Vehicle lamp, has coupling unit with optical waveguide units that are formed with ellipsoidal surface with two focuses and coupled in series by coupling part

摘要

The lamp has a light guidance (24) in the form of a coupling unit (U1). The coupling unit has optical waveguide units (25), formed with an ellipsoidal surface with two focuses and coupled in series by a coupling part. A light emission part of a light emitting diode (LED) (28) is placed close to the focuses at ends of the coupling unit.
