LED Guddiga PCB tiknoolajigu wuxuu u horumaray waxyaabo badan oo cusub oo wax soo saar leh. Tusaale wanaagsan waa horumarinta PCBS ee nalalka LED. The LED is welded to the circuit board, and the chip produces light during the electrical connection. Weelka kuleylka iyo saldhigga dhoobada ayaa loo isticmaalaa in lagu xiro jajabka si loo nuugo kuleylka loona qaboojiyo geedi socodka.

Guddiyada PCB LED -ku waxay u muuqdaan inay soo saaraan kulayl badan, taas oo ka dhigaysa qaboojinta hab caadi ah oo hawl badan. Sidaa darteed, sida caadiga ah dooro guddiga wareegga korantada ee Core Core si loo hagaajiyo awoodda kala -daadinta kuleylka ee LED -ka. Gaar ahaan, aluminium waxaa caadi ahaan loo isticmaalaa in loo sameeyo guddiyada wareegga nalalka LED -ka. Aluminum PCBS typically include a thin layer of thermally conductive dielectric material that relocates and dissolves heat, providing excellent coherence compared to unyielding PCBS.

Codsiga PCB LED

Qalabka PCB LED -ga waxaa lagu dari karaa codsiyo badan oo nalal sababta oo ah wax -ku -oolnimadooda tamarta oo aad u fiican, qiime jaban iyo dabacsanaanta naqshadeynta ugu badan, sida:

Nalka taraafikada

Nalalka gaariga

Iftiiminta ciidanka

Street tunnel lighting

Runway -ga madaarka

Iftiinka laambadda waddooyinka

Iftiinka sawirka (qoraxda)

Tooshyada iyo laambadaha

Nalalka qolka qaliinka isbitaalka

Iftiin warshadeed iyo wixii la mid ah

RayMing wuxuu bixiyaa xalka nalalka LED ee hufan oo la awoodi karo

Xalka guddiyada wareegga LED -ka oo leh in ka badan toban sano oo waayo -aragnimo ah, waxaan awoodnaa inaan bixinno wax -soo -saarka guddiyada wareegga LED -ka, soo -uruurinta iyo isu -geynta qaybaha hal saqaf. Waxaan ku faraxsanahay inaan kula shaqeyno si aan u hormarino alwaaxyada aluminium/looxyada biraha ee codsigaaga gaarka ah. Waxaan bixinnaa looxyo FR-4 ah oo la awoodi karo oo leh dahaarka aluminium-kuleylka ah oo si hufan u kala firdhiya kuleylka, qaboojiya dhammaan qeybaha wareegga LED-ka si weynna u hagaajiya waxqabadka wax soo saarka.

Waa maxay gundhig PCB LED iyo sida ay u shaqayso?

Led waxay u taagan yihiin diod-yada iftiinka dhaliya (leds). Waxay yihiin diode semiconductor waxayna ka tirsan yihiin kooxda laambadda korontada, taas oo soo saarta iftiin iyada oo la isu geeyo lammaaneyaal lacag qaadeyaal ah oo ku jira semikonductor -ka oo leh farqiga kooxda ku habboon. Due to their low voltage, operating power, compact size, long life and stability, leds are used in both industrial and consumer markets. Mid ka mid ah astaamaha ugu soo jiidashada badan ayaa ah awoodda ay u leedahay in ay soo saarto iftiin iyada oo aan dhalin kulayl badan, taas oo ka dhigaysa mid ammaan u ah isticmaalka maalin kasta. Shaqayntiisu waa sababta ugu weyn ee leedyada loogu dhex daray guddiyada wareegga ee daabacan (PCBS). Led waa lagu kalsoonaan karo oo wax ku ool ah codsiyada PCB. Waxay u dhaqmaan sidii iftiin, gaar ahaan furayaasha filinka ee aan taaban. Looxyada isku dhafan ee LED -ka ayaa caadi ahaan loo adeegsadaa sawirrada polyester -ka iyo teebabka caagga.

