LED luminaire tekinoroji
LED yumucyo nisoko gakondo yumucyo bifite itandukaniro rinini mubunini bwumubiri no gukwirakwiza ahantu hatandukanye urumuri, urumuri nuburemere bwurumuri. LED detection ntishobora gukoporora ibipimo nuburyo bwo kubona urumuri gakondo. Ibikurikira nubuhanga bwo gutahura ibisanzwe LED luminaire.
Kumenya ibipimo byiza bya amatara ya LED
1, kumurika ubukana
Ubwinshi bwurumuri, ubukana bwurumuri, bivuga ubwinshi bwurumuri rusohoka kumurongo runaka. Bitewe nurumuri rwibanze rwa LED, amategeko aringaniye ntagikoreshwa murwego rwa hafi. Igipimo cya CIE127 cyerekana uburyo bubiri bwo gupima: imiterere yo gupima A (imiterere yumurima wa kure) nuburyo bwo gupima B (hafi yumurima) kugirango bapime ubukana bwurumuri. Mugihe cyumucyo mwinshi, agace kerekana ibintu byombi ni cm 1 2. Mubisanzwe, ubukana bwa luminous bupimwa ukoresheje imiterere isanzwe B.
2, luminous flux hamwe no kumenya neza urumuri
Luminous flux nigiteranyo cyumubare wumucyo utangwa nisoko yumucyo, ni ukuvuga ingano ya luminescence. Uburyo bwo gutahura burimo ubwoko bubiri bukurikira:
(1) Uburyo bwo kwishyira hamwe. Itara risanzwe n'amatara agomba kugeragezwa bikurikiranwa murwego rwo guhuza, kandi ibyo basomye mumafoto yerekana amashanyarazi byanditswe.
(2) Uburyo bwa Spectroscopic. Luminous flux ibarwa uhereye kumashanyarazi ya P (λ) ikwirakwizwa.
Imikorere ya luminous nigereranya ryumucyo utangwa nisoko yumucyo nimbaraga zikoreshwa nawo, kandi imikorere ya luminous ya LED isanzwe ipimwa nuburyo buhoraho.
3. Kugaragaza ibiranga ibintu
Kugaragaza ibintu byerekana LED ikubiyemo gukwirakwiza imbaraga, gukwirakwiza amabara, ubushyuhe bwamabara, ibara ryerekana amabara nibindi nkibyo.
Ikwirakwizwa ryingufu zerekana ko urumuri rwumucyo rugizwe nuburebure bwinshi butandukanye bwimirasire yamabara, kandi imbaraga zumuriro wa buri burebure nazo ziratandukanye. Itandukaniro ritondekanye hamwe nuburebure bwumurongo, ibyo bita imbaraga zo gukwirakwiza imbaraga zumucyo. Inkomoko yumucyo iboneka mugupima kugereranya ukoresheje spekitifotometero (monochromator) n itara risanzwe.
Ibara rihuza ibara ryerekana imibare yerekana ibara ryumucyo ku gishushanyo. Igishushanyo mbonera cyerekana ibara gifite sisitemu nyinshi zo guhuza, mubisanzwe muri sisitemu ya X na Y.
Ubushyuhe bwamabara nubunini bwurumuri rwamabara yamabara (isura yibara risa) ijisho ryumuntu ribona. Iyo urumuri rutangwa nisoko yumucyo ni kimwe nibara ryurumuri rutangwa numubiri wumukara rwose mubushyuhe runaka, ubushyuhe nubushyuhe bwamabara. Mu rwego rwo kumurika, ubushyuhe bwamabara nikintu cyingenzi gisobanura ibintu byiza bya optique yumucyo. Igitekerezo cyubushyuhe bwamabara gikomoka kumirasire ya blackbody, ishobora kuboneka mumabara ya coorite ya blackbody locus hamwe namabara ya cooride yinkomoko.
Ibara ryerekana amabara yerekana ingano urumuri rutangwa nisoko yumucyo rugaragaza neza ibara ryikintu, ubusanzwe bigaragazwa nigipimo rusange cyerekana amabara Ra, aribwo buryo bwo kubara bwerekana ibara ryerekana amabara umunani. ingero. Ibara ryerekana amabara ni ikintu cyingenzi cyerekana urumuri rwiza, rugena urwego rwimikorere yumucyo. Kunoza ibara ryerekana ibara rya LED yera nimwe mubikorwa byingenzi byubushakashatsi niterambere.
