Maaddaama sharciyada tamarta ay sii adkeeyeen, dadka intooda badan waxay og yihiin in LED-yada, ama dabaylaha iftiimiya, ay jiraan waqti dheer oo ay kaydiyaan tamarta. Laakiin dad yar ayaa fahma in ilahan tignoolajiyada sare ee iftiinka aanay shaqayn karin darawal LED la'aan. Dareewalada LED-ka, oo mararka qaarkood loo yaqaan sahayda korantada LED, waxay la mid yihiin ballasts loogu talagalay nalalka dhaadheer ama transformers ee nalalka korantada yar. Waxay siiyaan LED-yada korontada ay u baahan yihiin si ay ugu shaqeeyaan oo ay ugu shaqeeyaan sida ugu fiican.

Waa maxay Darawalka LED?

Darawalka LED-ka ayaa koontaroolaya inta awoodda LED ama koox ka mid ah LED-yadu u baahan yihiin. Mar haddii diode-yada iftiimiya ay yihiin aaladaha tamarta yar ee nolosha dheer iyo isticmaalka tamarta yar, waxay u baahan yihiin ilo koronto oo gaar ah.

Shaqooyinka ugu muhiimsan ee darawallada LED-yada waa inay bixiyaan koronto yar iyo ilaalinta LED-yada.

LED kasta wuxuu isticmaali karaa ilaa 30mA oo hadda ah wuxuuna ku shaqeeyaa danab qiyaastii 1.5V ilaa 3.5V. LEDs badan ayaa loo isticmaali karaa si isdaba joog ah iyo is barbar socda si loo sameeyo nalka guriga, kaas oo u baahan kara koronto wadar ah 12 ilaa 24 V DC. Dareewalka LED-ku wuxuu u rogaa AC si uu u daboolo baahiyaha wuxuuna hoos u dhigaa tamarta. Tani waxay ka dhigan tahay in korantada sare ee AC-gu, oo u dhaxaysa 120V ilaa 230V, waa in loo beddelaa danab yar oo DC ah oo loo baahan yahay.

Darawalada LED-ka sidoo kale waxay ka ilaalisaa LED-yada isbeddelka tamarta iyo hadda. Xitaa haddii sahayda dhaxe isbedesho, wareegyadu waxay xaqiijiyaan in danabka iyo hadda u socda LED-yada ay ku sii jiraan xadka ku habboon ee ay ku shaqeeyaan. Ilaalintu waxay ka joojisaa LED-yada inay helaan koronto badan iyo hadda, taas oo dhaawici karta, ama hadda aan ku filnayn, taasoo ka dhigaysa inay dhalaal yaraadaan.

Sidee bay Darawaliinta LED-ku u shaqeeyaan?

Marka heerkulka LED-ku isbeddelo, sidaas oo kale ayaa loo baahan yahay danabkeeda hore. Marka ay sii kululaato, koronto yar ayaa loo baahan yahay si ay hadda ugu dhex socoto LED-ka, si ay u isticmaasho awood dheeraad ah. Heerkulku waa marka heerkulku kor u kaco oo uu gubo LED. Heerarka wax soo saarka korontada ee darawalada LED-yada waxaa loo sameeyaa si loo daboolo baahiyaha LED-yada. Xilliga joogtada ah ee darawalku wuxuu ilaaliyaa heerkulka xasilloon isagoo ka jawaabaya isbeddelada tamarta hore.

Maxaa Darawalka LED-ka Loo Isticmaalaa?

