I. Igenzura ryerekanwa kumatara ya LED
Ibisabwa byo kugaragara: Ukoresheje igenzura ryerekanwa kuri shell hanyuma ugatwikira hafi 0.5m uvuye ku itara, nta guhinduka, gushushanya, gukuramo, gusiga irangi n'umwanda;imiyoboro y'itumanaho ntabwo ihinduwe;umuyoboro wa fluorescent ntabwo urekuye kandi nta majwi adasanzwe.
Ibipimo by'ibipimo: Ibipimo byerekana bigomba kuba byujuje ibisabwa gushushanya.
Mibisabwa mu kirere: Ibikoresho n'imiterere y'itara bigomba kuba byujuje ibisabwa gushushanya.
Ibisabwa mu nteko: Kwizirika imigozi hejuru y itara bigomba gukomera nta gusiba;nta burr cyangwa inkombe ikarishye;amasano yose agomba kuba ashikamye kandi ntarekuye.
II.Ibisabwa ku mikorere ya LED Itara
Amatara ya LED akeneye sisitemu nziza yo gukonjesha.Kugirango yemeze imirimo isanzwe yamatara ya LED, ubushyuhe bwumuzunguruko wa aluminiyumu ntibushobora kuba hejuru ya 65 ℃.
Amatara ya LED agomba kugiraimikorereyo kurinda ubushyuhe burenze.
Amatara ya LED agenzura uruziga rudasanzwe kandi rugomba kuba rufite ibikoresho byo guhuza hamwe na 3C, UL cyangwa VDE ibyemezo byo kurinda birenze urugero mugihe habaye uruziga rudasanzwe.
Amatara ya LED arashobora kurwanya ibintu bidasanzwe.Muyandi magambo, buri cyiciro cya LED gitwarwa nubwigenge buhoraho bwo gutanga amashanyarazi.Mugihe cyumuzunguruko mugufi uterwa no gusenyuka kwa LED, amashanyarazi ahoraho agomba gutanga akazi keza kumuzunguruko hamwe numuyoboro uhamye.
Amatara ya LED agomba kuba adafite ubushyuhe kandi ashobora gukuraho ububobere no guhumeka.Ikibaho cyimbere cyamatara ya LED kigomba kuba kitagabanije kandi gihumeka hamwe nigikoresho cyo guhumeka.Niba amatara ya LED yibasiwe nubushyuhe, azakomeza gukora neza kandi akureho ububobere bitewe nubushyuhe butanga mugihe cyakazi.
Ikigereranyo kiri hagati yamanuka yose hamwe ningufu zikoreshwa mumatara ya LEDis ≥56LM／W.
III.Ikizamini cyurubuga kumatara ya LED
1. Guhindura ikizamini cyubuzima
Kuri voltage yagenwe hamwe ninshuro yagenwe, amatara ya LED akora amasegonda 60 hanyuma akareka gukora amasegonda 60, azenguruka inshuro 5000, amatara ya fluorescentirashoborauracyakora bisanzwe.
2. Ikizamini kiramba
Mubidukikije bidafite umuyaga mwinshi mubushyuhe 60 ℃ ± 3 ℃ nubushuhe ntarengwa ugereranije 60%, amatara ya LED akora amasaha 360 ubudahwema kuri voltage yagenwe hamwe ninshuro yagenwe.Amashanyarazi yabo ntagomba kuba munsi ya 85% yambere ya luminous flux nyuma yibyo.
3. Kurinda birenze urugero
Kurinda birenze urugero kuri enterineti irangiye, niba ibyinjijwemo voltage ari 1,2 igiciro cyagenwe, igikoresho cyo gukingira amashanyarazi kirenze gukora;nyuma yuko voltage imaze gukira kuba ibisanzwe, amatara ya LED nayo agomba gukira.
4. Hubushyuhe n'ubushyuhe buke
Ubushyuhe bwikizamini ni -25 ℃ na + 40 ℃.Igihe cyo gukora ni amasaha 96 ± 2.
-Higipimo cy'ubushyuhe
Ingero zipakurura zipakishijwe amashanyarazi mubushyuhe bwicyumba zishyirwa mubyumba byipimisha.Hindura ubushyuhe mucyumba kuba (40 ± 3) ℃.Ibyitegererezo kuri voltage yagenwe hamwe na frequency frequency ikora amasaha 96 ubudahwema kubushyuhe (igihe kizatangira guhera igihe ubushyuhe bumaze guhagarara).Noneho hagarika amashanyarazi ya chambre, fata ibyitegererezo hanyuma ubigumane mubushyuhe bwicyumba amasaha 2.
-Ikizamini cy'ubushyuhe buke
Ingero zipakurura zipakishijwe amashanyarazi mubushyuhe bwicyumba zishyirwa mubyumba byipimisha.Hindura ubushyuhe mucyumba kuba (-25 ± 3) ℃.Ibyitegererezo kuri voltage yagenwe hamwe na frequency frequency ikora amasaha 96 ubudahwema kubushyuhe (igihe kizatangira guhera igihe ubushyuhe bumaze guhagarara).Noneho hagarika amashanyarazi ya chambre, fata ibyitegererezo hanyuma ubigumane mubushyuhe bwicyumba amasaha 2.
