Abstract: A triggering transformer having windings surrounding a photographic flash tube fires the latter when the transformer primary winding is energized by the closure of a switch. This switch closure also turns off a transistor which then unblocks a light sensitive integrator including an LASCR which receives the flash tube light by reflection. When the integrator has received a predetermined quantity of light, the LASCR turns on and energizes the primary winding of a second triggering transformer having windings surrounding a quench tube connected in parallel with the flash tube. This fires the quench tube which in turn extinguishes the flash tube.

Abstract translation: 当变压器初级绕组由开关闭合而被激励时，具有围绕照相闪光管的绕组的触发变压器使后者触发。 该开关闭合还关闭晶体管，然后晶体管解除阻挡包括通过反射接收闪光管的LASCR的光敏积分器。 当积分器已经接收到预定量的光时，LASCR导通并激励具有围绕与闪光管并联连接的骤冷管的绕组的第二触发变压器的初级绕组。 这会引发骤冷管，这又会使闪光管熄灭。
