Appl. No.:

12/709384

Inventors:

Steven W. Carlin - Lake Forest CA, US
Bob Chen - Diamond Bar CA, US
Fred Chen - Hacienda Heights CA, US

Assignee:

Pacific Dynamic - Newport Beach CA

International Classification:

H05B 37/02
H01J 13/32

US Classification:

315113, 315294, 36221713

Abstract:

According to various embodiments of the invention, an LED lighting system is providing having a replaceable driver module. In some embodiments, the replaceable driver module comprises a component that is physically attachable to an LED illumination module, whereby the attached components have a combined physical profile dimensioned for installation in a pre-existing light fixture. In further embodiments, the combined system's dimensions allow it to be installed in pre-existing fluorescent fixtures without requiring rewiring of the fixtures. In some embodiments, the LED driver module may be configured to condition power received from a fluorescent light ballast to drive the LEDs such that a pre-existing fluorescent ballast does not need to be removed. In other embodiments, the LED driver may be configured to condition main power such that a pre-existing fluorescent ballast may be removed.
