LED PCB ibhodi ubuchwepheshe bukhule baba yimisha emisha yomkhiqizo emisha. Isibonelo esihle ukuthuthukiswa kwe-PCBS yokukhanyisa kwe-LED. The LED is welded to the circuit board, and the chip produces light during the electrical connection. Isinki yokushisa nesisekelo se-ceramic kusetshenziselwa ukuxhuma i-chip ukumunca ukushisa nokupholisa inqubo.

Amaphaneli e-PCB e-PCB athanda ukukhiqiza ukushisa okuningi, okwenza ukupholisa ngezindlela ezivamile kube nzima. Ngakho-ke, imvamisa ukhetha ibhodi lesifunda le-Core Core LED ukuthuthukisa ikhono lokusabalalisa ukushisa kwe-LED. Ikakhulu, i-aluminium ijwayele ukusetshenziselwa ukwenza amabhodi wesifunda amalambu e-LED. Aluminum PCBS typically include a thin layer of thermally conductive dielectric material that relocates and dissolves heat, providing excellent coherence compared to unyielding PCBS.

Isicelo se-PCB se-LED

Ukulungiswa kwe-PCB ye-PCB kungahlanganiswa ezinhlelweni eziningi zokukhanyisa ngenxa yokusebenza kahle kwamandla, izindleko eziphansi kanye nokuguquguquka kokuklama okuphezulu, okufana:

Isibani sethrafikhi

Izibani zemoto

Ukukhanyisa kwezempi

Street tunnel lighting

Umgwaqo wesikhumulo sezindiza

Isibani somgwaqo

Photovoltaic (solar) ukukhanyisa

Imibani namalambu

Lights in a hospital operating room

Ukukhanyisa kwefektri nokunye

I-RayMing inikeza izixazululo zokukhanyisa ze-LED ezisebenza kahle futhi ezingabizi

Njengesixazululo samabhodi wesifunda e-LED aneminyaka engaphezu kweyishumi yesipiliyoni, siyakwazi ukuhlinzeka ngokukhiqizwa kwamabhodi wesifunda e-LED, ukuthola nokuhlanganisa izinto ngaphansi kophahla olulodwa. Siyajabula ukusebenzisana nawe ukuthuthukisa amabhodi we-aluminium / wensimbi yangokwezifiso wohlelo lwakho oluthile. Sinikela ngamabhodi ajwayelekile we-FR-4 ashibhile anezingubo ezishisayo ze-aluminium eziqeda ukushisa kahle, zipholise zonke izingxenye zesekethe ze-LED futhi zikuthuthukise kakhulu ukusebenza komkhiqizo.

Yini i-PCB ye-LED efakiwe futhi isebenza kanjani?

Ama-Leds amele ama-diode akhipha ukukhanya (ama-leds). Zingama-semode e-semiconductor futhi angamalungu eqembu lesibani se-electroluminescent, elikhiqiza ukukhanya ngokuhlanganisa kabusha amaphaji wesithwali senkokhelo kuma-semiconductors anegebe lebhande elifanele. Due to their low voltage, operating power, compact size, long life and stability, leds are used in both industrial and consumer markets. Enye yezinto ezihehayo kakhulu yikhono layo lokukhiqiza ukukhanya ngaphandle kokwenza ukushisa okuningi, likwenze kuphephe ukusetshenziswa kwansuku zonke. Its functionality is the main reason leds are integrated into printed circuit boards (PCBS). Ama-Leds athembekile futhi ayasebenza ezinhlelweni ze-PCB. Zisebenza njengokukhanya, ikakhulukazi ekushintsheni kwefilimu okungathintwa. Amabhodi we-LED ahlanganisiwe asetshenziselwa imidwebo ye-polyester namakhibhodi enjoloba.

The user interface

Circuit boards are usually used for the lower circuitry of membrane switches, especially since they provide it. Display LED display window. These are usually easy to integrate into printed circuit board switch designs, but there are some choices about which type of LED to use.

Single point and block LEDS

They do the most and work the best of almost any type of surface material. Qaphela ukuthi i-matte noma i-textured surface isetshenziselwa kangcono ukusabalalisa ukukhanya okukhulu. 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.

Iphuzu elilodwa le-LED elihlanganisiwe noma elingaphezulu

I-LEDS ehlanganisiwe noma evelele eyodwa ingafakwa eringini eliphansi. Kulezi zinhlobo zama-leds, imibala ehlukile ingasetshenziswa, kufaka phakathi ama-leds anemibala emibili. Lapho ungqimba lwehluzo lwenzelwe ukuthola i-LED, kulula ukunqamula ukunqanyulwa kusuka ekugcineni okufanayo kwesixhumi. Qaphela ukuthi awudingi ukugcina ishadi lokuqedela i-LED kulayini ohlukile.

Izinzuzo ze-PCB ehlanganisiwe ye-LED

Njengoba izinto zikagesi ziba mncane, ukusetshenziswa kwama-switch e-LED kunenzuzo njengoba kuvumela ukulethwa komkhiqizo okulula nomhlangano wokugcina. Lawa makhadi e-LED ahlanganisiwe akulungele kangcono ukukhanyisa okuphansi, umthengi, imishini, amadivayisi wezokwelapha, umkhanyo okhanyisela izimboni eziphakathi kanye nezinhlelo ezithile zoLwandle nezasemkhathini. Ngaphandle kokufaka isicelo, izinzuzo zamabhodi we-LED ahlanganisiwe ziningi:

Ukukhanya nokungaqondakali

Izindleko eziphansi ezibuyisela emuva ifilimu switch

Melana nothuli nomswakama

Kulula ukuhlanganisa nemidlalo esibonakalayo eyinkimbinkimbi

Ukusetshenziswa okuphansi kwamandla

Kutholakala ngemibala ehlukahlukene, osayizi namandla

Ingasetshenziselwa ukushintshela ifilimu yesiliva nezimo zethusi nezimo zethusi

Uma ama-leds ahlanganiswe ebhodini lesifunda, kulula ukuhlanganisa ukushintshwa kwefilimu okuncane kwe-LED namakhibhodi, izikrini zokuthinta nezinye izinhlobo zokushintsha amafilimu amancane. Ama-PCBS we-LED akhelwe ngaphakathi noma ashumekiwe anikeza inkululeko enkulu yokuklama noma ngabe kwakhiwa izinto eziyinkimbinkimbi zokushintsha izinto. Ubukhulu obuncane bokushintshwa kwefilimu obuncane be-LED kunciphisa indawo ephelele yalezi zinhlanganisela zokushintsha eziyinkimbinkimbi. Designers and engineers often choose integrated LED PCBS when inspecting and updating products.

Ngokuvamile, ama-PCBS e-LED ahlinzeka ngokukhanya okusebenziseka kalula kakhulu kokushintshwa kwe-thin-film. Kwesinye isikhathi bayindlela engcono yokukhanyisa kabusha ama-ICONS amancane nezimpawu ngoba ukukhanya okufananayo kwama-ICONS amakhulu nezimpawu ezinamasekethe we-PCB ashumekiwe akulula ukufeza.
