Patent number: 8469547Abstract: Systems and methods permit use of efficient solid state emitters for broad spectrum continuous spectrum lighting defined by illumination data. The illumination data, which can be sold as a commercial product, can be recorded or authored and include spectral, temporal, and spatial information. Intensities of individual emitters such as LEDs can be controlled through a combination of pulse width modulation (PWM) and amplitude modulation (AM) of drive currents. The combination of PWM and AM permits fine tuning of the spectrum of emissions and creation of free space optical data channels.Type: GrantFiled: May 11, 2011Date of Patent: June 25, 2013Assignee: Telelumen, LLCInventor: Steven Paolini

Publication number: 20120238041Abstract: A light emitting device is produced by depositing a layer of wavelength converting material over the light emitting device, testing the device to determine the wavelength spectrum produced and correcting the wavelength converting member to produce the desired wavelength spectrum. The wavelength converting member may be corrected by reducing or increasing the amount of wavelength converting material. In one embodiment, the amount of wavelength converting material in the wavelength converting member is reduced, e.g., through laser ablation or etching, to produce the desired wavelength spectrum.Type: ApplicationFiled: June 4, 2012Publication date: September 20, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: STEVEN PAOLINI, MICHAEL D.

Publication number: 20120235600Abstract: A method of utilizing a light replication luminaire to match the spectral characteristics of light that is output from the luminaire to the spectral characteristics of a target light spectrum is provided. In one example, the method permits the user to assign a weight to one or more characteristics of the target light spectrum to be replicated. A best approximation of the target light spectrum is then determined, taking into account the weight assigned to each characteristic. In another example, the target light spectrum is provided to the luminaire by the user through the specification of various characteristics of the target light spectrum.Type: ApplicationFiled: March 15, 2011Publication date: September 20, 2012Applicant: Telelumen LLCInventors: Dmitri Simonian, Steven Paolini, Richard Jui-chi Koo

Publication number: 20110137757Abstract: Embodiments of the present invention relate to systems and methods for creating, distributing and playing illumination data files. The illumination data files, created using luminaire development systems are uploaded to a luminaire management system, where they are further processed and packaged for sale or license within a luminaire marketplace. Consumers and enterprises using luminaires may establish accounts with the luminaire management system and marketplace to access illumination data files for playback on individual or multiple luminaires. Consumers and enterprises may also create play lists and uniquely configure the luminaires to display various lighting effects based on user preferences, environmental factors or energy efficient settings.Type: ApplicationFiled: February 19, 2011Publication date: June 9, 2011Inventors: Steven Paolini, John Giddings

Patent number: 6791636Abstract: In one embodiment, a color, transmissive LCD uses red, green, and blue LEDs as the light source. The red LED is optically coupled to a first edge of a rectangular light guide; the green LED is optically coupled to a second edge of the light guide; and the blue LED is optically coupled to a third edge of the light guide. Three sets of deformities in the light guide selectively direct the R, G, and B light out of the front surface of the light guide. The R, G, and B LEDs are constantly on and there is no color filtering. In another embodiment, a blue light LED is optically coupled to one or more edges of a light guide, and phosphor strips are placed on a surface of the light guide coinciding with the red and green pixel columns. Deformities below the red and green phosphor strips and below the blue pixel areas direct blue light to the backs of the phosphor strips and to the blue pixel areas. If an ultraviolet light LED is used, phosphor strips for the blue pixel areas would also be used.Type: GrantFiled: May 10, 2001Date of Patent: September 14, 2004Assignee: Lumilecs Lighting U.S., LLCInventors: Steven PĂ olini, Gerard Harbers, Wayne L.

Patent number: 6768525Abstract: A color, transmissive LCD is described herein which uses red, green, and blue LEDs as the light source. The R, G, and B LEDs are coupled to separate light guides, one light guide for each color. These light guides may take the form of three overlying plastic or glass sheets. In another embodiment, thin fiber optic cables arranged parallel to each other on a supporting surface are used as the light guides, and each fiber optic cable is optically coupled to only one R, G, or B LED in a repeating pattern. The light guides contain deformities to emit light coinciding with the positions of the red, green, and blue pixels. The R, G, and B LEDs are constantly on, and there is no color filtering.Type: GrantFiled: December 1, 2000Date of Patent: July 27, 2004Assignee: Lumileds Lighting U.S. LLCInventors: Steven Paolini, Gerard Harbers, Wayne L.

Patent number: 4998119Abstract: A light emitting diode printhead has a row of LED dice, with each die having one or more rows of LEDs. The LED die substrate forms a common cathode for the LEDs on that die. There is a time multiplex driver for a plurality of dice comprising a plurality of current sources. Each current source comprises a current driver FET and a data FET in series. Each data FET is connected in parallel to the anodes of corresponding LEDs on all of the dice. Switches selectively connect the substrate of each die to ground. A latching shift register is used for applying data for a selected die to the data FETs. The register is divided into the same number of blocks as the number of dice, and each block has the same number of bits as the LEDs on a die. At the same time a block of data for a selected die is connected to the data FETs, the substrate of the selected die is connected to ground, thereby enabling only the light emitting diodes on the selected die.Type: GrantFiled: December 15, 1989Date of Patent: March 5, 1991Inventors: William D. Collins, Steven Paolini, John J. Uebbing
