    • A photoflash unit comprising a plurality of 2n flashlamps attached to a printed circuit board and disposed in a linear array with the longitudinal axes of respective lamps aligned in parallel. The circuit board has a substantially rectangular portion with n spaced apart extensions projecting vertically from a longer side thereof, the extensions being located behind alternate lamps of the linear array. Each extension contains portions of circuit patterns bridged by a mass of switch material to provide a solid state radiation switch on each extension and adjacent to a respective lamp for receiving radiant energy emitted by that lamp. The unit further includes a plurality of reflector cavities within each of which a respective one of the flashlamps is nested. Each reflector cavity includes a recessed rear wall section for accommodating a circuit board extension, such that each of the extensions are disposed between a respective lamp envelope and the recessed rear wall of the associated reflector. With the lamp contiguous with an upper portion of each reflector cavity and each circuit board extension contiguous with a recessed lower portion of a respective cavity, substantially equal predetermined spacings are maintained between the switches of the n extensions and the alternate lamp envelopes associated therewith.
    • 一种闪光灯单元,包括多个2n个闪光灯,其附接到印刷电路板并且设置成线性阵列,其中各个灯的纵向轴线平行排列。 电路板具有基本上矩形的部分,其中n个间隔开的延伸部从其较长侧垂直伸出,该延伸部位于线性阵列的交替灯之后。 每个延伸部包含由大量开关材料桥接的电路图案的部分,以在每个延伸部分上提供固态辐射开关,并且邻近相应的灯以接收由该灯发射的辐射能。 该单元还包括多个反射器空腔,每个反射器腔中的相应一个闪光灯被嵌套。 每个反射器腔包括用于容纳电路板延伸部的凹陷后壁部分,使得每个延伸部分设置在相应的灯壳和相关联的反射器的凹入的后壁之间。 随着灯与每个反射器腔的上部相邻并且每个电路板延伸部与相应空腔的凹陷的下部相邻,在n个延伸部的开关和与其相关联的备用灯泡信封之间保持基本相等的预定间隔。

    • A photoflash unit comprising a plurality of 2n flashlamps attached to a printed circuit board and disposed in a linear array with the longitudinal axes of respective lamps aligned in parallel. Circuit patterns on the circuit board include a plurality of n selective terminal means, each associated with a respective pair of the lamps and connected to one lead-in wire of each of the lamps of the associated pair, and a common terminal associated with all of the 2n lamps but directly connected to the other lead-in wire of one lamp of each pair. The circuit board has a substantially rectangular portion with n spaced apart extensions projecting vertically from a longer side thereof, the extensions being located behind alternate lamps of the linear array. Each extension contains portions of the circuit patterns spaced apart to form predetermined gaps, and a mass of switch material is disposed on each extension to bridge the gap between circuit patterns to thereby provide a solid state radiation switch on each extension behind and adjacent to a respective lamp for receiving radiant energy emitted by that lamp. In this manner, a respective normally open switch on each circuit board extension is coupled between the common terminal and a lead-in wire of the other lamp of each pair of lamps, so that the n normally open switches are coupled between the common circuit lead-in wire of associated pairs of the 2n lamps.
