Ubuhlalu besibani se-LED Izindlela zokuxhuma ezivame ukusetshenziswa

Ifomu lokumisa le-LED kuhlelo lokusebenza lincike ezintweni eziningi, okuhlanganisa amapharamitha we-LED nobuningi, i-voltage yokufaka, ukusebenza kahle, ukuphathwa kokukhipha ukushisa, usayizi nemikhawulo yesakhiwo kanye ne-optics, njll. Ifomu elilula lokumisa i-LED eyodwa. Ngenxa yokuthi izindiza ngokuvamile ziyadingeka ngezikhathi zangempela zokufaka isicelo, ama-LED amaningi adinga ukuhlelwa futhi ahlanganiswe njengoba kudingeka ukuze ahlangabezane nezidingo zohlelo lokusebenza lwezinga elikhulu, ukukhanya okuphezulu, isibonisi esiguqukayo, ukuguqulwa kombala, kanye nezidingo ezifanayo ze-LED nabashayeli abasekelayo. I. Ifomu lokuxhumana ngokuphelele 1. Amafomu ochungechunge olula ngokuvamile axhunywe ku-LED1 LEDN ngendlela yamafomu oxhumano oluwuchungechunge olulula, futhi agelezayo amanje phakathi ne-LED ayalingana. Kuma-LED anezincazelo ezifanayo namaqoqo, nakuba i-voltage ku-LED eyodwa ingase ibe nomehluko omncane, ngoba i-LED iyidivayisi yamanje, ingaqinisekisa ukuthi ukuqina kwawo okukhanyayo kuyahambisana. Ngakho-ke, uchungechunge olulula lwama-LED lunezici zamasekethe alula nokuxhumana okulula nezinye izici. (Ukungalungi: Ngenxa yokusetshenziswa kochungechunge, lapho enye ye-LED ihluleka, zonke izibani ze-LED zizocinywa, okuzothinta ukuthembeka kokusetshenziswa. ) 2. Amafomu ochungechunge e-two-pole diode nenhlanganisela ye-Qina diode axhunywe ochungechungeni oluthuthukisiwe lokuxhuma lwe-Qina diode ngokuhambisana. Kule ndlela yokuxhuma, i-voltage yokuwohloka ye-Zina diode ngayinye iphakeme kune-voltage yokusebenza ye-LED. Uma usebenza ngokujwayelekile, ngenxa yokuthi i-Qina diode VD1 VDN ayishayeli, okwamanje igeleza ku-LED1 LEDN. Lapho i-LED eyonakele ochungechungeni lwe-LED ibangelwa Ngaphezu kwe-LED, amanye ama-LED asenemisinga edlulayo futhi ekhanyayo. I-akhawunti yomphakathi ye-WeChat: I-Shenzhen LED Chamber of Commerce (le ndlela yokuxhuma kanye nefomu lochungechunge olulula kuthuthukise kakhulu ukwethembeka mayelana nokwethembeka. ) Okwesibili, ifomu elihambisanayo eliphelele 1. Ifomu elihambisanayo elilula, elilula futhi elixhumene ne-LED1 yomsila wekhanda le-LEDN elihambisanayo, i-LED ngayinye ilingana ne-voltage efanayo, i-voltage elinganayo. Ingabonakala ezicini ze-LED. Ingeyedivayisi yamanje, futhi izinguquko ezincane ku-voltage engezwe ku-LED zizodala ushintsho olukhulu lwamanje. Ngaphezu kwalokho, ngenxa yokulinganiselwa kobuchwepheshe bokukhiqiza be-LED, ngisho nenqwaba efanayo yama-LED, kukhona umehluko ekusebenzeni. Ngakho-ke, lapho i-LED1 LEDN isebenza, yamanje egeleza ku-LED ngayinye ayilingani. Kungabonakala ukuthi ukusatshalaliswa okungalingani kwe-LED ngayinye yamanje kungabangela impilo ye-LED yamanje ukuthi ibe nkulu kakhulu, futhi ishise imbala. (Ukubi: Nakuba le ndlela yokuxhuma ilula, kodwa ukwethembeka akuphakeme, ikakhulukazi izinhlelo zokusebenza esimweni senani elikhulu lama-LED. ) 2. Ifomu elihambisanayo lokufanisa okuzimele lihloselwe ukuthembeka kokufana okulula. Ifomu elihambisanayo elizimele liyindlela enhle. I-LED ngayinye ngale ndlela ine-adjustable yamanje (i-drive Voutput terminal i-L1 Ln) ukuqinisekisa ukuthi okwamanje ogeleza nge-LED ngayinye ingaphakathi kwezidingo zayo, ngemiphumela emihle yokushayela, ukuvikelwa kwe-LED okukodwa Okuphelele, akuthinti enye i-LED. isebenze uma inamaphutha, futhi ingafanisa izici zama-LED anomehluko omkhulu. (Okubi: Ukwakhiwa kwesekethe yomshayeli kuyinkimbinkimbi, izindleko zedivayisi ziphezulu, ivolumu ithatha kakhulu, ayifanele inani elikhulu lamasekethe e-LED. ) Okwesithathu, uhlobo oluxubile lokubunjwa okuxubile luhlongozwa ngokuhlanganisa izinzuzo ezifanele zochungechunge kanye namafomu ahambisanayo. Amafomu amakhulu yilawa amabili alandelayo. 