Transformers ee nalalka iftiinka yar-yar waxay sameeyaan wax la mid ah kuwa darawallada LED-ka ay u sameeyaan LED-yada. Nalalka LED-ku waa aaladaha korantada yar ee inta badan ku shaqeeya 4V, 12V, ama 24V. Si ay u shaqeeyaan, waxay u baahan yihiin isha awoodda hadda jirta. Laakiin sababta oo ah sahayda korantada godka gidaarka waxay sida caadiga ah leeyihiin Voltage aad u sarreeya (inta u dhaxaysa 120V iyo 277V) waxayna soo saaraan hadda beddelka ah, si toos ah uma socon karaan. Maadaama celceliska korantada LED-ku uu aad ugu yar yahay beddelka caadiga ah, darawallada LED-yada gaarka ah ayaa loo isticmaalaa si loogu beddelo beddelka tamarta-sare ee hadda jira-hoose ee tooska ah.

Waxyaabaha kale ee darawalada LED-ku ay sameeyaan ayaa ah inay ka difaacaan korontadu, iyo isbeddelada, taas oo keeni karta in heerkulku kor u kaco oo iftiinka iftiinka hoos u dhaco. Nalalka LED-yada waxaa loo sameeyay inay ku shaqeeyaan oo kaliya tiro gaar ah oo amps ah.

Qaar ka mid ah darawalada LED-yada ayaa sidoo kale bedeli kara iftiinka nidaamyada LED-ka ee ku xiran iyo sida ay u kala horreeyaan midabada. Si taas loo sameeyo, waa inaad si taxadar leh u shid iyo dami LED kasta. Tusaale ahaan, nalalka cad cad waxaa badanaa lagu sameeyaa iyadoo la shiday farabadan LEDs midabyo kala duwan leh isku mar. Haddii aad damiso qaar ka mid ah LED-yada, midabka cad ayaa meesha ka baxaya.

Cabirro kala duwan oo lagu Sharaxayo Darawalada LED.

•  Dibeda vs. Dareewalka LED-ka Gudaha

Farqiga u dhexeeya darawallada LED-yada ee dibadda iyo kuwa gudaha waxaa lagu dhisi karaa nalal (gudaha), la saaro dusha sare ee qalabka iftiinka, ama xitaa bannaanka iyaga (Dibadda). Inta badan nalalka gudaha ee tamarta yar, gaar ahaan nalalka, ayaa lagu dhex dhisay darawallada LED. Tani waxay ka dhigaysaa nalalka kuwa raqiisan oo soo jiidasho leh. Dhanka kale, nalalka hoose iyo nalalka panel-ku waxay inta badan leeyihiin darawallada LED ee dibadda.

Markaad isticmaaleyso koronto badan, sida nalalka waddooyinka, nalalka daadka, nalalka garoonka, iyo nalalka koraan, darawalada LED-yada ayaa aad loo isticmaalaa in ka badan. Tani waa sababta oo ah kulaylka gudaha nalalka ayaa ka sii dara marka korontadu kor u kacdo. Waxyaabo kale oo wanaagsan oo ku saabsan darawallada LED-yada dibadda ayaa si fudud loogu beddeli karaa dayactirka.

• Beddelka Quwada Korontada vs. Nidaamiyaha Tooska ah

Sababtoo ah darawalada tooska ah ee LED aad ayey u fudud yihiin, iska caabin, MOSFET kontorool, ama IC ayaa laga yaabaa in loo baahdo si loo sameeyo LED-ga joogtada ah. Wax badan oo AC LED ah, calaamado, iyo codsiyo xariijin ayaa isticmaala iyaga. Sababtaas awgeed, sahayda korontadu si fudud ayey isu beddeli kartaa, waxaana hadda jira tiro aad u badan oo ah ilo koronto oo joogto ah, sida 12V iyo 24V darawallada LED. Nidaamiyaha toosan ayaa luminaya koronto badan, sidaas darteed iftiinku uma noqon karo mid iftiimaya sida ay u noqon karto koronto beddeleysa.

Sahayda beddelka waxtarka sare leh waxay si dabiici ah u horseedaa waxtarka iftiinka sare, taas oo ah waxa ugu muhiimsan codsiyada iftiinka badankooda. Sidoo kale, beddelidda sahayda korantadu way ka sii yaraanaysaa, waxay leedahay awood sare, waxayna xamili kartaa kor u kaca marka loo eego AC LEDs.

