Yiyiphi eyona ingcono, intambo yokukhanya kwe-cob okanye i-LED strip yokukhanya, indlela yokukhetha?

Ukongeza, izibane ze-COB kunye nezibane ze-LED zikwahluke ngokubhekiselele ekusebenzeni kokukhanya, ukufana kunye nokukhanya. Ngenxa yokuba izibane ze-COB zipakisha iitshiphusi ze-LED ezininzi kwi-substrate enye, zinokukhanya okuphezulu okuphezulu kunye nombala wokukhanya ofanayo. I-bead yesibane se-LED yenziwe yi-PN junction, ngoko ke ukukhanya kunye nokusebenza kakuhle kokukhanya kuphantsi.

Izinto eziluncedo kunye nokungahambi kakuhle kwezibane zeCOB kunye nezibane ze-LED

Izinto eziluncedo kwizibane zeCOB:

1. Ukukhanya okuphezulu kokukhanya. Ukusebenza okukhanyayo kwezibane ze-COB malunga ne-30% ephezulu kuneyezibane ze-LED, ngoko ke phantsi kwamandla afanayo, izibane ze-COB zikhanya ngakumbi.

2. Umbala okhanyayo ufana. Ngenxa yokuba izibane ze-COB zipakisha iitshiphusi ze-LED ezininzi kwi-substrate enye, umbala okhanyayo ufana ngakumbi.

3. Ukonga amandla kunye nokukhuselwa kwendalo. Izibane ze-COB zinokukhanya okuphezulu kwaye zinokufikelela kwiziphumo eziphezulu zokonga amandla; ngelo xesha, ngenxa yokuba akukho zixhobo ezinobungozi ezifana ne-mercury ezisetyenziselwa inkqubo yokuvelisa izibane ze-COB, zihambelana nokusingqongileyo ngexesha lokusetyenziswa.

2. Iikhalori eziphezulu. Ekubeni izibane ze-COB zivelisa ubushushu obukhulu ngexesha lokusebenza, unyango lokutshatyalaliswa kobushushu luyafuneka.

Izinto eziluncedo kunye nokungonakali kwezibane ze-LED

Izinto eziluncedo kwizibane ze-LED:

1. Ubomi obude. Ubomi bezibane ze-LED bunokufikelela kwiiyure ezingaphezu kwe-50,000, ezide kunezibane zendabuko.

2. Ukukhanya okuphezulu kokukhanya. Nangona ukusebenza okukhanyayo kwezibane ze-LED kuphantsi kunoko kwezibane ze-COB, xa kuthelekiswa nezibane zemveli kunye nezibane ze-fluorescent, ukusebenza okukhanyayo kwezibane ze-LED kusephezulu.

3. Ukukhanya kombala wokukhanya. Umbala okhanyayo wezibane ze-LED ugcwele ngakumbi kuneebhalbhu zokukhanya zendabuko kunye nezibane ze-fluorescent, kwaye zinokubonisa imibala ebonakalayo.

Ukungalunganga kwezibane ze-LED:

1. Ukusebenza kokukhanya okuphantsi. Xa kuthelekiswa nezibane ze-COB, izibane ze-LED zinokukhanya okuphantsi kokukhanya.

2. Umbala okhanyayo awulingani. Ekubeni amaso ezibane ze-LED zine-PN enye kuphela, umbala okhanyayo awufani ngokufanayo naleyo yezibane ze-COB.

Yeyiphi engcono, intambo yokukhanya yeCOB okanye isibane sesibane se-LED?

Imichilo yokukhanya ye-COB kunye nemitya yokukhanya ye-LED zizixhobo zokukhanyisa eziqhelekileyo, kwaye zahlukile kwindlela umthombo wokukhanya owenziwe ngayo. Imichilo yokukhanya ye-COB ipakisha iitshiphusi ezininzi ze-LED kwi-substrate efanayo ukwenza umthombo wokukhanya we-semiconductor, ke ukukhanya kuphezulu kwaye umbala okhanyayo ufana ngakumbi. I-strip yokukhanya kwe-LED yenziwe ngamaso amaninzi esibane se-LED. Nangona ukukhanya okusebenzayo kungaphantsi kunesibane se-COB, kunobomi obude.

Ngokuxhomekeke kwimeko yesicelo, ukhetho phakathi kwemichilo yokukhanya ye-COB okanye i-LED strips kufuneka ihluke. Ukuba yindawo yokukhanyisa yorhwebo efuna iimfuno zombala ophezulu, kuyacetyiswa ukuba ukhethe imicu yokukhanya ye-COB. Ukuba yindawo yokukhanyisa yangaphakathi efuna umsebenzi wexesha elide, kuyacetyiswa ukuba ukhethe imicu yokukhanya kwe-LED.

