HIGH INTENSITY LIGHT SOURCE ABSTRACT OF THE DISCLOSURE A reflective tunnel of rectangular cross-section with opposing parallel or converging, opposing sides has a light diffuser located at the output opening of the tunnel for integrating the light passing therethrough and a densitometer located near the input opening of the tunnel for measuring the composition of the light within the tunnel. A lamp is positioned at the inner focal point of each of a plurality of dichroic elliptical reflectors which are supported at the input opening of the tunnel so that light emitted by each lamp is projected into the tunnel directly toward the light diffuser. The lamps are symmetrically disposed about the optical axis of the reflective tunnel and the reflector axes intersect the axis of the reflective tunnel at a point which is located between the midpoint of the reflective tunnel and the output of the tunnel. In a preferred embodiment, compensating means are located in a plane defined by the outer focal points of the elliptical reflectors to compensate for variations in the reflector/lamp alignment. - 1 -
