1. Cabbir yar, kala-baxa kulaylka iyo qudhunka fudud waa dhibaatooyin waaweyn
Lightmanwaxay aaminsan tahay in si loo hagaajiyo qaab-dhismeedka fiilooyinka nalalka fiilooyinka LED, nalalka fiilooyinka LED hadda waxaa ka buuxa gaas aan firfircoonayn si loogu daadiyo kulaylka shucaaca, waxaana jira farqi weyn oo u dhexeeya codsiga dhabta ah iyo saameynta naqshadeynta. Sidoo kale, maadaama fiilooyinka LED ay yihiin jajab qaab xirmo COB ah, isticmaalka qaar ka mid ah hababka farsamada ee wax ku oolka ah si loo yareeyo soo saarista kulaylka ama gudbinta kulaylka degdegga ah waa dammaanad qaadka libdhinta iftiinka hooseeya iyo cimri dheer ee nalalka fiilooyinka LED, sida hagaajinta qaabka substrate-ka iyo walxaha substrate-ka. Xulashada, qaabka shunt-ka thermoelectric, iwm.

2. Si buuxda uma baabi'in karo stroboscopic-ga
Marka laga hadlayo dhibaatada iftiiminta stroboscopic ee laambadaha fiilooyinka LED, lightman wuxuu aaminsan yahay in laambadaha fiilooyinka LED ay yar yihiin cabbirka iyo inay yar yihiin booska rakibidda. Meesha rakibidda xaddidan waxay leedahay shuruudo aad u adag oo ku saabsan mugga qaybaha, haddana waxaa loo isticmaali karaa awood yar iyo meel yar oo rakibid ah. Kaliya xariiqda cadaadiska sare ee badeecada ayaa buuxisa shuruudahan. Sababtoo ah saameynta "godka" ee ay keento toosanaanta danab sare ee marinnada degdegga ah ee hadda, aad bay u adag tahay in la gaaro iftiiminta stroboscopic ee awoodda wax soo saarka ee baaxadda weyn iyadoo la tixgelinayo in tignoolajiyada magdhowgu aysan lahayn habab farsamo oo wanaagsan. Ma jiro stroboscopic gabi ahaanba mana jirto xal dhammaystiran. Kaliya hababka farsamada ayaa loo isticmaali karaa in lagu yareeyo saameynta "godka" iyo in la xakameeyo stroboscopic ilaa meel gaar ah.
