IUkunikezelwa kwamandla okuqhuba i-LEDuguqula unikezelo lwamandla kwi-voltage ethile kunye nekhoyo ngoku ukuqhuba isiguquli sombane we-LED.Ngesiqhelo: igalelo leUkunikezelwa kwamandla okuqhuba i-LEDiquka i-high-voltage frequency frequency AC, low-voltage DC, high-voltage DC, low-voltage high-frequency AC, njl. Ngoko ke namhlanje ndiza kukubonisa unikezelo lwamandla ombane rhoqo LED.
Unikezelo lwamandla ombane rhoqoindlela yokuqhuba
Unikezelo lwamandla ombane rhoqo
1. Emva kokuba i-voltage stabilizing circuit inquma iiparameters ezahlukeneyo, ikhupha i-voltage engatshintshiyo, kodwa umphumo wangoku utshintsha ngokunyuka okanye ukuncipha komthwalo.
2. Nangona i-voltage stabilizing circuit ingoyiki ukuvuleka komthwalo, inqatshelwe ngokungqongqo ukuba ifutshane-mfutshane umthwalo.
3. Ukutshintsha kombane emva kokulungiswa kuya kuchaphazela ukukhanya kwe-LED.
4. Ukwenza umtya ngamnye wee-LED eziqhutywa yi-voltage stabilizing circuit ubonisa ukukhanya okufanayo, i-resistor efanelekileyo kufuneka ifakwe.
5. Isekethe yokuqhuba i-voltage eqhubekayo ilungele ngakumbi ukuqhuba i-LED, kwaye i-voltage eqhubekayo yindlela yexesha elizayo.
Iimpawu zeunikezelo lwamandla ombane rhoqo
(1) Ukuthembeka okuphezulu
Ngokukodwa njengombane wokuqhuba izibane zesitrato ze-LED, zifakwe kwindawo ephakamileyo, okwenza ukugcinwa kungabi lula kwaye kubize.
(2) Ukusebenza okuphezulu

Ukusebenza kwamandla ale ndlela yokubonelela ngombane kuphantsi kakhulu, kwaye ukuthembeka kwenkqubo kuphantsi.Ngenxa yokuba isiphaluka sinciphisa i-voltage ngokusebenzisa i-resistors, iphazamiseka kakhulu ngotshintsho kwi-voltage yegridi, ngoko akulula ukwenza unikezelo lwamandla olulawulwayo, kwaye i-resistor yokunciphisa i-voltage ngokwayo idla inxalenye enkulu yamandla.
5. I-RCC inyathelo lokuya phantsi unikezelo lombane lokutshintsha:
Iingenelo zolu hlobo lonikezelo lwamandla ombane we-LED luluhlu olubanzi lokuzinzisa amandla ombane kunye nokusebenza kakuhle kwamandla aphezulu, anokuba ngama-70% ukuya kuma-80%, kwaye asetyenziswa ngokubanzi.Izinto ezingalunganga eziphambili kukuba kunzima ukulawula ukuphindaphinda, umthamo we-voltage ripple coefficient mkhulu, kwaye ukulungelelaniswa komthwalo kubi phantsi kweemeko ezingaqhelekanga.
6. Unikezelo lombane lokutshintsha olulawulwa yiPWM:
Okwangoku, izixhobo zombane ze-LED eziyilwe ngolawulo lwe-PWM zifanelekile kuba i-voltage ephumayo okanye yangoku yale ntambo yombane yokutshintsha izinzile kakhulu.Ukusebenza koguqulo lwamandla kuphezulu kakhulu, ngokubanzi ukuya kuthi ga kwi-80% ~ 90%, kwaye amandla ombane aphumayo kunye nangoku azinzile kakhulu.Le ndlela yonikezelo lwamandla e-LED ubukhulu becala iqulathe iinxalenye ezine: ukulungiswa kwegalelo kunye nenxalenye yokucoca, ukulungiswa kwemveliso kunye nenxalenye yokucoca, inxalenye yolawulo lozinzo lombane we-PWM, kunye nokuguqula inxalenye yokuguqula amandla.Ngaphezu koko, le sekethi inemilinganiselo yokukhusela epheleleyo kunye nokunikezelwa kwamandla okuthembekileyo.
