Patent ID: 8492788

Claim:
A light emitting device, comprising: first and second glass substrates, the first and second substrates being substantially parallel and spaced apart so as to define a cavity therebetween; a plurality of pillars disposed between the first and second substrates, wherein the cavity between the first and second glass substrates is at pressure less than atmospheric pressure and the pillars space the first and second substrates from each other; an edge seal provided between the first and second glass substrates, the edge seal for hermetically sealing the cavity between the first and second glass substrates, and the edge seal being located proximate edge portions of the first and second substrates; at least one conductive bus bar disposed on an inner surface of the second glass substrate facing the first glass substrate; a thermoelectric cooling structure comprising at least one n-leg and at least one p-leg in contact with the at least one bus bar; at least one conductor connecting the at least one n-leg and the at least one p-leg; at least one LED supported by the at least one conductor in the cavity between the first and second substrates; and wherein said pillars have a greater height than do the n-leg and the p-leg.
