Abstract
A particle-containment shield is provided. The particles-containment shield includes a containment structure that defines an air inlet to receive air heated by a projection lamp from the outlet of the projection-lamp module and defines an air outlet to vent air heated by the projection lamp away from the projection lamp. The containment structure is sealed intermediate the air inlet and the air outlet such that air heated by the projection lamp that enters through the air inlet exits the containment structure through the air outlet. The containment structure defines a length, a width, and a height of the particle-containment shield. The particle-containment shield includes one or more deflection members is arranged in the containment structure to collectively block all straight line paths from the air inlet to the air outlet so as to inhibit projection lamp particles from exiting the air outlet upon projection lamp rupture.
