Abstract (en)
[origin: WO2013086694A1] A lamp (10) includes at least two light emitting diodes (12, 40) in thermal communication with a heat sink. A translucent envelope (14) receiving light emitted from the light emitting diodes (12, 40) is also provided. A light guide (16) is located to receive light emitted from at least one of the light emitting diodes (12). The light guide (16) includes a first leg extending away from the heat sink toward an interior of the envelope (14) and a light emitting second leg angled relative to the first leg. The second leg can be at least substantially perpendicular to a longitudinal axis of the lamp (10).
