Chizindikiro LED pa dera la

Zosangalatsa kuona kudabwitsa liwiro taphunzira umisiri. zaka makumi atatu zapitazo, ife nakhuta kwathunthu ndi zamagetsi, amene ntchito, monga galimoto, kwinakwake kovuta, ndi otsika liwiro, wodzichepetsa nyumba popanda kukonzanso. Koma waika munthu amene nthawi zonse amayesetsa chinachake kwambiri wangwiro, ndipo tsopano pafupifupi gawo lililonse la moyo umamumvera wamakono zonse. Atakhudzidwa, ndondomekoyi komanso kusonyeza ndi machitidwe kuyatsa. Choncho tabwera zipangizo zapamwamba kwambiri michenga yopangira zida zamagetsi m'malo incandescent nyali - LEDs.

emitting Krustalo

Mbiri ya ntchito semiconductors akulu kuyamba ntchito nyale E-mtundu. AS Popov, amene amaonedwa anayambitsa wailesi, kufufuza mwa yosavuta michenga yopangira zida zamagetsi chipangizo, pamaso pa mphepo. Popov woyamba diode (chowunikira) wakhala anapanga kuchokera michenga yopangira zida zamagetsi Chip anakonza chofukizira, ndipo kasupe kukhudzana wa tungsten zisonga kapena zitsulo. kukhudzana Izi anadalira m'dera michenga yopangira zida zamagetsi, ndipo malinga ndi mfundo kukhudzana amapezeka bwino kwambiri chizindikiro transceiver.

Luso ndi timibulu ena kuti zimatulutsa kuwala pano anapeza kenako, mwangozi, koma nthawi yoyamba anali asanazolowere kuchita. Koma tsopano, LEDs ankagwiritsa ntchito zipangizo zina zapadera, ndipo tsiku ndi tsiku.

Kodi anatsogozedwa, momwe izo zikuwoneka pa tchati?

LED zosiyanasiyana otchedwa michenga yopangira zida zamagetsi mchitidwe wokhala ndi chikhalidwe cha galasi kuti zimatulutsa kuwala mchikakamizo cha magetsi inawadutsa m'kupita therethrough. Amenewa si semiconductors onse, koma okhawo pa zomwe m'kati recombination wa ma elekitironi ndi mabowo kutulutsidwa kwa mphamvu akupezeka osiyanasiyana kuwala. LED monga diode ochiritsira, ndi pn-mphambano napereka ziliri pa njira imodzi yokha.

Nkhani ina LEDs ngati kuwala emitting chipangizo ndi kuti adzamasulidwa mwachindunji kuwala quanta. Izi chimasiyanitsa izo nyali incandescent, lomwe limapezeka koyamba Kutentha mwauzimu ndi kutentha ena, kapena halogen nyali ndi gwero ionization. Mphamvu zomvetsa mu kuwala emitting diodes kupeza.

Amapanga, mu gawo lapansi kutsogozedwa ndi TACHIMATA ndi malo mibulu kwa mogwirizana ndi dera magetsi ndi nyumba, umene uli imodzi dongosolo kuwala. LED akuti mu chiwembu ali ndi ena likutipatsa mawu, pa bolodi pakompyuta iye amaimira munthu kabisidwe wapadera.

Kodi LED ndipo izi zimaonekera zokhudza ake pa tchati?

Anatsogolera limatulutsa kuwala, ichi ndi cholinga chake. Ndi zojambula za amasonyeza ndi mivi awiri akubwera kuchokera mchitidwe wa. Kugwiritsa ntchito chipangizo walandira waukulu kwambiri:

• Osiyana kudzionetsera. Pakuti kusonyeza kulolerana wa modes zosiyanasiyana zamakono ntchito zinthu zosiyana. gulu la zipangizo ntchito posonyeza digito, aliyense gawo LED atenge mbali ya manambala kapena zilembo. Chizindikiro LED pa dera la anaphatikiza m'gulu, sikudzakhala padera kwa aliyense, ndi gulu lonse chimaonetsedwa mawonekedwe a chizindikiro ndi nthambi ndi manambala a ojambula.
• Pakuti zogona, anthu ndi mafakitale kuyatsa.
• Monga mbali ya zowonetsera youlutsirapo panja, komanso kulenga scrolling malemba.
• The optocouplers. LED lakuti chithunzi mu nkhani iyi ndi wodzilemekeza ndi mchitidwe chithunzi photodetector.
• CHIKWANGWANI-chamawonedwe kachitidwe. Apa, LEDs zinthu monga radiators wa modulated yoweyula kuwala.
• Pounikira nsalu yotchinga madzi galasi.
• Kulengedwa ndi mafilimu.

