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. De façon plus spécifique, la présente invention fournit une source claire et efficace de lumière polarisée. La configuration selon l'invention est compacte et efficace, et elle a une étendue particulièrement faible.