• Darawalada LED-ka ee goonida ah vs. Darawalada LED-ka ee Aan Go'doomin

Marka aan is barbar dhigno labadan shay, waxaan mid walba ugu yeernaa koronto beddeleysa. Marka loo eego qawaaniinta UL iyo CE, naqshadda go'doonsan waxay caadi ahaan ka shaqeysaa 4Vin + 2000V iyo 3750Vac, iyo tamarta wax-soo-saarka iyo soo-saarka ayaa si fiican u kala soocan. Isticmaalka transformer aad u dahaaran halkii aad ka isticmaali lahayd inductor-ka iyadoo qaybta wareejinaysa awoodda bini'aadamka ay ka dhigayso nidaamka mid badbaado leh. Sidaas oo ay tahay, waxa ay sidoo kale ka dhigaysaa mid tayo yar (5%) iyo ka qaalisan (50%). Dahaarka ayaa ka ilaaliya danab sare inuu ka soo galo wax soo saarka. Dhanka kale, nashqadaha lagu dhisay awoodda hoose waxay badanaa isticmaalaan naqshado aan go'doon ahayn.

• Voltage Joogtada ah vs. Dareewalka LED-ka Joogtada ah

Sababtoo ah LED-yadu waxay leeyihiin sifooyin VI gaar ah, waxay ku socotaa iyada oo aan la sheegin in isha joogtada ah ee hadda jirta ay tahay inay awood u yeelato. Si kastaba ha noqotee, darawalka korantada joogtada ah ee LED ayaa la isticmaali karaa haddii nidaamiye toosan ama iska caabin ah ay si isdaba joog ah ugu xiran yihiin LED si loo xaddido hadda. Calaamadaha iyo nalalka laydhka waxay inta badan adeegsadaan darawallada korantada joogtada ah ee LED-yada leh 12V, 24V, ama xitaa 48V sababtoo ah waxay aad uga waxtar badan yihiin darawallada LED-yada ee joogtada ah, kuwaas oo ah caadada iftiinka guud sida nalalka, nalalka toosan, nalalka hoose, nalalka waddooyinka, iwm. Ilaa inta wadarta wattage aysan dhaafin xadka korontada, xalka joogtada ah wuxuu u sahlayaa dadka isticmaala inay bedelaan qadarka iftiinka, taas oo siinaya dabacsanaan badan oo loogu talagalay rakibidda garoonka.

• Fasalka I vs. Class II LED Driver

Xaaladdan, I iyo II waxay ku qoran yihiin lambarrada Roomaanka halkii ay ka ahaan lahaayeen 1 iyo 2, taas oo macnaheedu yahay wax gebi ahaanba ka duwan, sida aad ku arki karto shayga xiga. Xeerarka IEC (International Electro-technical Commission) waxay adeegsadaan ereyada Class I iyo Class II si ay u qeexaan sida korontadu gudaha ugu dhisan tahay iyo sida ay korontadu ugu dahaaran tahay isticmaalayaasha inay ku dhacaan shoog koronto. IEC Si dadka looga ilaaliyo inay ka naxaan korontadu, Darawalada LED ee Class I waa inay lahaadaan isku xirka dhulka la ilaaliyo iyo dahaarka muhiimka ah. Looma baahna isku xirka dhulka la ilaaliyo (dhulka) sababtoo ah moodooyinka IEC Class II waxay leeyihiin astaamo badbaado oo dheeri ah sida dahaarka la xoojiyay. Darawalada fasalka I ee LED inta badan waxay leeyihiin xiriir dhulka ah marka la soo gelinayo, halka darawalada fasalka II aysan lahayn. Si kastaba ha ahaatee, darawalada fasalka II waxay leeyihiin heerar dahaar sare ah laga bilaabo gelinta ilaa xayndaabka ama soosaarka. Oo waa kuwan calaamadaha ugu caansan ee fasallada I iyo II.

