Retrofit LED lamp for fluorescent fixtures without ballast
First Claim
1. A light emitting diode (LED) lamp for mounting to a fluorescent light fixture having the ballast removed or bypassed including opposed electrical sockets, comprising:
- a tube having tube ends, said tube having opposed electrical contacts for positioning into the opposed electrical sockets, at least one LED positioned within said tube between said tube ends, a source of electrical power, electrical circuit means for providing electrical power from said source of electrical power to said at least one LED, means for electrically connecting said electrical circuit means from said opposed electrical contacts to the opposed electrical sockets, 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 sensing requirements for lighting around the illumination area of said at least one LED, and means for controlling the delivery of said electrical power from said source of electrical power to said at least one LED relating to said means for sensing requirements for lighting around the illumination area of said at least one LED.

Abstract
An energy saving device for an LED lamp mounted to an existing fixture for a fluorescent lamp where the ballast is removed or bypassed. The LEDs are positioned within a tube and electrical power is delivered from a power source to the LEDs. The LED lamp includes means for controlling the delivery of the electrical power from the power source to the LEDs, wherein the use of electrical power can be reduced or eliminated automatically during periods of non-use. Such means for controlling includes means for detecting the level of daylight in the illumination area of said least one LED, in particular a light level photosensor, and means for transmitting to the means for controlling relating to the detected level of daylight from the photosensor. The photosensor can be used in operative association with an on-off switch in power connection to the LEDs, a timer, or with a computer or logic gate array in operative association with a switch, timer, or dimmer that regulates the power to the LEDs. An occupancy sensor that detects motion or a person in the illumination area of the LEDs can be also be used in association with the photosensor and the computer, switch, timer, or dimmer, or in solo operation by itself. Two or more such LED lamps with a computer or logic gate array used with at least one of the lamps can be in network communication with at least one photosensor and/or at least one occupancy sensor to control the power to all the LEDs.
