Izindaba

Izibani ze-LED ezingenathunzi, njengesibani esisetshenziswa kakhulu esingenamthunzi, zinezici ze-spectrum emincane, umbala wokukhanya omsulwa, amandla aphezulu okukhanya, ukusetshenziswa kwamandla okuphansi, nokuphila kwesevisi ende, okuphakeme kunemithombo yokukhanya ye-halogen evamile. Uma kuqhathaniswa namalambu okuhlinzwa e-halogen endabuko angenathunzi, amalambu angenathunzi e-LED axazulula ububi bamandla aphansi, ukunikezwa kombala okungekuhle, ububanzi bendawo okugxilwe kuyo encane, izinga lokushisa eliphezulu, nempilo emfushane yesevisi yezibani zendabuko ezingenathunzi. Ngakho-ke, yini umsebenzi wezibani ze-LED ezingenathunzi?
Ukukhanya okungenathunzi kwe-LED kuyithuluzi lezokwelapha elibalulekile emnyangweni wokuhlinza. Phakathi nenqubo yokuhlinzwa, akudingekile kuphela ukuba "ungabi nesithunzi", kodwa futhi ukhethe ukukhanya ngokukhanya okuhle, okungahlukanisa kahle umehluko wombala phakathi kwegazi nezinye izakhiwo nezitho zomzimba womuntu. Ukuhlaziywa okusebenzayo kwezibani ze-LED ezingenathunzi:

1. Umthombo wokukhanya we-LED oqinile. Uchungechunge lwe-ZW isibani esingenasithunzi sisebenzisa ubuchwepheshe bokukhanyisa obuluhlaza futhi obusetshenziswa kancane, obunempilo ye-bulb efinyelela emahoreni angu-50000, okuphindwe izikhathi eziningi kunezibani ezingenathunzi ze-halogen. Ukusetshenziswa kohlobo olusha lomthombo wokukhanya obandayo we-LED njengokukhanyisa okuhlinzayo kuwumthombo wangempela wokukhanya obandayo, cishe akukho ukushisa okwandayo ekhanda likadokotela nendawo yenxeba.
2. Umklamo omuhle kakhulu we-optical. Ukusebenzisa isofthiwe yekhompyutha kusiza ukuklama ubuchwepheshe ukulawula i-engeli yokufaka enezinhlangothi ezintathu yelensi ngayinye, okwenza indawo yokukhanya ibe yindilinga kakhudlwana; Ilensi esebenza kahle kakhulu kuma-engeli amancane iphumela ekusebenzeni kahle kokukhanya okuphezulu nokukhanya okugxiliswe kakhudlwana.
3. Idizayini yesakhiwo eyingqayizivele yezingxenye zomthombo wokukhanya. Ibhodi lomthombo wokukhanya lenziwe nge-substrate ye-aluminium ebalulekile, enciphisa inani elikhulu lezintambo ezindizayo, yenza isakhiwo sibe lula, iqinisekise ikhwalithi ezinzile, ithuthukise ukuchithwa kokushisa, futhi ibe nempilo ende yesevisi.
4. Ukulawula indawo efanayo. Idivayisi yokugxila emaphakathi ingafinyelela ukulungiswa okufanayo kobubanzi bendawo.
5. Kulula ukusebenzisa izinga lokushisa lombala kanye nemisebenzi yezinga lokukhanya. Ukufiphala kwe-PWM okungenazinyathelo, isixhumi esibonakalayo esilula nesicacile sokusebenza kwesistimu, idizayini eguquguqukayo enezinga lokushisa elishintshayo lombala.
6. Isistimu yekhamera yencazelo ephezulu. Ngokwamukela ubuchwepheshe be-high-frequency pulse wide dimming, isistimu yekhamera ephakathi/yangaphandle enencazelo ephezulu ingalungiselelwa ukuxazulula inkinga yokucwayiza kwesikrini ohlelweni lwekhamera.
7. Ukulawula ukuthinta, isinxephezelo sethunzi, neminye imisebenzi ihlinzeka abasebenzi bezokwelapha ngokuhlinzwa okulula kakhudlwana.

Izinyathelo zokuphepha
Ngokucabangela izidingo ezikhethekile zokuphepha zemishini yezokwelapha, izinyathelo zokuphepha ezihambisanayo kufanele zithathwe kuzo zonke izigaba zohlelo. Okokuqala, igumbi lokuhlinza liyindawo eqinile, futhi kubaluleke kakhulu ukuvimbela i-microcontroller ekushayeni, ngakho-ke izinyathelo ezilandelayo kufanele zithathwe.
(1) Idizayini yezingxenyekazi zekhompyutha kanye nezinqubo zokusetha kabusha kwangaphakathi kufanele kusingathwe ngokuqapha;
(2) Izimpawu zokuphazanyiswa okungamanga kufanele zisuswe, ngakho lonke uhlelo lwamukela ukuhlukaniswa okuphelele kukagesi ukuze kuvinjelwe ukuphazanyiswa phakathi kwezingxenye ezihlukahlukene zesekethe. Ngaphezu kwalokho, indlela yokuhlola i-Modbus redundancy nayo yamukelwa.
(3) Ukukhanya okuphezulu kwe-LED emhlophe inenani eliphezulu. Ukuze ugweme umonakalo, kuyadingeka ukuqeda umthelela wegridi yamandla kanye nokulimala ohlelweni. Ngakho-ke, i-overvoltage kanye ne-overcurrent yokuvikela okuzenzakalelayo kwesekethe yamukelwa. Uma i-voltage noma i-current idlula u-20% yenani elimisiwe, isistimu inqamula ngokuzenzakalelayo amandla ukuze kuqinisekiswe ukuphepha kwesekethe yesistimu kanye nokukhanya okuphezulu kwe-LED.
