Afarta tilmaame ee ugu waaweyn ee muujinta ledh:
1. Iftiinka ugu badan
Ma jirto shuruud sifo cad oo loogu talagalay waxqabadka muhiimka ah ee "iftiinka ugu sarreeya". Sababtoo ah jawiga isticmaalka muraayadaha LED-yada ayaa aad u kala duwan, iftiinka (taas oo ah, dhalaalka ambient ee dadka caadiga ah ay u yaqaanaan) waa ka duwan yahay. Sidaa darteed, inta badan alaabada adag, ilaa inta hababka tijaabada ee u dhigma lagu qeexay heerka, alaab-qeybiyaha ayaa bixin doona xogta waxqabadka. Liiska (macluumaadka badeecada) ayaa ka wanaagsan shuruudaha waxqabadka gaarka ah ee lagu sheegay heerka. Kuwani dhammaantood waxay la socdaan heerarka caalamiga ah, laakiin tani waxay sidoo kale keentaa isbarbardhigga aan macquul ahayn ee tartanka, iyo isticmaalayaashu ma fahmaan tan, si "iftiinka ugu sarreeya" ee looga baahan yahay dukumeentiyada tartanka badan ayaa inta badan aad uga sarreeya baahida dhabta ah. Sidaa darteed, waxaa la soo jeediyay in si loo hago dadka isticmaala inay si sax ah u fahmaan tusmada waxqabadka ee "iftiinka ugu badan" ee bandhigga LED, waxaa lagama maarmaan ah in warshaduhu ay bixiyaan hage: mararka qaarkood, isticmaalka jawiga iftiinka kala duwan, Iftiiminta muraayadda LED waxay gaartaa qiimo gaar ah. buuxin kara shuruudaha.
2. Khaladka mawjadaha dhererka midabka aasaasiga ah
Beddel tusaha khaladka mawjadda dhererka midabka aasaasiga ah ee "qaladka mawjada dhererka midabka aasaasiga ah" una beddel "qaladka dhererka dhererka midabka aasaasiga ah", kaas oo si fiican u sharxi kara sifooyinka uu tilmaamayaashani ka tarjumayo bandhigga LED-ka. Mawjadda ugu weyn ee midabku waxa ay u dhigantaa midabka midabka isha aadamuhu arkay, kaas oo ah tiro nafsi ah iyo sifo kala sooca midba midka kale. Shuruudaha waxqabadka ee lagu qeexay halbeegga warshadaha, macno ahaan, isticmaalayaashu ma fahmi karaan inay tahay tilmaame ka tarjumaysa midnimada midabka ee bandhigga LED. Sidaa darteed, ma inaan ku hagnaa isticmaalayaasha inay fahmaan ereyga marka hore, ka dibna ay fahmaan tilmaamahan? Mise waa in aan marka hore aqoonsanno oo aan fahamnaa bandhigga LED-ka marka laga eego aragtida macaamilka, ka dibna aan siino sifada waxqabadka si fudud loo fahmi karo ee isticmaalayaashu fahmi karaan?
Mid ka mid ah mabaadi'da samaynta heerarka alaabada ayaa ah "Mabda'a Waxqabadka": "Inta suurtogalka ah, shuruudaha waa in lagu muujiyaa sifooyinka waxqabadka halkii ay ka ahaan lahaayeen naqshadeynta iyo sifooyinka sharaxaadda, habkani wuxuu ka tagayaa habka ugu weyn ee horumarinta tignoolajiyada." "Qaladka Wavelongth" waa shuruudaha naqshadeynta. Haddii lagu beddelo "midabka midabka", ma jiro LED leh mawjadda dhererka xaddidan. Isticmaalayaasha, ilaa iyo inta aad hubiso in midabka muraayadda LED-ku uu yahay mid lebbisan, uma baahnid inaad tixgeliso haddii aad isticmaasho Waa maxay farsamo ahaan macnaheedu yahay in la gaaro, ka tag inta ugu badan ee suurtogalka ah ee horumarinta tignoolajiyada, taas oo faa'iido weyn u leh horumarinta warshadaha.
