LED Common Malfunctions uye Solutions
Mwenje ye LED zvishoma nezvishoma inotora musika wemazuva ano wemarambi emagetsi nekuda kwekupenya kwavo kwakanyanya, kuderera kwesimba rekushandisa uye hupenyu hurefu. Kazhinji, zviedza zve LED zvakaoma kuputswa. Mumagetsi e LED, pane matambudziko matatu anowanzo: magetsi haana kujeka, magetsi anodzima, uye magetsi ari kupenya mushure mekudzima. Nhasi tichaongorora dambudziko rimwe nerimwe.
LED chiedza chimiro
Mwenje ye LED ine mafomu akawanda. Pasinei nerudzi rwemwenje, chimiro chemukati chakafanana, chakakamurwa kuva bhedhi remwenje uye mutyairi.
Marambi mabhesi
Vhura iyo yekunze casing yemwenje we LED kana iyo chena yepurasitiki chikamu chegirobhu. Iwe unogona kuona kuti pane bhodhi redunhu rakafukidzwa nerectangle yero mukati. Iyo yero ruvara zvinhu pabhodhi iri ibhedhi remwenje. Chiedza chemwenje ndicho chinovhenekera mwenje we LED, uye nhamba yacho inosarudza kupenya kwemwenje we LED.
Mutyairi kana magetsi emwenje ye LED akaiswa pasi uye haaoneki kubva kunze.
Mutyairi anogara aripo, nhanho-pasi, kugadzirisa, kusefa uye mamwe mabasa.
Mhinduro yekugadzirisa dambudziko kana chiedza che LED chisina kujeka zvakakwana.
Kana mwenje wadzimwa, unofanira kutanga waona kuti dunhu rakanaka. Kana chiri chiedza chitsva, shandisa chinyoreso chemagetsi kuyera, kana kuisa mwenje weincandescent kuti uone kana pane voltage munharaunda. Mushure mekusimbisa kuti dunhu rakanaka, unogona kutanga kunotevera kugadzirisa dambudziko.
Mutyairi kana dambudziko rekupa magetsi
Magetsi haana kuvheneka, uye dambudziko rinokonzerwa nemutyairi. Chiedza-emitting diodes ane zvinodiwa zvakanyanya pane zvazvino uye voltage. Kana iyo yazvino uye voltage zvakakurisa kana zvidiki, hazvigone kuvhenekerwa. Naizvozvo, madhiraivha anogara aripo, anogadziridza, uye mari mutyairi anodiwa kuchengetedza kushandiswa kwavo.
Kana mwenje usina kuvhenekerwa mushure mekubatidza mwenje, isu tinofanira kutanga tafunga nezve dambudziko remutyairi kana magetsi. Kana ikatariswa kuti idambudziko remagetsi, unogona kutsiva zvakananga magetsi matsva.
Mhinduro ye LED mwenje kupenya kusviba
Dambudziko iri rinofanira kugadziriswa pamwe chete nemubvunzo wapfuura. Izvi zvinogona kunge zvakadaro kana kupenya kwechiedza kwakadzikira kana kusavhenekwa.
Dambudziko remarambi
Iwo ma LED mabhedhi emamwe marambi e LED akabatanidzwa munhevedzano. Mabhero patambo imwe neimwe akabatanidzwa munhevedzano; uye tambo dzakabatanidzwa mukufanana.
Naizvozvo, kana bhero remwenje rikapisa patambo iyi, zvinoita kuti tambo yemwenje idzime. Kana tambo imwe neimwe ikapfuta bhera, mwenje wose unobva wadzima. Kana pane bhiza rakatsva mutambo imwe neimwe, funga nezve capacitor kana resistor dambudziko pamutyairi.
Bhiza remwenje wakatsva uye bhero remwenje rinowanzoonekwa kubva pakuonekwa. Bhanga rerambi rakatsva rine doti dema pakati, uye dot harigone kudzimwa.
Kana huwandu hwemarambi akatsva hudiki, tsoka mbiri dzekubatirira dziri seri kwebhero remwenje unogona kutengeswa pamwe chete nesimbi yekunyungudika. Kana nhamba yemarambi yakatsva yakawandisa, zvinokurudzirwa kutenga bheji remwenje kuti uitsive, kuitira kuti irege kukanganisa kupenya kwechiedza.
Solution yekubwaira mushure mekunge LED yadzimwa
Paunoona kuti dambudziko rekupenya rinoitika mushure mekunge rambi radzimwa, simbisa dambudziko remutsara kutanga. Dambudziko rinonyanya kuitika ndeye zero mutsara weiyo switch control. Muchiitiko ichi, zvinodikanwa kuigadzirisa munguva kuti udzivise ngozi. Nzira chaiyo ndeyekuchinja mutsara wekutonga uye mutsara usina kwawakarerekera.
Kana pasina dambudziko nedunhu, zvinogoneka kuti mwenje we LED unoburitsa wega-inductive ikozvino. Nzira iri nyore ndeyekutenga 220V relay uye batanidza coil kune rambi munhevedzano.
