I. Kuyang'ana kowoneka pa Nyali za LED
Zofunikira zowonekera: Poyang'ana pa chipolopolo ndikuphimba pafupi ndi 0.5m kutali ndi nyali, palibe mapindikidwe, kukanda, abrasion, utoto wochotsedwa ndi dothi;zikhomo zolumikizana sizimapunduka;chubu cha fulorosenti sichimamasuka ndipo palibe phokoso lachilendo.
Zofunikira za Dimensional: Miyeso ya autilaini idzakwaniritsa zofunikira pakujambula.
Mzofunikira zapamlengalenga: Zida ndi kapangidwe ka nyali zidzakwaniritsa zofunikira pakujambula.
Zofunikira pamisonkhano: Zomangira zomangira pamwamba pa nyali ziyenera kulumikizidwa popanda kusiya;palibe chotupa kapena chakuthwa;maulumikizidwe onse azikhala olimba osati omasuka.
II.Zofunikira pa Magwiridwe a Nyali za LED
Nyali za LED zimafunikira njira yabwino yozizirira.Kuti mutsimikizire kuti nyali za LED zikugwira ntchito bwino, kutentha kwa aluminium-based circuit board sikuyenera kupitirira 65 ℃.
Nyali za LED ziyenera kukhalantchitochitetezo chokwanira kwambiri.
Nyali za LED zimayang'anira kuzungulira kwachilendo ndipo ziyenera kukhala ndi chipangizo chosakanikirana ndi 3C, UL kapena VDE certification kuti chitetezedwe mopitirira muyeso ngati dera lachilendo.
Nyali za LED zitha kulimbana ndi vuto.Mwanjira ina, mndandanda uliwonse wa LED umayendetsedwa ndi magetsi odziyimira pawokha.Munthawi yaying'ono chifukwa cha kusweka kwa LED, mphamvu yamagetsi yomwe ilipo nthawi zonse imatsimikizira ntchito yotetezeka ya dera lokhazikika.
Nyali za LED ziyenera kukhala zosagwirizana ndi chinyezi ndipo zimatha kuchotsa chinyezi ndi kupuma.Gulu lamkati lamagetsi la nyali za LED liyenera kukhala lopanda chinyezi komanso lopumira ndi chipangizo chopumira.Ngati nyali za LED zikhudzidwa ndi chinyezi, zizigwirabe ntchito mosasunthika ndikuchotsa chinyezi kutengera kutentha komwe kumatulutsa panthawi yantchito.
Chiyerekezo pakati pa kutsika kwathunthu kutsika ndi kugwiritsa ntchito mphamvu kwa nyali za LEDis ≥56LM／W.
III.Kuyesa Kwatsamba pa Nyali za LED
1. Kusintha mayeso a moyo
Pamagetsi ovotera ndi ma frequency ovotera, nyali za LED zimagwira ntchito masekondi 60 kenako zimasiya kugwira ntchito kwa masekondi 60, zomwe zimazungulira nthawi 5000, nyali za fulorosenti.akhozaimagwirabe ntchito bwino.
2. Kukhalitsa mayeso
M'malo opanda mpweya kutentha kwa 60 ℃ ± 3 ℃ ndi chinyezi chokwanira 60%, nyali za LED zimagwira ntchito kwa maola 360 mosalekeza pamagetsi ovotera ndi ma frequency ovotera.Kuwala kwawo kowala sikuyenera kukhala kochepera 85% kowala kowala pambuyo pake.
3. Chitetezo cha overvoltage
Pachitetezo cha overvoltage pamapeto olowera, ngati voliyumu yolowera ndi 1.2 yovotera, chipangizo choteteza kuphulika chidzatsegulidwa;magetsi atatha kukhala abwinobwino, nyali za LED ziyambiranso.
4. High kutentha ndi otsika kutentha mayeso
Kutentha kwa mayeso ndi -25 ℃ ndi +40 ℃.Nthawi yoyeserera ndi maola 96±2.
-Hkuyesa kutentha kwa igh
Zitsanzo zoyeserera zosapakidwa zolipiridwa ndi magetsi kutentha kwachipinda zimayikidwa muchipinda choyesera.Sinthani kutentha mchipindacho kukhala (40±3) ℃.Zitsanzo za ma voliyumu ovoteledwa ndi ma frequency ovotera zimagwira ntchito kwa maola 96 mosalekeza pa kutentha (nthawiyo imayamba kuyambira pomwe kutentha kumakhazikika).Kenako dulani mphamvu ya chipindacho, chotsani zitsanzozo ndikuzisunga kutentha kwa maola awiri.
-Kuyeza kutentha kochepa
Zitsanzo zoyeserera zosapakidwa zolipiridwa ndi magetsi kutentha kwachipinda zimayikidwa muchipinda choyesera.Sinthani kutentha mchipindacho kukhala (-25±3) ℃.Zitsanzo za ma voliyumu ovoteledwa ndi ma frequency ovotera zimagwira ntchito kwa maola 96 mosalekeza pa kutentha (nthawiyo imayamba kuyambira pomwe kutentha kumakhazikika).Kenako dulani mphamvu ya chipindacho, chotsani zitsanzozo ndikuzisunga kutentha kwa maola awiri.
