Soliton Pair

The numerical solutions of gray spatial solitons supported by linear and quadratic electro-optic (EO) effects in two-photon photorefractive (PR) media are deduced. The characteristics of the gray spatial soliton, soliton pair and soliton family are investigated by numerical method. The full width at half maximum of the gray spatial soliton increases gradually with the increase of the grayness, but decreases gradually with the increase of the soliton optical intensity and external electric field. Also, every soliton component in the gray–gray soliton pair or soliton family has the same full width at half maximum.

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.
