DEFINITION

Classification: 362/3

(under the class definition) Subject matter comprising means to illuminate a subject and designed for use with a device (camera) for recording an image of the subject on photosensitive material and not classifiable elsewhere.

(1) Note. This and the indented subclasses include subcombinations adapted to perfect the illumination function such as a "flashgun" designed to give a short burst of high intensity light when used with an unclaimed shutter actuator.

SEE OR SEARCH THIS CLASS, SUBCLASS:

257+, for light projectors of general illumination utility including "photo flood lights" which fail to require structural features that would limit them to a photos:graphic environment.

SEE OR SEARCH CLASS

174, Electricity: Conductors and Insulators, 250+, for a printed circuit board, per se.

219, Electric Heating,

260+, for resistive element igniters.

313, Electric Lamp and Discharge Devices, appropriate subclasses for photoflash bulbs, per se, of the nonconsumable type.

315, Electric Lamp and Discharge Devices: Systems, appropriate subclasses for systems including circuit means for energizing light sources of the nonconsumable type.

361, Electricity: Electrical Systems and Devices,

243+, for electrical systems for igniting combustible flashbulbs of general utility and wherein the flashbulbs are not limited by specific structure. See the reference to Class 431 below.

396, Photography,

155+, for combinations of photos:graphic lights and significant camera structure which may include photoelectric means.

399, Electrophotography, for illumination systems including light sources used in electrophotos:graphic devices, specifically

177+, for exposure. 431, Combustion,

357+, for photoflash bulbs, per se, of the combustible type and combinations which include means for igniting such specific bulbs. That section also provides for a nominal light source, such as a "flashbulb", or a nominal light modifier or "reflector" if combined with specific mechanical igniting means, such as percussive means and which may include light source support means. See the reference to Class 361 above which provides for more general utility electrical ignition means that are not limited by light source, modifier or support details.

439, Electrical Connectors,

151, for a coupling part connector combined with means to allow repositioning of a mating part for engagement of different contacts on the mating part (e.g., a flash cube); and subclasses 620+ for an electrical connector combined with a named circuit component; and see the notes appended thereto.
