<p>A light emitter with several semiconductor bodies (10, 20, 30), each with an active zone (11, 12, 13) and emitting light with different central wave-lengths (L10, L20, L30) and spectral bandwidths (DL10, DL20, DL30) in which in at least one body (10) the emission wavelength (L10) in zone (11) varies in a given way and the bandwidth of the emitted light (DL10) is increased.</p> |