• Fasalka 1 vs. Darawalka 2 ee LED

Nambarada Carabiga 1 iyo 2 waxay u taagan yihiin NEC (National Electric Code) fikradaha fasalka 1 iyo 2, siday u kala horreeyaan. Fikradahani waxay qeexayaan wax soo saarka korontada oo ka yar 60Vdc meel qalalan iyo 30Vdc meel qoyan, wax ka yar 5A hadda, iyo wax ka yar 100W, iyo sidoo kale shuruudaha faahfaahsan ee qaabka naqshadeynta wareegga. Isticmaalka darawallada fasalka 2 ee LED waxay leedahay faa'iidooyin badan. Wax soo saarkooda waxaa loo arkaa inuu yahay terminal badbaado leh, sidaa darteed ilaalin dheeraad ah loogama baahna qaybaha LED-ka ama qalabka nalka. Tani waxay lacag ku badbaadisaa tijaabinta dahaarka iyo badbaadada. UL1310 iyo UL8750 waxay dejiyeen shuruucda heerka 2 darawaliinta LED. Laakiin xadkan awgiis, Darawalka 2 LED wuxuu awood u leeyahay oo kaliya tiro cayiman oo LEDs ah.

• Dimmable vs. Darawalka LED-ka ee aan Dimmable

Waqtigan cusub, iftiin kasta waxaa loo sameeyaa inuu noqdo mid daciif ah. Tani waa mawduuc weyn sababtoo ah waxaa jira siyaabo badan oo loo yareeyo iftiinka. Aan mid walba markeeda ka hadalno.

1) 0-10V/1-10V Dimming LED Driver

2) PWM Dimming LED Driver

3) Triac madow Driver LED

4) DALI dhumid Driver LED

5) DMX yaraynta Driver LED

6) Hab-maamuusyada kale ee Darawalka LED

• Biyo-celiska vs. Darawalka LED-ka ee aan biyuhu celin

IEC 60529 waxay isticmaashaa IP (ilaalinta gudaha) shahaado sida kaliya ee lagu kala saari karo heerka ay darawallada LED ay biyuhu celin. Koodhka IP wuxuu ka kooban yahay laba lambar. Lambarka koowaad wuxuu ku qiimeeyaa ka-hortagga walxaha adag ee miisaanka min 0 (ilaaliyo la'aan) ilaa 6 (aan gelitaanka boodhka), lambarka labaadna wuxuu ku qiimeeyaa ilaalinta dareeraha miisaanka 0 (ilaaliyo la'aan) ilaa 7. (8) iyo 9) oo aan marar badan ku soo bixin ganacsiga iftiinka. Darawallada LED-ka ee leh qiimeynta IP20 ama ka hooseeya ayaa lagu isticmaalaa gudaha, halka darawallada biyuhu aysan bannaanka ku isticmaalin. Laakiin tani mar walba ma dhacdo. Tusaale ahaan, qaar ka mid ah codsiyada gudaha waxay isticmaalaan darawallada LED-yada ee aan biyuhu helin sababtoo ah waxay soo saari karaan awood aad uga badan kuwa IP-ga hooseeya iyaga oo aan u baahnayn nidaam qaboojin firfircoon, taas oo ka dhigaysa inay ka yar yihiin darawallada LED-ka ee IP.

Waa maxay Ballast iyo sababta aan loogu isticmaalin nalalka LED?

Markii nalalka iftiinka la sameeyay markii ugu horeysay, waxay lahaayeen farsamo gudaha dhexdooda ah. Shaqada shaygan waxay ahayd inay hoos u dhigto socodka korantada ee wareegga. Ballast waa shayga magaca. Haddii tan aan loo isticmaalin nalalka iftiinka iyo nalalka T8, weli waxaa jirtay fursad ah in koronto badan ay kor u kacdo (nalalka tuubooyinka). Ballast weli waxaa loo isticmaalaa nalalka iyo nalalka tuubada si looga ilaaliyo in hadda uu aad u sarreeyo. Ballasts ayaa sidoo kale inta badan loo adeegsadaa HID, halide birta ah, iyo nalalka uumiga meerkuriga.

