Abstract
A light emitting diode chip or chips array mounted on a substrate is surrounded by one or more side walls. The wall has an uneven reflecting surface to diverge the light emitted from the LED chip or chip array. The wall may have a triangular cross-section so that the emitted light diverges in all directions. When three double-sided reflecting walls surround three LED panels, the reflected light becomes omnidirectional hemispherically and can be used in a light bulb.
