In the article, the electrical and thermal processes in the LED lamp with varied parameters are investigated. Voltage and current measurements on all LEDs of the luminaire are carried out in the nominal operating mode. The power allocated to each LED is determined. The calculation of the LED crystal temperature was carried out using the developed thermal LED model based on the results of the measurements and by using “Multisim” program. It has been established that the temperature of the crystals of individual LEDs in the luminaire differ significantly, which leads to unfavourable thermal conditions for them and an increased likelihood of premature failure.

The CaO-SiO2-B2O3-Al2O3-La2O3 sealants with different alumina contents were fabricated by high-temperature melting method for intermediate temperature solid oxide fuel cell (ITSOFC). The glass transition temperature (Tg) and crystal temperature (Ts) of the sealant with different alumina content was characterized by TG-DSC. And the composition phase of the sealant was detected by XRD. The resistivity of sealant tested by electrochemical workstation was higher than 22 kΩ·cm2, which met the requirement for ITSOFC. Through the detecting of the wetting angle, the adhesion of sealant and anode materials was very good, and the single cell sealed with alumina tube successfully.
