Munguva yakapfuura, marambi ehalogen aiwanzosarudzwa kuti avheneke motokari.Mumakore achangopfuura, kushandiswa kwe LED mumotokari yose kwakatanga kukura nokukurumidza.Hupenyu hwesevhisi hwemarambi ehalogen echinyakare hungori maawa mazana mashanu, nepo iwo eiyo mainstream LED marambi emusoro anosvika 25000 maawa.Iko mukana wehupenyu hurefu hunenge huchitendera marambi e LED kuvhara hupenyu hwese hwemotokari.
Kushandiswa kwemarambi ekunze uye emukati, senge remberi yekuvhenekesa mwenje, mwenje wechiratidzo chekutendeuka, mwenje wemuswe, mwenje wemukati, nezvimwewo, wakatanga kushandisa LED sosi yekugadzira uye kusanganisa.Kwete chete mota dzekuvhenekesa masisitimu, asiwo ekuvhenekesa masisitimu kubva kumagetsi evatengi kuenda kufekitori otomatiki michina.Magadzirirwo e LED mune aya masisitimu ekuvhenekesa ari kuwedzera kusiyanisa uye akabatanidzwa zvakanyanya, ayo anonyanya kuzivikanwa mumagetsi emagetsi masisitimu.
Kukura nekukurumidza kwe LED mumotokari yekuvhenekesa system
Sesosi yekuvhenekesa, LED haingove nehupenyu hurefu chete, asi kushanda kwayo kupenya kunodarikawo mwenje wakajairwa halogen.Kupenya kwemarambi ehalogen ndiko 10-20 Im/W, uye kupenya kwe LED ndeye 70-150 Im/W.Kuenzaniswa neyakakanganiswa kupisa kupisa sisitimu yemarambi echinyakare, kuvandudzwa kwesimba rinopenya richava rekuchengetedza simba uye rinoshanda mukuvhenekesa.Iyo LED nanosecond yekupindura nguva zvakare yakachengeteka kupfuura iyo halogen mwenje yechipiri nguva yekupindura, iyo inonyanya kuoneka muharare mabhureki.
Nekuenderera mberi kwekuvandudzwa kwe LED dhizaini uye nhanho yekubatanidza pamwe nekudzikiswa zvishoma nezvishoma kwemutengo, sosi yemwenje ye LED yakasimbiswa mumagetsi emotokari mumakore achangopfuura uye yakatanga kukurumidza kuwedzera chikamu chayo mumagetsi emagetsi masisitimu.Sekureva kweTrendForce data, mwero wekupinda kwemwenje we LED mumotokari dzepasi rose uchasvika 60% muna 2021, uye mwero wekupinda kwemwenje we LED mumotokari dzemagetsi uchakwira, uchisvika makumi mapfumbamwe%.Zvinofungidzirwa kuti mwero wekupinda uchakwira kusvika 72% uye 92% zvakateerana muna 2022.
Pamusoro pezvo, matekinoroji epamusoro akadai semwenje yakangwara, marambi ekuzivikanwa, mwenje wakangwara wemhepo, MiniLED/HDR mota yekuratidzira yakamhanyisawo kupinda kweLED mukuvhenekesa mota.Nhasi, nekuvandudzwa kwemwenje wemotokari wakananga kumunhu, kuratidza kutaurirana, uye rubatsiro rwekutyaira, vese vagadziri vemotokari dzechinyakare uye vagadziri vemotokari dzemagetsi vatanga kutsvaga nzira dzekusiyanisa LED.
Kusarudzwa kwe LED yekutyaira topology
Sechiyereso chinoburitsa mwenje, LED zvinofanirwa kudzorwa nedhiraivha yekutyaira.Kazhinji, kana nhamba ye LED yakakura kana kushandiswa kwesimba kwe LED kwakakura, zvakakosha kutyaira (kazhinji mazinga akawanda emotokari).Tichifunga nezvekusiyana-siyana kwe LED musanganiswa, hazvisi nyore kuti vagadziri vagadzire akakodzera mutyairi we LED.Nekudaro, zvinogona kuve pachena kuti nekuda kwehunhu hwe LED pachayo, inogadzira kupisa kukuru uye inoda kudzikisira ikozvino yekudzivirira, saka inogara iripo ikozvino sosi drive ndiyo yakanakisa LED drive mode.
Iyo yechinyakare yekutyaira musimboti inoshandisa iyo yakazara simba mwero we LEDs muhurongwa sechiratidzo chekuyera uye kusarudza akasiyana madhiraivha e LED.Kana iyo yakazara yekumberi voltage yakakwira pane yekuisa voltage, saka iwe unofanirwa kusarudza iyo boost topology kuti isangane nezvinodiwa nevolti.Kana iyo yakazara yekumberi voltage yakadzikira pane yekupinza voltage, iwe unofanirwa kushandisa nhanho-pasi topology kuti uvandudze kugona kwese.Zvisinei, nekuvandudzwa kwezvinodiwa zve LED dimming capacity uye kubuda kwezvimwe zvinodiwa, pakusarudza vatyairi ve LED, hatifaniri kungofunga nezvehuwandu hwemagetsi, asiwo kunyatsofunga nezve topology, kushanda zvakanaka, dimming uye nzira dzekubatanidza mavara.
Sarudzo yetopology inotsamira pane chaiyo nzvimbo ye LED mune yemotokari LED system.Semuenzaniso, padanda repamusoro uye mwenje wemwenje wemotokari, mazhinji acho anofambiswa nenhanho-pasi topology.Iyi nhanho-pasi dhiraivha yakanakisa mukuita bandwidth.Iyo inogona zvakare kuwana yakanaka EMI kuita kuburikidza nedhizaini yekuparadzira spectrum frequency modulation.Iyo yakachengeteka kwazvo topology sarudzo muLED drive.Iyo EMI kuita kweboost LED drive zvakare yakanaka.Kuenzaniswa nedzimwe mhando dzetopology, ndiyo diki dhiraivha chirongwa, uye inoiswa zvakanyanya mune yakaderera uye yakakwirira mwenje marambi uye backlights emotokari.