• Ballast Magnetic 

Inductors, oo sidoo kale loo yaqaan ballasts magnetic, waxay siiyaan nalalka qaar xaaladaha korantada saxda ah si ay u bilaabaan oo u ordaan. U shaqee sidii transformer, oo bixisa koronto sax ah oo nadiif ah. Inkasta oo la sameeyay 1960-kii, haddana waxa la isticmaali jiray 1970-yadii ilaa 1990-kii. Waxaad ka heli kartaa iyaga oo ku jira laambadaha dareeraha-xoog-sare leh (HID), nalalka birta ah, laambadaha uumiga meerkuriga, nalalka dhaadheer, nalalka neon-ka, iyo wixii la mid ah. Kahor intaanay nalalka LED-yadu bilaabin inay beddelaan tignoolajiyadan ku dhawaad ​​2010, waxaa loo adeegsaday ku dhawaad ​​dhammaan baarkinnada muhiimka ah iyo nalalka waddooyinka ilaa 30 sano.

• Ballast koronto

Ballast koronto, wareeg ayaa loo isticmaalaa in lagu xaddido culeyska ama tirada hadda. Ballast elegtarooniga ahi waxa ay isku daydaa in ay socodka korantadu ka sii ahaato mid joogto ah oo sax ah marka loo eego kuwa birlabka ah. Dadku waxay bilaabeen isticmaalka kuwan in ka badan 1990-meeyadii, ilaa maantana waa la adeegsadaa. 

• Shaqada Ballast A 

Ballast-ku waxa uu koontaroolaa inta koronto tagta nalalka oo siiya koronto ku filan oo ay shitaan. Maadaama laambaddu aanay koontarool lahayn, waxay isticmaali karaan koronto aad u badan ama aad u yar kaligood. Ballastadu waxay hubisaa in xadiga korantada galaysa laambad aanu ka badnayn waxa tilmaamayaasha iftiinka u ogol yahay. Ballast la'aan, nalka ama nalka ayaa si dhakhso ah u soo jiidan doona koronto badan, taas oo ka bixi karta gacanta.

Marka ballastka la geliyo laambad, korontadu waa ay deggan tahay, ballast-kuna waxa ay koontaroolaysaa tamarta si aanay hadda u kicin xitaa marka nalalka ay ku xiran yihiin ilo awood sare leh.

• Maxay LED-yadu u isticmaalin Ballastka?

Nalalka LED-yadu uma baahna ballast dhowr sababood dartood. Marka hore, nalalka LED-ku ma isticmaalaan koronto badan. Sidoo kale, waxaad u baahan tahay beddelaha AC-ilaa-DC maadaama LED-yadu ay inta badan ku shaqeeyaan Direct Current (DC). Barafka waa in si toos ah loo xiraa marka loo bedelayo nalalka galleyda LED. Ugu dambeyntii, sababtoo ah LED-yadu aad ayey uga yar yihiin nalalka iyo nalalka tuubada, ma jirto meel dheeraad ah oo loogu talagalay ballast ay ku habboon tahay. Darawalada LED-ka ayaa laga dhigi karaa inay qaataan meel aad uga yar. Khubarada qaar ayaa sidoo kale u maleynaya in LED-yadu aysan u baahnayn ballast, ay isticmaalaan tamar yar waxayna bixiyaan iftiin badan.

• Ballasts vs. Darawalka LED

LED-ka iyo nalalka dhaadheer ma shaqayn karaan la'aanteed beddele u dhexeeya guluubka iyo isha korontada. Dhinac, nalalka caadiga ah ee shida ayaa kuleyliya fiil koronto leh si ay iftiin u sameeyaan. LEDs, dhanka kale, waxay adeegsadaan darawalada ledhka halkii ay ka isticmaali lahaayeen ballasts. Dareewalada iyo darawallada rasaasta waxay sameeyaan waxyaabo badan oo isku mid ah, markaa in la isku daro waa sahlan tahay.

