Abstract
A photoflash unit comprising a linear array of photoflash lamps mounted on a printed circuit board disposed within the longitudinal channel of an elongated housing member having an enclosing cover panel of light-transmitting material. The housing channel has a semi-rectangular cross-section and reflective surfaces on the sidewalls adjacent the flashlamps. A flat sheet of material, such as white paper adhesively coated on one side, is secured to the circuit board and interposed between the lamps and the circuitry for reflecting heat and light away from the circuit board and insulating at least portions of the circuitry from the radiant output of the lamps.