Test ibisubizo byurubanza
Kugaragara n'imiterere y'amatara ya LED ntibishobora kugira impinduka zigaragara mugenzura.Impuzandengo yo kumurika mu kizamini giheruka ntishobora kuba munsi ya 95% kumurika mu kizamini cya mbere;gutandukana hagati yubuso bwurukiramende nyuma yikizamini hamwe nubuso bwambere bwurukiramende ntibishobora kuba hejuru ya 10%;gutandukana k'uburebure cyangwa ubugari bw'urukiramende ntibishobora kuba hejuru ya 5%;gutandukana kwinguni hagati yuburebure nubugari bwurukiramende ntibishobora kuba hejuru ya 5 °.
5. Fikizamini cyo kugwa
Ikigereranyo kitarishyuwe hamwe na pake yuzuye muburebure bwa 2m igwa kubuntu inshuro 8.Bagwa inshuro 2 mubyerekezo 4 bitandukanye.
Ibyitegererezo nyuma yikizamini ntibishobora kwangirika kandi ibifunga ntibishobora kurekurwa cyangwa kugwa;hiyongereyeho, imikorere yintangarugero igomba kuba ibisanzwe.
6. Kwinjiza ikizamini
Luminous fluxbivugaimbaraga z'imirasire amaso yumuntu arashobora kumva.Iringanato ibicuruzwa byingufu zimirasire kumurongo wumurongo mugihe hamwe no kugaragara ugereranije kumurongo.Ikimenyetso Φ (cyangwa Φr) bisobanura urumuri rutangaje;igice cya luminous flux ni lm (lumen).
a.Urumuri rwinshi ni luminous ubukana bugera, amababi cyangwa akanyura hejuru yuhetamye mugihe cyumwanya.
b.Urumuri rwinshi ni igipimo cyumucyo uva mumatara.
-Ibara ryerekana amabara (Ra)
ra ni ibara ryerekana amabara.Kugirango isuzumabumenyi ryinshi ryerekana amabara yatanzwe yumucyo, igitekerezo cyo gutanga amabara cyerekana.Sobanura ibara ryerekana ibara ryerekana urumuri rusanzwe kuba 100;ibara ryerekana amabara yandi masoko yumucyo ari munsi ya 100. Ibintu byerekana ibara ryabyo munsi yizuba nizuba ryinshi.Munsi yamatara ya gaze asohora ibintu bitagaragara, ibara rizagoreka muburyo butandukanye.Urwego rwamabara nyayo yerekana urumuri rwitwa ibara ryerekana ibara ryumucyo.Impuzandengo yerekana amabara yerekana amabara 15 asanzwe asobanurwa na Re.
-Ubushyuhe bwamabara: igipimo cyo gupima kirimo ibara mumirase yumucyo.Mubyigisho, ubushyuhe bwumubiri wumukara bisobanura ibara ryumubiri wumukara wuzuye watanzwe kuva kuri zeru zuzuye (-273 ℃) kugeza ku bushyuhe bwo hejuru nyuma yo gushyuha.Umubiri wumukara umaze gushyuha, ibara ryarwo rihinduka umukara ugahinduka umutuku, umuhondo,hanyumacyera naamaherezoubururu.Umubiri wumukara umaze gushyuha kugirango ube mubushyuhe runaka, ibice byerekana ibintu biri mumucyo utangwa numubiri wumukara byitwa ubushyuhe bwamabara kubushyuhe.Igice cyo gupima ni “K” (Kelvin).
Niba ibice byerekana ibintu biri mumucyo utangwa nisoko yumucyo bisa nkurumuri rwatanzwe numubiri wumukara mubushyuhe runaka, byitwa * K ubushyuhe bwamabara.Kurugero, ibara ryurumuri rwa 100W rumuri ni kimwe numubiri wumukara wuzuye mubushyuhe 2527 ℃.Ubushyuhe bwamabara yumucyo utangwa nigitereko kizaba:(2527 + 273)K = 2800K.
IV.Ikizamini cyo gupakira amatara
1.Ibikoresho byo gupakira ibikoresho byakoreshejwe bigomba kuba byiza.Ipaki yakoreshejwe igomba gutsinda ikizamini cyubusa.
2.Icapiro kumapaki yinyuma rigomba kuba ryukuri, harimo mask nkuru, ikimenyetso cyuruhande, umubare wateganijwe, uburemere bwurwego, uburemere bwuzuye, umubare wicyitegererezo, ibikoresho, agasanduku nimero, gushushanya icyitegererezo, aho byaturutse, izina ryisosiyete, aderesi, ikimenyetso cyerekana, Ikimenyetso cya UP, ikimenyetso cyo gukingira ubushuhe nibindi.inyuguti n'imibare bizasobanuka nta shusho yizimu.Ibara ryicyiciro cyose kizahuza ibara palette;Kugaragara kwa chromatic aberration mubice byose bizirindwa.
3.Ibipimo byose bigomba kuba bikwiye:ikosa ± 1/4;gukanda kumurongo bigomba kuba byiza kandi bifunze burundu.Kwemeza ibikoresho nyabyo.
4.Kode yumurongo igomba kuba isobanutse kandi yujuje ibyangombwa bisikana.
