Abstract
A multilamp photoflash unit includes a housing member having a plurality of lamp-receiving cavities of a relatively opaque material with a reflective surface adjacent the lamp whereby back radiation from the lamp is reduced. Also, a reflector having cavities of opaque pigmented plastic resin material and a reflective surface may be disposed within a plastic housing and serve to inhibit back radiation from a lamp.
Claims3
A photoflash array having a housing member containing a reflector unit which includes at least one cavity formed to receive a flashlamp and characterized by the improvement wherein said cavity includes a pair of spaced sidewalls with a reflective material on said pair of spaced sidewalls substantially normal to the opening thereof and on the surface thereof immediately adjacent said flashlamp and is formed from a relatively opaque pigmented plastic resin material selected from the group consisting of carbon black and titanium dioxide whereby back radiation of light energy is inhibited.
A photoflash array having a housing member which includes a back portion and a light transmitting front portion, said back portion having at least one cavity therein formed to receive a flashlamp, said cavity of said housing member having a reflective surface immediately adjacent said flashlamp and characterized by the improvement wherein a pair of spaced sidewalls are substantially normal to the opening of said cavity and a relatively opaque pigmented plastic resin material selected from the group consisting of carbon black and titanium dioxide is used to form said cavity of said back portion.
