Abstract

Certain aspects of the invention may be found in an SLED with an improved luminance dispersion diagram. In one embodiment of the invention, an SLED may include a light-emitting element of solid geometry comprising a p-n junction. The light emitting element of solid geometry may enable distribution of light energy that is multidirectional. The light-emitting element may emit light from substantially its entire surface. The SLED may further include at least one pair of electrodes for coupling the light-emitting element of solid geometry to a source of electricity. The SLED may further include a lens of solid geometry enclosing the light-emitting element and at least a portion of the at least one pair of electrodes. The light-emitting element of solid geometry may include a sphere and/or a cube. The p-n junction may include at least one semiconductor layer disposed on a surface of the light-emitting element of solid geometry.