Tan waxaa suurtageliyay ballasts fluorescent, kuwaas oo soo dira koronto-sare marka ay bilaabanto nolosha laambada. Mar alla markii nalka la shido, sareyntani waxay u shaqaysaa sidii nidaamiye hadda. Dareewalka korantada ee hogaaminta ayaa u beddela isha korantada mid gaar ah iyo hadda, taas oo markaa ka dhigaysa iftiinka LED-ka. Labaduba waxay ka ilaaliyaan iftiinka inuu saameeyo isha korontadu.

Darawalka LED ayaa loo baahan yahay si uu beddelka hadda u beddelo hadda tooska ah ee LED-yadu u baahan yihiin. Nalalka LED-yada si toos ah looguma shaqayn karo beddelka hadda jira, markaa darawalka LED ayaa looga baahan yahay inuu beddelo. Ballasts ayaa wax badan ka beddelay sida loo sameeyo iyo sida ay u adag yihiin. Ballasts-ku waxay ordi karaan nalalka fluorescent laakiin maaha LED-yada ama nalalka isticmaala tamar yar. Dhowr darawal oo LED ah ayaa u muuqdey inay soo saareen ballastadii. Sababtoo ah si ka sii fiican ayey u shaqeysaa, darawalka LED wuxuu sameyn karaa inta badan waxyaabaha uu ballastadu sameeyo.

Sidee Loo Isticmaalaa Darawalka LED?

Tilmaamaha dejinta Darawalada LED

1. Hubi in darawalka LED-ku uu la shaqeeyo labada nidaamka LED ee aad rabto inaad ku xidho iyo isha tamarta aad rabto inaad isticmaasho. Qiimaynta Amperage iyo Voltage-ka labaduba waa inay isku mid ahaadaan.
2. Hubi in darawalku aanu la tacaalin dhibaatooyinka deegaanka ka jira ee aan loo samayn in uu wax ka qabto. Tusaale ahaan, haddii aad rabto inaad dibadda u dhigto nalalka LED-yada, hubi in darawalku uu si fiican biyaha u xamili karo.
3. Markaad ogaato fiilooyinka togan iyo kuwa taban, waxaad ka bixi kartaa godkaaga shabagga.
4. Isticmaal boolal midabka saxda ah si aad darawalka ugu dhejiso nidaamka LED-ka.
5. Ku xidh fiilooyinka togan iyo kuwa taban ee nidaamka LED-ka si aad u hesho marinnada saxda ah ee darawalka.
6. Ku xidh terminalka goynta xadhigga cagaaran ee ka imanaya darawalka (GND).
7. Ku xidh fiilooyinka togan iyo kuwa taban ee godka korantada ilaa kuwa togan iyo kuwa taban ee darawalka.
8. Si taxadar leh u hubi rakibaadda si aad u hubiso in dhammaan isku xidhka ay adag yihiin oo ay ku yaalaan meesha saxda ah iyo in kulaylku aanu kor u kicin. Haddii ay wax qaldamaan, dami korontada oo ogaaw waxa khaldan.

Sidee Loo Dayactiraa Darawalka Iftiinka LED?

1. Awoodda shid.
2. Dareewalka ku fur furaha oo si taxadar leh u eeg nabarrada gubanaya iyo cilladaha kale ee ay fududahay in la arko.
3. Isticmaal qalabka baaritaanka korantada si aad u heshid qaybaha jajaban.
4. Haddii aad awooddo, dami qaybahan oo mar kale tijaabi qalabka. Haddii aan la samayn karin, darawalka oo dhan waa in la beddelaa.

