Abstract
A light emitting device, includes a light emitting diode unit on a substrate; a gas-generating species; an inert gas; a barrier; and a sealant; wherein: the sealant, barrier, and substrate define a protective chamber; and the light emitting diode unit, the gas generating species, and the inert gas are disposed within the chamber.
Claims29
A light emitting device, comprising:
- a light emitting diode unit deposited on to a substrate, the light emitting diode unit comprising a cathode comprising 40K or an alloy of 40K;
- a gas-generating species;
- a barrier;
- and
- a sealant;
- wherein:
- the sealant, barrier, and substrate define a protective chamber;
- the light emitting diode unit, the gas generating species, and an inert gas are disposed within the protective chamber;
- and
- the gas generating species comprises 40K, a carbodiimide, an azo-compound, a cyanamide, a trizaole, an isocyanate or a combination of any two or more thereof.
