LED ILLUMINATION SYSTEM WITH POLARIZATION RECYCLING
A light engine has a light source front surface that emits non-collimated light. A collection lens collects the non-collimated light and provides incompletely collimated light. A collimating lens receives the incompletely collimated light and provides a collimated image. A non-orthogonal polarizing...

| description | A light engine has a light source front surface that emits non-collimated light. A collection lens collects the non-collimated light and provides incompletely collimated light. A collimating lens receives the incompletely collimated light and provides a collimated image. A non-orthogonal polarizing filter receives the collimated image and passes a polarized portion of the collimated image as a direct component of the polarized light engine image. The non-orthogonal polarizing filter reflects a recycled image back to the front surface. The non-orthogonal shape of the polarizing filter is selected according to the pattern of light on the light source front surface.
L'invention concerne un moteur de lumière qui possède une surface avant de source de lumière qui émet de la lumière non collimatée. Une lentille de collecte collectant la lumière non collimatée et fournissant une lumière collimatée de manière incomplète. Une lentille de collimation reçoit la lumière collimatée de manière incomplète et fournit une image collimatée. Un filtre de polarisation non orthogonal reçoit l'image collimatée et passe une partie polarisée de l'image collimatée en tant que composante directe de l'image de moteur de lumière polarisée. Le filtre de polarisation non orthogonal réfléchit l'image recyclée en retour vers la surface avant. La forme non orthogonale du filtre de polarisation est sélectionnée conformément au motif de lumière sur la surface avant de source de lumière. |
