Waqtiga bilowga:Waxaa jira laba nooc oo ah wakhtiga bilawga ah ee qalabka nalalka isboortiga: bilaw degdeg ah iyo dib u dhac, kuwaas oo u baahan in si macquul ah loo doorto iyadoo loo eegayo shuruudaha mashruuca gaarka ah.
Soo jiidashada badan ee hadda jira:Marka nalka la bilaabo, waxaa jira qulqul weyn oo ka sarreeya kan hadda la qiimeeyay, kaas oo loo yaqaan hadda impulse.Saamiga imminka hadda socda iyo kan la qiimeeyay ee hadda shaqeeya waxa loo yaqaannaa jilbaha hadda jira.Qiimaha yar, waa yaraanta saameynta habka qaybinta awoodda, taas oo ka badbaado badan.Xaaladaha caadiga ah, bilawga degdega ah ee dareenka iftiinka isboortiga ee LED-ka ee hadda jira waa mid aad u weyn, ilaa ku dhawaad 40 jeer;halka dib u dhac ku yimid bilawga aaladda nalalka ciyaaraha ee aadka u badan ee hadda jira ay aad u yar tahay, in ka yar 2 jeer.Nalka halide birta ah waxa uu leeyahay sifo bilow ah oo daahday, sidaa awgeed saamaynteeda tirada badan ee hadda jirta sidoo kale waa yar tahay, guud ahaan wax ka yar 2 jeer.
Heerka isbeddelka korantada qulqulka iftiinka:Halbeeggani waxa uu ka tarjumayaa heerka saamaynta isha iftiinka isboorti ee leexashada danabku, waana saamiga isbeddelka qulqulka iftiinka iyo heerka isbeddelka korantada.
Tijaabooyinku waxay muujiyeen in iftiinka isboortiga ee LED uu leeyahay isbeddel hoose ee korantada qulqulka iftiinka, kuwaas oo ah Δφ%/ΔU%.Marka danabku uu yahay leexasho togan, ka dibna Δφ%/ΔU%=0.092, marka danabku uu leexdo taban, ka dibna Δφ%/ΔU%=0.075.
Si kastaba ha ahaatee, tilmaantan nalalka halide biraha ah ayaa aad u liita oo aan lagu qanacsanayn.Marka leexashada danabku uu togan yahay, Δφ%/ΔU%=38/10=3.8;Marka leexashada danabku uu taban yahay, ka dibna Δφ%/ΔU%=28/10=2.8.
Tilmaamaha nalalka halide biraha ah waa kuwo aad u weyn, iyo isbeddelada tamarta ayaa saameyn weyn ku leh qulqulka iftiinka.Qiimaha nalka LED waa mid yar, in ka yar 3% ee nalka halide birta ah, taas oo ah, qulqulka iftiinka ayaa weli ah mid aan isbeddelin marka loo eego baaxad ballaadhan oo koronto ah, wuxuuna leeyahay sifooyin koronto oo wanaagsan.
THD:Sababtoo ah aaladaha nalalka ciyaaraha ayaa u badan culeysyo hal waji ah, harmonics-yadu waa inta badan seddexaad.Ma u baahan tahay in la xasuusiyo, ma aha oo kaliya in ay fiiro gaar ah u leh dhibaatada harmonic ee nalalka iyo faynuusyada, laakiin sidoo kale dhibaatada harmonic ee nidaamka xakamaynta, gaar ahaan module dimming waxay u badan tahay in ay keento kororka harmonics.
Isku dheelitir la'aanta saddexda waji:Dhibaatadani maaha mid u gaar ah iftiinka ciyaaraha.Dhammaan qalabka korantada ee hal-waji ah ayaa laga yaabaa inay lahaadaan isku dheelitir la'aanta culeyska saddexda weji.Ugu horreyntii, waxaa lagama maarmaan ah in la xalliyo dhibaatada naqshadeynta, si siman u qaybiya culeyska hal-waji ah ee saddexda weji, iyo in la ilaaliyo dheelitirka culeyska saddex-waji sida ugu macquulsan ee hababka xakamaynta kala duwan.Marka labaad, isku day in aad ilaaliso saddexda waji ee qalliinka dheellitiran inta ugu badan ee suurtogalka ah inta lagu jiro hawlgalka.
Heerka ka-hortagga shoogga korantada ee nalka LED:Nalalka ciyaaraha dibadda waa in loo kala saaraa sida Class I, iyo qalabka ciyaaraha ee gudaha wuxuu noqon karaa fasalka I ama II.Iftiinka biyaha hoostooda waa inuu isticmaalo danab lagu qiimeeyay AC oo aan ka badnayn 12V ama DC oo aan ka badnayn 30V.Nalalka fasalka III.
Ilaalinta wareegga gaaban:Tani waa shuruud lagama maarmaan ah oo aasaasi ah, waana qaabeynta caadiga ah.
Ilaalinta xad dhaafka ah:Tani waa shuruud la doortay.Waxaa lagu talinayaa in la dejiyo goobo heer hoose iyo dhexdhexaad ah;waxaa lagu talinayaa in aan la dhigin goobo heer sare ah, ama aan la dejin ilaalinta culeyska xad dhaafka ah ee ka shaqeeya digniinaha.
Ilaalinta ficilka hadda jirta ee hadhay:goobo hoose ayaa la dejin karaa, dabcan, ama maya;Goobaha heerka-dhexe waa in aan la dejin, ama aan la dejin wax ka-hortagga ficilka hadda jira ee ku shaqeeya qaylo-dhaanta.