Tndiye chiweruzo chotsatira
Mawonekedwe ndi mawonekedwe a nyali za LED sizikhala ndi kusintha koonekeratu pakuwunika kowonekera.Kuwunikira kwapakati pamayeso omaliza sikudzakhala kutsika kuposa 95% kuunikira kwapakati pamayeso oyamba;kupatuka pakati pa dera la rectangle wowunikira pambuyo poyesedwa ndi malo oyamba a rectangle wowunikira sikuyenera kukhala wamkulu kuposa 10%;kupatuka kwa kutalika kapena m'lifupi mwa rectangle sikuyenera kukhala wamkulu kuposa 5%;Kupatuka kwa ngodya pakati pa kutalika ndi m'lifupi mwa rectangle sikuyenera kukhala kwakukulu kuposa 5 °.
5. Free kugwa mayeso
Zitsanzo zoyesa zopanda malire zokhala ndi phukusi lathunthu pamtunda wa 2m zimagwera momasuka kwa nthawi 8.Amagwa nthawi 2 motsatira njira zinayi zosiyana.
Zitsanzo pambuyo poyesedwa sizidzawonongeka ndipo zomangira sizidzakhala zomasuka kapena kugwa;kuonjezerapo, ntchito za zitsanzo zidzakhala zachilendo.
6. Integrating sphere test
Kuwala kowalaamanena zamphamvu ya radiation maso a munthu amatha kuzindikira.Ndi zofananato chopangidwa ndi mphamvu ya radiation pagulu la mafunde mu nthawi ya unit ndi mawonekedwe achibale pa band wave.Chizindikiro Φ (kapena Φr) chimatanthawuza kuwala kowala;Chigawo cha kuwala kowala ndi lm (lumen).
a.Luminous flux ndi kuwala kowala komwe kumafika, masamba kapena kudutsa pamwamba pa phiri pa nthawi ya unit.
b.Luminous flux ndi chiŵerengero cha kuwala kochokera ku babu.
- Mtundu woperekera index (Ra)
ra ndi mtundu wopereka index.Kuti muwunikire kachulukidwe ka mtundu wa gwero la kuwala, lingaliro la mtundu wosonyeza index limayambitsidwa.Tanthauzirani mlozera wosonyeza mtundu wa gwero la kuwala kokhazikika kukhala 100;Mlozera wowonetsa mitundu wa zowunikira kwina ndi wotsika kuposa 100. Zinthu zimawonetsa mtundu wawo weniweni pansi pa kuwala kwa dzuwa ndi kuwala kwa incandescent.Pansi pa nyali yotulutsa mpweya wokhala ndi sipekitiramu yosalekeza, mtundu umasokonekera mosiyanasiyana.Mlingo wa maonekedwe enieni a gwero la kuwala kumatchedwa color rendering of light source.Avereji yamitundu yoperekera mitundu yamitundu 15 yodziwika bwino imasonyezedwa ndi Re.
-Kutentha kwamtundu: gawo loyezera lomwe lili ndi mtundu wa kuwala.Mwachidziwitso, kutentha kwa thupi lakuda kumatanthauza mtundu wa thupi lakuda kwathunthu loperekedwa kuchokera ku digiri ya zero (－273 ℃) mpaka kutentha kwambiri ikatenthedwa.Thupi lakuda likatenthedwa, mtundu wake umasintha kuchokera kukuda kukhala wofiira, wachikasu;ndiyewoyera ndipotsirizabuluu.Thupi lakuda likatenthedwa kuti likhale pa kutentha kwina, chigawo cha spectral chomwe chili mu kuwala kotulutsidwa ndi thupi lakuda chimatchedwa kutentha kwa mtundu pa kutentha.Chigawo choyezera ndi “K” (Kelvin).
Ngati chigawo cha spectral chomwe chili mu kuwala kotulutsidwa ndi gwero la kuwala ndi chofanana ndi cha kuwala kotulutsidwa ndi thupi lakuda pa kutentha kwina, chimatchedwa *K mtundu wa kutentha.Mwachitsanzo, mtundu wa kuwala kwa 100W babu ndi wofanana ndi thupi lakuda kwathunthu kutentha kwa 2527 ℃.Kutentha kwamtundu wa kuwala kotulutsidwa ndi babu kudzakhala:(2527+273)K=2800K.
IV.Mayeso Onyamula Nyali za LED
1.Zinthu zonyamula mapepala zomwe zimagwiritsidwa ntchito zizikhala zolondola.Phukusi lomwe likugwiritsidwa ntchito liyenera kudutsa mayeso aulere.
2.Kusindikiza pa paketi yakunja kudzakhala kolondola, kuphatikiza chigoba chachikulu, chizindikiro cham'mbali, nambala yoyitanitsa, kulemera kwa ukonde, kulemera kwakukulu, nambala yachitsanzo, zakuthupi, nambala ya bokosi, zojambula zachitsanzo, malo omwe adachokera, dzina la kampani, adilesi, chizindikiro cha frangibility, Chizindikiro cha UP, chizindikiro choteteza chinyezi ndi zina. Fonti yosindikizidwa ndi mtundu zizikhala zolondola;zilembo ndi ziwerengero zizikhala zomveka bwino popanda chithunzithunzi cha mizukwa.Mtundu wa batch yonse ugwirizane ndi utoto wamtundu;kuwonekera kowonekera kwa chromatic mu batch yonse kupewedwa.
3. Miyeso yonse ikhale yolondola:cholakwika ± 1/4 inchi;kukanikiza kwa mzere kudzakhala kolondola ndikutsekedwa kwathunthu.Tsimikizirani zida zolondola.
4.Bar code idzakhala yomveka bwino ndikukwaniritsa zofunikira pakusanthula.
