Ma LED emwenje mitsetse anogona kutemwa here?
Inogona kutemwa. Dunhu re LED mwenje strip rakagadzirwa kuburikidza neakateedzana / parallel yekubatanidza, asi iyo mitemo yekuti ingachekwa sei yakasiyana. Izvi zvinoenderana nekugadzirwa kweiyo LED mwenje strip. Kazhinji, vagadziri ve LED mwenje mitsetse vari kugadzira mwenje we LED. Kana zvasvika kune mitsetse, vane mitemo yedunhu rekugadzirisa LED mitsetse zvinoenderana nezvinodiwa. Mabheji emwenje e LED anoshandiswawo zvinoenderana nezvinodiwa. Mabheji emwenje e LED ane akasiyana ekushanda voltage miganho, saka mwenje we LED mitsetse yakavakirwa pamagetsi emarambi anoshandiswa. Yakasiyana, nzvimbo yekucheka ichavawo yakasiyana.
Muenzaniso 1: 12-volt LED mwenje mitsetse inowanzouya mune maviri zvirevo, ine mwenje imwe chete uye imwe yakachekwa, kana mwenje mitatu uye imwe yakachekwa.
- Chokutanga pane zvose, tichazivisa imwe-rambi imwe-yekucheka nzira. Inoshandisa 9-volt inoshanda voltage rambi bead. Nenzira iyi, 9-volt rambi bead uye resistor inogona kubatanidzwa munhevedzano kuderedza voltage, uye imwe mwenje-imwe yekucheka inogona kuwanikwa.
- Ndiko kucheka marambi matatu kamwechete. Anoshandisa matatu matatu-volt marambi mabhero. Aya marambi matatu akabatanidzwa munhevedzano ane resistor kuderedza voltage, kuitira kuti mwenje mitatu inogona kutemwa pane imwe nzvimbo.
Muenzaniso wechipiri: Pane zvakawanda zvakatemwa zve 24-volt LED mwenje mitsetse. Izvo zvinzvimbo uko 24-volt LED mwenje mitsetse inogona kutemwa pamusika inogona kukushamisa iwe. 24-volt LED chiedza mitsetse inosanganisira imwe-rambi-imwe-yakatemwa, maviri-mwenje-imwe-yakatemwa, uye matatu-mwenje-imwe-yakatemwa. Cheka, mwenje mitanhatu uye imwe kucheka, uye marambi manomwe uye imwe yakachekwa. Pasina imwe nguva, regai ndizvizivise kumunhu wese kutanga.
- Imwe-yekucheka kushanda kwemwenje mumwe chete. Inoshandisa 18V kusvika 21V inoshanda voltage rambi mabedhi uye resistors akabatana munhevedzano kudzikisa voltage. Izvi zvinogona kuwana rimwe-rambi rimwe-off operation.
- Maitiro ekugadzira mwenje maviri uye imwe yakachekwa ye LED mwenje strip? Anoshandisa maviri 9-volt kushanda voltage rambi mabhero uye resistors akabatana munhevedzano kuderedza voltage, kuitira kuti mwenje-maviri uye imwe-yakatemwa dhizaini inogona kuwanikwa.
- Maitiro ekugadzira mwenje matatu uye imwe yakachekwa ye LED mwenje strip? Anoshandisa mabheji matatu emwenje ane simba rekushanda re6 volts uye anoabatanidza munhevedzano nevanopikisa kuti vaderedze voltage, kuitira kuti matatu-marambi-imwe-yakatemwa dhizaini inogona kuwanikwa.
- Iyo nhanhatu-mwenje-imwe-yakacheka LED mwenje tambo inoshandisa matanhatu 3-volt marambi mabhero. Iwo matanhatu marambi mabhedhi uye resistors akabatanidzwa munhevedzano kuderedza voltage, kuitira kuti matatu-marambi imwe-yakatemwa dhizaini inogona kuwanikwa.
