Solid State Lamp Using Modular Light Emitting Elements
First Claim
1. A solid state lamp comprising:
- a base portion having an electrical connector for connection to a source of power;
a plurality of receptacles on the base for receiving a plurality of modules containing light emitting diodes (LEDs) and providing drive current to the LEDs; and
a plurality of modules, each module having electrical connectors for connection to associated receptacles on the base, the receptacles supporting the modules when the modules are electrically connected to the receptacles,wherein the modules and base are configured to allow a user to select a number of modules to connect to the base and to operate the lamp with different combinations of modules to generate a desired light output from the lamp.

Abstract
A solid state lamp, such as one that can replace an incandescent light bulb, has a base portion having an electrical connector for connection to a source of power, such as an Edison-type connector for connection to the mains voltage. An AC/DC converter in the base converts the mains voltage to a suitable light emitting diode (LED) drive voltage. A plurality of receptacles on the base connects to electrodes of plug-in modules. Each plug-in module supports a plurality of low power LEDs connected in series. The strings of LEDs on different modules are connected in parallel when connected to the receptacles. The modules and base are configured to allow a user to operate the lamp with different combinations of modules to generate a desired light output from the lamp. For example, the user can recreate the lumens equivalent of a 20 W, 40 W, or 60 W bulb by using one, two, or three modules.