Waxyaalaha ay tahay inaad tixgeliso ka hor inta aanad dooran darawalka LED-ka

• DC Dhimista

Ma jeclaan lahayd in LED-yadu ay dhalaal yar noqdaan? Mise waxaad qorsheyneysaa inaad bedesho sida uu u iftiimay? Ka dib dooro darawal dimmable ama koronto. Waa maxay sababtu? Ilaha korontadu way fududahay in la kala saaro sababtoo ah sida ay u shaqeeyaan. Shaxda qeexitaanku waxa kale oo uu leeyahay macluumaad dheeraad ah, sida noocyada kontaroolada dimmer ee loo isticmaali karo darawalada.

• Shuruudaha Awooda

Mid ka mid ah waxyaabaha ugu horreeya ee la tixgelinayo waa inta koronto ee laambadaadu u baahan tahay. Markaa, haddii LED-kaagu u baahan yahay 20 volts si uu u shaqeeyo, waa inaad soo iibsataa darawal 20-volt ah.

Marka la soo koobo, ujeedadu waa in la hubiyo in darawalkaagu uu helo qadarka saxda ah ee tamarta. Xeerka guud waa in aad shaqadaada ku qabato inta ay le'eg tahay iftiinka.

Darawalka korantada joogtada ah, waxa kale oo aad ka fikiri kartaa kala duwanaanshaha danabka. Laakin waxaad ku cabiri kartaa labada danab iyo kala duwanaanshaha hadda jira darawal joogto ah.

U fiirso inta danab ee iftiinka LED-ka ee la soo jeediyay uu isticmaali doono. Sidaa darteed, hubi in darawalka LED uu xakameyn karo korantada LED-ka. Sidan, way fududahay inaad hoos ugu degto tamarta wax soo saarka ee loo baahan yahay.

Sidoo kale, waa inaad ka fikirtaa watts. Inta lagu jiro habkan, hubi inaad soo iibsato darawal leh wattage ka sarreeya iftiinka.

• Awoodda Awooda

Cunsurka korontadu wuxuu caawiyaa go'aaminta inta awood ee uu darawalku ka isticmaalo shabakadda korontada. Kala duwanaanshuhuna waa inta badan -1 ilaa 1. Maadaama ay tani tahay kiiska, awoodda awoodda 0.9 ama ka badan ayaa ah heerka caadiga ah. Si kale haddii loo dhigo, marka nambarku u soo dhawaado hal, darawalku si fiican ayuu u shaqeeyaa.

• Ammaanka

Darawalada LED-kaaga waa inay la kulmaan heerar kala duwan oo dhowr ah. Tusaale ahaan, waxaanu leenahay UL fasalada 1 iyo 2. U isticmaal UL Class 1 darawalada soo saara koronto badan. Qalabka wuxuu u baahan yahay in si badbaado leh loogu diyaariyo darawaliinta kooxdan. Waxa kale oo ay hayn kartaa LED-yo badan, taas oo ka dhigaysa in ay si hufan u shaqeyso.

Heerka LED-yada, darawallada UL Class 2 uma baahna astaamo badan oo badbaado ah. Waxa kale oo ay la kulmeysaa halbeegyada ay dejisay UL1310. In kasta oo fasalkani uu ka badbaado badan yahay, waxa uu hal mar wada shaqayn karaa tiro cayiman oo LED-yada ah.

Qiimaynta IP waa hab kale oo lagu cabbiro badbaadada qafiska darawalku iyo waxa uu samayn karo. Haddii aad aragto IP67, tusaale ahaan, waxay la macno tahay in dareewalku uu ka badbaado boodhka iyo dhex-gelis kooban oo biyo ah.

• Karti

Qaybtani waa muhiim sababtoo ah waxay muujinaysaa inta awood ee darawalka LED u baahan yahay. Qiimaha waxa lagu muujiyay marka la eego boqolleyda. Markaa, waxaad filan kartaa inay shaqeyso inta u dhaxaysa 80% iyo 85% wakhtiga.

