LAMP USING SOLID STATE SOURCE

摘要

A lamp includes a single string of light emitting diodes (LEDs), driven in common, configured to cause the lamp to emit a visible light output via a bulb. The lamp also includes a lighting industry standard lamp base, which has connectors arranged in a standard three-way lamp configuration, for providing electricity from a three-way lamp socket. Circuitry connected to receive electricity from the connectors of the lamp base as standard three-way control setting inputs drives the string of LEDs. The circuitry is configured to detect the standard three-way control setting inputs and to adjust the common drive to the string of LEDs to selectively produce a different visible light outputs of the lamp via the bulb responsive to the three-way control setting inputs. The lamp may also include nanophosphors pumped by emissions of the LEDs, so that the lamp produces a white light output of particularly desirable characteristics.

1. A light engine, comprising:
a solid state source comprising a plurality of light emitting diodes (LEDs); a lighting industry standard lamp base, including connectors arranged in a standard three-way lamp configuration, for providing electricity from a three-way lamp socket; a housing mechanically connected to the lamp base; and circuitry in the housing connected to receive electricity from the connectors of the lamp base as standard three-way control setting inputs and to drive the LEDs, wherein the circuitry is configured to detect the standard three-way control setting inputs and to adjust the drive to the LEDs to selectively produce a plurality of different outputs responsive to the three-way control setting inputs.
