Nigute ubushyuhe bwa LED buhuza ubushyuhe butangwa?
Impamvu LED ishyuha ni ukubera ko ingufu z'amashanyarazi ziyongereye zose zidahinduka ingufu zoroheje, ariko igice cyacyo gihinduka ingufu zubushyuhe.Imikorere yumucyo wa LED kuri ubu ni 100lm / W gusa, kandi imikorere ya electro-optique ihindura ni 20 ~ 30% gusa.Nukuvuga ko hafi 70% yingufu zamashanyarazi zihinduka ingufu zubushyuhe.
By'umwihariko, ibisekuru bya LED ihuza ubushyuhe biterwa nibintu bibiri.
1. Imikorere ya kwant imbere ntabwo iri hejuru, ni ukuvuga, iyo electron nu mwobo byongeye guhurizwa hamwe, fotone ntishobora kubyara 100%, ubusanzwe bita "kumeneka kwubu", bigabanya umuvuduko wubwiyongere bwabatwara mukarere ka PN.Imiyoboro yamenetse igwijwe na voltage nimbaraga ziki gice, zihindurwamo ingufu zubushyuhe, ariko iki gice ntikibara igice cyingenzi, kuko imikorere ya fotone yimbere igera kuri 90%.
2.Fotone yakozwe imbere ntishobora gusohoka hanze ya chip hanyuma amaherezo igahinduka ubushyuhe.Iki gice nigice cyingenzi, kuberako kwant kwubu ikora yitwa hanze ni 30% gusa, kandi ibyinshi bihinduka ubushyuhe.Nubwo imikorere yumucyo yamatara yaka ari mike cyane, hafi 15lm / W gusa, ihindura ingufu zamashanyarazi hafi yingufu zose kandi ikayirasa.Kuberako imbaraga nyinshi zumucyo zitagira infragre, imikorere yumucyo ni mike cyane, ariko ikuraho ikibazo cyo gukonja.Ubu abantu benshi kandi benshi bitondera ubushyuhe bwa LED.Ni ukubera ko urumuri rwangirika cyangwa ubuzima bwa LED bifitanye isano itaziguye nubushyuhe bwayo.
Imbaraga-nyinshi LED yumucyo wera hamwe na LED chip ubushyuhe bwo gukwirakwiza
Uyu munsi, LED yumucyo wera urimo gukoreshwa buhoro buhoro mubice bitandukanye.Abantu bumva umunezero utangaje uzanwa nimbaraga nyinshi LED yumucyo wera kandi bahangayikishijwe nibibazo bitandukanye bifatika!Mbere ya byose, uhereye kumiterere yimbaraga nyinshi LED yumucyo wera ubwayo.LED ifite ingufu nyinshi iracyafite ikibazo cyo kutagira urumuri rwinshi, igihe gito cyo gufunga ibikoresho, kandi cyane cyane ikibazo cyo gukwirakwiza ubushyuhe bwa chip ya LED, bigoye kugikemura, kandi ntishobora gukoresha inyungu ziteganijwe gukoreshwa na LED yera.Icyakabiri, uhereye kubiciro byisoko ryumuriro mwinshi LED urumuri rwera.Muri iki gihe ingufu nyinshi LED iracyari ibicuruzwa byoroheje byera, kuko igiciro cyibicuruzwa bifite ingufu nyinshi biracyari hejuru cyane, kandi ikoranabuhanga riracyakeneye kunozwa, bityo ibicuruzwa byera byera cyane LED ntibishobora gukoreshwa numuntu ubishaka. Kuri Koresha.NkaLED yerekana.Reka dusenye ibibazo bifitanye isano nimbaraga nyinshi LED ikwirakwiza.
Mu myaka yashize, hashyizweho ingufu ninzobere mu nganda, hashyizweho ibisubizo byinshi byo kunoza ubushyuhe bwo gukwirakwiza ubushyuhe bwa LED zifite ingufu nyinshi:
Ⅰ.Ongera ubwinshi bwurumuri rutangwa mukongera ubuso bwa chip ya LED.
Ⅱ.Kwemeza pake yibice bito bito bya LED.
Ⅲ.Hindura ibikoresho byo gupakira LED nibikoresho bya fluorescent.
Noneho birashoboka kunoza burundu ikibazo cyo gukwirakwiza ubushyuhe bwimbaraga nyinshi LED yumucyo wera ukoresheje uburyo butatu bwavuzwe haruguru?Mubyukuri, biratangaje!Mbere ya byose, nubwo twongera ubuso bwa chip ya LED, dushobora kubona urumuri rwinshi (urumuri runyura mugice cyigihe) Umubare wibiti kuri buri gice ni urumuri rwinshi, kandi igice ni ml).Nibyiza kuriInganda LED.Turizera kugera ku mucyo wera dushaka, ariko kubera ko agace nyako ari kanini cyane, hari ibintu bimwe na bimwe bivuguruzanya mubikorwa byo gusaba no muburyo.
