Inkcazo esisiseko ye-LED Driver Power Supply
Ubonelelo lombane sisixhobo okanye isixhobo esiguqula amandla ombane asisiseko ngobuchule bokuguqula ube ngamandla ombane wesibini afunwa zizixhobo zombane.Amandla ombane esiqhele ukuwasebenzisa kubomi bethu bemihla ngemihla asuka ikakhulu kumandla oomatshini aguqulwayo, amandla ashushu, amandla ekhemikhali, njl.Ngokwesiqhelo, amandla ombane asisiseko awafikeleli kwiimfuno zomsebenzisi.Apha kulapho unikezelo lwamandla luqala khona ukudlala, ukuguqula amandla ombane asisiseko ukuya kumandla ombane akwisibini afunekayo.
Inkcazo: Umbane womqhubi we-LED luhlobo lwamandla ombane oguqula amandla ombane aphambili ukusuka kwimithombo yangaphandle ukuya kumandla ombane wesibini afunwa yi-LEDs.Yiyunithi yobonelelo lwamandla eguqula unikezelo lwamandla kwivoltheji ethile kunye neyangoku ukuqhubela ukukhutshwa kokukhanya kwe-LED.Igalelo lamandla ombane womqhubi we-LED liquka zombini i-AC kunye ne-DC, ngelixa amandla aphumayo ngokubanzi agcina i-current eqhubekayo enokuthi itshintshe i-voltage kunye notshintsho kwi-voltage ye-LED eya phambili.Amacandelo ayo aphambili abandakanya izixhobo zokucoca igalelo, abalawuli bokutshintsha, i-inductors, iishubhu zokutshintsha i-MOS, i-resistors yempendulo, izixhobo zokucoca imveliso, njl.
Iindidi ezahlukeneyo zobonelelo lwaMandla oMqhubi we-LED
Izixhobo zombane zomqhubi we-LED zinokuhlelwa ngeendlela ezahlukeneyo.Ngokuqhelekileyo, zinokwahlulwa zibe ziindidi ezintathu eziphambili: tshintsha imithombo yangoku engaguqukiyo, unikezelo lwamandla lwe-IC oluhambelanayo, kunye nokubonelela ngokunciphisa amandla okunciphisa amandla.Ngaphezu koko, ngokusekwe kumazinga ombane, izixhobo zombane zomqhubi we-LED zinokuphinda zihlele ngokwamandla aphezulu, amandla aphakathi, kunye nezixhobo zomqhubi wamandla aphantsi.Ngokubhekiselele kwiindlela zokuqhuba, izixhobo zombane zomqhubi we-LED zinokuba ziintlobo zangoku zangoku okanye rhoqo.Ngokusekelwe kwisakhiwo sesekethe, izixhobo zombane zomqhubi we-LED zingahlelwa njengokunciphisa amandla, ukunciphisa i-transformer, ukunciphisa ukuchasana, ukunciphisa i-RCC, kunye neentlobo zokulawula i-PWM.
Ubonelelo lwaMandla oMqhubi we-LED-Icandelo eliPhambili lokuLungisa ukuKhanya
Njengenxalenye eyimfuneko kwizibane ze-LED, umbane womqhubi we-LED uthatha i-20% -40% yeendleko zokulungiswa kwe-LED zizonke, ngakumbi kwiimveliso zokukhanyisa ze-LED eziphakathi ukuya kumandla aphezulu.Izibane ze-LED zisebenzisa iitshiphusi ze-semiconductor njengezinto ezikhupha ukukhanya kwaye zineenzuzo ezifana nokusebenza kakuhle kwamandla, ubuhlobo bendalo, ukunikezelwa kombala okulungileyo, kunye nexesha lokuphendula ngokukhawuleza.Njengohlobo oluqhelekileyo olusetyenziswayo lokukhanyisa kuluntu lwanamhlanje, iinkqubo zokuvelisa izibane ze-LED zibandakanya amanyathelo angundoqo ayi-13, kubandakanywa ukusika ucingo, ukuthengiswa kwee-chips ze-LED, ukwenza iibhodi zezibane, iibhodi zezibane zokuvavanya, ukusebenzisa i-silicone conductive thermal, njl. imigangatho yomgangatho engqongqo.
