In a projector assembly having a lamp for emitting light, and an ellipsoid reflector for capturing the light, the ellipsoid reflector having a opening through it s vertex facilitating placement of the lamp, there is provided an improvement wherein the opening in the ellipsoid reflector is sized to allow a major portion of cooling air to pass therethrough into a region defined by the ellipsoid reflector. An air deflector is situated in the opening so as to facilitate distribution of cooling air along the lam p and outwardly towards the inside surface of said ellipsoid reflector from within said region.
