Publication number: 20100189429Abstract: A white light LED flash for a digital camera is described that uses a blue light LED die in conjunction with red and green phosphor or quantum dot material over the LED die. The phosphor or quantum dot characteristics are selected so that the white light substantially matches an ambient light setting in the camera, such as the incandescent ambient light setting. Therefore, when a flash picture is taken under incandescent ambient light, and the flash emits the same type of light as the incandescent light, the flash will effectively brighten the incandescent light. The camera's color compensation algorithm associated with incandescent light illumination is then applied to the photograph and works optimally since the image is only illuminated by incandescent light. This concept is expanded to LED flashes that emulate other types of ambient light having associated color compensation algorithms programmed into the camera.Type: ApplicationFiled: January 26, 2009Publication date: July 29, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventor: Mark BUTTERWORTH

Patent number: 4515558Abstract: A photoflash device which includes a plastic substrate, lamp-firing circuitry located on a first surface of the substrate, a disconnect switch also secured to the first surface of the substrate and electrically joined to the lamp-firing circuitry, at least one electrically activated photoflash lamp located above the switch for activating said switch upon ignition thereof, and a solid, light-transmitting polymer located about and encapsulating the glass envelope of the lamp. A thin, light-transmitting polyester member is located over the switch to protect the switch during formation of the device. The polyester member serves to prevent contact between the resin which forms the polymer and switch during thisformation, thus assuring close placement of the lamp's envelope and switch, said placement thereby assuring proper activation (e.g., severance) of the switch.Type: GrantFiled: January 6, 1982Date of Patent: May 7, 1985Assignee: GTE Products CorporationInventors: Harold H. Hall, Jr., Andre C. Bouchard

Patent number: 4498883Abstract: A method of forming a protective coating on a glass envelope of a photoflash lamp. The method comprises the steps of orienting the lamp within a mold member such that the external surfaces of the lamp's glass envelope do not contact the internal surfaces of the mold, depositing a quantity of powdered thermoplastic or thermosetting resin within the mold such that the resin surrounds the entirety of the glass envelope's external surfaces, simultaneously applying pressure and heat to the powdered material to cause it to liquify, and thereafter cooling the liquified material to form a light-transmitting, solid polymer member having the glass envelope located therein. Pressures within the range of about 500 to 8000 pounds per square inch were possible without fracturing the glass envelopes or adversely effecting the components therein. The finished product is ideally suited as one component of a multilamp photoflash device for use with many of today's cameras.Type: GrantFiled: July 18, 1983Date of Patent: February 12, 1985Assignee: GTE Products CorporationInventors: Andre C. Bouchard, Harold H. Hall, Jr.

Patent number: 4493639Abstract: A modified carbon ink for a flash lamp array circuit containing a particulated electrically conductive material such as graphite or metal flakes, metal-coated glass spheres and the like. The increased electrical conductivity obtained in this manner improved flashability and electrostatic flash out protection for the associated flash lamps.Type: GrantFiled: January 13, 1984Date of Patent: January 15, 1985Assignee: General Electric CompanyInventor: Mary E. Suster

Patent number: 4458298Abstract: A miniaturized multilamp photoflash includes a reflector member disposed within a plastic cover and having a plurality of cavities each containing a flashlamp and a pair of spaced leg members formed for engagement within a camera. A planar support platform is affixed to the reflector member and has a printed circuit on a surface adjacent the reflector member and a tab portion wider than the spaced leg members whereby insertion of the tab portion into a receiving socket is controlled by the width of the tab portion.Type: GrantFiled: November 3, 1982Date of Patent: July 3, 1984Assignee: GTE Products CorporationInventor: Donald W. Hartman