3. Wareega shaqada
Sida "Mabda'a Waxqabadka" ee kor ku xusan, "Inta suurtogalka ah, shuruudaha waa in lagu muujiyaa sifooyinka waxqabadka halkii ay ka ahaan lahaayeen naqshadeynta iyo sifooyinka sharaxaadda, habkani wuxuu ka tagayaa habka ugu weyn ee horumarinta tignoolajiyada". Waxaan aaminsanahay in " degenaansho "Qeybta" ay tahay kaliya shuruudda tignoolajiyada naqshadeynta oo aan loo isticmaalin tilmaame waxqabadka heerarka sheyga LED; Dhammaanteen waan ognahay in isticmaale kasta oo daneynaya wareegga waajibaadka wadista ee shaashadda bandhigga, waxay daneeyaan saameynta shaashadda , halkii ay ka ahaan lahaayeen hirgelinta farsamadayada; waa maxay sababta aan u abuurno caqabadaha farsamada ee nafteena si aan u xaddidno horumarinta tignoolajiyada ee warshadaha?
4. Heerka dib u soo kicinta
Marka loo eego hababka cabbiraadda, waxay umuuqataa inay iska indhatirto walaacyada dhabta ah ee isticmaaleyaasha, sidoo kale ma tixgalinayso IC-yada kala duwan ee wadista, wareegyada wadista iyo hababka ay adeegsadaan soosaarayaal kala duwan, taasoo keentay inay ku adkaato tijaabada. Tusaale ahaan, dalabka shaashadda midabka buuxa ee Shenzhen Stadium, ee tijaabada muunad ee khubarada, tijaabada tilmaamuhu waxay keenaysaa dhibaatooyin badan. "soo noqnoqoshada soo noqnoqda" waa is-dhaafsiga wakhtiga loo baahan yahay si loo soo bandhigo qaab-dhismeedka shaashadda, muraayadda soo-bandhigiddana waxaa loo arkaa il iftiin ah, taas oo ah, inta jeer ee soo noqnoqda ee isha iftiinka. Waxaan si toos ah ugu tijaabin karnaa inta jeer ee liiqliiqata isha iftiinka ee shaashadda iyadoo la isticmaalayo qalab la mid ah "mitirka inta jeer ee dareenka leh" si aan u muujino tusahan. Waxaan samaynay tijaabadan anagoo adeegsanayna oscilloscope si aan u cabbirno qaabka mawjadda hadda jirta ee LED-ka ee midab kasta si loo go'aamiyo "soo noqnoqoshada soo noqnoqda", taas oo ah 200Hz oo ka hooseysa goobta cad; Heerarka cawlan ee hooseeya sida 3-heer cawl, inta jeer ee la cabbiray waa sida ugu sareysa 200Hz. In ka badan toban k Hz, oo lagu qiyaasay PR-650 spectrometer; Dhib maleh goobta cad ama heerka cawl ee 200, 100, 50, iwm
Soo bandhigida hogaanka halabuurka u qaabaysan foosto-khamriga ee Zhongshan, Shiinaha
Qodobbada kor ku xusan waa uun sharraxaad kooban oo ku saabsan sifooyinka dhowr bandhig oo LED ah. Waxa kale oo jira qaar badan oo "nolosha shaqada", "waqtiga celceliska u dhexeeya guuldarrada", iwm. Ma jiro hab tijaabo ah oo lagu isticmaali karo waqti gaaban. Waqtiga si loo xaqiijiyo in bandhiga LED uu buuxiyo shuruudaha xasilloonida, kalsoonida ama nolosha; shuruudahan waa in aan la cayimin. Soo saaraha ayaa sameyn kara dammaanad, laakiin ma beddeli karo shuruudaha. Waa fikrad ganacsi, fikrad qandaraas, ma aha fikrad farsamo. Warshaduhu waa inay lahaadaan bayaan cad oo arrintan ku saabsan, taas oo faa'iido weyn u leh dadka isticmaala, soo saarayaasha iyo guud ahaan warshadaha.
Sida loo hago isticmaalayaasha si ay si sax ah u fahmaan badeecada nidaamka adag sida bandhiga LED, wali waa lagama maarmaan in ururada warshadaha ay qabtaan goleyaal tignoolajiyadeed oo badan oo LED ah, iyo in la falanqeeyo badeecadan marka loo eego dadka isticmaala oo haga isticmaaleyaasha si sax ah. faham muujinta LED. .
