The assembly comprises a quartz-halogen lamp, having an internal reflector and an enlarged base removably mounted in the projector, and a lens holding bracket removably mounted in the projector in alignment with the lamp. The bracket is resiliently pivoted toward the lamp and has a tab for striking the lamp base to retain the lens at a predetermined distance from the lamp.
