Abstract

D'une façon générale, la présente invention se rapporte à des sources d'éclairage à base de semi-conducteurs à large bande et à des projecteurs d'images à large bande qui utilisent une couche ou un matériau à base de phosphore qui est pompé ou excité par une lumière provenant d'une ou de plusieurs LED. La configuration selon l'invention est compacte et efficace, et elle a une étendue particulièrement faible.
