Patent number: 9416925Abstract: An LED-based luminaire is configured to direct light from an LED source downwardly. However, a portion of the luminaire intentionally reflects part of the light upwardly toward a ceiling of a structure. A control circuit of an LED-based luminaire enables the luminaire to be dimmed by an off-the-shelf dimmer. The control circuit also determines when a temperature of the LED-based luminaire exceeds a desired temperature range, and employs a feedback circuit to reduce power delivery to the LEDs until the temperature is again within the desired temperature range.Type: GrantFiled: November 18, 2013Date of Patent: August 16, 2016Assignee: Permlight Products, Inc.Inventors: Kamran Sarmadi, Tom Brooks

Publication number: 20150082626Abstract: A modular light emitting diode (LED) mounting configuration is provided including a light source module having a plurality of pre-packaged LEDs arranged in a serial array. The module includes a heat conductive body portion adapted to conduct heat generated by the LEDs to an adjacent heat sink. As a result, the LEDs are able to be operated with a higher current than normally allowed. Thus, brightness and performance of the LEDs is increased without decreasing the life expectancy of the LEDs. The LED modules can be used in a variety of illumination applications employing one or more modules.Type: ApplicationFiled: April 22, 2014Publication date: March 26, 2015Applicant: Permlight Products, Inc.Inventors: John Popovich, Gregory W.

Patent number: 8926145Abstract: An LED-based luminaire employs an LED module mounted to a housing. The LED module is advantageously configured to transmit heat generated by the LEDs across and/or through the module and to the housing for dispersal to the environment. LED modules can be configured with conductive or non-conductive cores, and may be configured to evacuate heat from one or both faces of the LED module. Further, multiple heat paths can be defined from components on an LED module to the housing and to the environment.Type: GrantFiled: February 25, 2013Date of Patent: January 6, 2015Assignee: Permlight Products, Inc.Inventors: Fernando Lynch, James Steedly, Michael Bremser, Kamran Kohan, Johnny Kean

Publication number: 20140267461Abstract: An LED-based light engine has a circuit board upon which at least one LED circuit is mounted. A power driver is also mounted on the circuit board. The power driver accepts an AC input power and outputs a DC output power that powers the LED circuit. The circuit board is divided into an LED zone and a driver zone, which are thermally insulated relative to one another so that heat does not flow between the LED and driver zones. Slots are formed through the circuit board between the LED zone and driver zone to further block heat flow between the LED and driver zones.Type: ApplicationFiled: March 17, 2014Publication date: September 18, 2014Applicant: Permlight Products, Inc.Inventors: Kamran Sarmadi, Ismael Lopez
