Abstract
An LED is provided, the LED comprising a lighting assembly and a light bead. The light head encases the lighting assembly. A cross-section of an upper portion of the light bead is an asymmetric shape with respect to the projection of a normal of the lighting assembly on the cross-section of the upper portion of the light bead, while a cross-section at the lower portion of the light bead perpendicular to the axis is a symmetric shape with respect to the projection of the normal of the lighting assembly on the cross-section at the lower portion of the light bead. The lighting assembly is located at a symcenter of the lower portion of the light bead. The aforementioned LED can increase its visible range, and can ensure an even distribution of the internal stress surrounding the lighting assembly. An LED packaging method is also provided.
