Abstract
A compact flash lamp array includes a housing defining a plurality of cavities, each cavity having a light emitting opening and an exhaust vent and containing a combustible mass. A transparent cover is fixed over the light emitting opening and means are provided for individually firing the combustible mass in each cavity. A valve cooperating with the exhaust vents opens the exhaust vent of a cavity in which a combustible mass is fired and closes the cavities containing unfired combustible masses.
Claims17
A compact flash lamp array, comprising:
- a) a housing defining a plurality of cavities, each cavity having a light emitting opening and an exhaust vent;
- b) a transparent cover fixed over the light emitting opening;
- c) a combustible mass deposited in each cavity;
- d) means for individually firing the combustible mass in each cavity;
- and
- e) a rotary valve cooperating with the exhaust vents for opening the exhaust vent of a cavity in which a combustible mass is fired and closing the cavities containing unfired combustible masses.
A compact flash lamp array, comprising:
- a) a housing defining a plurality of cavities, each cavity having a light emitting opening and an exhaust vent;
- b) a transparent cover fixed over the light emitting opening;
- c) a combustible mass deposited in each cavity;
- d) means for individually firing the combustible mass in each cavity;
- e) valve means cooperating with the exhaust vents for opening the exhaust vent of a cavity in which a combustible mass is fired and closing the cavities containing unfired combustible masses;
- and
- a venting chamber in communication with each exhaust vent, wherein the venting chamber defines an opening to the atmosphere and further comprising a filter over the opening, wherein the filter is a porous ceramic.
A compact flash lamp array, comprising:
- a) a housing defining a plurality of cavities, each cavity having a light emitting opening and an exhaust vent;
- b) a transparent cover fixed over the light emitting opening;
- c) a combustible mass deposited in each cavity;
- d) means for individually firing the combustible mass in each cavity;
- and
- e) valve means cooperating with the exhaust vents for opening the exhaust vent of a cavity in which a combustible mass is fired and closing the cavities containing unfired combustible masses, wherein a component of the valve means is integral with a camera body, wherein the flash lamp array is an integral part of a single use camera, and wherein the flash array is a circular array having a venting chamber in the center of the array, and the component of the valve means on the camera comprises a rotary valve.
A compact flash lamp array, comprising:
- a) a housing defining a plurality of cavities, each cavity having a light emitting opening and an exhaust vent;
- b) a transparent cover fixed over the light emitting opening;
- c) a combustible mass deposited in each cavity;
- d) means for individually firing the combustible mass in each cavity;
- and
- e) valve means cooperating with the exhaust vents for opening the exhaust vent of a cavity in which a combustible mass is fired and closing the cavities containing unfired combustible masses, further comprising means moveable relative to the housing for activating the individual firing means, and means responsive to relative motion of the activating means and the housing means for activating the valve means.
