Patent number: 8314566Abstract: In one embodiment, an LED lamp has a generally bulb shape. The LEDs are low power types and are encapsulated in thin, narrow, flexible strips. The LEDs are connected in series in the strips to drop a desired voltage. The strips are affixed to the outer surface of a bulb form to provide structure to the lamp. The strips are connected in parallel to a power supply, which may be housed in the lamp. Since many low power LEDs are used and are spread out over a large surface area, there is no need for a large metal heat sink. Further, the light emission is similar to that of an incandescent bulb. In other embodiment, there is no bulb form and the strips are bendable to have a variety of shapes. In another embodiment, a light sheet is bent to provide 360 degrees of light emission. Many other embodiments are described.Type: GrantFiled: February 22, 2011Date of Patent: November 20, 2012Assignee: Quarkstar LLCInventors: Robert Steele, Louis Lerman, Allan Brent York, Wilson Dau, Jacqueline Teng, George Lerman

Publication number: 20120268931Abstract: A solid state light sheet and method of fabricating the sheet are disclosed. In one embodiment, bare LED chips have top and bottom electrodes, where the bottom electrode is a large reflective electrode. The bottom electrodes of an array of LEDs (e.g., 500 LEDs) are bonded to an array of electrodes formed on a flexible bottom substrate. Conductive traces are formed on the bottom substrate connected to the electrodes. A transparent top substrate having conductors is then laminated over the bottom substrate. Various ways to connect the LEDs in series are described along with many embodiments. The light sheets may be formed to emit light from opposite surfaces of the light sheet, enabling it to be used in a hanging fixture to illuminate the ceiling as well as the floor. The light sheet provides a practical substitute for a standard 2×4 foot fluorescent ceiling fixture.Type: ApplicationFiled: June 29, 2012Publication date: October 25, 2012Applicant: QUARKSTAR LLCInventors: Louis Lerman, Allan Brent York, Michael David Henry, Robert Steele, Brian D.

Publication number: 20120250319Abstract: A solid state, bidirectional light sheet and method of fabricating the sheet are disclosed. In one embodiment, bare LED chips have top and bottom electrodes, where the bottom electrode is a large reflective electrode. An array of LEDs (e.g., 500 LEDs) is sandwiched between at least two transparent substrates having conductors bonded to the electrodes without wires. Various ways to connect the LEDs in series are described along with various embodiments. The light sheets are formed to emit light from opposite surfaces of the light sheet to create a bidirectional light sheet. The light sheet may be suspended from a ceiling to be perpendicular to the ceiling, or the angles of the light sheet may be adjusted. The suspended light sheet may form a cylinder for uniform illumination of the floor and ceiling. Lenses may be formed in the light sheet to emit light at any peak intensity angle to achieve any light emission pattern.Type: ApplicationFiled: May 31, 2012Publication date: October 4, 2012Applicant: QUARKSTAR LLCInventors: Wilson Dau, Louis Lerman, Allan Brent York

Publication number: 20120194095Abstract: A multi-dimensional controller (150) controls the multiple parameters of a lighting system (250). A track-ball (100) that provides three axes of rotation (101-103), for example, is used to control each of three lighting parameters, such as chrominance, luminance, and saturation. In like manner, intensity, direction, and diffusion control may be controlled by a device with three degrees of freedom/control. Force-feedback (120) is optionally provided to indicate divergence from established presets (220) or recommended operating conditions. Switches (130) and other control elements are also provided to store or recall preset parameters (220), override scheduled lighting settings, and so on.Type: ApplicationFiled: September 28, 2011Publication date: August 2, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Ian Ashdown, Damien Loveland, Allan Brent York, Aloysius Cornelis Arnoldus Maria Ketelaars, A.J.W.A.

Publication number: 20110220870Abstract: Light emitting devices comprise excitation sources arranged to excite quantum dots which fluoresce to emit light. In an embodiment, a device is manufactured by a process which involves applying an acoustic field is applied to a fluid containing quantum dots, to cause the quantum dots to accumulate at locations which are adjacent to excitation sources, and then initiating a phase transition of the fluid to trap the quantum dots in the locations adjacent to the excitation sources. The quantum dots are illuminated during the process and the resulting fluorescence is optically monitored to provide indicators of quantum dot distribution in the fluid. These indicators are used as feedback for controlling aspects of the process, such as initiating the phase transition.Type: ApplicationFiled: March 10, 2011Publication date: September 15, 2011Applicant: LIGHT-BASED TECHNOLOGIES INCORPORATEDInventors: Yohann Sulaiman, Richard MacKellar, Allan Brent York
