Eminyakeni yakamuva,Izibani zomgwaqo ze-LEDsezithandwa kakhulu ngenxa yokonga amandla nokuqina kwazo. Lezi zibani zenzelwe ukukhanyisa imigwaqo nezindawo zangaphandle ngokukhanya okukhanyayo nokugxilile. Kodwa wake wazibuza ukuthi yini ngempela ngaphakathi kwesibani somgwaqo se-LED? Ake sibheke ukusebenza kwangaphakathi kwalezi zixazululo zokukhanyisa ezisebenza kahle kakhulu.
Uma uqala ukubona, isibani somgwaqo se-LED sibonakala silula. Kodwa-ke, izingxenye zaso zangaphakathi ziyinkimbinkimbi kakhulu. Izingxenye eziyinhloko zezibani zomgwaqo ze-LED zifaka ama-LED chips, ama-driver, ama-heat sink, namadivayisi okukhanya.
Ama-chip e-LED
Ama-chip e-LED ayinhliziyo nomphefumulo wezibani zasemgwaqweni. Lawa madivayisi amancane e-semiconductor ayakhanya lapho ugesi udlula kuwo. Ubuchwepheshe be-LED bushintshe imboni yokukhanyisa ngokunikeza ukusebenza kahle kwamandla okuphezulu kanye nokuphila isikhathi eside. Ama-chip e-LED asetshenziswa ezibani zasemgwaqweni enziwe nge-gallium nitride, into ekhiqiza ukukhanya okukhanyayo, okuqondisa isiqondiso.
Umshayeli we-SPD
Umshayeli ungenye ingxenye ebalulekile yezibani zasemgwaqweni ze-LED. Ulawula ugesi wama-chip e-LED, uqinisekisa ukuthi athola i-voltage kanye nogesi ofanele. Abashayeli be-LED baklanyelwe ukuguqula ugesi oshintshashintshayo (AC) kusuka kokufakwayo kwamandla kuya kugesi oqondile (DC) odingwa yi-LED. Banikeza nemisebenzi ehlukahlukene yokulawula, njengokufiphaza kanye nokulungiswa kombala, okuvumela ukuguquguquka okukhulu ekwakhiweni kokukhanya kanye nokonga amandla.
Usinki oshisayo
Izitsha zokushisa zidlala indima ebalulekile ekugcineni impilo yezibani zasemgwaqweni ze-LED. Ngenxa yokusebenza kahle kakhulu kwezitsha ze-LED, zikhiqiza ukushisa okuncane kunemithombo yokukhanya yendabuko. Kodwa-ke, ukushisa okweqile kusenganciphisa impilo nokusebenza kwe-LED. Isitsha sokushisa, esivame ukwenziwa nge-aluminium, sinesibopho sokuqeda ukushisa okweqile nokuvimbela i-LED ekushiseni ngokweqile. Ngokuqinisekisa ukuphathwa okwanele kokushisa, izitsha zokushisa zandisa ukuthembeka nokuqina kwezibani zasemgwaqweni.
I-Optics
Ama-Optical ezibanini zasemgwaqweni ze-LED alawula ukusatshalaliswa kanye nokuqina kokukhanya. Asiza ekuqondiseni ukukhanya kusuka kuma-chip e-LED kuya endaweni oyifunayo ngenkathi enciphisa ukungcola kokukhanya kanye nokukhanya okukhanyayo. Amalensi kanye nama-reflector avame ukusetshenziswa ekukhanyeni komgwaqo ukuze kufezwe ukusatshalaliswa kokukhanya okunembile, okwandisa ukumbozwa kokukhanya kanye nokusebenza kahle. Ama-Optical avumela ukulawula okunembile kwemisebe yokukhanya okulinganayo emigwaqweni nasezindaweni zangaphandle.
Iyunithi yamandla
Ngaphezu kwalezi zingxenye eziyinhloko, kunezinye izinto ezisekelayo ezifaka isandla ekusebenzeni kwezibani zasemgwaqweni ze-LED. Iyunithi yamandla inesibopho sokulawula nokwenza ngcono amandla anikezwa umshayeli. Iqinisekisa ukusebenza okuzinzile kungakhathaliseki ukuthi ugesi unikezwa noma ukushintshashintsha okungenzeka.
Izivalo ezivikelayo nezivalo
Ngaphezu kwalokho, izindawo zokuvikela kanye nezindawo zokuvikela zivikela izingxenye zangaphakathi ezintweni zemvelo ezifana nomswakama, uthuli, kanye nokushintsha kwezinga lokushisa. Izibani zasemgwaqweni ze-LED zenzelwe ukumelana nezimo zezulu ezinzima, ukuqinisekisa ukusebenza okuthembekile ngisho nasezimweni ezimbi kakhulu.
Ngombono wami
Intuthuko kwezobuchwepheshe bokukhanyisa imigwaqo ye-LED ishintshe indlela esikhanyisa ngayo imigwaqo yethu nezindawo zangaphandle. Uma kuqhathaniswa nezixazululo zokukhanyisa zendabuko, izibani zemigwaqo ze-LED zingonga amandla amakhulu, ngaleyo ndlela zinciphise ukusetshenziswa kukagesi kanye nokukhishwa kwekhabhoni. Ngaphezu kwalokho, impilo yazo yesevisi ende inciphisa isidingo sokufakwa kabusha njalo, okunegalelo ekongeni izindleko ezinkulu komasipala nasemiphakathini.
Ngaphezu kwalokho, ukuqondiswa kwama-LED kuqinisekisa ukusatshalaliswa kokukhanya okunembile, kunciphisa ukungcola kokukhanya futhi kunciphisa ukungakhululeki kwezakhamuzi. Lobu buchwepheshe bokukhanyisa obusebenzayo buguqula indawo yasemadolobheni, buhlinzeka ngemigwaqo ephephile nekhanyiswe kahle yabahamba ngezinyawo nabashayeli bezimoto.
Ngokufigqiwe
Izibani zasemgwaqweni ze-LED zakhiwe yizingxenye ezahlukahlukene eziyinkimbinkimbi ezisebenza ndawonye ukuhlinzeka ngokukhanya okonga amandla nokuthembekile. Ama-chip e-LED, ama-driver, ama-heat sink, kanye nama-optics ahlangana ukudala ikhambi lokukhanyisa elisebenza kahle nelihlala isikhathi eside. Njengoba ubuchwepheshe be-LED buqhubeka nokuthuthuka, singabheka phambili ezinkethweni zokukhanyisa zasemgwaqweni ezisebenza kahle nezintsha esikhathini esizayo.
Uma unesifiso sokukhanyisa izibani zasemgwaqweni, wamukelekile ukuxhumana nomkhiqizi wezibani ze-solar led uTIANXIANG ku-Funda kabanzi.
