Flashlamp unit

A flashlamp unit for cooperating with an associated reflector having an elongated slot, the elongated slot having reflective surfaces on each elongated side disposed about a first plane and associated indexing means, said unit comprising:

• a module which includes a plurality of flashlamps each having a longitudinal axis and a support having a geometric center carrying said flashlamps arranged in fixed predetermined relationship to each other, said support including a first planar generally disk shaped member with each of said flashlamps carried thereon with the longitudinal axis thereof (a) in a second plane which is parallel and spaced from said disk and (b) in radial relation to the geometric center of said support, said member extending over at least half of each of said flashlamps to provide support and being translucent, said module having a thickness which is substantially equal to the largest transverse dimension of one of said flashlamps, said module including means for cooperating with the associated indexing means to selectively position one of said flashlamps proximate the associated reflector, said second plane and the first plane being generally coplanar when said module is cooperating with the reflector.
