Filed:

May 7, 2012

Appl. No.:

13/465149

Inventors:

Anil Tipirneni - Boise ID, US
Rui Zhang - Strongsville OH, US

Assignee:

MICRON TECHNOLOGY, INC. - Boise ID

International Classification:

H05B 37/02
H01J 9/42

US Classification:

315151, 445 3

Abstract:

A lighting system includes a solid state lighting device capable of generating mixed light and a controller. The solid state lighting device includes light sources for producing mixed light and a sensor configured to detect light from one of the light sources. The controller controls two or more of the light sources based on output from the sensor. The controller can communicate with the sensor to provide closed-loop control.

Abstract:

Emission systems having solid-state transducers (SSTs) for producing a target chromaticity of light are disclosed herein. An emission system or SST device in accordance with a particular embodiment can include a first emitter having a first plurality of SSTs positioned to emit light having a first chromaticity, and a second emitter having a second plurality of SSTs positioned to emit light having a second chromaticity different than the first chromaticity. The SST device can further include a controller having a first channel with a variable output, coupled to the first emitter to adjust the brightness level of the first emitter, and a second channel with a variable output, coupled to the second emitter to adjust the brightness level of the second emitter.
