in front of a front end face of the package for receiving the light and redirecting the received light toward a circumference of the package and a light guide comprised of a board defining a cavity to receive and retain the light emitting diode package therein. The board has opposite sides each forming a cut-off delimited by opposite inclined edges, a refraction section extending from each inclined edge, and a projection section formed between opposite refraction sections, whereby light transmitting into the light guide is directed, by means of the reflection/refraction by the inclined edges, the refraction sections and the projection sections, toward and projected from the projection sections in sideway directions.