Faa'iidooyinka Darawalka LED-ka

Danab hoose oo ah 12 ilaa 24 volts koronto LEDs leh hadda toos ah. Marka, xitaa haddii danabkaaga AC uu sarreeyo, inta u dhaxaysa 120 iyo 277 volts, darawalka LED wuxuu bedeli doonaa jihada hadda. Si kale haddii loo dhigo, ka degista beddelka iyo toosinta hadda waa mid waxtar leh. Waxaad xitaa heli kartaa qadarka saxda ah ee tamarta sare iyo hoose.

Darawalada LED-yada waxay ka ilaalinayaan LED-yada inay ka badbaadaan isbeddelka danabka ama hadda. Haddii danabka LED-ka uu is beddelo, sahayda hadda ayaa isbedeli karta. Sababtaas awgeed, soo-saarka nalalka LED-ku waxay la xidhiidhaan inta ay le'eg yihiin. Nalalka LED-yada ayaa sidoo kale loo malaynayaa inay ku shaqeeyaan ilaa xad gaar ah. Sidaa darteed, hadda aad u yar ama aad u badan ayaa bedeli doona inta iftiinku soo baxayo ama waxay keenaysaa in LED-ku si dhakhso ah u jabo sababtoo ah aad ayuu u kululaadaa.

Guud ahaan, Darawalada LED waxay leeyihiin laba faa'iidooyin oo waaweyn:

1. Ka beddelashada AC una beddelo DC.
2. Darawaladu waxay caawiyaan hubinta in wareegga hadda jira ama danabku aanu hoos uga dhicin heerka la qiimeeyay.

Iftiinka Cusub Miyuu Lamid Yahay Dimming Cusub?

Ilaha iftiinka kale si degdeg ah ayaa loo damin karaa iyadoo la beddelo danabka, laakiin LED-yada waxa lagu demin karaa oo keliya iyadoo la beddelo saamiga danab ilaa hadda. Sababtan awgeed, waxaa jira siyaabo kala duwan oo loo yareeyo LED-yada:

• Iyada oo la adeegsanayo qaabaynta ballaca garaaca wadnaha (PWM) ama pulse duration modulation (PDM), qadarka wakhtiga tamarta la bixiyo waa la bedeli karaa (PDM). Si kastaba ha ahaatee, danab laftiisa isma beddelo. Si kale haddii loo dhigo, PWM waxay si dhakhso ah u dami kartaa LED-yada. Tani waxay dhacdaa in badan marka inta jeer ee uu ka sarreeyo 100 Hz. Maskaxdu waxay u malaynaysaa in qolku ka sii madoobaado sababtoo ah isha bini'aadamku ma sheegi karaan boodboodka inay dhacayaan ilaa ugu yaraan 75 Hz.

• Triacs iyo dimmers-ka xakamaynta wajiga ayaa markii hore loo sameeyay nalalka 60W, kuwaas oo bixiya qadar yar oo iftiin ah marka xagasha wajiga uu yahay 130 °. Dhanka kale, LED-yadu aad bay uga fiican yihiin waxayna isticmaalaan koronto aad u yar si ay u iftiimiyaan. Sababtaas awgeed, LED-yadu aad uma yaraa xagal wejiga ah 130°. Sidoo kale, xajinta hadda waxa laga yaabaa in aanay ku filnayn in triacku ku jiro xaalada korantada marka uu dhumucdiisu sarreeyo. Sababtaas awgeed, LED-yadu waxay bilaabaan inay liiqlaan. Weli, qaar ka mid ah darawallada LED-yada ayaa laga dhisay gudaha si ay uga gudbaan dhibaatadan.

• 1-10V: Habka 1-10V, ballasts iyo cutubyada kontoroolka waxaa ku xiran xariiqa koontarool ee laba-fire ah. Volt DC inta u dhaxaysa 1 iyo 10 volts ayaa loo isticmaalaa in lagu xakameeyo iftiinka, iyo marka uu korontadu kordho, sidaas oo kale iftiinka iftiinka.
