Dimmable Multichannel Driver For Solid State Light Sources

View page
US Patent:
20130293151, Nov 7, 2013
Filed:
Mar 13, 2013
Appl. No.:
13/799885
Inventors:
Voravit Puvanakijjakorn - Beverly MA, US
Masatoshi Honji - Westborough MA, US
Anne Janet Milliez - Brighton MA, US
Assignee:
OSRAM SYLVANIA Inc. - Davners MA
International Classification:
H05B 33/08
US Classification:
315297
Abstract:
Systems and methods for driving solid state light sources are provided. A first drive circuit is configured to generate a drive current to cause a first solid state light source load and a second solid state light source load to illuminate. A feedback and control circuit is configured to receive feedback from the first solid state light source load and to control the drive current through the first solid state light source load based on the feedback. A second drive circuit is configured to control the drive current through the second solid state light source load. A master controller is configured to provide a first input to the feedback and control circuit to control the drive current through the first solid state light source load and a second input to the second drive circuit to control the drive current through the second solid state light source load.

Driver Circuit For Reduced Form Factor Solid State Light Source Lamp

US Patent:
20120286663, Nov 15, 2012
Filed:
Jan 20, 2012
Appl. No.:
13/354389
Inventors:
Voravit Puvanakijjakorn - Beverly MA, US
Sean Lei - Malden MA, US
Arunava Dutta - Winchester MA, US
Assignee:
OSRAM SYLVANIA INC. - Danvers MA
International Classification:
H05B 37/02
US Classification:
315 85
Abstract:
A solid state light source driver circuit, system and method are provided. The driver circuit includes a rectifier circuit, an energy storage element coupled thereto, a current bleeder circuit coupled thereto, and a switch. The rectifier circuit receives AC input and provides unregulated DC voltage. The switch closes to couple some of the unregulated DC voltage to the energy storage element, and opens to transfer energy to drive the light source. A power factor controller circuit provides an output signal to control the switch. The current bleeder circuit provides supply voltage to the power factor controller circuit within a range and maintains a current flow associated with the AC input that exceeds a predetermined threshold. A constant off-time controller circuit provides a switching frequency control signal to the power factor controller circuit. An EMI filter reduces generated EMI noise.

International Classification:
A61L 9/00
A61L 9/20
A61L 9/22
Abstract:
Apparatus, methods and instructions for disinfecting air. The apparatus may include, and the methods may involve, a fixture. The fixture may include a germicidal light source. The fixture may include a fan. The fan may circulate air through a volume into which the germicidal light source propagates germicidal light. The light source may be configured to emit, upward from a horizontal plane, a beam that, absent reflection off an environmental object, does not cross the horizontal plane. The apparatus may include a shield that prevents light from the light source from crossing the horizontal plane. The sensor may face upward from the horizontal plane. The sensor may face downward from the horizontal plane.

H05B 47/17
H05B 47/175
F21V 23/00
Abstract:
Apparatus and methods for providing LED lighting on light tape and light sheet. A controller may provide lighting control data to one or more ICs on a segment of tape or sheet. The lighting control data may include a data packet. The data packet may include an address. The address may correspond to one or more of the ICs. The address may correspond to one or more LEDs on the segment. The address may correspond to one or more LEDs on a light tape. The address may correspond to one or more LEDs on a light sheet. The LEDs corresponding to the address may be controlled by a current regulator or regulators on a single IC. The LEDs corresponding to the address may be controlled by current regulators on different ICs.

Abstract:
LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are spotlights while other fixture are intended for in ground use. The light fixtures in at least some embodiments include power control features. In spotlight embodiments beam angle and power or light output can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. In ground embodiments support tilt angle setting which allow a user to set the light fixture to one or more tilt angles. Beam angle can also be changed in some embodiments as well as power control. Beam angle, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.