Iimeko zokusetyenziswa kwezibane zeCOB kunye nezibane ze-LED

Izibane zeCOB kunye nezibane ze-LED zineenzuzo ezahlukeneyo kwiimeko ezahlukeneyo zesicelo. Oku kulandelayo luhlalutyo oluvela kwimiba emibini: izibane zentengiso kunye nezibane zangaphakathi:

ukukhanya kwezorhwebo

Izibane zokukhanyisa zorhwebo zifuna iimfuno eziphezulu zemibala, ngoko kuyacetyiswa ukuba ukhethe izibane ze-COB. Ngenxa yokuba izibane ze-COB zipakisha iitshiphusi ze-LED ezininzi kwi-substrate enye, umbala okhanyayo ufana ngakumbi kwaye unokubonisa imibala eyinyani ngakumbi. Kwangaxeshanye, ukukhanya kokukhanya kwezibane ze-COB nako kuphezulu kwaye kunokufikelela kwiziphumo ezingcono zokukhanyisa.

Ukukhanya kwangaphakathi

Izibane zokukhanyisa zangaphakathi zifuna iiyure ezinde zokusebenza, ngoko kuyacetyiswa ukuba ukhethe izibane ze-LED. Nangona ukusebenza okukhanyayo kwezibane ze-LED kuphantsi kunoko kwezibane ze-COB, xa kuthelekiswa nezibane zemveli kunye nezibane ze-fluorescent, ukusebenza okukhanyayo kwezibane ze-LED kusephezulu. Ngelo xesha, ubomi bezibane ze-LED bude, obunokuhlangabezana neemfuno zokukhanya kwangaphakathi ixesha elide.

Iingcebiso zokukhetha izibane zeCOB kunye nezibane ze-LED

Ngokuxhomekeke kwimeko yesicelo, ukhetho phakathi kwezibane zeCOB okanye izibane ze-LED kufuneka zihluke. Ezi zilandelayo zingcebiso zokukhetha kwiimeko ezahlukeneyo:

1. Indawo yokukhanyisa intengiso: Kucetyiswa ukuba ukhethe izibane ze-COB, ezinokuhlangabezana nemfuno yeemfuno eziphezulu zemibala.

2. Iimeko zokukhanyisa zangaphakathi: Kucetyiswa ukuba ukhethe izibane ze-LED, ezinokuhlangabezana neemfuno zokukhanya kwexesha elide.

3. Ezinye iimeko: Khetha izibane zeCOB okanye izibane ze-LED ngokweemfuno zokwenyani.

Imichilo yokukhanya ye-COB kunye nemigca yokukhanya ye-LED nganye ineenzuzo zayo. Yiyiphi eyona ibhetele ixhomekeke kwiimeko ezithile zokusetyenziswa kunye neemfuno.

Kwiimeko zokukhanyisa zorhwebo, imichilo yokukhanya ye-COB inokufaneleka ngakumbi. Ngenxa yokuba izibane zezibane ze-COB zinokukhanya okuphezulu kunye nombala wokukhanya ofanayo, zinokuhlangabezana neemfuno zeemfuno zombala eziphezulu. Ukongeza, umgca wokukhanya we-COB unenkangeleko elula kwaye enhle, enika abantu imvakalelo ebukekayo kunye nemfashini, kwaye ifanelekile kwizibane zokuhombisa kwiindawo zorhwebo.

Nangona kunjalo, kwiimeko zokukhanyisa zangaphakathi, izibane ze-LED zinokufaneleka ngakumbi. Imichilo yokukhanya ye-LED inobomi obude, ukusebenza kakuhle kokukhanya okuphezulu, kwaye inokuhlangabezana neemfuno zokukhanya kwexesha elide. Ukongeza, ixabiso leentambo zokukhanya kwe-LED ngokuqhelekileyo lifikeleleka ngakumbi kuneentambo zokukhanya ze-COB, okwenza ukuba zilungele iintsapho kunye nezinye iindawo apho iindleko ziqwalaselwa.

Ngokuqhelekileyo, iintambo zokukhanya kwe-COB zineenzuzo ezithile ngokubhekiselele ekusebenzeni kokukhanya kunye nokubonakala, kwaye zifanelekile kwiimfuno eziphezulu ezifana nokukhanya kwezorhwebo; ngelixa izibane ze-LED zisebenza ngokugqwesileyo malunga nobomi, iindleko kunye nokukhanya kwexesha elide, kwaye zifaneleke ngakumbi kwiimfuno zemihla ngemihla ezifana nokukhanyisa kwangaphakathi. Xa ukhetha, unokwenza isigqibo esisekelwe kwiimfuno zakho zangempela kunye nohlahlo lwabiwo-mali.
