Patent ID: 6997580

Claim:
A multidirectional light emitting diode unit, comprising: a light emitting diode chip configured to emit light from at least one side of the chip when powered; and an at least translucent casing extending from at least the one side of the light emitting diode chip, the casing having a distal end opposite and most remote from the one side of the light emitting diode chip and a substantially cylindrical sidewall extending up to the distal end, the distal end of the casing having at least two protrusions, each protrusion having a substantially flat distal end surface facing outwardly away from the light emitting diode chip and inwardly toward a centerline of the cylindrical sidewall to form a recess between the protrusions within the distal end of the casing, wherein 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.
