I. Visual Inspection paMarambi e LED
Zvinodiwa zvekuonekwa: Nekutarisa kwekuona pane shell uye kuvhara anenge 0.5m kure nemwenje, hapana deformation, scratch, abrasion, pende yakabviswa uye tsvina;mapini ekusangana haana kuremara;fluorescent chubhu haina kusununguka uye hapana ruzha rusina kujairika.
Dimensional zvinodiwa: Zviyereso zvimiro zvinosangana nezvinodiwa pakudhirowa.
Material zvinodiwa: Zvishandiso uye chimiro chemwenje zvinosangana nezvinodiwa pakudhirowa.
Zvido zveGungano: Kusimbisa screws pamusoro pemwenje inofanira kusimbiswa pasina kusiiwa;hapana chinopinza kana chinopinza;zvese zvinongedzo zvichave zvakasimba uye zvisingaregi.
II.Zvinodiwa paKuitwa kweMarambi e LED
Marambi e LED anoda yakanaka kutonhora system.Kuvimbisa basa rakajairwa remarambi eLED, tembiricha yealuminium-based circuit board haifanire kunge yakakwira kupfuura 65 ℃.
Marambi e LED anofanira kunge anebasayekudzivirira kwepamusoro-tembiricha.
Marambi e LED anodzora dunhu risingaite uye anofanirwa kunge aine fusing mudziyo ine 3C, UL kana VDE certification ye overcurrent dziviriro kana paine abnormal circuit.
Marambi e LED anozokwanisa kurwisa kusagadzikana.Mune mamwe mazwi, yega yega LED akateedzana inofambiswa neyakazvimirira inogara iripo magetsi magetsi.Kana iri pfupi redunhu rakakonzerwa nekuparara kwe LED, iyo inogara iripo magetsi magetsi inovimbisa basa rakachengeteka redunhu rine yakagadzikana ikozvino.
Mwenje we LED uchave wakanyorova uye unokwanisa kubvisa kunyorova uye kufema.Yemukati redunhu bhodhi remarambi e LED anofanirwa kuve akanyorova-chiratidzo uye anofema nemudziyo wekufema.Kana marambi e LED akabatwa nekunyorova, acharamba achishanda zvakatsiga uye kubvisa kunyorova zvichienderana nekupisa kwaanogadzira panguva yebasa.
Chiyero pakati pese kudzika kudzika uye kushandiswa kwesimba kwemarambi e LEDis ≥56LM／W.
III.Saiti Yekuyedza paMarambi e LED
1. Kuchinja bvunzo yehupenyu
Pa rated voltage uye rated frequency, marambi e LED anoshanda kwemasekonzi makumi matanhatu obva amira kushanda kwemasekonzi makumi matanhatu, ayo anotenderera ka5000, mwenje wefluorescent.anogonaachiri kushanda zvakajairika.
2. Durability test
Munharaunda isina kutenderera kwemhepo patembiricha 60 ℃ ± 3 ℃ uye yakanyanya hunyoro hunyoro 60%, marambi e LED anoshanda kwemaawa mazana matatu nemakumi matanhatu achienderera payakayerwa voltage uye yakayerwa frequency.Kupenya kwavo kunopenya hakuzove kuri pasi pe85% yekutanga kupenya kupenya mushure meizvozvo.
3. Overvoltage protection
Mukudzivirira kwe overvoltage pamagumo ekuisa, kana magetsi ekuisa ari 1.2 yakayerwa kukosha, overvoltage yekudzivirira mudziyo uchaitwa activated;mushure mekunge magetsi adzoka kuita zvakajairika, marambi e LED anozopora zvakare.
4. High tembiricha uye yakaderera tembiricha bvunzo
Test tembiricha i -25 ℃ uye +40 ℃.Nguva yekuedza ndeye 96±2 maawa.
-High tembiricha bvunzo
Masampula ebvunzo asina kuvharwa akachajwa nemagetsi patembiricha yekamuri anoiswa mukamuri yekuyedza.Gadzirisa tembiricha mukamuri kuti ive (40±3) ℃.Iwo masampuli payakayerwa voltage uye akayerwa frequency anoshanda kwemaawa makumi mapfumbamwe nematanhatu zvichienderera patembiricha (nguva ichatanga kubva panguva iyo tembiricha inogadzikana).Wobva wacheka magetsi emukamuri, tora sampuli uye uzvichengete pamhepo tembiricha kwemaawa maviri.
-Low tembiricha bvunzo
Masampula ebvunzo asina kuvharwa akachajwa nemagetsi patembiricha yekamuri anoiswa mukamuri yekuyedza.Gadzirisa tembiricha mukamuri kuti ive (-25±3) ℃.Iwo masampuli payakayerwa voltage uye akayerwa frequency anoshanda kwemaawa makumi mapfumbamwe nematanhatu zvichienderera patembiricha (nguva ichatanga kubva panguva iyo tembiricha inogadzikana).Wobva wacheka magetsi emukamuri, tora sampuli uye uzvichengete pamhepo tembiricha kwemaawa maviri.
