ABSTRACT:
Reflecting coating means are provided to replace the conventional reflector cavities surrounding each photoflash lamp of a multilamp photoflash array. A reflective adhesive coating for this purpose can be applied to each photoflash lamp around a portion of the lamp circumference to reflect the light outwardly in a desired direction. A reflective adhesive coating can also be applied to the circuit board member used with a photoflash lamp array to provide sequential firing of flash lamps as an alternate means to provide the desired light reflection and without need for individual lamp processing in achieving this result. The coating material comprises light reflective particulate solids bonded to the substrate with an adhesive binder.