Impembelelo enzulu ye-LED Driver Power Supplies kwi-Industry Lighting ye-LED
Izixhobo zombane zomqhubi we-LED zidibanisa kunye nemithombo yokukhanya ye-LED kunye nezindlu ukuze zenze iimveliso zokukhanyisa i-LED, zisebenza njengezona zinto ziphambili.Ngokuqhelekileyo, isibane ngasinye se-LED sidinga umbane ohambelana nomqhubi we-LED.Umsebenzi ophambili wobonelelo lwamandla omqhubi we-LED kukuguqula unikezelo lwamandla lwangaphandle kwi-voltage ethile kunye nekhoyo ngoku ukuqhuba iimveliso zokukhanya kwe-LED zokukhanyisa kunye nolawulo oluhambelanayo.Badlala indima ebalulekileyo ekwandiseni ukusebenza kakuhle, ukuzinza, ukuthembeka, kunye nobomi beemveliso zokukhanyisa ze-LED, okunefuthe elimandla ekusebenzeni kwazo kunye nomgangatho.Ngokwezibalo ezivela kuninzi lwabavelisi bezibane zesitalato, phantse i-90% yokusilela kwizibane ze-LED zezitrato kunye nezibane zetonela zibalelwa kwiimpazamo zobonelelo lwamandla omqhubi kunye nokungathembeki.Ke, unikezelo lwamandla omqhubi we-LED lwenza enye yezinto ezibalulekileyo eziphembelela uphuhliso lweshishini lokukhanyisa i-LED.
Izibane ze-LED zilungelelaniswa ngokunzulu kunye neNdlela yoPhuhliso loHlaza
Ii-LED ziqhayisa ukusebenza okubalaseleyo, kwaye amathemba azo exesha elide anethemba.Kwiminyaka yakutshanje, njengoko imeko yemozulu yehlabathi isanda, ulwazi lokusingqongileyo lukhula.Uqoqosho lwekhabhoni ephantsi lube yimvumelwano yophuhliso loluntu.Kwicandelo lokukhanyisa, amazwe kwihlabathi jikelele ahlola ngokusebenzayo iimveliso kunye neendlela zokuphumeza ukugcinwa kwamandla kunye nokunciphisa ukukhutshwa.Xa kuthelekiswa neminye imithombo yokukhanya efana ne-incandescent kunye ne-halogen bulbs, izibane ze-LED zingumthombo wokukhanya okuluhlaza kunye neenzuzo ezifana nokusebenza kakuhle kwamandla, ubuhlobo bendalo, ubomi obude, ukuphendula ngokukhawuleza, kunye nokucoceka kombala ophezulu.Ekuhambeni kwexesha, izibane ze-LED zihambelana nzulu kunye nexesha lexesha lophuhliso lohlaza kunye nengcamango yophuhliso oluzinzileyo, olulungele ukukhusela indawo ehlala ixesha elide kwimarike yokukhanyisa okunempilo kunye nohlaza.
Ukuqaliswa kweMigaqo-nkqubo yoShishino eKhonzelisa uPhuhliso lweXesha elide loShishino lwaBaqhubi
Ngemigaqo-nkqubo eqinisa icandelo, ukutshintshwa kwezibane ze-LED kunethuba.Ngenxa yokusebenza kwayo okuphezulu kunye neempawu zokonga amandla, ukukhanya kwe-LED kusebenza njengenye indlela egqwesileyo kwimithombo yemveli ephezulu edla amandla.Ngokuchasene nemvelaphi yemicimbi ekhulayo yokusingqongileyo, amazwe kwihlabathi jikelele agxininisa ngakumbi kugcino lwamandla kunye nokunciphisa ukukhutshwa, ngokuqhubekayo ekhulula imigaqo-nkqubo ehambelana nokukhanya okuluhlaza.Ishishini le-LED liye laba lelinye lamashishini asakhulayo anobuchule kwilizwe lethu.Ubonelelo lwamandla omqhubi we-LED kulindeleke ukuba luxhamle kakhulu kwinkxaso yomgaqo-nkqubo, lungenise isigaba esitsha sokukhula.Ukukhutshwa kwemigaqo-nkqubo yoshishino kunika isiqinisekiso sophuhliso lwexesha elide lonikezelo lwamandla omqhubi we-LED.