1. Lapho amafomu okwakheka okuxubile eqala, lapho inani lezinhlelo zokusebenza ze-LED likhulu, uchungechunge olulula noma uxhumano oluhambisanayo alunangqondo, ngoba okokuqala kudinga umshayeli ukuthi akhiphe i-voltage ephezulu (izikhathi ezingu-N ze-voltage eyodwa ye-LED VF), kanti lena yokugcina idinga umshayeli ukuthi adinge umshayeli Khipha umsinga omkhulu (izikhathi ezingu-N ze-LED yamanje eyodwa uma). Lokhu kuletha ubunzima ekwakhiweni nasekukhiqizeni umshayeli, futhi kuhilela izinkinga zesakhiwo kanye nokusebenza kahle jikelele kwesekethe yokushayela. I-voltage yenani lama-LED ochungechungeni kanye ne-voltage yokusebenza ye-LED VF eyodwa inquma i-voltage ephumayo yedivayisi yokushayela; Inani linquma amandla okukhipha omshayeli. Ngakho-ke, indlela yokuxuba ngemva kokuxuba ngokuyinhloko iwukuqinisekisa ukuthi kunokwethenjelwa okuthile (iphutha le-LED entanjeni ngayinye lithinta kuphela ukukhanya okuvamile kwentambo), nokumataniswa kwesekethe yedrayivu ), Ithuthukisa ukwethembeka kunamafomu ochungechunge olula. . I-akhawunti yomphakathi ye-WeChat: I-Shenzhen LED Chamber of Commerce (isifunda sonke sinezici zesakhiwo esilula, uxhumano olulula, ukusebenza kahle okuphezulu, njll., kufanelekile izinhlelo zokusebenza ezinenani elikhulu lama-LED. ) 2. Ama-LED amaningana axutshwe neyunithi yezinhlamvu kuqala, kanye nezinhlobo ezixubile zokuxhuma ngaphambi kweyunithi yezinhlamvu. Njengoba i-LED1-N LEDM-N ixhunywe okokuqala ukuxhuma, okuthuthukisa ukuthembeka kweqembu ngalinye lama-LED, kodwa lokhu kubalulekile. Ngenxa yalesi sizathu, ungakhetha i-voltage esebenzayo kanye neyamanje ngangokunokwenzeka njengeqembu elihambisanayo ngokumatanisa, noma ukuxazulula ukumelana okuncane kwamanje kwe-LED ngayinye. (Ezinye izici zaleli fomu lokwakheka okuxubile kanye nezinkinga ezikhona ziyefana. ) Okwesine, izinhlobo eziphambanayo zamalungu afanayo aphambene ikakhulukazi ezokuthuthukisa ukuthembeka komsebenzi we-LED nokunciphisa izinga lokuhluleka. Indlela eyinhloko yokuqamba ithi: uchungechunge ngalunye lwama-LED angu-3 njengeqembu, kanye namatheminali okukhiphayo e-VA, VB, kanye ne-VC axhunywe ekuphumeni kwedrayivu yedrayivu. Uma ama-LED angu-3 ochungechunge ejwayelekile, ama-LED angu-3 akhanya ngesikhathi esifanayo; uma i-LED eyodwa noma amabili engasebenzi, ingaqinisekisa ukuthi okungenani i-LED eyodwa isebenza ngokujwayelekile. Ngale ndlela, ingathuthukisa kakhulu ukuthembeka kweqembu ngalinye lokukhanya kwe-LD, futhi ingathuthukisa ukwethembeka okuphelele kwakho konke ukukhanya kwe-LED. Isifinyezo: Amafomu okuxhuma ahlukene anezici zawo ezihlukene, futhi izidingo zomshayeli zihlukile, ikakhulukazi uma i-LED eyodwa yehluleka ukwehluleka umsebenzi wesifunda, ukwethembeka okuphelele kokukhanyisa, ikhono lokuqinisekisa i-LED jikelele ngangokunokwenzeka, ikhono lokuqhubeka nokusebenza ngangokunokwenzeka, ikhono lokuqhubeka nokusebenza, Kubaluleke kakhulu ukunciphisa ukusebenza kahle kokuhluleka kwe-LED jikelele, njll. Sekukonke, izinhlelo zokusebenza zeqembu le-LED ziyindlela ebalulekile yezinhlelo zokusebenza zangempela ze-LED. Ukuxhumana okuhlukile kwe-LED kubalulekile kuma-LED amakhulu kanye nezidingo zedizayini zamasekethe okushayela. Ngakho-ke, ekuhlanganisweni kwamasekethe angempela, ukukhetha okulungile kwendlela yokuxhuma i-LED ehambisanayo kubaluleke kakhulu ekuthuthukiseni umphumela wokukhanya kwayo, ukwethembeka komsebenzi, ukuklama nokukhiqiza umshayeli kube lula, kanye nokusebenza kahle komshini. isifunda sonke.
