Led Lighting Unit Including Elongated Heat Sink And Elongated Lens

View page
US Patent:
7815338, Oct 19, 2010
Filed:
Mar 2, 2008
Appl. No.:
12/040901
Inventors:
Dennis Siemiet - Rochester Hills MI, US
David L Simon - Grosse Pointe Farms MI, US
Huaiyao Yuan - Buffalo Grove IL, US
Assignee:
Altair Engineering, Inc. - Troy MI
International Classification:
F21V 29/00
US Classification:
362218, 362294, 362373, 36224902
Abstract:
A LED lighting unit including an elongated heat sink having two spaced apart longitudinal grooves, the grooves facing tangentially or at an angle greater than an angle between a tangent of the lighting unit at the groove and a radius of the lighting unit at the groove. At least one LED is mounted to the heat sink between the grooves, and the at least one LED is enclosed by a lens having bulged longitudinal edges by sliding the bulged longitudinal edges into the grooves.

Light Distribution Using A Light Emitting Diode Assembly

View page
US Patent:
7926975, Apr 19, 2011
Filed:
Mar 16, 2010
Appl. No.:
12/724645
Inventors:
Dennis Siemiet - Rochester Hills MI, US
John Ivey - Farmington Hills MI, US
Francis Palazzolo - Sterling Heights MI, US
Assignee:
Altair Engineering, Inc. - Troy MI
International Classification:
F21V 1/00
F21V 7/04
US Classification:
362240, 362246, 362555
Abstract:
A fluorescent light tube retrofit with light emitting diodes (LEDs) that evenly distribute light to avoid bright spots is disclosed. One LED lighting unit includes a tubular housing and a plurality of LED assemblies mounted about a circumference of the tubular housing. LEDs face inward from a mounting surface that is angled offset of the tube. Alternatively, at least one LED can be oriented to emit light parallel to a tangent of the housing into a light pipe that curves inside at least a portion of the tubular housing.

Electric Shock Resistant L.e.d. Based Light

View page
US Patent:
8360599, Jan 29, 2013
Filed:
May 23, 2008
Appl. No.:
12/126579
Inventors:
John Ivey - Farmington Hills MI, US
Dennis Siemiet - Rochester Hills MI, US
Assignee:
ilumisys, Inc. - Troy MI
International Classification:
F21V 7/20
F21V 29/00
F21S 4/00
US Classification:
362218, 362223, 362225
Abstract:
A LED-based replacement light for a fluorescent socket is constructed such that an entirety of a radially outer portion of a tubular housing at least partially defined by a high-dielectric light transmitting portion is formed of a high-dielectric material. Forming a radially outer portion of the tubular housing of a high-dielectric material prevents a person handling the light from being shocked as a result of capacitive coupling occurring when the LED-based replacement light is installed one end at a time. A circuit board is in thermally conductive relation with the tubular housing, allowing for conduction of heat generated by the LEDs from a side of circuit board opposite the LEDs to the tubular housing for dissipation to the ambient environment.

Light Distribution Using A Light Emitting Diode Assembly

US Patent:
20090161359, Jun 25, 2009
Filed:
Dec 21, 2007
Appl. No.:
11/962995
Inventors:
Dennis Siemiet - Rochester Hills MI, US
John Ivey - Farmington Hills MI, US
Francis Palazzolo - Sterling Heights MI, US
Assignee:
ALTAIR ENGINEERING, INC. - Troy MI
International Classification:
F21V 1/00
F21V 21/00
F21S 4/00
US Classification:
362235, 36224902
Abstract:
A fluorescent light tube retrofit with light emitting diodes (LEDs) that evenly distribute light to avoid bright spots is disclosed. One tube in the form of a conventional fluorescent tube includes two LEDs mounted to the tube on opposite sides of a single circumference of the tube. The LEDs can face the center of the tube, or the LEDs can be offset facing relative to the center of the tube. A reflecting surface can be disposed inside the tube to reflect light evenly toward an arc of the tube. Alternatively, at least one LED can be oriented to direct light into a light pipe that curves around the interior of the tube.

Led Lamp Failure Alerting System

View page
US Patent:
20100052542, Mar 4, 2010
Filed:
Sep 2, 2008
Appl. No.:
12/202662
Inventors:
Dennis Siemiet - Rochester Hills MI, US
John Ivey - Farmington Hills MI, US
Assignee:
Altair Engineering, Inc. - Troy MI
International Classification:
H01J 7/42
G01J 1/32
G01K 13/00
US Classification:
315129, 250205, 374142, 374E13001
Abstract:
Disclosed herein are embodiments of failure alerting systems for LED lamps and LED lamps having the same. An illustrative failure alerting system comprises a photodetector configured to detect an actual light output from the at least one LED, a regulator configured to receive a signal from the photodetector when the actual light output is below a target light output and to increase a current to the at least one LED to maintain the target light output, and a low light output indicator configured to receive a signal from the photodetector when the actual light output remains below the target light output and to produce a low light output signal. A thermal sensor can also be included and configured to sense an operating temperature of the LED and to control the regulator to increase the current and the target light output to ensure the operating temperature does not exceed the target temperature.

Electric Shock Resistant L.e.d. Based Light

US Patent:
20130128574, May 23, 2013
Filed:
Jan 16, 2013

13/742678
Inventors:
Dennis Siemiet - Rochester Hills MI, US
Assignee:
ILUMISYS, INC. - Troy MI
International Classification:
F21V 29/00
F21V 23/06
US Classification:
362235, 36224902
Abstract:
An LED-based light comprises: a tubular housing formed of a high-dielectric material and defined at least in part by a light transmitting portion; an elongate circuit board disposed within the housing; at least one LED mounted on the circuit board; an elongate heat sink disposed within the housing, the heat sink having an interior circuit board mounting surface opposing a radially outer surface, the circuit board mounted in thermally conductive relation to the circuit board mounting surface, substantially all of the radially outer surface of the heat sink in thermally conductive relation with the tubular housing for electrically insulated thermal transmission of heat generated by the LED from the circuit board to an ambient environment surrounding the LED-based light; and a pair of end caps disposed on opposing ends of the housing with connectors configured to physically connect the LED-based light to a conventional fluorescent light fixture.