Test result mutongo
Kuonekwa uye chimiro chemarambi e LED hachizove neshanduko iri pachena mukutarisa kwekuona.Avhareji yekuvhenekera muyedzo yekupedzisira haizove yakaderera pane 95% avhareji yekuvhenekera muyedzo yekutanga;kutsauka pakati penzvimbo yekuvhenekera rectangle mushure mekuyedzwa uye yekutanga nzvimbo yeruvheneko rectangle haifaniri kunge yakakura kupfuura 10%;kutsauka kwehurefu kana hupamhi hwerectangle haifaniri kudarika 5%;kutsauka kwekona pakati pehurefu nehupamhi hwerectangle haifaniri kudarika 5 °.
5. Free fall test
Uncharged test samples ine yakazara package pakureba 2m inodonha zvakasununguka ka8.Vanowira ka2 mumativi mana akasiyana.
Iwo masampula mushure mekuyedzwa haazokuvadzwa uye zvisungo hazvizoreruke kana kudonha;uyezve, mabasa emasampuli achave akajairwa.
6. Kubatanidza sphere test
Luminous fluxzvinorevasimba remwaranzi yemwaranzi maziso evanhu anogona kunzwa.Zvakaenzanato chigadzirwa chemwaranzi simba pane wave bhendi munguva yeyuniti uye kuoneka kwehama pabhendi rewave.Chiratidzo Φ (kana Φr) chinoreva kupenya kunopenya;chikamu chechiedza chinopenya chinonzi lm (lumen).
a.Luminous flux intensity inopenya inosvika, inosiya kana kupfuura curved surface per unit time.
b.Luminous flux ireshiyo yechiedza chinobuda mugirobhu.
-Rura rekupa index (Ra)
ra is color rendering index.Pakuongororwa kwehuwandu pakuratidzwa kweruvara kwechiedza, pfungwa yemavara ekuratidza indekisi inosumwa.Tsanangura indekisi yeruvara rwekuvhenekesa kwakajairika kuve 100;indekisi yeruvara inoratidzira yemamwe masosi emwenje yakadzikira pane 100. Zvinhu zvinoratidzira ruvara rwazvo chairwo pasi pechiedza chezuva nechiedza chechiedza.Pasi pegaseous discharge rambi ine discontinuous spectrum, ruvara ruchakanganisa mumadhigirii akasiyana.Chiyero chekuratidzwa kweruvara chaiko kwechiedza chinodaidzwa kuti color rendering of light source.Avhareji yemavara ekupa indekisi yegumi neshanu mavara akajairika anomiririrwa naRe.
-Color tembiricha: chiyero chekuyera chine ruvara mumwaranzi wechiedza.Muchiono, tembiricha yemuviri mutema inoreva ruvara rwemuviri mutema wakazara unoratidzwa kubva kune absolute zero degree (-273 ℃) kune tembiricha yepamusoro mushure mekupisa.Mushure mekunge muviri mutema wapisa, ruvara rwayo runoshanduka kubva kune dema kuenda kune tsvuku, yero,zvinochena uyepakupedzisirabhuruu.Mushure mekunge muviri mutema wadziirwa kuti uve pane imwe tembiricha, chikamu chinotaridzika chiri muchiedza chinoburitswa nemuviri mutema chinodaidzwa kuti tembiricha yeruvara patembiricha.Chiyero chechiyero ndi "K" (Kelvin).
Kana iyo spectral component iri muchiedza chinoburitswa nemwenje sosi yakafanana neyechiedza chinoburitswa nemuviri mutema pane imwe tembiricha, inodaidzwa kuti *K color tembiricha.Semuenzaniso, ruvara rwechiedza che100W girobhu yakafanana neiyo yemuviri mutema chaiwo patembiricha 2527 ℃.Kupisa kwemavara kwechiedza chinoburitswa negirobhu kuchave:(2527+273)K=2800K.
IV.LED Mwenje Packing Muedzo
1.Iyo yekurongedza bepa zvinhu inoshandiswa ichave yakarurama.Iyo paki inoshandiswa inofanirwa kupasa yemahara yekudonha bvunzo.
2.Kudhindirwa papakiti rekunze kuchave kwakaringana, kusanganisira main mask, mucherechedzo wepadivi, nhamba yeodha, huremu hwemambure, huremu hwakakura, nhamba yemuenzaniso, zvinhu, nhamba yebhokisi, mufananidzo wekudhirowa, nzvimbo yekwakabva, zita rekambani, kero, chiratidzo che frangibility, Chiratidzo cheUP, chiratidzo chekudzivirira mwando nezvimwewo. Runyoro rwakadhindwa uye ruvara zvichave zvakarurama;mavara nenhamba zvichave zvakajeka pasina chipoko mufananidzo.Ruvara rwebatch rose ruchaenderana neruvara palette;pachena chromatic aberration mubatch rose ichadziviswa.
3. Zviyero zvese zvichave zvakarurama:kukanganisa ± 1/4 inch;kudzvanya mutsara kuchave kwakaringana uye kuvharwa zvachose.Guarantee zvinhu zvakarurama.
4.Bar kodhi ichave yakajeka uye inosangana nezvinodiwa pakuongorora.
