摘要： The invention relates to the reduction of the divergence of a light beam (BB1) emitted by a resonant cavity light emitting diode (10), said beam (BB1) being emitted in a direction (SZ). Light emitted by the resonant cavity light emitting diode (10) is directed substantially towards said direction (SZ) by a reflecting surface (20). According to the present invention, the height (H1) of said reflecting surface (20) with respect to the level of the active surface (11) of said resonant cavity light emitting diode (10) is smaller than or equal to the diameter (DIA1) of said active surface (11) of said resonant cavity light emitting diode (10) multiplied by a factor of 1,5. Advantageously, the reflecting surface (20) has the form of a truncated cone.
