Abstract
A battery-powered electronic strobe flash apparatus has a flashtube, which produces radiation in proportion to the energy delivered to it. A transformer has a primary winding, connectable to the battery, for storing energy in the transformer and a secondary winding, connected to the flashtube, for delivering the stored energy to the flashtube when the primary winding is disconnected from the battery. An actuatable switch has a first condition for connecting the battery to the primary winding to saturate the transformer, and a second condition for disconnecting the battery from the primary winding, thereby causing a substantially constant amount of energy to be delivered to the flashtube, whereby a substantially constant amount of flashtube radiation is produced each time the switch is actuated.
