Abstract
Disclosed herein is an illumination system for use in display systems employing spatial light modulators. The illumination system comprises a fastening mechanism for securing the bonding of the walls of the light integrator of the illumination system. A heat dissipation mechanism can be alternatively provided for reducing the temperature of the illumination system by dissipating the heat thereof.
