Sidee loo abuuraa heerkulka isku xirka chip-ka LED?
Sababta ay LED-ku u kululaanayaan ayaa ah in tamarta koronto ee lagu daray aan loo wada rogin tamarta iftiinka, laakiin qayb ka mid ah ayaa loo beddelaa tamarta kulaylka.Waxtarka iftiinka LED hadda waa 100lm / W oo keliya, iyo waxtarkeeda beddelka elektiroonigga ah waa kaliya 20 ~ 30%.Taasi waa in la yiraahdo, qiyaastii 70% tamarta korantada ayaa loo beddelaa tamarta kulaylka.
Gaar ahaan, jiilka heerkulka is-goyska LED waxaa sababa laba arrimood.
1. Waxtarka quantum-ka gudaha ma sarreeyo, taas oo ah, marka electrons iyo godadka la isku daro, photons lama soo saari karo 100%, taas oo inta badan loo yaqaan "leakage hadda", taas oo yaraynaysa heerka dib-u-habaynta sidayaasha ee gobolka PN.Qulqulka qulqulka ee lagu dhufto danabku waa awoodda qaybtan, taas oo loo beddelo tamarta kulaylka, laakiin qaybtani kuma xisaabtamayso qaybta ugu muhiimsan, sababtoo ah waxtarka photon-ka gudaha ayaa hadda ku dhow 90%.
2. Sawir-qaadayaasha gudaha laga soo saaro dhamaantood laguma sii dayn karo bannaanka chip-ka oo ugu dambeyntii loo beddelo kulayl.Qaybtani waa qaybta ugu muhiimsan, sababtoo ah waxtarka hadda jira ee loo yaqaan dibadda waa qiyaastii 30% oo keliya, inteeda badanna waxaa loo beddelaa kulayl.In kasta oo waxtarka iftiinka iftiinka nalka uu yahay mid aad u hooseeya, kaliya qiyaastii 15lm/W, waxay u beddeshaa ku dhawaad dhammaan tamarta korantada tamar iftiin waxayna soo saartaa.Sababtoo ah inta badan tamarta shucaaca waa infrared, waxtarka iftiinka ayaa aad u hooseeya, laakiin wuxuu baabi'iyaa dhibaatada qaboojinta.Hadda dad badan oo badan ayaa fiiro gaar ah u leh kuleylka kuleylka LED.Tani waa sababta oo ah qudhunka iftiinka ama nolosha LED waxay si toos ah ula xiriirtaa heerkulka isgoysyada.
Codsiga iftiinka cad ee awoodda sare ee LED iyo xalalka kuleylka kuleylka LED
Maanta, alaabada iftiinka cad ee LED ayaa si tartiib tartiib ah loo isticmaalayaa meelo kala duwan.Dadku waxay dareemayaan farxad la yaab leh oo ay keentay iftiinka cad cad ee awoodda sare leh waxayna sidoo kale ka walaacsan yihiin dhibaatooyin la taaban karo oo kala duwan!Marka hore, laga bilaabo dabeecadda awoodda sare ee iftiinka cad ee LED laftiisa.LED-ga awoodda sare leh ayaa weli ka cabanaya isku midnimo liidata ee iftiinka iftiinka, cimriga gaaban ee qalabka wax lagu xiro, iyo gaar ahaan dhibaatada kuleylka kuleylka ee chips LED, taas oo ay adag tahay in la xalliyo, oo aan ka faa'iideysan karin faa'iidooyinka codsiga la filayo ee LED-ka cad.Marka labaad, laga bilaabo qiimaha suuqa ee tamarta sare ee iftiinka cad ee LED.Maanta LED-ga awoodda sare leh ayaa weli ah wax soo saar iftiin cad oo aristocratic ah, sababtoo ah qiimaha alaabta awoodda sare leh ayaa weli ah mid aad u sarreeya, tignoolajiyada ayaa weli u baahan in la hagaajiyo, sidaas darteed alaabada LED-ka ee awoodda sare leh ma isticmaali karo qof kasta oo raba. si ay u isticmaalaan.Sidabandhig LED dabacsan.Aynu kala jejebinno dhibaatooyinka la xidhiidha tamarta sare ee kuleylka LED-ka.
Sanadihii la soo dhaafay, dadaallada khubarada warshadaha, dhowr xalal hagaajin ah ayaa loo soo jeediyay kulaylka tamarta sare ee chips LED:
ⅠKordhi qadarka iftiinka iftiinka adiga oo kordhinaya aagga chip-ka LED-ka.
ⅡQabo xirmo dhowr ah chips LED-aagga yar.
ⅢBeddel alaabta baakadaha LED-ka iyo walxaha fluorescent.
Markaa suurtagal ma tahay in si buuxda loo hagaajiyo dhibaatada kuleylka kuleylka ee awoodda sare ee LED-yada iftiinka cad ee saddexda hab ee kor ku xusan?Dhab ahaantii, waa wax cajiib ah!Ugu horreyntii, inkasta oo aan kordhinno aagga chip-ka LED-ka, waxaan heli karnaa qulqulo iftiin badan (iftiinka dhex maraya halbeeg waqti ah) Tirada laydhka halkii cutubku waa qulqulka iftiinka, unuguna waa ml).Way u fiican tahaywarshadaha LED.Waxaan rajeyneynaa inaan gaarno saameynta iftiinka cad ee aan rabno, laakiin sababtoo ah aagga dhabta ah waa mid aad u weyn, waxaa jira waxyaabo liddi ku ah nidaamka codsiga iyo qaabka.
