| Title: |
Arrangement for Spot Illumination |
| Abstract: |
There is provided an arrangement for spot illumination (14). The
arrangement provides an improved collimation and color mixing unit
comprising a LED array (1), a convex shaped reflector (15a), a field lens
(21) and an additional cylindrical reflector (15b) at the exit aperture
of the system. In combination with an optical projection system which may
comprise at least two additional zoom lenses and a gate (in which several
maskers, gobos or shutters could be inserted) the system allows color
mixing in an extended operational range including out of focus zoom
settings often used to get soft edge spots.
