US Patent:

6452339, Sep 17, 2002

Filed:

Dec 15, 1999

Appl. No.:

09/461983

Inventors:

Joseph F. Morrissey - Rockland MA
Jeff Walters - Marshfield MA

Assignee:

Acuity Brands, Inc. - Atlanta GA

International Classification:

H05B 3702

US Classification:

315149, 315119, 315159

Abstract:

A photocontroller diagnostic system including a photocontroller with a sensor for determining the presence of daylight, and a relay, responsive to the sensor, for de-energizing a lamp during periods of daylight. The diagnostic subsystem is responsive to the photocontroller, and includes a microprocessor programmed to verify the operability of the relay and/or the sensor and programmed to transmit a signal representative of the operability of the relay or the sensor.

Assignee:

Acuity Brands, Inc. - Atlanta GA

International Classification:

H01J 724
G05F 100

US Classification:

315119, 315308

Abstract:

A diagnostic and configuration identification system for an electrical device and a Photo-controller which automatically turns the electrical device on and off in response to ambient light levels. A detector senses the load drawn by the electrical device when it is on. A processor is responsive to the load drawn by the electrical device when it is on and programmed to detect a cycling fault condition based on the load drawn by the electrical device and to provide an indication of a cycling fault condition according several possible programming configurations. When no cycling or other fault condition is detected the processor determines the cycling fault condition indication configuration and then outputs a cycling signal indicative of the program configuration.

Appl. No.:

09/121382

Inventors:

JOSEPH F. MORRISSEY JR. - ROCKLAND MA, US
JEFFREY WALTERS - MARSHFIELD MA, US

International Classification:

G01J005/20

US Classification:

250/338400

Abstract:

A filtered photocontroller with a housing including a window portion; a circuit board within the housing including a light sensor behind the window portion of the housing; and a polymer filter which attenuates infrared radiation in front of the light sensor for improving the responsiveness of the photocontroller.

Appl. No.:

8/914661

Inventors:

Joseph F. Morrissey - Rockland MA
Jeff Walters - Marshfield MA
Lucinda Seigel - San Francisco CA

Assignee:

Dark to Light - Pembroke MA

International Classification:

H05B 3700

US Classification:

315119

Abstract:

A luminaire diagnostic system including a lamp and a photocontroller for automatically turning the lamp on during periods of darkness and off during periods of daylight wherein the photocontroller includes detector circuitry for detecting the load drawn by the lamp, a microprocessor, responsive to detected load and programmed to predict a condition of the lamp such as a cycling event and/or lamp out condition based on the load drawn by the lamp, and an indicator such as a visual alarm for indicating the occurrence of the condition detected and/or a transmitter for transmitting the detected condition to a remote location. Also, upon cycle detection, the lamp may be turned off to prevent damage to fixture components.
