Astaanta LED on Bannaanka

Interesting in la arko sida la yaab leh farsamooyinka kale ah xawaaraha. Soddon sanno ka hor, waxaan ahaayeen gebi ahaanba ku qanacsan ee korantada, taas oo loo isticmaalayo, kaliya gaari, meel xanibayo, iyo xawaaraha yar yahay, guryaha suubban oo aan dayactirka. Laakiin nin si dhisay in si joogto ah u dadaalaya wax ka kaamilsan, oo hadda ku dhow deegaan walba ee nolosha ku xiran yahay casriyeynta joogto ah. Taabtay, habka this ayaa sidoo kale soo bandhigi iyo nidaamyada iftiiminta. Sidaas daraaddeed, waxaan u timid inaad qalabka Semiconductor sare si uu u bedelo laambadihii incandescent - Kokes.

crystal emitting

Taariikhda isticmaalka semiconductors ka weyn bilaabin isticmaalka laambadihii nooca E. AS Popov, oo waxaa loo arkaa hindisa ee radio, Oo wuxuu baadhaa iyadoo adeegsanayo qalab Semiconductor fudud, joogitaanka hirarka raadiyaha. Popov diode hore (qalabka) ayaa lagu soo sameeyey chip Semiconductor go'an in haysta, iyo xiriirka guga ee tungsten a dhuuban ama bir ah. xiriir Tan waxaa isku hallaysay aagga Semiconductor ah, oo ku xiran barta xiriirka ee in laga helo transceiver signal ugu cad.

Awoodda kiristaalo gaar ah si ay u dhaadheer iftiin by hadda la helay ka dib, by fursad, laakiin markii ugu horeysay ee aan la isticmaali ee dhaqanka. Haddaba, si kastaba ha ahaatee, uu Kokes ku hubkaas ayaa loo isticmaalaa qalab gaar ah, oo nolol maalmeedka.

Waa maxay LED ah, sida ay u muuqataa on shaxda?

kala duwan LED yeedhay element Semiconductor isagoo singularity ah crystal si dhaadheer iftiin sarkhaansan ah therethrough maraayay korontada hadda. saamayn Tani ma aha at dhan semiconductors, laakiin kaliya kuwa at taas oo nidaamka of recombination of electrons iyo godad la sii daayo tamarta dhacdaa kala duwan ee indhaha. LED sida diode a caadiga ah, a pn-Isgoyska oo ag maraaba hadda hal dhinac oo kaliya.

feature A ee uu Kokes sida qalabka bixinaya laydh waa in la sii daayo quanta si toos ah iftiinka. Tani waxay kala ka laambadihii incandescent, taas oo dhacda muquuninta kululaynta ugu horeysay si heer kulka gaar ah, ama laambadahoodii halogeen leh saamayn ionization ah. khasaaraha Energy ee dioska- light-emitting hesho.

Qaab ahaan, in substrate LED waxaa lagu dahaarka leh kula a boosteejada crystal for xiriir si wareeg ah korontada iyo guryaha ah, oo isku mar uu yahay habka ay indhaha. Doorshadan LED in nidaamka ayaa ah hadal graphic gaar ah, sabuuradda elektaroonik ah uu muujinaysaa habaynteeda gaar ah.

Waa maxay LED, iyo sida ku muuqata in ay asaanay on shaxda?

LED iftiin shanqarta, tani waa ujeedada. Oo schematic waxaa si cad u tilmaamay by labada fallaadho soo socda ka element ah. Isticmaalka qalabka ayaa helay aad u ballaadhan,

• bandhig kala duwan. Waayo, digayaan mid noqoshada ee hababka kala duwan ee qalabka elektarooniga ah oo isticmaalaya xubno gaar ah. koox ka mid ah qalabka loo isticmaalo qaab digital, halkaas oo gabal kasta LED kaalin ee tirada ama warqado. Astaanta LED on Bannaanka ka mid ah kooxda, ma si gaar ah u noqon doonaa mid kasta, iyo kooxda oo dhan waxaa loo soo bandhigay qaab tilmaame la laan iyo tiriyey of xiriirada.
• Waayo, nalalka la deggan yahay, dadweynaha iyo warshadaha.
• Iyadoo qayb ka ah screens ee warbaahinta dibadda, iyo sidoo kale in la abuuro qoraalka boggan.
• optocouplers The. Jaantuska naqshada LED kiiskan waa la dhamaystirayaa element image photodetector ah.
• nidaamyada Fiber-optic. Halkan, Kokes ku dhaqmaan sida hiitarka of ruxruxo meyxaanahaa indhaha.
• Si aad u iftiimin shaashadda crystal dareere ah.
• Design iyo warshadaha madadaalada.

Features of sawirada u gudbiyo Semiconductor ah

heerarka Farsamada iyo xeerarka lagu maamulo magacaabista ah ee LED on Bannaanka. GOST 2.702-2011 qoray:

• Sawir LED iyo xubno kale circuit by hab oo sahay sawir, ama qaab elektaroonik ah. Xaaladdan oo kale, doorasho ee la soo dhaafay waa in xal ugu yaraan 300dpi oo ka mid ah tif kordhin ama file bmp.
• LED waa qaab schematic sida diode a caadiga ah ku lifaaqan ee goobada. Kor qaybta sare midig ee goobada ah waxaa lagu abaabulaa laba fallaadho isku midka ah, laga bilaabo xubin salka xagal u sii weynaydba midig.
• Kokes ku dhow ayaa tilmaamaya inuu code alphanumeric buuxa.
• Macna ma laha inta an LED on Bannaanka, la polarity ee hal jiho ama mid kale ama xagal, jihada fallaadhii isma badelin.
• wax soo saarka The soo socda ka saddexagal ee jaantuska ka dhigan anode ah (+) iyo khadka toosan - cathode ah (-).
• LED The on wareeg waa in ay tirada serial gaar ah. tiradoodii waxay ka bidix ilaa midig iyo kor ilaa hoos u dhaco.