4, ikizamini cyo gukwirakwiza urumuri
Isano iri hagati yubucyo bwumucyo nu mfuruka (icyerekezo) bita pseudo-yumucyo ukwirakwiza, kandi umurongo ufunze wakozwe nogukwirakwiza byitwa urumuri rwinshi rwo gukwirakwiza umurongo. Kubera ko hari ingingo nyinshi zapima kandi buri ngingo itunganywa namakuru, mubisanzwe bipimwa na fotometero ikwirakwizwa.
5. Ingaruka yubushuhe kubiranga optique ya LED
Ubushyuhe bugira ingaruka nziza kuri LED. Umubare munini wubushakashatsi urashobora kwerekana ko ubushyuhe bugira ingaruka kumirasire ya LED hamwe na cooride yamabara.
6, gupima urumuri hejuru
Umucyo utanga isoko yumucyo mubyerekezo runaka nuburemere bwurumuri rwumucyo ahantu hateganijwe isoko yumucyo. Mubisanzwe, metero yubuso bwa metero hamwe nicyerekezo cyerekana urumuri rukoreshwa mugupima urumuri rwubuso, kandi hariho ibice bibiri byinzira igana inzira yumucyo ninzira yo gupima urumuri.
Gupima ibindi bipimo byerekana amatara ya LED
1. Gupima ibipimo by'amashanyarazi by'amatara ya LED
Ibipimo byamashanyarazi ahanini birimo imbere ninyuma ya voltage hamwe ninyuma. Bifitanye isano no kumenya niba amatara ya LED ashobora gukora bisanzwe. Nimwe murwego rwo gusuzuma imikorere yibanze yamatara ya LED. Hariho ubwoko bubiri bwibipimo byamashanyarazi bipima amatara ya LED: ni ukuvuga, iyo ikigezweho gihoraho, ibipimo bya voltage ibipimo; iyo voltage ihoraho, ibipimo bigezweho birageragezwa. Uburyo bwihariye nuburyo bukurikira:
(1) Imbere ya voltage. Imbere yimbere ikoreshwa kumatara ya LED kugirango imenyekane, kandi igitonyanga cya voltage kibyara impande zombi. Hindura agaciro kariho kugirango umenye amashanyarazi, andika ibyasomwe bijyanye kuri voltmeter ya DC, aribwo voltage yimbere ya LED luminaire. Ukurikije imyumvire isanzwe, iyo LED ikora mu cyerekezo cyerekeza, kurwanya ni bito, kandi uburyo bwo guhuza hanze ukoresheje ammeter burasa neza.
(2) Subiza inyuma. Koresha voltage ihindagurika kuri LED luminaire igeragezwa, uhindure amashanyarazi yagenwe, kandi gusoma metero iriho ni ihindagurika ryumucyo wa LED urumuri. Kimwe no gupima voltage yimbere, kubera ko kurwanya LED ihindurwa iyo imiyoboro ihanitse ari nini, metero iriho ihujwe imbere.
2, LED itara ryerekana ibizamini biranga ubushyuhe
Ibiranga ubushyuhe bwa LED bifite ingaruka zikomeye kumiterere ya optique nu mashanyarazi ya LED. Ubushyuhe bwumuriro hamwe nubushyuhe bwibihuza nibyo bintu nyamukuru biranga ubushyuhe bwa LED 2. Kurwanya ubushyuhe bivuga kurwanya ubushyuhe hagati ya PN nubuso bwamazu, ni ukuvuga ikigereranyo cyitandukaniro ryubushyuhe kumihanda yubushyuhe bugana kumashanyarazi. kumuyoboro. Ubushyuhe bwo guhuza bivuga ubushyuhe bwa PN ihuza LED.
Uburyo bwo gupima ubushyuhe bwa LED hamwe nubushyuhe bwumuriro muri rusange harimo: uburyo bwa infragre ya micro-imager, uburyo bwa spekitroscopi, uburyo bwamashanyarazi, uburyo bwo gusikana ibyuma bifotora, nibindi nkibyo. Ubushyuhe bwo hejuru bwa chip ya LED bupimwa nubushyuhe bwa infrarafurike bupima microscope cyangwa miniature ya termocouple nkubushyuhe bwo guhuza LED, kandi ubunyangamugayo ntibuhagije.
Uburyo bukoreshwa muburyo bw'amashanyarazi ni ugukoresha ibiranga ko umuvuduko wimbere wumuvuduko wa LED PN uhuza nubushyuhe bwa PN, kandi ubushyuhe bwihuza bwa LED buboneka mugupima itandukaniro ryamanuka ryimbere ryubushyuhe butandukanye.
