Patent number: 9797587Abstract: An electrical interface module (EIM) is provided between an LED illumination device and a light fixture. The EIM includes an arrangement of contacts that are adapted to be coupled to an LED illumination device and a second arrangement of contacts that are adapted to be coupled to the light fixture and may include a power converter. Additionally, an LED selection module may be included to selectively turn on or off LEDs. A communication port may be included to transmit information associated with the LED illumination device, such as identification, indication of lifetime, flux, etc. The lifetime of the LED illumination device may be measured and communicated, e.g., by an RF signal, IR signal, wired signal or by controlling the light output of the LED illumination device. An optic that is replaceably mounted to the LED illumination device may include, e.g., a flux sensor that is connected to the electrical interface.Type: GrantFiled: June 2, 2016Date of Patent: October 24, 2017Assignee: Xicato, Inc.Inventors: Gerard Harbers, Gregory W.

Patent number: 9631782Abstract: An illumination device includes a plurality of Light Emitting Diodes (LEDs) in a rectangular light mixing cavity mounted above the LEDs and configured to mix and color convert light emitted from the LEDs. The long sidewall surfaces of the rectangular light mixing cavity are coated with a first type of wavelength converting material while the short sidewall surfaces reflect incident light without color conversion. The output window that is above and separated from the LEDs is coated with a second type of wavelength converting material. The light mixing cavity may include a replaceable, reflective insert that includes a non-metallic, diffuse reflective layer backed by a second reflective layer. Additionally, the LEDs may be mounted on raised pads on a mounting board. The light mixing cavity may include a bottom reflector with holes wherein the raised pads elevate the LEDs above the top surface of the bottom reflector through the holes.Type: GrantFiled: January 27, 2011Date of Patent: April 25, 2017Assignee: Xicato, Inc.Inventors: Gerard Harbers, Kelly C. McGroddy, Christopher R. Reed

Patent number: 9557017Abstract: A light emitting diode module is produced using at least one LED and at least two selectable components that form a light mixing chamber. First and second selectable components have first and second types of wavelength converting materials with different wavelength converting characteristics. The first and second wavelength converting characteristics alter the spectral power distribution of the light produced by the LED to produce light with a color point that is a predetermined tolerance from a predetermined color point. Moreover, a set of LED modules may be produced such that each LED module has the same color point within a predetermined tolerance. The LED module may be produced by pre-measuring the wavelength converting characteristics of the different components selecting components with wavelength converting characteristics that convert the spectral power distribution of the LED to a color point that is a predetermined tolerance from a predetermined color point.Type: GrantFiled: February 1, 2016Date of Patent: January 31, 2017Assignee: Xicato, Inc.Inventors: Gerard Harbers, Peter K.

Patent number: 9010977Abstract: A mounting collar on a light fixture provides a compressive force between the illumination module and a light fixture. For example, a mounting collar that is fixed to the light fixture may engage with an illumination module to deform elastic mounting members on the illumination module to generate the compressive force. The mounting collar may include tapered features on first and second members that are moveable with respect to each other and that when engaged generate the compressive force. The mounting collar may include elastic mounting members on first and second members that move with respect to each other, wherein the movement deforms the elastic mounting members to generate the compressive force. The mounting collar may include an elastic member, wherein movement movement of the mounting collar relative to a light fixture deforms the elastic member to generate the compressive force.Type: GrantFiled: September 26, 2012Date of Patent: April 21, 2015Assignee: Xicato, Inc.Inventors: Gerard Harbers, Gregory W.