Isku xirka isticmaalaha

Circuit boards are usually used for the lower circuitry of membrane switches, especially since they provide it. Display LED display window. Kuwani badiyaa way fududahay in lagu dhex daro naqshadaha wareegga wareegga wareegga daabacan, laakiin waxaa jira xulashooyin ku saabsan nooca LED -ka la isticmaalo.

Single point and block LEDS

They do the most and work the best of almost any type of surface material. Ogsoonow in dusha sare ee matte ama textured ka ah ayaa sida ugu wanaagsan loogu adeegsadaa faafinta iftiinka weyn. It is also important to remember that although leds cannot touch the active area of the switch, they can be made to believe they are part of the switch by graphical manipulation.

Isku-dhafan ama dusha sare ku rakiban hal dhibic LED

Hal dhibic oo isku dhafan ama caan ah LEDS ayaa lagu dhejin karaa giraanta hoose. Noocyada leedadka, midabyo kala duwan ayaa loo isticmaali karaa, oo ay ku jiraan leedh laba midab leh. Marka lakabka garaafyada loo qaabeeyo si loo helo LED, way fududahay in laga joojiyo joojinta isla isku xiraha. Ogsoonow inaadan u baahnayn inaad ku hayso shaxda dhammaystirka LED safka gooni ah.

Faa’iidooyinka isku dhafan PCB LED

Maaddaama qaybaha elektiroonigga ah ay noqdaan kuwo khafiif ah, adeegsiga furayaasha filimka LED -ga ayaa faa iido leh maadaama ay u oggolaanayso gaarsiinta badeecadda iyo isu -imaatinka ugu dambeeya. Kaararkan LED -ga ee isku dhafan ayaa ku habboon iftiiminta hooseysa, macaamilka, qalabka, aaladaha caafimaadka, warshadaha iftiinka ilaa dhexdhexaadka ah iyo qaar ka mid ah codsiyada badda iyo aerospace. Iyadoo aan loo eegin arjiga, faa’iidooyinka looxyada isku dhafan ee LED -ga ayaa badan:

Iftiin iyo indho la’aan

Beddelaad filim gadaal oo jaban

Iska ilaali boodhka iyo qoyaanka

Way fududahay in la dhexgeliyo cayaaraha is -dhexgalka ee adag

Isticmaalka tamarta hooseeya

Waxaa lagu heli karaa midabbo kala duwan, baaxad iyo xoog leh

Waxaa loo adeegsan karaa bilayska filinka lacagta ah ee dabacsan iyo furaha filimka naxaasta ah ee dabacsan

Haddii leedyada lagu daro guddiga wareegga, way fududahay in la isku daro furayaasha filinka khafiifka ah ee LED -ka leh furayaasha, shaashadaha taabashada iyo noocyada kale ee furayaasha filinka khafiifka ah. PCBS LED-ka la dhisay ama la dhexgeliyey waxay bixiyaan xorriyad naqshadeyn oo weyn xitaa marka la abuurayo qeybaha kala-beddelka gadaal ee adag. Dhumucda yar ee furayaasha filinka khafiifka ah ee LED -ku waxay yaraysaa aagga guud ee is -dhexyaalladan isku -beddelka adag. Designers and engineers often choose integrated LED PCBS when inspecting and updating products.

Guud ahaan, PCBS-yada LED-ku waxay siiyaan iftiinka ugu habboon ee isticmaalaha ee furayaasha filinka khafiifka ah. Mararka qaarkood waxay yihiin ikhtiyaar ka fiican dib -u -iftiiminta ICONS -ka yaryar iyo astaamaha maxaa yeelay iftiiminta labiska ee ICONS -ka weyn iyo astaamaha leh wareegyada PCB LED -ka ee la galiyay si fudud ma aha in la gaaro.
