In operation, broad spectrum light from the lamp exits the lamp housing by passing through the light-port. The first lens then collimates the broad spectrum light that exits the lamp housing through the light-port. The infrared absorbing filter then passes a first portion of the collimated broad spectrum light to the optical filter and absorbs infrared light of the broad spectrum light. The optical filter then passes a second portion of the collimated broad spectrum light to the second lens. The second lens then disperses the second portion of the collimated light to provide uniform irradiation of a cell culture plate. A method of using the lighting system for studying a photosensitizer is also disclosed.Type: ApplicationFiled: November 29, 2012Publication date: December 5, 2013Applicant: PINNACLE BIOLOGICS, INC.Inventor: Michael S.

Publication number: 20130308318Abstract: The improvements include an illuminator for a gun comprising a manually manipulated and storable external IR filler with a plurality of radially directed circumferential tabs integrally extending from the frame to allow a manual torque to be applied to the frame to manually screw it into and out of the bezel in the field. A high g-force diaphragm shock mount for the lamp includes a receptacle which positions the longitudinal axis of the lamp on the optical axis of the reflector. The field serviceable lamp assembly is an integrated or modular and sealed unit. A field serviceable electronics module is accessed by removing the rear bezel. The illuminator handle includes a double locked latch lever. A T-Slot to Picatinny adapter allows a SureFire T-rail fitting of the handle to fit a conventional Picatinny rail.Type: ApplicationFiled: July 30, 2013Publication date: November 21, 2013Applicant: SureFire LLCInventors: Gregory Z.

Patent number: 8550660Abstract: An apparatus creating a flickering flame effect. The apparatus includes a housing with an interior space with first and second stages. A drive mechanism generates a time varying electromagnetic field extending into the first stage. A first pendulum member is pivotally mounted in the interior space of the first stage and includes first and second magnets on first and second ends, with the first end proximate to the drive mechanism such that the first magnet interacts with the varying electromagnetic field to cause movement of the pendulum member. The apparatus includes a second pendulum member pivotally mounted in the second stage with a magnet on a first end proximate to the second end of the first pendulum member. A flame silhouette element extends from the second pendulum member, and a light source transmits light onto the flame silhouette, which is moving due to the magnetic coupling of the pendulum members.Type: GrantFiled: February 4, 2013Date of Patent: October 8, 2013Assignee: Disney Enterprises, Inc.Inventors: Douglas M. Patton, Gary W. Schnuckle

Publication number: 20130250211Abstract: There is provided a color-regulating device for illumination. The color-regulating device includes a light-valving structure for adjusting a flux ratio of outgoing light through the light-valving structure to incident light entering the light-valving structure, and a color-adjusting structure having a wavelength-band converting element for changing incident light with a wavelength band into outgoing light with a different wavelength band through the element. Wherein, the light-valving structure and the color-adjusting structure do not overlap on the traveling path of the light emitted from the light source. Mixing the outgoing light of the light source passing through the light-valving structure with the outgoing light of the light source passing through and at least a portion thereof converted by the color-adjusting structure with a different wavelength band yields a color-adjusted light of different color temperature from that of the light source.Type: ApplicationFiled: May 24, 2013Publication date: September 26, 2013Applicant: Planck Co., Ltd.Inventors: Chin-Yu CHAO, Chiu-Chang HUANG, Chieh-Hsiung KUAN, Vin-Cent SU

Publication number: 20130208480Abstract: An illumination device comprises a housing (5) with a plurality of compartments (3), each compartment comprising a respective light emission window (15), a light source (11), and a stack of crossed prismatic sheets (10). Light issued by the light source during operation is made to propagate through the prismatic sheets and subsequently through the light emission window. The orientation of the stack of sheets is different for each compartment, thus causing each compartment to issue a different beam of light. The light source of each compartment is separately switchable, thus enabling easy setting of the type of beam issued form the illumination device. Optionally a diffuser (17, 23) is provided at one side or at both sides of the stack of prismatic sheets to enhance the homogeneity of the issued light.Type: ApplicationFiled: October 13, 2011Publication date: August 15, 2013Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventor: Erik Boonekamp
