Thermal Protection For Lamp Ballasts

View page
US Patent:
6982528, Jan 3, 2006
Filed:
Nov 12, 2003
Appl. No.:
10/706677
Inventors:
David E. Cottongim - Sellersville PA, US
Jecko Arakkal - Emmaus PA, US
Venkatesh Chitta - Center Valley PA, US
Mark S. Taipale - Harleysville PA, US
Assignee:
Lutron Electronics Co., Inc. - Coopersburg PA
International Classification:
G05F 1/00
H01H 5/04
US Classification:
315309, 315307, 315291, 315118, 361106, 361103
Abstract:
The output current of a ballast is dynamically limited when an over-temperature condition is detected in the ballast according to one of (i) a step function or (ii) a combination of step and continuous functions, so as to reduce the temperature of the ballast while continuing to operate it.

US Patent:
7436131, Oct 14, 2008
Filed:
Aug 29, 2005

Jecko Arakkal - Emmaus PA, US
Venkatesh Chitta - Center Valley PA, US
Mark S. Taipale - Harleysville PA, US
Assignee:

International Classification:
G05F 1/00
US Classification:
315309, 315307, 315291, 315224

Apparatus And Method For Controlling The Filament Voltage In An Electronic Dimming Ballast

View page
US Patent:
7586268, Sep 8, 2009
Filed:
Jul 21, 2006
Appl. No.:
11/491202
Inventors:
Brent Gawrys - Whitehall PA, US
Jecko J. Arakkal - Emmaus PA, US
Mark S. Taipale - Harleysville PA, US
Dragan Veskovic - Allentown PA, US
Mark Charles Fischer - Siler City NC, US
Assignee:
Lutron Electronics Co., Inc. - Coopersburg PA
International Classification:
H05B 41/16
US Classification:
315274, 315224, 315307, 315312
Abstract:
An electronic dimming ballast comprises a filament turn-off circuit for controlling the magnitudes of filament voltages supplied to the filaments of a gas discharge lamp. Each of a plurality of filament windings is directly coupled to one of the filaments and is operable to supply a small AC filament voltage to the filaments. The plurality of filament windings and a control winding are loosely magnetically coupled to a resonant inductor of an output circuit of the ballast. A controllably conductive device is coupled across the control winding. When the controllably conductive device is conductive, the voltage across the control winding and the filament windings falls to zero volts. The controllably conductive device is driven with a pulse-width modulated (PWM) signal so as to control the magnitudes of the filament voltages. The filament voltages are provided to the filaments before striking the lamp, and when dimming the lamp near low end.

Electronic Dimming Ballast For Compact Fluorescent Lamps

View page
US Patent:
6642669, Nov 4, 2003
Filed:
Jun 1, 2002
Appl. No.:
10/160546
Inventors:
Russell L. MacAdam - Coopersburg PA
Andrew Ryan Offenbacher - Quakertown PA
Jecko J. Arakkal - Emmaus PA
Assignee:
Lutron Electronics Co., Inc. - Coopersburg PA
International Classification:
H05B 3702
US Classification:
315244, 315224, 315DIG 4
Abstract:
The operating frequency of a ballast is sufficiently far from resonance that, when a compact fluorescent lamp is dimmed to about one percent light output level, the ballast is operating with an open loop gain below a predetermined level, such as, for example, 15, and is operating with an output impedance greater than a predetermined level, such as, for example, the absolute value of the maximum negative incremental impedance of the lamp, and more preferably, greater than twice the absolute value of the maximum negative incremental impedance of the lamp. By changing the frequency to 85 kHz from 80 kHz, for example, the gain is maintained about the same whether the light output is at five percent or one percent, for example. This provides a stable control loop. In this manner, compact fluorescent lamps can be dimmed below about one percent light output, without dropping out and without observable flicker.
