Abstract
A multi-lamp shadowless illumination system which has a plurality of sealed lamp housings and a lamp tiltably mounted in each lamp housing. The lamp housings are mounted on a lamp holding pipe means in a generally horizontal array and in positions with the axes of the lamps directed toward a light axis depending perpendicularly from the central point of the array of lamp housings, the lamps within said housings being tiltable around axes which are perpendicular to the light axis. Operating rods are movable linearly within the pipe means and have one end operatively coupled with the respective lamps for tilting the lamps. Gear means is coupled to the operating rods for driving the rods for simultaneously tilting the lamps to move the focal point of the beams of light from the lamps along the light axis.
