ABSTRACT:
A multidirectional light emitting diode unit includes a light emitting diode chip configured to emit light from at least one side of the chip when powered. An at least translucent casing extends from at least the one side of the light emitting diode chip. A distal end of the casing has at least two protrusions. Each protrusion has a substantially flat distal end surface facing outwardly away from the light emitting diode chip and inwardly toward a centerline of a cylindrical sidewall to form a recess between the protrusions within the distal end of the casing. Light from the light emitting diode chip is internally reflected by the sidewall and directed outwardly from the casing through the flat surfaces along output directions normal thereto.
