LED ASSEMBLY WITH COLOR TEMPERATURE CORRECTION CAPABILITY
First Claim
1. An illumination assembly, comprising:
- a substrate comprising a base material and a plurality of coatings applied on a respective plurality of surface portions of the base material, the coatings on the surface portions comprising first and second colors;
a light emitting device mounted on the substrate, the light emitting device further comprisingone or more light emitting elements having a first color temperature and mounted on surface portions of the substrate having the first color coating,one or more light emitting elements having a second color temperature and mounted on surface portions of the substrate having the second color coating, andone or more of said light emitting elements further individually sealed with a resin containing a phosphor excitable by light emitted from the associated light emitting element; and
a reflectance factor of the first color coating and a reflectance factor of the second color coating set corresponding to light emitted from the light emitting elements having the first and second color temperatures, respectively, with respect to a desired color temperature for the light emitting device.

Abstract
An illumination assembly is provided which is capable of correcting a color temperature. The assembly includes a substrate with a plurality of coatings applied on a respective plurality of surface portions of a base material. A light emitting device includes one or more light emitting elements of a first color temperature mounted on surface portions of the substrate having a first color coating, and one or more light emitting elements having a second color temperature mounted on surface portions of the substrate having a second color coating. Light emitting elements are individually sealed with a resin containing an excitable phosphor, with a reflectance factor of the first color coating and a reflectance factor of the second color coating set corresponding to light emitted from the light emitting elements having the first and second color temperatures, respectively, with respect to a desired color temperature for the light emitting device.