None se mubyukuri ntibishoboka gukemura ikibazo cyingufu nyinshi LED yumucyo wera?Birumvikana ko bidashoboka gukemura.Urebye ibibazo bibi biterwa no kongera agace ka chip gusa, abakora urumuri rwera rwa LED bateje imbere ubuso bwamashanyarazi menshi ya LED bakoresheje uduce duto duto twa LED dukurikije iterambere rya electrode hamwe na flip-chip imiterere kugirango igere kuri 60lm./ W hejuru ya luminous flux hamwe nubushobozi buke bwo kumurika hamwe no gukwirakwiza ubushyuhe bwinshi.
Mubyukuri, hari ubundi buryo bushobora kunoza neza ikibazo cyo gukwirakwiza ubushyuhe bwa chip-LED ifite ingufu nyinshi.Nukugusimbuza plasitike cyangwa plexiglass yabanje hamwe na silicone resin kubintu byapakiye urumuri rwera.Gusimbuza ibikoresho byo gupakira ntibishobora gukemura gusa ikibazo cyo gukwirakwiza ubushyuhe bwa chip ya LED, ariko kandi bizamura ubuzima bwa LED yera, yica inyoni ebyiri n'ibuye rimwe.Icyo nshaka kuvuga nuko hafi yingufu zose zumucyo wera LED ibicuruzwa nkimbaraga nyinshi LED itara ryera rigomba gukoresha silicone nkibikoresho bya ensapsulation.Kuki silika gel igomba gukoreshwa nkibikoresho byo gupakira muri LED ifite ingufu nyinshi ubu?Kuberako silika gel ikuramo munsi ya 1% yumucyo wuburebure bumwe.Nyamara, igipimo cyo kwinjiza epoxy resin kugera kuri 400-459nm yumucyo kiri hejuru ya 45%, kandi biroroshye gutera kwangirika kwumucyo bitewe nubusaza buterwa no kumara igihe kirekire urumuri ruto ruto.
Nibyo, mubikorwa nyabyo nubuzima, hazabaho ibibazo byinshi nko gukwirakwiza ubushyuhe bwamashanyarazi menshi ya LED yumucyo wera, kuko uko ushyira mugaciro urumuri rwinshi rwa LED urumuri rwera, niko ibibazo byimbitse kandi bigoye bizagenda kugaragara!Ibiranga chip ya LED nubushyuhe bukabije butangwa mubunini buto cyane.Ubushyuhe bwa LED ubwabwo ni buto cyane, bityo ubushyuhe bugomba gukorwa ku muvuduko wihuse, bitabaye ibyo ubushyuhe bwo hejuru bukabyara.Kugirango dukure ubushyuhe muri chip uko bishoboka kose, hari byinshi byahinduwe ku miterere ya chip ya LED.Kugirango tunoze ubushyuhe bwa LED chip ubwayo, iterambere nyamukuru nugukoresha ibikoresho bya substrate hamwe nubushyuhe bwiza bwumuriro.
Kugenzura ubushyuhe bwamatara ya LED birashobora kandi gutumizwa muri micro-mugenzuzi
Kuburyo bunoze bwimbaraga za NTC, niba ushaka kugera ku gishushanyo cyiza, nuburyo bworoshye bwo gukora igishushanyo mbonera cyumutekano hamwe na MCU.Mu mushinga witerambere, imiterere ya LED yumucyo module irashobora kugabanywa niba urumuri ari Niba ruzimye cyangwa rutazimye, hamwe na gahunda yo guca imanza zerekana uburyo bwo kuburira ubushyuhe no gupima ubushyuhe, hubatswe uburyo bunoze bwo gucunga amatara yubwenge. .
Kurugero, niba hari itara ryubushyuhe bwamatara, ubushyuhe bwa module buracyari murwego rwemewe binyuze mubipimo byubushyuhe, kandi inzira isanzwe irashobora kugumaho kugirango isanzwe ikwirakwiza ubushyuhe bwimikorere binyuze mumashanyarazi.Kandi iyo umuburo umenyesheje ko ubushyuhe bwapimwe bugeze ku gipimo cyo gushyira mu bikorwa uburyo bukonje bukonje, MCU igomba kugenzura imikorere yumufana ukonje.Mu buryo nk'ubwo, iyo ubushyuhe bwinjiye muri zone, uburyo bwo kugenzura bugomba guhita buzimya isoko yumucyo, kandi mugihe kimwe cyemeza ubushyuhe nanone amasegonda 60 cyangwa amasegonda 180 nyuma ya sisitemu yazimye.Iyo ubushyuhe bwa LED bukomeye-leta yumucyo isoko module igeze ku gaciro gasanzwe, ongera utware urumuri rwa LED hanyuma ukomeze gusohora urumuri.