Iimfuno zeempawu zokusebenza ezisibhozo zeunikezelo lwamandla ombane rhoqo
Ngokwemigaqo yokusetyenziswa kwamandla egridi yamandla kunye neemfuno zeempawu zobonelelo lwamandla ombane we-LED, ezi mpawu zilandelayo zisithoba kufuneka zithathelwe ingqalelo xa kukhethwa kwaye kuyilwa unikezelo lwamandla ombane we-LED:
1. Ukuthembeka okuphezulu, ngokukodwa umbane wokuqhuba izibane zesitrato ze-LED, ezifakwe kwindawo ephakamileyo, okwenza ukugcinwa kungabi lula kwaye kuyabiza.
2. Ii-LED eziphezulu eziphezulu ziyimveliso yokugcina amandla, kwaye ukusebenza kakuhle kokunikezelwa kwamandla okuqhuba kufuneka kube phezulu.Oku kubaluleke kakhulu kwizakhiwo apho ukunikezelwa kwamandla kufakwe ngaphakathi kwesibane.Ngenxa yokuba ukusebenza okukhanyayo kwee-LED kuncipha njengoko ubushushu be-LED busanda, ukuchithwa kobushushu kwe-LED kubaluleke kakhulu.Ukusebenza kokunikezelwa kwamandla kuphezulu, ukusetyenziswa kwayo kwamandla kuncinci, kwaye ukushisa okwenziwa kwisibane kuncinci, okunciphisa ukunyuka kweqondo lokushisa kwesibane.Kuyinzuzo ukulibazisa ukubola kokukhanya kwe-LED.
3.Umba wamandla aphezulu Amandla ayimfuneko yimfuno yegridi yomthwalo.Ngokubanzi, akukho zikhombisi ezinyanzelekileyo zezixhobo zombane ezingaphantsi kwe-70 watts.Nangona umbane ophantsi wesixhobo sombane esinye esinamandla amancinci uya kuba neempembelelo ezincinci kwigridi yamandla, ukuba wonke umntu ulayita izibane ebusuku kwaye uhlobo olufanayo lomthwalo lugxile kakhulu, luya kubangela ungcoliseko olukhulu kwigridi yamandla.Kwi-30- ukuya kwi-40-watt ye-LED yokuhambisa amandla ombane, kuthiwa kunokubakho iimfuno ezithile zesalathiso kwizinto zamandla kwixesha elizayo elikufutshane.
4.Ukukhuselwa kwe-surgery amandla e-LED okumelana nokunyuka kumbi kakhulu, ngakumbi amandla ayo okumelana nombane obuyela umva.Ukomeleza ukhuseleko kule ndawo nako kubalulekile.Ezinye izibane ze-LED zifakwe ngaphandle, njengezibane zesitrato ze-LED.Ngenxa yokusebenza komthwalo wegridi kunye nokungeniswa kombane, ukunyuka okuhlukahlukeneyo kuya kuhlasela kwi-system yegridi, kwaye ezinye iinqwelo ziza kubangela umonakalo kwi-LED.Ke ngoko, unikezelo lwamandla okuqhuba i-LED kufuneka lube namandla okucinezela ukungena kwe-surgery kunye nokukhusela i-LED kumonakalo.
5. Umsebenzi wokukhusela Ukongeza kwimisebenzi yokukhusela eqhelekileyo yonikezelo lwamandla, kungcono ukongeza ubushushu be-LED impendulo engalunganga kwimveliso eqhubekayo yangoku ukukhusela ubushushu be-LED ukuba bube phezulu kakhulu.
6. Ngokwemiqathango yokukhusela, ukuba isibane sifakwe ngaphandle, isakhiwo sokunikezelwa kwamandla kufuneka singabi namanzi kunye nobungqina bomswakama, kwaye i-casing yangaphandle kufuneka ibe nokukhanya.
7. Ubomi bokunikezelwa kwamandla okuqhuba kufuneka buhambelane nobomi be-LED.
8. Kufuneka ihambelane nemigaqo yokhuseleko kunye neemfuno zokuhambelana kwe-electromagnetic.
Njengoko ukusetyenziswa kwe-LED kuya kusasazeka ngakumbi, ukusebenza kombane wokuqhuba i-LED kuya kuba ngakumbi nangakumbi ngokufanelekileyo kwiimfuno ze-LED.