LED - naqshada polarity

Doorshadan LED on shaxda wax fudud si loo ogaado polarity ah, laakiin si aad u ogaado ka item cusub ee iibsaday, waxaad u baahan tahay in aad eegto inuu xiriir. terminal anode Positive guud ahaan leeyahay dherer ka weyn cathode ah.

Haddii LED la dhajinta on guddiga, oo iyana waxay, sababo kasta oo, aan lahayn xubno sixitaanka, polarity ee Semiconductor waxaa go'aan looga gaari karo, aragti dhaw at jidhkiisa. Laga soo bilaabo dhinaca cathode ah (terminal negative) on jidhka leeyihiin qaab uruursanayey guri. Sidoo kale, nooca xero hufan keentay arkay ay gudaha. La mid ah koob uu ku jiray qori Semiconductor ku yaal, ayaa si toos ah xiriir in ay cathode ah.

In kiiska halkaas oo aanay suurtagal ahayn in loo ogaado polarity ka mid ah hababka kor ku xusan, laakiin waxaa jira joogitaanka multimeter elektaroonik ah, waad u isticmaali kartaa. Qaado diode caadiga ah ee polarity ogeysiiyo siiyo sii qalab qalliin iyo xirmaan Semiconductor ah. Kaydinta polarity marka diode ah ayaaba hadda. Keentay xiran schupam qiyaaseed. Hubi in ay qabtaan hadda, la soco polarity.

The LED on guddiga

Markii shirkii daabacay circuit guddiga radiomontazhniki nidaam u gaar ah iyo faahfaahinta of liiska xubno. Sida laga soo xigtay liiska this ee Calaamadayn la dabaqay muujinaysa nooca tirada iyo waxa jagooyinka on Bannaanka item. Waxaa jira heerarka calaamadaha caalamiga ah ee guddiga, kaas oo caadi ahaan loo isticmaalo in qalab laga keeno.

Doorshadan, guddida LED waa qaab images graphic, habaynteeda suugaan iyo lambarada. The qaab horeysay ee semiconductors ugu weyn ee kala horjeeda, warqado ayaa tilmaamaya nooca qalabka iyo tirada - tirada serial in nidaamka iyo in liiska.

sal A garaafyada u sameeyey looxyada circuit LED waa isku mid ay image ee sawirka, laakiin waxaa laga yaabaa in aanay ku goobada ku wareegsan icon diode ah. The warqado suugaan habaynteeda sameeyaa magaalada - LED (nidaamka laga keeno) iyo HL (qoyska). Tirada timid ka dib markii warqado ama hooseysa. Aan tiro lahayn waa wax aan macquul aheyn in ay go'aan ka soo koobin ee Semiconductor in guddiga ma tilmaamayso laga reebo dhif ah.

sixitaanka Kokes

Ereyada LED on nidaamka (sixitaanka) ayaa dhammaan macluumaadka ku saabsan dabeecadaha qalabka Semiconductor gaar ah. Calaamadaynta jira waxyaabo badan oo characters arrin, sidaa daraadeed waxa aan la gelin ah oo ku saabsan guryaha iyo waxa rasaasta ah soo wareegi jiray ama baakada aan soldered xubno. Kokes ku jira cajalado waa talgaley ee gariiradda, oo waxaad dhali doontaa Calaamooyinka sixitaanka. Deji Character ka tarjumaysaa:

• taxane ah oo wax soo saarka.
• Midabka iftiinka LED ah. dioska- light-emitting Modern waa cadaan, cagaaran, oo cas, iyo buluug, orange, huruud ah.
• Tayada socodka midabka. Tusaale ahaan, nalalka LED ee guriga ama waddada, qalabka bandhigay, nalal, waayo matrices image.
• nooca la gashto. Waxaa jira alaabtii light-jejebinta iyo shucaac ah diirada la lenses domed, hufan iyo Doolaal.
• saarka Light.
• Isticmaalka awoodda korontada.
• code aqoonsiga ee soo saaraha. Waxay leedahay ma load ku ool ah.
• Calaamooyinka reserve. Soo-saareyaasha ayaa u daysaan habeyn suurto galka ah ee xubno ka ah.

Ma jiro Heerka gaar ah lagu calaamadiyey ee uu Kokes, sidaas saaraha kasta waxay leedahay habaynteeda u gaar ah. Xusuusnow, ma suurtowdo, laakiin saarayaasha ugu waaweyn ee wax soo saarka this suuqa ma aha oo aad u badan. ka mid ah shirkadaha sida Philips, Kirii iyo Samsung.

gunaanad

Waxa intaa dheer in uu Kokes caadiga ah la pin a, waxaa smd-Kokes la pads. Waxay yaryar ee size yihiin. Doorshadan Letter of Kokes nooca in Scheme isku la LED-cunsur, laakiin guddiga waa la fududeeyay oo sida caadiga ah ku koobnayn oo muujinaysa polarity ah.
