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 modules, each module of the plurality of modules comprising multiple light emitting diodes (LEDs), andtwo opposing surfaces through which the module emits light; and
a plurality of receptacles on the base portion configured to receive the plurality of modules and to provide drive current to the multiple LEDs in each of the plurality of modules,wherein each module of the plurality of modules has electrical connectors to connect to associated receptacles on the base portion, the receptacles supporting the modules when the modules are electrically connected to the receptacles,wherein the modules and base portion are configured to allow a user to select a number of modules to connect to the base portion 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.

19. A method of controlling light output from a solid state lamp, the lamp comprising a base portion having an electrical connector to connect to a source of power, and a plurality of receptacles on the base portion to receive a plurality of modules, each module of the plurality of modules including (i) multiple light emitting diodes (LEDs), (ii) two opposing surfaces through which the module emits light, and (iii) electrical connectors to connect the module to an associated receptacle from among the plurality of receptacles on the base portion, the method comprising:
-
supporting the plurality of modules, each module having electrical connectors for connection to associated receptacles on the base portion, the receptacles supporting, by the plurality of receptacles, the plurality of modules that are electrically connected to the plurality of receptacles; and plugging in any of multiple combinations of the plurality of modules into the plurality of receptacles to generate a desired light output from the lamp.