Markaa run ahaantii miyaanay suurtogal ahayn in la xalliyo dhibaatada awoodda sare ee LED-ka iftiinka iftiinka kuleylka?Dabcan, ma aha wax aan suurtagal ahayn in la xalliyo.Marka la eego dhibaatooyinka taban ee ay sababaan si fudud u kordhinta aagga chip-ka, soo-saareyaasha iftiinka cad ee LED-ku waxay hagaajiyeen dusha sare ee chip-ka awoodda sare leh ee LED-ka iyagoo soo koobaya dhowr chips-ka-yar oo LED ah iyadoo loo eegayo hagaajinta qaab dhismeedka korantada iyo flip-chip qaab dhismeedka si loo gaaro 60lm./W qulqulka iftiinka sare iyo waxtarka iftiinka hooseeya oo leh kulaylka sarreeya.
Dhab ahaantii, waxaa jira hab kale oo si wax ku ool ah u wanaajin kara dhibaatada kuleylka kulaylka ee chips-ka awoodda sare leh.Taasi waa in lagu beddelo caaggii hore ama plexiglass-kii hore ee loo yaqaan 'silicone resin' oo loogu talagalay alaabteeda baakadaha iftiinka cad.Beddelidda alaabta baakadaha ma xallin karto oo kaliya dhibaatada kuleylka kuleylka ee chip LED, laakiin sidoo kale waxay hagaajinaysaa nolosha LED-ka cad, taas oo runtii ku dishay laba shimbirood hal dhagax.Waxa aan rabo in aan sheego ayaa ah in ku dhawaad dhammaan dhammaan alaabada iftiinka cad ee awoodda sare leh sida awoodda sare ee iftiinka cad ee LED waa inay isticmaalaan silikoon sida walxaha korantada.Waa maxay sababta jelka silica loo isticmaali karo baakad ahaan tamarta sare ee LED hadda?Sababtoo ah jel silica waxay nuugtaa wax ka yar 1% iftiinka hirarka dhererka isku midka ah.Si kastaba ha ahaatee, heerka nuugista resin epoxy ilaa 400-459nm iftiinka ayaa ah mid aad u sarreeya ilaa 45%, wayna fududahay in la keeno suus iftiin leh oo halis ah sababtoo ah gabowga oo uu keeno nuugista muddada dheer ee iftiinkan gaaban ee hirarka gaaban.
Dabcan, wax soo saarka dhabta ah iyo nolosha, waxaa jiri doona dhibaatooyin badan sida kuleylka tamarta sare ee nalka iftiinka cad ee LED, sababtoo ah inta badan isticmaalka tamarta sare ee iftiinka cad ee LED, dhibaatooyinka qoto dheer iyo kuwa adag ayaa noqon doona. muuqda!Tilmaamaha chips-ka LED-ku waa kulayl aad u sarreeya ayaa lagu soo saaraa mug aad u yar.Awoodda kulaylka LED-ka lafteedu waa mid aad u yar, markaa kuleylku waa in lagu sameeyaa xawaaraha ugu dhaqsaha badan, haddii kale heerkul sare ayaa la dhalin doonaa.Si loo soo saaro kulaylka chip-ka sida ugu badan ee suurtogalka ah, horumarin badan ayaa lagu sameeyay qaab-dhismeedka chip-ka ee LED-ka.Si loo hagaajiyo kuleylka kuleylka LED-ga laftiisa, hagaajinta ugu weyn waa in la isticmaalo walxaha substrate-ka leh ee kuleylka wanaagsan.
La socodka heerkulka laambada LED sidoo kale waxaa lagu soo dejin karaa kantarool yar
Qaabka loo wanaajiyey ee awoodda NTC, haddii aad rabto inaad gaadho nashqad ka sii wanaagsan, sidoo kale waa hab ilaa xad la taaban karo si aad u sameyso naqshad badbaado oo sax ah oo leh MCU.Mashruuca horumarinta, xaaladda moduleka isha iftiinka LED waxaa loo qaybin karaa in iftiinku yahay haddii la demiyo iyo in kale, iyada oo la raacayo xukunka macquulka ah ee barnaamijka digniinta heerkulka iyo cabbirka heerkulka, habka maaraynta iftiinka smart ee qumman ayaa la dhisay. .
Tusaale ahaan, haddii ay jirto digniin heerkul ah nalka, heerkulka moduleka ayaa weli ku dhex jira meel la aqbali karo iyada oo loo marayo cabbirka heerkulka, iyo habka caadiga ah waa la ilaalin karaa si dabiici ah u baabi'iyo heerkulka hawlgalka iyada oo loo marayo saxanka kulaylka.Marka digniintu ay sheegto in heerkulka la cabbiray uu gaadhay heerka cabbirka ee hirgelinta habka qaboojinta firfircoon, MCU waa in ay xakamayso hawlgalka marawaxada qaboojinta.Sidoo kale, marka heerkulku soo galo aagga, habka xakamaynta waa inuu isla markiiba damiyaa isha iftiinka, isla markaana xaqiiji heerkulka mar labaad 60 ilbiriqsi ama 180 ilbiriqsi ka dib marka nidaamka la damiyo.Marka heerkulka moduleka isha iftiinka dawlad- adag ee LED uu gaaro qiime caadi ah, kaxee isha iftiinka LED mar kale oo sii wad inay sii dayso iftiinka.
