Kwintsimi yokupakishwa kwe-LED, i-COB imele i-Chip kwiBhodi, iteknoloji yomthombo wokukhanya odibeneyo odibanisa ii-chips ze-LED ngqo kwi-substrate.Umthombo wokukhanya kwe-LED usebenzisa itekhnoloji ye-COB, i-chip ichitha ngokuthe ngqo ubushushu kwi-substrate, ukumelana noxinzelelo lwamandla aphezulu obushushu;ilungiselelo le-chip dense, ukuxinana kwamandla aphezulu;Ubungakanani bomzimba obunye obukhanyayo buncinci, bulungele indawo yokuthengisa izibane kunye neemfuno ezingqongqo kubungakanani bomthombo wokukhanya.Xa kuthelekiswa nephakeji ye-chip eyodwa yezixhobo ze-LED, iphakheji ye-COB yee-chips ezininzi, ii-solder joints ezininzi, ukuxinana kwamandla aphezulu kuye kwakhokelela ekunyuseni okubonakalayo kubunzima benkqubo yokupakisha.Kunokuthiwa umthombo wokukhanya we-COB kwelinye icala sesona sicelo sikhokelayo sokukhanya kwezorhwebo, kwelinye icala, ikwasisithsaba sendawo yokupakisha ye-LED.
Umsebenzi oyintloko womthombo wokukhanya kukukhanya, ukuba i-LED yongeze umda kwindawo yokukhanyisa - ukonga amandla, ngoko ke isigaba sokuqala sophuhliso lomthombo wokukhanya we-COB sikwajonge ukusebenza kakuhle kokukhanya, ngenxa yomthombo wokukhanya we-COB usebenzisa isinyithi. -Ibhodi yesekethe esekwe okanye i-ceramic substrate reflectivity ayilunganga njengebrakethi ecwecwe ngesilivere, ukubonakaliswa okuphantsi kokukhanya okubekwe ngaphezulu kokufunxwa kokukhanya phakathi kwe-chips ezininzi Ukufunxa, ukukhanya kweCOB komthombo wokukhanya okukhanyayo kusezantsi kunezixhobo ze-SMD ngaphezulu kwe-30%, kwaye kamva Ukwaziswa kwesipili se-aluminium substrate ukusombulula ingxaki yokubonakala, kodwa ukufunxwa okufanayo kweetshiphusi ezininzi kusenza ukuba umthombo wokukhanya okhanyayo we-COB ungaphantsi kunezixhobo ezicacileyo.Ngechipphu ngaphandle kokusebenza kakuhle kwe-quantum kunye nokuguqulwa kokukhanya kokukhanya kwe-phosphor, umthombo wokukhanya okhanyayo we-COB ufikelele ekwamkelweni kweshishini "indawo emnandi" - 100lm / W, ukufika kwale ndawo imnandi kunezixhobo ezidityanisiweyo ezidityaniswe nomthombo wokukhanya kwiminyaka eyi-2-3 kamva.
Kwiimeko ezahlukeneyo, ukutshintsha ubushushu bombala womthombo wokukhanya kunokuzisa amava okukhanya angcono.Xa kungekho mda wendawo, kulula ukuqonda utshintsho lobushushu bombala, okoko nje izixhobo zobushushu eziphakamileyo neziphantsi zixutywe kwaye ziqhutywa ngokwahlukeneyo, utshintsho lobushushu bombala womthombo wokukhanya weCOB lukwayingcamango efanayo, iichips kwi. Umthombo wokukhanya we-COB wohlulwe ngamaqela amabini kwaye uqatywe ngeentlobo ezahlukeneyo kunye nogxininiso lwephosphor exubeneyo, ukuze amaqela amabini eetshiphusi avelise ubushushu bombala ohlukileyo ukukhanya okumhlophe.Guqula ubungakanani bangoku bamaqela amabini chips, unokwenza umthombo wokukhanya ukhuphe ubushushu bombala ohlukeneyo wokukhanya okumhlophe.Ubungakanani obuncinci bomthombo wokukhanya we-COB, emva kokuba ukukhanya kungaboni ubushushu bemibala emibini eyahlukeneyo yendawo yokukhanya, kodwa indawo efanayo yokukhanya, eyona nto iluncedo kumthombo wokukhanya we-COB, kodwa ubungakanani obuncinci, kodwa nakwindawo yokukhanya. ukuveliswa kombala wokuxuba umthombo we-COB wokukhanya kubangele ukudideka okukhulu.Emva kweminyaka yokuphonononga, kwizakhiwo ze-chip ezahlukeneyo, abantu baye baqamba kwaye baphucula itekhnoloji eliqela njengokuprinta, ukutshiza, kunye neetshiphusi ze-fluorescent ukuphumeza isizinda esisisigxina kunye nobuninzi bokugquma kweentlobo ezahlukeneyo zephosphors kwimithombo yokukhanya yeCOB.
Iindidi kunye neereyishini zeentlobo ezimbini zeglue ye-fluorescent yombala wobushushu kumthombo wokukhanya we-COB wokulungisa umbala uphuculwe ukufikelela kwisalathiso esibonakalayo esiphakamileyo kunye nokusebenza okuphezulu kokukhanya kulo lonke uluhlu lokutshintsha kombala.Umzobo we-2 ubonisa i-spectral curves yokushisa kombala ophezulu kunye nomgangatho ophantsi we-COB oguqula umbala womthombo wokukhanya onikezelwe yi-LightSense Semiconductor.I-phosphor yalo mthombo wokukhanya iphuculwe ukwenzela ukuba isalathisi sokunikezelwa kombala sifikelele ngaphezu kwe-95 nakweyiphi na iqondo lokushisa lombala ngexesha lenkqubo yokutshintsha umbala we-3000-6000K, kunye ne-R9 index, eyona nto ixhalabisayo, inkulu kune-80.
Uhlengahlengiso lobushushu bombala lwandisa indawo yesicelo somthombo wokukhanya we-COB, kodwa umbala ofunyenwe kumzobo we-gamut wombala unokuvela kuphela kumbala ophakamileyo nophantsi wolungelelwaniso lombala wobushushu kumgca onamachaphaza.Kwintsimi yokukhanya kwezorhwebo, ukusetyenziswa kolungelelwaniso lwemibala eyahlukeneyo yomthombo wokukhanyisa, unokugqamisa isiphumo esibonakalayo semibala eyahlukeneyo yeempahla ukuhlangabezana neemfuno zobuhle babantu, ukusuka kulo mbono, ukulungiswa kobushushu bombala kuphela okanye akwanelanga, kwi. kule meko, kunye nokukwazi ukulungisa umbala we-gamut yomthombo wokukhanya we-COB wazalwa.
