Title:
COLOR TUNING OF LIGHT-EMITTING DEVICES
Document Type and Number:
WIPO Patent Application WO/2014/144706
Kind Code:
A3
Abstract:
A variety of light-emitting devices for general illumination utilizing solid state light sources (e.g., light-emitting diodes) are disclosed. A light-emitting device can include a first light-emitting element (LEE) for emitting light having a first spectral composition, a second LEE for emitting light having a second spectral composition, and a scattering element surrounding at least in part the first and second LEEs to scatter light emitted from the first and second LEEs. The light-emitting device can also include electrical connections for connecting the first and second LEEs to a power source, where the electrical connections are arranged such that power to the first LEE is separately adjustable relative to power to the second LEE.
