I-LED Multi-layer Electronic Sirens kanye Nolwazi Oluyisisekelo Lwezipikha
Ulwazi oluyisisekelo lwe-LED olunezingqimba eziningi ze-Electronic kanye nezipikha
1: I-LED enezingqimba eziningi ze-Electronic Sirens nezipikha, kufaka phakathi ama-chips e-LED ayishumi nambili noma ngaphezulu, ngokuvamile axhumeke ndawonye.Ukukhanya okukhanyayo kwe-chip ngayinye kunqunywa ubukhulu bamanje obudlula kuyo.Njengomphumela wokuxhuma kochungechunge, i-chip ngayinye ye-LED ngaphakathi kwe-LED izodlula ngokuzenzakalelayo ku-current efanayo, kodwa i-voltage ku-chip ngayinye ihlukile.Ukwehla kwamandla kagesi aya phambili kwe-LED ngokuvamile kungu-3.4V, kodwa kuyehluka phakathi kuka-2.8V no-4.2V.I-LED ingahlukaniswa ukuze kukhawulwe uhla lokuguquguquka kwamandla kagesi, kodwa lokhu kuzonyusa izindleko, futhi ukwehla kwamandla kagesi okuya phambili kusazoshintsha ngezinga lokushisa nokusetshenziswa kwesikhathi.Ukuze unikeze ukukhanya okuphumayo okungaguquki, i-LED kufanele ishayelwe igagasi elingaguquki elisebenza kahle kakhulu elilawulwa ngokuqinile.Njengenye indlela yezibani ze-incandescent ze-LED, ukunikezwa kwamandla kufanele kuhlanganiswe ezindlini zesibani.
2: Okujwayelekile okuhlanganisiwe kwe-LED Electronic Sirens kanye nezipikha kuhlanganisa i-drive circuit, i-LED cluster futhi ingahlinzeka ngomshayeli ne-chip ye-LED yokuvikela ngomshini nokupholisa kwegobolondo.
3: Izidingo zomshayeli we-LED ziqinile kakhulu.Kufanele yonge amandla futhi kufanele ihlangabezane nezicaciso eziqinile ze-EMI kanye nesici samandla futhi ingamelana ngokuphephile nezimo zamaphutha ahlukahlukene.Enye yezidingo ezinzima kakhulu ukuba nomsebenzi wokufiphalisa.Ngenxa yokungaguquguquki phakathi kwezimpawu zesibani se-LED nesilawuli sokufiphala esidizayinelwe izibani ze-incandescent, kungenzeka kubangele ukusebenza kabi.Inkinga ingase ibe ukuthi ijubane lokuqalisa lihamba kancane, liyacwayiza, ukukhanya kwe-Electronic Sirens nezipikha kungalingani, noma ukucwayiza lapho ukukhanya kulungiswa.Ngaphezu kwalokho, kukhona ukungqubuzana ekusebenzeni kweyunithi ngayinye kanye nezibani ze-LED ezikhishwe umsindo ozwakalayo nezinye izinkinga.Lezi zimo ezingezinhle ngokuvamile zibangelwa ukucupha okungamanga noma ukuvala shaqa ngaphambi kwesikhathi kwesilawuli nokulawula okungalungile kwe-LED yamanje nezinye izici.
4: Okwamanje, imikhiqizo ye-LED ithi inegebe elikhulu nempilo yesevisi yangempela.Esimeni sokuqoqwa okulinganiselwe kobuchwepheshe bomklamo wesekethe yedrayivu, nokuhlolwa kwempilo yomkhiqizo ukuze kulinganiswe impilo yangempela yendlela, okungenzeka kubangele amaphutha.Nakuba ukuzinza komugqa wokushayela kuzothinta ngokuqondile ukuzinza okuphelele komkhiqizo.
