Ukukhanya kuphela komthombo wokukhanya ofumaneka ngaphakathi ebusuku. Ekusetyenzisweni kwekhaya imihla ngemihla, impembelelo yemithombo yokukhanya ye-stroboscopic ebantwini, ingakumbi abantu abadala, abantwana, njl. icacile. Nokuba kufundwa kwigumbi lokufundela, kufundwa, okanye kuphumle kwigumbi lokulala, imithombo yokukhanya engafanelekanga ayinciphisi nje kuphela ukusebenza kakuhle, kodwa ukusetyenziswa ixesha elide kunokushiya ingozi efihlakeleyo kwimpilo.

I-Lightman yazisa abathengi ngendlela elula yokuqinisekisa umgangatho weIzibane ze-LEDSebenzisa ikhamera yefowuni ukuze ulungelelanise umthombo wokukhanya. Ukuba i-viewfinder inemigca eguquguqukayo, isibane sinengxaki "ye-strobe". Kuyaqondakala ukuba le nto ye-stroboscopic, ekunzima ukuyiqonda ngeliso lenyama, ichaphazela ngqo impilo yomzimba womntu. Xa amehlo evezwa kwindawo ye-stroboscopic ebangelwa zizibane ezingaphantsi ixesha elide, kulula ukubangela iintloko ezibuhlungu kunye nokudinwa kwamehlo.

Umthombo wokukhanya we-stroboscopic ngokuyintloko ubhekisa kutshintsho oluphindaphindeneyo nolwexesha lokukhanya okukhutshwa ngumthombo wokukhanya ngokukhanya okwahlukileyo kunye nombala ngokuhamba kwexesha. Umgaqo wovavanyo kukuba ixesha lokuvala ifowuni ephathwayo likhawuleza kune-24 frames/sec continuous dynamic flashing enokubonwa liliso lomntu, ukuze i-stroboscopic engabonakaliyo emehlweni iqokelelwe.

I-Strobe inemiphumo eyahlukeneyo kwimpilo. I-American Epilepsy Work Foundation ibonise ukuba izinto ezichaphazela ukuqaliswa kwe-photosensitivity epilepsy ziquka ukuphindaphindeka kwe-scintillation, amandla okukhanya, kunye nobunzulu be-modulation. Kuphononongo lwethiyori ye-epithelial ye-photosensitive epilepsy, uFisher et al. babonise ukuba izigulana ezine-epilepsy zinethuba eliyi-2% ukuya kwi-14% lokubangela ukuxhuzula ngenxa yokukhuthazwa kwemithombo yokukhanya ye-scintillation. I-American Headache Society ithi abantu abaninzi abaneentloko ezibuhlungu ze-migraine banomdla ngakumbi ekukhanyeni, ngakumbi ukukhanya okukhanyayo, imithombo yokukhanya ekhanyayo ene-flicker inokubangela i-migraine, kwaye i-low frequency flicker inzima kakhulu kune-high frequency flicker. Ngelixa befunda impembelelo ye-flicker ekudinweni kwabantu, iingcali zifumanise ukuba i-flicker engabonakaliyo inokuchaphazela indlela yeliso, ichaphazele ukufunda kwaye ikhokelele ekuboneni okunciphileyo.
