Nguwuphi umahluko phakathi kwemichilo yokukhanya kwe-cob kunye nemicu yokukhanya ye-LED eqhelekileyo?

Umahluko phakathi kwemichilo yokukhanya kwezikhwebu kunye nemicu ye-LED

Ziziphi izibane ze-LED kunye nezibane zeCOB

Isibane se-LED, igama elipheleleyo sisibane se-diode esikhanyayo, ngumthombo wokukhanya we-semiconductor. Yenziwe sisiphambuka se-PN. Xa ii-electron kunye nemingxuma zidibanisa kwakhona kwi-PN junction, ukukhutshwa kokukhanya kwenzeka. Izibane ze-LED zineenzuzo zokusebenza okuphezulu, ubomi obude, umbala okhanyayo ogcweleyo, ukonga amandla kunye nokukhuselwa kwendalo, njl., ngoko ke zisetyenziswa ngokubanzi ekukhanyeni, ekuboniseni, ekuboniseni, kwisignali nakwezinye iindawo.

Isibane se-COB, esimele i-chip packaged lamp bead, luhlobo olutsha lomthombo wokukhanyisa. Ipakisha iitshiphusi ze-LED ezininzi kwi-substrate enye ukwenza umthombo wokukhanya we-semiconductor ukuze uthabathele iintsimbi zesibane ze-LED zemveli, ngaloo ndlela ufezekise ukusebenza kakuhle kokukhanya kunye nokukhanya okuphezulu. Izibane ze-COB zineenzuzo zokukhanya okuphezulu, umbala wokukhanya okufanayo, kunye nokukhanya okuphezulu, ngoko ke zisetyenziswa ngokubanzi ekukhanyeni kwezorhwebo, ukukhanya kwangaphakathi kunye nezinye iindawo.

1. Isakhiwo somthombo wokukhanya

I-COB (i-Chip kwiBhodi) isibane sokukhanya sisibane esidibanisa ii-chips ezininzi ze-LED kwi-substrate. Iichips ezininzi ze-LED kwi-substrate zicwangciswe ecaleni ukuze zenze yonke into, kwaye indawo ekhupha ukukhanya iyaqhubeka kwaye ifana. I-LED (i-Light Emitting Diode) isibane esikhanyayo sicwangcisa iitshiphusi ze-LED enye ecaleni kumtya wokukhanya. Ke ngoko, isiseko somthombo wokukhanya we-COB imitya yokukhanya ixinene kwaye idityanisiwe, ngelixa umthombo wokukhanya wemigca yokukhanya ye-LED ihlakazekile ngakumbi.

2. Ukuqaqamba

Ngenxa yokuba isiseko somthombo wokukhanya we-COB imicu yokukhanya ihlangene ngakumbi, xa iichips ze-LED ezininzi zisebenza ngaxeshanye, indawo ekhupha ukukhanya inkulu kwaye ukukhanya kuphezulu. Njengoko umthombo wokukhanya wemigca yokukhanya ye-LED ihlakazekile kwaye iitshiphusi ze-LED zomntu zincinci, ukukhanya kwazo kuphantsi. Ke ngoko, xa ukukhanya okuphezulu okukhanyayo kufuneka, kufanelekile ukukhetha imicu yokukhanya ye-COB.

3. Ukusebenza kakuhle kwamandla

Isiphumo sokukhanyisa se-COB singcono kakhulu, ukukhanya kufana, umphumo wokubonakalisa unamandla, kwaye ukusebenza kakuhle kwamandla kuphezulu. Ngenxa yokuxinana kwesakhiwo somthombo wokukhanya, imichilo yokukhanya ye-COB inokulawula ngcono isalathiso sokukhanya kunye nokunciphisa ukulahleka kwamandla ngexesha lenkqubo yokukhanyisa. Nangona kunjalo, amandla ombane okukhanya kwe-LED aphantsi kakhulu ngenxa yemithombo yokukhanya ehlakazekileyo ngexesha lenkqubo yokukhanyisa.Ngoko ke, ngelixa uphishekela ukusebenza kakuhle kwamandla, ukukhetha imichilo yokukhanya kwe-COB kunokugcina amandla kunye nokunciphisa iindleko zokukhanyisa.

4. Ixabiso

Ngenxa yokuba izibane zokukhanya ze-COB zifuna iinkqubo eziphezulu zemveliso kwaye zineziphumo zokukhanya ezingcono kunye nokusebenza kakuhle kwamandla, amaxabiso abo aphezulu. Ixabiso leentambo zokukhanya ze-LED liphantsi ngenxa yenkqubo yabo yokuvelisa elula. Ngoko ke, xa uhlahlo lwabiwo-mali lulinganiselwe, kunokuba luqoqosho ngakumbi ukukhetha imicu yokukhanya kwe-LED.

Iimeko ezintlanu 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.

Ukushwankathela, kukho umahluko ocacileyo phakathi kwemichilo yokukhanya ye-COB kunye nemigca yokukhanya ye-LED ngokwesakhiwo somthombo wokukhanya, ukukhanya, ukusebenza kakuhle kwamandla kunye nexabiso. Imicu yokukhanya ye-COB ineengenelo zesakhiwo somthombo wokukhanya obambeneyo, ukukhanya okuphezulu kunye nokusebenza kakuhle kwamandla aphezulu, kwaye zifanelekile kwizihlandlo ezifuna ukukhanya okuphezulu kokukhanya kunye nokonga amandla. Izibane zokukhanya kwe-LED zinenzuzo yamaxabiso aphantsi, kwaye zinokuhlangabezana neemfuno ezithile zokukhanyisa phantsi kweemfuno ezithile zokukhanyisa. Ngoko ke, xa ukhetha imichilo yokukhanya, kufuneka uqwalasele ngokubanzi ngokusekelwe kwiimfuno ezithile kunye nohlahlo lwabiwo-mali ukwenza ukhetho olufanelekileyo.
