US 2008/0157698 A1 · LED Lighting Unit

Abstract

A lighting unit having a light generating section and a base section is disclosed. The base and light generating sections are reversibly connected by a series of mating connectors. The light generating section includes a plurality of groups of LEDs and a mixing structure. The base section includes an adapter that connects the lighting unit to an AC power receptacle designed to receive an incandescent lamp or a fluorescent lamp. The base section also includes a controller that powers the LEDs. The lighting unit also includes a sensor that periodically measures a parameter related to the intensity of light generated by each group of LEDs during the normal operation of the lighting unit. The controller uses this sensor to control the LEDs. The lighting section can also include a housing that has the shape of a conventional incandescent or fluorescent light fixture or light bulb.

Dependent claims

A lighting unit comprising:

a light generating section comprising:
one or more groups of LEDs, each group emitting light of a different spectrum than said other groups;
and
a plurality of light generating section connectors that provide power to said LEDs, each group of LEDs generating light at an intensity determined by a corresponding control signal received on said light generating section connectors;
and
a base section comprising:
a controller that generates and couples said control signals to said light generating section connectors;
and
a plurality of base section connectors that are connected to said controller, each base section connector reversibly mating with a corresponding one of said light generating section connectors.