- Zvakadini neiyo ine marambi manomwe uye imwe yakachekwa? Iyo minomwe-mwenje-imwe-yakatemwa LED mwenje strip ine manomwe 3-volt mwenje mabheji uye resistors akabatana munhevedzano, kuitira kuti mwenje minomwe imwe-yakatemwa dhizaini inogona kuwanikwa.
Muchokwadi, iwo ma LED mwenje mitsetse ichaiswa mucherechedzo pakutanga kwedhizaini. Tambo imwe neimwe yemwenje inenge iine mutsara wakatwasuka kwaunokwanisa kutemwa. Iwe unongoda kuicheka panzvimbo iyi. Kana nzvimbo yekucheka isiri pamutsara wakatwasuka, ichaita kuti seti yemarambi e LED itemwe. Hapana chiedza.
Pazasi ini ndichakuratidza mamwe mafoto ezvigadzirwa zvekambani yedu kuti ikubatsire kuona nzvimbo dzekucheka dze LED mwenje mitsetse.
Chengetedzo yekucheka
- Paunenge uchicheka LED mwenje mitsetse, ndapota cherechedza kuti inofanirwa kutemwa yakatwasuka.
- Teerera kune akasiyana akachekwa e LED mwenje strip mahwendefa. Kuti usangane neiyo yekupisa conductivity uye kupisa kupisa kuita kwe LED mwenje mitsetse, mazhinji e LED mwenje mitsetse ikozvino anonyanya kushandisa aluminium substrates. Aluminium substrates inofambisa. Paunenge uchiveura, Zvinonyanya kukonzera kupfupika kwedunhu, saka isu tinofanirwa kutarisa kana foil yemhangura yakabatana nealuminium substrate pazasi mushure mekucheka. Kana zvinongedzo zvakabatana, tinofanirwa kuzviparadzanisa kuti tivheneke mwenje we LED.
Tekinoroji yeLED yakashandura nzira yatinovhenekera nayo dzimba dzedu nemabhizinesi. Haisi kungounza kushandiswa kwesimba kune chiedza, inovandudzawo kunaka kwechiedza, zvichiita kuti zvigadziriswe kune zvakasiyana-siyana zvekugadzirisa. LED inomirira light-emitting diode, semiconductor mudziyo unoburitsa chiedza kana magetsi achipfuura napo. Tekinoroji ye LED inoshanda zvakanyanya kupfuura yechinyakare incandescent uye mwenje wefluorescent. Asi ma LED anoshanda sei?
Chimwe chezviratidzo zvakakosha zvekuvhenekera kwemwenje ndiko kushandiswa kwesimba. Tekinoroji ye LED inozivikanwa nekushomeka kwesimba rekushandisa, zvichiita kuti ive sarudzo yakakurumbira yekuvhenekesa kwekugara uye kwekutengesa. Asi magirobhu eLED anochengetedza simba rinosvika 80% kupfuura echinyakare incandescent bulbs uye inosvika 20-30% kupfuura magirobhu efluorescent. Kudzikiswa kwekushandiswa kwesimba hakungodzikisi mabhiri emagetsi evatengi chete asiwo kunobatsira zvakanyanya kuderedza kuburitswa kwekabhoni, zvichiita kuti tekinoroji yeLED ive sarudzo ine hushamwari hwekuvhenekesa.
Zvese mune zvese, tekinoroji ye LED inoshanda zvakanyanya maererano nekushandiswa kwesimba, hupenyu hurefu, kubuda kwechiedza uye kudzoreka. Simba rayo rakaderera kushandisa, hupenyu hurefu, kubuda kwechiedza chepamusoro uye kushanda-pakarepo kunoita kuti ive sarudzo yakanakisa yekuvhenekesa kana ichienzaniswa neyekare incandescent uye mwenje wefluorescent. Sezvo kudiwa kwemagetsi ekuchengetedza uye ane hushamwari mwenje mhinduro kuri kuramba kuchikura, tekinoroji yeLED inotarisirwa kuita basa rinowedzera kukosha mukuumba ramangwana remwenje.
