Abstract
A light-emitting diode including a casing with two flat outer light-emitting opposite parallel sides connected by a curved outer surface.
Claims13
In a light-emitting diode structure including a housing formed of a plastic material and having a light-emitting surface, and a semiconductor light-emitting diode embedded in said housing opposite and spaced from said light-emitting surface, the improvement wherein:
- said plastic housing has a rectangular cross section formed by first and second pairs of opposed parallel flat outer side surfaces;
- and said light-emitting surface is an outwardly curved end surface of said housing which extends to each of said side surfaces and is curved so that its surface area presents an area of uniform brightness to an observer.
