Power controls for tube mounted LEDs with ballast
First Claim
1. A light emitting diode (LED) lamp for mounting to an existing fixture for a fluorescent lamp having a ballast assembly including ballast opposed electrical contacts, comprising:
- a tube having tube ends,at least one LED positioned within said tube between said tube ends,electrical circuit means for providing electrical power from the ballast assembly to said at least one LED,means for electrically connecting said electrical circuit means with the ballast opposed electrical contacts,said electrical circuit means including an LED electrical circuit including at least one electrical string positioned within said tube and generally extending between said tube ends, said at least one LED being in electrical connection with said at least one electrical string,said at least one LED being positioned to emit light through said tube,means for supporting and holding said at least one LED and said LED electrical circuit,means for suppressing ballast voltage being delivered from the ballast assembly, said means for suppressing ballast voltage being in electrical connection with said electrical circuit means, andmeans for controlling the delivery of said electrical power from said ballast assembly to said at least one LED.

Abstract
A power saving device for a light emitting diode (LED) lamp mounted to an existing fixture for a fluorescent lamp having a ballast assembly and LEDs positioned within a tube and electrical power delivered from the ballast assembly to the LEDs. The LED lamp includes a device for controlling the delivery of the electrical power from the ballast assembly to the LEDs wherein the use of electrical power can be reduced or eliminated automatically during periods of non-use. Such device for controlling can include an on-off switch mounted in the tube or can also include a current driver dimmer mounted in the tube that regulates the amount of power delivered to the LEDs. A computer or logic arrays control the dimmer or power switch. A sensor such as an occupancy motion detection sensor mounted external to the tube or within the tube can send signals to the computer or logic array to trigger a switch or control a dimmer. Two or more such LED lamps with one or more computers or logic arrays in network communication with sensors can be controlled, so as to reduce flickering between lamps when illumination areas are being alternately occupied. Preset or manually set timers can control switches or be used in combination with the computer, logic array, and dimmer.
