Shaashadaha LED-yada ayaa aad ugu badan nolosha waxayna keenaan wax badan oo ku habboon nolosheena.Mar haddii dhalaalka muraayadda LED-ka aan lagu beddeli karin iftiinka ambient-ka, waxaa jira dhibaato muujinta aan caddayn inta lagu jiro maalinta ama dhalaalaya habeenkii sababtoo ah dhalaalaya aad u badan.Haddii dhalaalka la xakameyn karo, tamarta oo keliya lama badbaadin karo, laakiin sidoo kale saameynta bandhigga ee shaashadda ayaa la sii caddayn karaa.
01led waa isha iftiinka cagaaran, faa'iidada ugu weyni waa waxtarka iftiinka sare
Horumarinta iyo horumarka sayniska maadiga ah, waxtarka iftiinka ayaa si weyn loo horumarin doonaa 10ka sano ee soo socda;Isticmaalka tamar yar, nolol dheer oo adeeg ah, agab dib loo warshadayn karo, oo aan wasakhayn deegaanka.In kasta oo dalkeennu uu soo daah furay, haddana sannadihii u dambeeyay waxa uu sidoo kale bilaabay cilmi-baadhis firfircoon iyo horumarin iyo siyaasad iyo taageero warshadeed.Marka la barbar dhigo nalka iftiimaya, LED-ku wuxuu leeyahay farqi weyn: iftiinka iftiinka asal ahaan wuxuu la siman yahay xajmiga hadda jira ee ku qulqulaya diode-baxa iftiinka.Isticmaalka habkan, iftiinka deegaanka ku xeeran waxaa lagu cabbiraa dareemayaasha indhaha, iftiinka iftiinka ayaa isbeddelaya iyadoo loo eegayo qiimaha la cabbiray, iyo saameynta isbeddelka dhalaalka ee deegaanka ku hareeraysan ayaa la ilaaliyaa, dhismuhu wuxuu u gudbiyaa dadka inay si farxad leh u shaqeeyaan.Tani kaliya ma abuurto jawi raaxo leh oo leh dhalaal joogto ah, laakiin sidoo kale waxay si buuxda u isticmaashaa iftiinka dabiiciga ah waxayna si weyn u badbaadisaa tamarta.Sidaa darteed, cilmi-baaris ku saabsan tignoolajiyada wax-ka-qabsiga LED-ka ayaa aad muhiim u ah.
02 mabaadi'da aasaasiga ah
Naqshadani waxay isticmaashaa tiirka si ay u soo dirto xogta iyo habka sawirka safka si loo xaqiijiyo qoraalka ama sawirka LED-ka.Habkan waxaa lagu daraa wareegga qalabka si loo gaaro ujeedada iftiinka guud ee shaashadda.Ka faa'iidayso sifada xasaasiga ah ee photoresistor ilaa iftiinka ambient, ururiya isbeddelka iftiinka ambient, u beddel signalka korantada oo u dir microcomputer-ka hal-chip ah, processor-ka-hal-chip wuxuu qabtaa habaynta signalada, wuxuuna koontaroolaa saamiga waajibaadka soosaarka Mawjada PWM sida uu qabo xeer gaar ah.Wareegga xakamaynta tamarta korantada ayaa lagu daraa inta u dhaxaysa hal-chip microcomputer iyo shaashadda muraayadda si loo xaqiijiyo hagaajinta dhalaalka shaashadda ee microcomputer-ka-chip-ka ah.Mawjadda PWM ee la hagaajiyay waxaa loo isticmaalaa in lagu xakameeyo wareegga xakamaynta korantada beddelka si loo hagaajiyo tamarta wax gelinta ee shaashadda, oo ugu dambeyntii la ogaado xakamaynta iftiinka shaashadda.
03 Astaamaha
Wareegga kontoroolka dhalaalka ee la qabsiga ee shaashadda soosaarka diode-ka ifaysa, kaas oo lagu garto ka kooban yahay: Aaladda gelinta qiimaha ee hore u haysay wareegga shaqada, miiska iyo isbarbardhigga cabbirka, halkaas oo miisaska iyo wareegga waajibku ay u kala horreeyaan aaladda gelinta qiimaha waxaa lagu barbar dhigayaa qiimaha hore loo dejiyay ee wareegga waajibka ee la barbardhigay cabbirka cabbirka si loo xakameeyo qiimaha wax soo saarka isbarbardhigga.
04 LED naqshadaynta qalabka habaynta nidaamka dimming adaptive
Iftiinka LED-ku wuxuu la mid yahay kan hadda socda ee dhinaca hore u socda, cabbirka hadda jirana waa la hagaajin karaa si loo hagaajiyo iftiinka iftiinka LED-ka.Waqtigan xaadirka ah, dhalaalka LED-ka guud ahaan waxaa lagu hagaajiyaa iyadoo la hagaajinayo qaabka hadda shaqeeya ama qaabka cabbirka ballaca garaaca wadnaha.Midka hore wuxuu leeyahay kala duwanaansho isku-habeyn ballaaran, toosan wanaagsan, laakiin isticmaalka awoodda sare.Markaa waa dhif in la isticmaalo.Habka cabbirka ballaca garaaca wadnaha wuxuu isticmaalaa soo noqnoqoshada sare si uu u beddelo ledhka, inta jeer ee beddelka ayaa ka baxsan xadka ay dadku dareemi karaan, si aanay dadku u dareemin jiritaanka stroboscopic.Aqoonsiga la qabsiga LED-ka-dhigid.
