Nalalka iftiinka LED-ka ayaa noqday kuwo caan ah sannadihii la soo dhaafay, iyaga oo iftiiminaya nolosheena oo leh isku-dhafka qumman ee isku-dhafka iyo firfircoonaanta. Haddii loo isticmaalo bandhigyada bannaanka, dhacdooyinka, ama xitaa qurxinta guriga, nalalkani waxay heleen qaddarin aad u weyn oo ku saabsan saameyntooda muuqaalka soo jiidashada leh. Laakiin wali ma la yaabtay cilmiga ka dambeeya iyaga? Nagu soo biir safarka si aad u daaha ka qaaddo aduunka xiisaha leh ee nalalka motif LED, sahaminta sida ay u shaqeeyaan iyo farsamada u keenta nolosha.

Fahamka Tignoolajiyada LED

Si loo fahmo shaqada gudaha ee nalalka motif LED, waxaa muhiim ah in la fahmo aasaaska tignoolajiyada LED (Iftiin-Emitting Diode). Si ka duwan nalalka ifaya ee dhaqameed, LED-yadu waa aaladaha gobolka adag ee sii daaya iftiinka marka uu hadda korontodu dhex maro. Xudunta LED-ku waxa ay ka kooban tahay chip semiconductor, oo sida caadiga ah ka kooban gallium nitride (GaN), kaas oo mas'uul ka ah habka iftiinka iftiinka.

Marka elektaroonnada ku jira chip-ka semiconductor-ka ay tamar ka helaan koronto, waxay ka gudbaan xaalad tamar sare oo ay u gudbaan mid hoose, iyagoo siidaaya tamar qaab photons ah. Midabka iftiinka soo baxaya wuxuu ku xiran yahay walxaha gaarka ah ee loo isticmaalo chip-ka dhexdiisa. Tusaale ahaan, gallium arsenide waxa ay soo saartaa iftiin cas, halka gallium nitride ay soo saarto iftiin buluug ah.

Farsamoyaqaannada Nalalka Motif ee LED

Nalalka LED-ku waxay isticmaalaan nalalka LED-yada oo kala duwan si ay u abuuraan naqshado soo jiidasho leh iyo qaabab. Nalalkani waxay ku dhex milmeen wareeg koontaroolaya iftiimintooda iyo wada shaqayntooda, taas oo u oggolaanaysa saamaynta iftiinka firfircoon. Koontaroolka yar yar ama guddiga wareeg ee takhasuska leh ayaa koontaroolaya isku xigxiga qaabka, xoojinta, iyo midabka nalalka, taasoo u sahlaysa fursadaha aan dhammaadka lahayn ee halabuurnimo.

Wareegga nalalka motif LED sida caadiga ah waxaa ka mid ah resistors, capacitors, diodes, iyo transistors. Resistors waxay caawiyaan habaynta socodka korantada si ay uga hortagaan isticmaalka tamarta xad dhaafka ah, halka capacitors ay kaydiyaan oo ay sii daayaan tamarta marka loo baahdo. Diodes waxay hubisaa in korontadu ay u socoto hal jiha, ka hortagga dhaawaca wareegga wareegga, iyo transistor-yadu waxay u shaqeeyaan sidii furayaasha, taas oo u oggolaanaysa in si sax ah loo xakameeyo LED kasta oo naqshadeynta ah.

Sida nalalka Motif LED ay u abuuraan saameyno kala duwan

Mid ka mid ah sifooyinka ugu cajiibsan ee nalalka motif LED waa awoodda ay u leeyihiin inay soo saaraan noocyo badan oo saameyn muuqaal ah oo soo jiidasho leh. Kala duwanaanshiyahan waxaa lagu gaaraa iyada oo loo marayo barnaamijyo caqli-gal ah iyo is-waafajinta LED-yada shakhsi ahaaneed ee gudaha wareegga. Aynu sahamno qaar ka mid ah saamaynta iftiinka caanka ah ee ay suurtogaliyeen nalalka motif LED:

1. Fade-In/Fade-Bax: LED-yadu si tartiib tartiib ah ayey uga gudbeen off ilaa dhalaal buuxa, iyagoo abuuraya saameyn tartiib tartiib ah. Saamayntan waxaa caadi ahaan loo adeegsadaa jawiga ama in lagu sawiro isbeddellada iftiinka dabiiciga ah.

