Kufungidzira hupenyu hwemwenje we LED neLM-80 uye TM-21
Upenyu Hwe LED uye Pamberi Pazvino
Hupenyu hweiyo chaiyo LED iyo inoburitsa mwenje inotemerwa tembiricha yekushandisa ye LED (LED junction tembiricha) zvekuti kudzikisira tembiricha ndiko kurebesa hupenyu hwe LED. Chimwe chinhu chikuru chinokanganisa hupenyu hwe LED chine chekuita nekumberi ikozvino iyo sezvataurwa inoenzanirana nekupenya kwe LED. Kazhinji, kumberi kwazvino harisi dambudziko hombe sezvo vagadziri ve LED vanozotsanangura mashandiro akachengeteka, kunyangwe nzvimbo dzepamusoro dzichida dhizaini iri nani yekupisa singi. Kana iyo LED ichimhanya yakanyanya kupisa yakadzika kumberi mafungu anogona kuwedzera hupenyu hweiyo LED chip, kunyangwe kazhinji kana iyo LED chip ichichengetwa ichitonhorera ine yakanaka kupisa sink dhizaini (pazasi 85 ° C), nguva yehupenyu haizosiyana zvakanyanya.
L70 LED Hupenyu Tarisiro
Magirobhu emwenje e LED haawanzo kukundikana zvine njodzi senge kune incandescent predecessors. Kana vagadziri vatsanangura hupenyu hwe LED kana hupenyu hwese mwenje girobhu mumaawa vari kureva iyo L70 data inomiririra fungidziro inonzwisisika yenguva yakatorwa kuti LED irasikirwe ne30% yekupenya kwayo kana kudzikiswa kusvika. 70% yekupenya kwayo kwepakutanga, saka L70. Izvi zvinowanzotsanangurwa muhuwandu hwe30,000 kusvika 40,000 maawa uye inowanzonzi Lumen kuchengetedza kana kuderera kweLumen.
Nekudaro, mwenje we LED hauzongoerekana wakundikana asi ramba uchiburitsa mwenje zvakanaka kupfuura iyo L70 yehupenyu poindi, kunyangwe pakupenya kwakadzika kudzamara mwenje wanyanya kushomeka kuti haugone kushandiswa. Kufungidzira kunoratidza kuti mwenje we LED uchagara kwemaawa anosvika 100,000 kana kupfuura isati yadzima. Mune akawanda maapplication ndiwo "chiedza chehupenyu"! Naizvozvo, hupenyu hwe LED hunowanzo hurefu hwakakwana uye hahunyatso kuita nyaya kunze kwemaawa ekushanda akawedzerwa kana kupisa kwakanyanya kwekushanda, izvo sezvataurwa zvinogona kuguma nekugadzirwa kwakashata.
Kuverengera kweL70 Hupenyu Tarisiro uchishandisa LM-80 bvunzo data uye TM-21 Extrapolation
Kuverenga kweL70 LED life point inzira iri nyore asi inotora nguva uchishandisa iyo LM-80 bvunzo data inoda kupenya kana lumens kuyedzwa kweakawanda ma LED samples patembiricha mitatu yakasiyana, 55°C, 85°C neimwe imwe, uye kuona kurasikirwa mukusimba kwechiedza panguva dzakawanda dzenguva pamusoro pe6000 kusvika ku8000 maawa. Kuyedzwa kunogona kutora rinenge gore kuita.
Sezvakakurukurwa, kana tave neLM-80 bvunzo data yeChip LED isu tinogona kubva yawedzera tichishandisa iyo TM-21 nzira inova basa rekuzivisa uye fomula yekuona hupenyu hweL70 mumaawa eiyo LED chip kana yadzikira kusvika makumi manomwe. % yekubuda kwayo.