Features zithunzi amanena kuti michenga yopangira zida zamagetsi ndi

Luso mfundo ndi malamulo amalamulira zoti ankatsogolera pa dera la. GOST 2.702-2011 n'kukulemberani:

• Amasonyeza kutsogozedwa ndi zinthu zina dera kudzera katundu zojambula, kapena mu mawonekedwe a pakompyuta. Pankhaniyi, njira otsiriza ndi Maganizo a osachepera 300dpi ndi zikuphatikizapo tif inalipo kapena bmp file.
• Inatsogolera ndi ntchito zojambula monga diode ochiritsira akachita bwalo. Pamwamba kumtunda lamanja la circumference wa imakonzedwa mivi kufanana awiri, anakafika ku membala m'munsi pa makona lamanja m'mwamba.
• LEDs pafupi amasonyeza alphanumeric malamulo zake zonse.
• Ziribe kanthu mmene LED pa dera, ndi polarity mu njira imodzi kapena wina kapena cham'mbali, malangizo a muvi amakhalabe sichinasinthe.
• The linanena bungwe akubwera kuchokera Triangles mu chithunzi amaimira anode (+) ndi ofukula mzere - ndi cathode (-).
• Ankatsogolera pa dera kuyenera siriyo yake chiwerengero. Manambala akupita kuchokera kumanzere kupita kumanja, pamwamba mpaka pansi.

LED - polarity chikhazikitso

LED chikhazikitso pa tchati zikhale zosavuta kudziwa polarity, koma kudziwa izo kwa item kumene anagula, muyenera kuyang'ana pa kukhudzana wake. Zabwino anode osachiritsika ambiri ali ndi kutalika kuposa cathode lapansi.

Ngati anatsogolera yakwera pa bolodi, ndi iye, pa zifukwa zosiyanasiyana, alibe zinthu chodetsa, ndi polarity wa michenga yopangira zida zamagetsi akhoza mtima, tione thupi lake. Kuchokera mbali ya cathode (zoipa osachiritsika) pa thupi ndi tayala mawonekedwe mphako. Komanso mandala mpanda mtundu anatsogolera anawona mkati ake. Kufanana chikho, mmene Chip michenga yopangira zida zamagetsi ili, ali kugwirizana kwa cathode lapansi.

Ngati kumene kuli kovuta kudziwa za polarity njira pamwamba, koma pali pamaso pa multimeter amagetsi, mukhoza kugwiritsa ntchito izo. Tengani diode wabwinobwino wa polarity kudziwika kupereka kupitiriza kwa chipangizo ntchito ndi kugwirizana kuti michenga yopangira zida zamagetsi lapansi. Kusunga pa polarity pamene diode amachititsa panopa. Anatsogolera chikugwirizana ndi chingwe schupam. Onetsetsani kuti amachita panopa, onani polarity.

The LED pa bolodi

Pamene kusindikizidwa dera bolodi msonkhano radiomontazhniki dongosolo yekha ndi mfundo za mndandanda wa zinthu. Malinga ndi mndandanda wa kulemba Akutsatira zizindikilo za mtundu manambala item ndi udindo pa dera la. Pali mfundo mayiko zizindikiro pa bolodi, omwe amagwiritsidwa ntchito zipangizo kunja.

The zoti bolodi LED ndi mu mawonekedwe a zithunzi fanizo weniweni kabisidwe ndi manambala. The kusonyezedwa yoyamba waukulu kumalo ozizira semiconductors, makalata amasonyeza mtundu chipangizo ndi chiwerengero - chiwerengero siriyo kuti chiwembu ndi mndandanda.

A kalembedwe mawonekedwe a LED matabwa dera ndi zofanana chifaniziro chake mwa chithunzicho, koma mwina muli circumference kuzungulira diode mafano. Enieni kabisidwe anachita likulu makalata - LED (kunja chiwembu) ndi HL (zoweta). chiwerengero akudza pambuyo makalata kapena pansi. Popanda chiwerengero kuli kovuta kudziwa magawo a michenga yopangira zida zamagetsi kuti gulu silimanena likuyesetsa osowa.

chodetsa LEDs

LED lettering pa chiwembu (chodetsa) ali zinthu zonse za makhalidwe a chipangizo makamaka michenga yopangira zida zamagetsi. Chodetsa muli zambiri ndithu otchulidwa, kotero si kuvala nyumba ndi kutsogolera dera kapena ma CD si soldered zinthu. LEDs ali matepiwo ali kumalo mu coils, amene kunyamula zizindikiro ankachita. Khalidwe kabisidwe akuganizira:

• A mndandanda wa katundu.
• Mtundu wa kuwala kutsogoleredwa. Modern kuwala emitting diodes mwayera, wobiriwira, wofiira, buluu, achikasu.
• Khalidwe la otaya mtundu. Mwachitsanzo, inatsogolera kuyatsa mu nyumba kapena pa msewu, zipangizo anaonetsa, kuunikira, chifukwa mawerengetsedwe fano.
• mtundu wa disolo. Pali kuwala kubalalika zida ndi cheza maganizo ndi ozungulira, chimaonekera ndipo opaque magalasi.
• Kuwala linanena bungwe.
• Kumwa mphamvu magetsi.
• Chiphaso malamulo a Mlengi. Ilibe katundu othandiza.
• malo zizindikiro. Opanga kuwasiya kwa kusinthidwa zotheka mbali.

Palibe muyeso enieni olemba a LEDs, moti aliyense wopanga ali kabisidwe yake. Kumbukirani sikutheka, koma opanga yaikulu ya mankhwala pa msika si kwambiri. Ena mwa iwo ndi makampani monga Philips, Cree ndi Samsung.

Pomaliza

Kuwonjezera LEDs ochiritsira ndi singano, apo SMD-LEDs ndi mapadi. Iwo ali wamfupi. Letter zoti LEDs a mtundu mu chiwembu zofanana ndi LED-zinthu, koma bolodi ndi chosavuta ndi zambiri okha kusonyeza polarity.
