Title: Cassette for holding a planar light source with a thermally isolated driver board

Abstract

A loadable cassette holds a planar light source, such as a flat OLED panel, along with a companion driver board in a manner that allows both the light source and driver board to be operatively and replaceably connected to a luminaire or lighting system. The cassette maintains an air gap between the light source and driver board so as to prevent heat produced by the driver board from damaging the light source.

Driver circuit for solid state light sources

Patent Palmer, Fred; Denvir, Kerry; Allen, Steven

A driver circuit for a light source including one or more solid state light sources, a luminaire including the same, and a method of so driving the solid state light sources are provided. The driver circuit includes a rectifier circuit that receives an alternating current (AC) input voltage and provides a rectified AC voltage. The driver circuit also includes a switching converter circuit coupled to the light source. The switching converter circuit provides a direct current (DC) output to the light source in response to the rectified AC voltage. The driver circuit also includes a mixing circuit, coupled to themore » « less

Solid state light source driver establishing buck or boost operation

Patent Palmer, Fred

A solid state light source driver circuit that operates in either a buck convertor or a boost convertor configuration is provided. The driver circuit includes a controller, a boost switch circuit and a buck switch circuit, each coupled to the controller, and a feedback circuit, coupled to the light source. The feedback circuit provides feedback to the controller, representing a DC output of the driver circuit.

Printed circuit board for integrated LED driver

Patent Song, Zhihua; Soer, Wouter; Bonne, Ron; ...

A multi-layer metal core printed circuit board (MCPCB) has mounted on it at least one or more heat-generating LEDs and one or more devices configured to provide current to the one or more LEDs. The one or more devices may include a device that carries a steep slope voltage waveform. Since there is typically a very thin dielectric between the patterned copper layer and the metal substrate, the steep slope voltage waveform may produce a current in the metal substrate due to AC coupling via parasitic capacitance. This AC-coupled current may produce electromagnetic interference (EMI). To reduce the EMI, amore » « less

Switched-capacitor isolated LED driver

Patent Sanders, Seth R.; Kline, Mitchell

A switched-capacitor voltage converter which is particularly well-suited for receiving a line voltage from which to drive current through a series of light emitting diodes (LEDs). Input voltage is rectified in a multi-level rectifier network having switched capacitors in an ascending-bank configuration for passing voltages in uniform steps between zero volts up to full received voltage V.sub.DC. A regulator section, operating on V.sub.DC, comprises switched-capacitor stages of H-bridge switching and flying capacitors. A current controlled oscillator drives the states of the switched-capacitor stages and changes its frequency to maintain a constant current to the load. Embodiments are described for isolatingmore » « less