2. Maroojin: LED-yada si aan kala sooc lahayn u lulaya waxa ay ku daydaan xiddigaha liqiqaya, iyaga oo ku daraya taabasho sixir muuqaal kasta. Saamayntan waxaa inta badan loo shaqeeyaa qurxinta fasaxa iyo muuqaalka bannaanka.

3. Midabka Beddelka: LED-yada leh chips casaan, cagaar, iyo buluug ayaa isku dari kara si ay u soo saaraan midabyo aan dhammaad lahayn. Iyada oo la xakameynayo xoojinta midab kasta, nalalka motif LED waxay abuuri karaan saameyn isbeddel midab leh, kor u qaadida saameynta muuqaalka ee goob kasta.

4. Baacsiga: Si isdaba joog ah u daminta iyo daminta LED-yada qaab la sii go'aamiyay waxay soo saartaa saamaynta cayrsiga. Haddii loo isticmaalo masraxa ama bandhigyada qurxinta, saameyntani waxay ku daraysaa dareenka dhaqdhaqaaqa iyo firfircoonida.

5. Strobe: LED-yada degdega u garaaca waxay abuuraan saameyn stroboscopic ah, iyagoo siinaya dhalanteedka dhaqdhaqaaqa qaboojinta ama abuurista jawi tamar sare leh ee meelaha lagu caweeyo, riwaayadaha, iyo dhacdooyinka.

Faa'iidooyinka Nalalka Motif LED

Nalalka motif LED waxay bixiyaan faa'iidooyin badan oo ku saabsan teknoolajiyada iftiinka dhaqameed, iyaga oo ka dhigaya doorasho la doorbido codsiyada kala duwan. Waa kuwan qaar ka mid ah faa'iidooyinka muhiimka ah:

1. Tamarta Tamarta: Tignoolajiyada LED-ku aad bay u tamar badan tahay, isticmaalna koronto aad uga yar marka loo eego nalalka shidan. Tani kaliya ma dhimeyso biilasha korontada laakiin sidoo kale waxay hoos u dhigtaa saameynta deegaanka iyadoo la ilaalinayo kheyraadka.

2. Adkeysiga: LED-yadu waa kuwo waara oo waara. Waxaa loo dhisay inay u adkeystaan ​​shooga, gariir, iyo kala duwanaanshiyaha heerkulka aadka u daran, taasoo ka dhigaysa mid ku habboon qalabyada dibadda.

3. Badbaadada: Si ka duwan nalalka ifaya, nalalka LED-yada waxay soo saaraan kulayl aad u yar. Tani waxay yaraynaysaa halista gubashada iyo khataraha dabka, taasoo ka dhigaysa inay ka badbaado wax ka qabashada oo ku haboon codsiyo kala duwan.

4. dabacsanaan: Nalalka motif LED waxay bixiyaan fursado naqshadeyn aan dhammaad lahayn sababtoo ah cabbirkooda yar iyo xakamaynta shakhsi ahaaneed. Si fudud ayaa loogu dhex dari karaa qaabab kala duwan, taas oo u oggolaanaysa bandhigyo nalal shaqsiyeed iyo kuwo adag.

5. Kharashka-Wax-ku-oolnimada: Inkasta oo nalalka motif LED laga yaabo inay lahaadaan kharash bilawga ah oo sarreeya marka loo eego iftiinka dhaqameed, cimrigooda dheer iyo isticmaalka tamarta yar ayaa ka dhigaya xal kharash-ku-ool ah mustaqbalka fog.

Gebogebadii, nalalka motif LED waxay ka badan yihiin muraayadaha dhalaalaya; waxay markhaati u yihiin yaababka tignoolajiyada iftiinka casriga ah. Awoodda ay u leeyihiin in ay u beddelaan meelaha caadiga ah ee soo jiidashada khibradaha muuqaalka waa natiijada injineernimada casriga ah iyo naqshadaynta hal-abuurka. Maaddaama tignoolajiyada LED-ku ay sii socoto inay horumarto, waxaan sugi karnaa xitaa waxyaabo badan oo xiiso leh oo iftiiminaya adduunkeena, taasoo naga tagaysa cabsida sayniska ee ka dambeeya dhalaalkooda soo jiidashada leh.
