Abstract

See full text

Patterned ceramic wavelength-converting phosphor structures may be bonded to an LED to form a pcLED. The phosphor structures are patterned with features that provide enhanced oxygen permeability to an adhesive bond used to attach the phosphor structure to the LED. The enhanced oxygen permeability reduces transient degradation of the pcLED occurring in the region of the adhesive bond.
