akatungamirira Pcb bhodhi tekinoroji yakagadziridzwa kuita zvigadzirwa zvitsva zvakawanda. Muenzaniso wakanaka kukura kwePCB yemwenje ye LED. The LED is welded to the circuit board, and the chip produces light during the electrical connection. Iyo yekupisa singi uye ceramic base inoshandiswa kubatanidza iyo chip kuti ipinze kupisa uye kutonhodza maitiro.

Pcb akatungamirira ukomba anowanzoita vaunze yakawanda kupisa, izvo zvinoita kutonhora ne kwakajairika nzira kunonetsa. Naizvozvo, kazhinji sarudza wepfungwa Core LED wedunhu bhodhi yekuvandudza iyo kupisa kupisa kudzora kugona kwe LED. Kunyanya, aluminium inowanzo shandiswa kugadzira matunhu ematunhu emwenje ye 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.

Pcb akatungamirira kushanda

Pcb LED zvigadziri zvinogona kubatanidzwa mune akawanda mwenje kunyorera nekuda kwavo kugona kwesimba, yakachipa mutengo uye yakanyanya dhizaini dhizaini, senge:

Traffic mwenje

Misoro yemotokari

Kuvhenekera kwemauto

Street tunnel lighting

Nhandare yendege

Rambi remugwagwa

Photovoltaic (zuva) mwenje

Matochi nemarambi

Mwenje muchipatara chekuvhiya

Chiedza chemuchina uye zvichingodaro

RayMing inopa inoshanda uye isingadhuri LED mwenje mhinduro

Semhinduro yemabhodhi ematunhu e LED ane makore anopfuura gumi ane ruzivo, isu tinokwanisa kupa kugadzirwa kwemabhodhi ematunhu e LED, kutsvaga uye kuunganidza zvikamu pasi pedenga rimwe. Isu tinofara kushanda newe kukudziridza tsika aluminium / simbi mabhodhi kune yako chaiyo application. Isu tinopa anodhura akajairwa FR-4 mabhodhi ane thermal-aruminiyamu machira ayo anonyatsodzora kupisa, anotonhorera ese LED wedunhu zvinhu uye zvakanyanya kugadzirisa chigadzirwa kuita.

Chii chakabatanidzwa nePCB uye inoshanda sei?

Leds inomiririra mwenje-inoburitsa diode (leds). Iwo ari semiconductor diode uye ndeweboka remagetsi emagetsi, iro rinogadzira mwenje nekudzokororazve kwechaji yevatakuri vaviri vaviri mune semiconductors ine yakakodzera band gap. Due to their low voltage, operating power, compact size, long life and stability, leds are used in both industrial and consumer markets. Chimwe chezvinhu zvaro zvinokwezva kugona kwayo kuburitsa mwenje pasina kuburitsa yakawanda yekupisa, ichiita kuti ive yakachengeteka kushandiswa kwezuva nezuva. Kushanda kwaro ndicho chikonzero chikuru leds dzakabatanidzwa mumapuraneti edunhu (PCBS). Leds yakavimbika uye inoshanda kune PCB zvinoshandiswa. Ivo vanoita sechiedza, kunyanya mune isiri-yekubata mafirimu switch. Akabatanidzwa akatungamira emabhodhi anowanzo shandiswa kune polyester magiraidhi uye rabha mamaki.

Mushandisi wekushandisa

Circuit boards are usually used for the lower circuitry of membrane switches, especially since they provide it. Display LED display window. Izvi zvinowanzo kuve nyore kubatanidza mune yakadhindwa yedunhu bhodhi switch dhizaini, asi pane zvimwe sarudzo nezvekuti ndeupi rudzi rweLED yekushandisa.

Single point and block LEDS

They do the most and work the best of almost any type of surface material. Ziva kuti matte kana machira akaomeserwa anoshandiswa zvakanyanya kuwedzera kwakakura kwechiedza. 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.

Yakabatanidzwa kana yepamusoro-yakasungirirwa imwechete poindi LED

Yakabatanidzwa kana yakatanhamara imwechete poindi LEDS inogona kuiswa pane yakaderera mhete. Kune aya marudzi ematuru, mavara akasiyana anogona kushandiswa, kusanganisira maviri-mavara leds. Kana iyo giraidhi yakaumbwa kuti igamuchire iyo LED, zviri nyore kumisa kugumiswa kubva kumucheto kumwechete kwechibatanidza. Ziva kuti iwe haufanire kuchengeta iyo LED yekupedzisa chati mune yakasarudzika mutsara.

Makomborero akabatanidzwa akatungamirira PCB

Sezvo zvemagetsi zvigadzirwa zvadzikira, iko kushandiswa kweiyo LED firimu switch inobatsira sezvo ichibvumira nyore kugadzirwa kwechigadzirwa uye yekupedzisira gungano. Aya makadhi e LED akabatanidzwa anokodzera zvakanyanya kuvhenekera kwakaderera, mutengi, zvishandiso, zvigadzirwa zvekurapa, mwenje kune indasitiri yepakati uye zvimwe zvinoshandiswa zveMarine neaerospace. Kunyangwe iko kunyorera, zvakanakira zvakasanganiswa LED mabhodhi akawanda:

Chiedza uye chisingaoneki

Yakaderera mutengo backlit firimu chinja

Dzivisa guruva uye unyoro

Nyore kusanganisa kupinda yakaoma inowanikwa mitambo

Simba shoma rekushandisa

Inowanikwa mune akasiyana mavara, saizi uye simba

Inogona kushandiswa inochinjika sirivheri firimu chinja uye inochinjika mhangura firimu chinja

Kana ma leds akabatanidzwa mubhodhi redunhu, zviri nyore kusanganisa LED yakatetepa firimu switch nemabhobhobhoyo, bata mascreen uye mamwe marudzi eakaonda mafirita switch. Yakavakirwa-mukati kana yakaiswa mukati maPC PCBS inopa hukuru hwekugadzira rusununguko kunyangwe paunenge uchigadzira yakaoma backlit switch switch. Iyo diki ukobvu hwe LED yakatetepa firimu switch inodzora iyo yakazara nzvimbo yeaya akaomarara switch switch. Designers and engineers often choose integrated LED PCBS when inspecting and updating products.

Kazhinji, LED PCBS dzinopa yakanyanya mushandisi-inoshamwaridzika backlight kune yakatetepa-firimu switch. Dzimwe nguva ivo sarudzo iri nani yekuvhenekera padiki ICONS uye zviratidzo nekuti yunifomu kuvhenekesa kweakakura ICONS uye zviratidzo zvine zvakabatanidzwa zvePCB maseketi hazvisi nyore kuwana.
