Flashlamp disk containing internal reflectors

In a flashlamp unit including a disk-shaped, light-transmitting housing having a central axis, and a plurality of flashlamps each having a longitudinal axis and arranged within said housing in a radial pattern about said central axis such that said longitudinal axes of said flashlamps pass through said central axis, wherein said flashlamp unit is adapted for cooperating with an indexing means for rotating said housing about said central axis to selectively position each of said flashlamps at a first, stationary location with respect to said indexing means, the improvement comprising:

• a plurality of reflectors, each of said reflectors including first and second substantially planar reflective members positioned within said disk-shaped housing adjacent a respective one of said flashlamps and on opposing sides thereof for reflecting a portion of the light emitted from said flashlamp upon ignition thereof through the peripheral region of said light-transmitting housing and for preventing sympathetic ignition between said flashlamp and flashlamps adjacent thereto.
