Iyo LED skrini indasitiri yakaona kukura kukuru uye ikozvino yave kuonekwa seimwe yeakakosha uye anovimbisa zvikamu mumusika wepasi rose. Mwenje wemwenje we LED zvinhu zvakakosha mukatiLED skriniizvo zvinoita basa rakakosha mukuona kunaka kwezviratidziro. Kuti unzwisise zvizere mabheji emwenje e LED, zvakakosha kufunga nezvehuwandu mukati meindasitiri.
Saizi yemusika wepasi rose wemarambi e LED mabhedhi inofungidzirwa kukura ne9.6%, inosvika 240.9 miriyoni USD panosvika 2028, kubva 2022 mazinga. Uku kukura kwakakosha kunoratidza basa rakakosha rinoitwa nemarambi aya muindasitiri ye LED skrini.
Kana uri kuronga kuisa mari mukuratidzira kwe LED, kunzwisisa marambi e LED kwakakosha. Iva nechokwadi chekuongororawo marudzi akasiyana-siyana e LED mabhedhi aripo.
Chii chinonzi LED Mwenje Bead?
Kunzwisisa zvinorehwa nemarambi ndiro danho rekutanga pakuziva basa rinoitwa nezvikamu izvi mu LED skrini. Mwenje we LED mabhedhi, anozivikanwawo se LED machipisi kana emitters, ndiwo madiki semiconductors simba iroLED zvigadzirwakufanana ne LED kuratidza. Aya semiconductors anogonesa ma LED kuti abudise mwenje uye anowanzo gadzirwa kubva kuzvinhu zvakaita se:
- Arsenic
- Gario
- Phosphorus
Muvara unobudiswa ne LED unoenderana nechinhu chinoshandiswa mu semiconductor. Mavara akajairika anosanganisira tsvuku, yero, girini, uye bhuruu. Aya mabheji emwenje e LED ndiwo kiyi yekumusoro-inoshanda LED skrini. Dzinouya mumhando dzakasiyana, dzakadai se:
- Rectangle
- Square
- Round
- Lateral
- Micro
- Nzvimbo inopenya
Imwe neimwe bhedhi yemwenje ine maviri akabatana anowirirana nechaji yakanaka uye yakaipa mune semiconductor. Iyo anode inotakura chaji yakanaka, nepo cathode inotakura zvakaipa. Unogona kuziva izvi zviri nyore ne (+) uye (-) zviratidzo zvakadhindwa pazviri.
Mhando dze LED Bead Processing Methods
Mabhengi emwenje e LED anogadziriswa nenzira dzakasiyana-siyana, izvo zvinogona kukanganisa kuita kwavo uye mupiro kune kunaka kwezviratidziro zve LED. Kazhinji, iwo akaputirwa pamwe ne diffuser kana lens, achibvumira iyo semiconductor kudzora zvinhu zvakaita sekusimba uye kutungamira kwechiedza. Iwo mabhedhi emwenje e LED anowanzo kuisirwa paPCB (Yakadhindwa Circuit Board).
Inonyanya kuzivikanwa nzira dzekugadzira bhedhi dze LED iDIP (Direct In-line Package),SMD (Surface-mount Diodes),uyeCOB (Chip Pabhodhi). Imwe neimwe nzira ine zvayakanakira maererano nekuita, mutengo, uye kushandisa.
DIP (Yakananga In-line Package)
Iwo marambi emwenje e LED anoshandiswa muDIP nzira ari kuita mashoma mumusika uye iyo LED skrini indasitiri. Nekudaro, ivo vachiri kupa akati wandei mabhenefiti uye maitiro:
- Yakanakira kushandiswa kwekunze
- Kupenya kwepamusoro
- Excellent kugadzikana
- Diki yekuona angle range (H/V 120/60 madhigirii)
SMD (Surface-mount Diodes)
Iyo SMD yekugadzirisa nzira ndiyo inonyanya kufarirwa pakati peese ma LED mabhedhi nzira, kunyanya muindasitiri yekuratidzira ye LED. Mamwe maitiro akajairika eSMD anosanganisira:
- Easy uye nyore kugadzirisa
- Mutengo unoshanda
- Wide viewing angle (H/V 120/120 madhigirii)
- Inowanikwa mumadiki madiki
COB (Chip Pabhodhi)
Chekupedzisira, Chip Pabhodhi (COB) inoreva nzira yekugadzirisa iyo mabheji emwenje e LED anoiswa zvakananga pabhodhi redunhu, kusiyana neiyo yakajairika nzira inoiswa machipisi e LED pane socket. Iyi nzira inozivikanwa kune zvinotevera:
- Glop-top alias
- Insulation yakakodzera yechip
- Kudzivirirwa kwezvibatanidza zvayo
Hunhu hwe LED Mwenje Bead
Kana uchinzwisisa mabheji emwenje e LED, pane humwe hunhu hunowanzo zivikanwa machipi:
- Chip mutsara kuronga
- Huremu (yakaderera se 1 mg pa LED)
- Nzvimbo ine mhute
- Yakapfava skrini inopenya
- RGB dema kurongedza
Mwenje Wemwenje we LED vs. LED (Chiedza-emitting Diodes)
Mwenje wemwenje we LED uye ma-light-emitting diodes (LEDs) ane hukama asi akasiyana zvikamu, ane zvimwe zvakagovaniswa uye misiyano yakakosha. Heino kuenzanisa kwemaitiro avo:
| Hunhu | LED Mwenje Bead | Chiedza-emitting Diodes (LED) |
|---|---|---|
| Semiconductor | Ehe | Ehe |
| Charge | Positive | Positive |
| Voltage | Reverse breakdown | Reverse breakdown |
| Luminosity | Kubudirira kwepamusoro kunopenya | Kuderera kwekushanda |
| Magetsi Sensitivity | More sensitive kune current | Kusanyanya kunzwa kune ikozvino |
| Type of Installation | SMD | Plug-in |
Zvakanakira Kushandisa LED Mwenje Bead
Mabheji emwenje e LED anowanzoshandiswa mukuratidzira kwe LED nekuda kwezvizhinji zvakanaka zvavanopa. Hezvino zvimwe zvakanakira zvaungatarisira.
Micro-Spacing
Mabheji emwenje e LED anoshandiswa zvakanyanya mu micro-spacing LED splicing skrini, kunyanya kune zviratidziro zvinoda kupenya kwakanyanya uye kuita kusina musono. Aya mabhero akawana mukurumbira kune micro-spacingindoor LED skrini.
Kuenderana
Mwenje wemwenje we LED unopa kupenya kunoenderana, chena chiyero, uye chromaticity mazinga. Kusiyana nemamwe masikirini e LED anogona kuratidza kupenya kwakasiyana siyana kubva kumakona akasiyana, ayo anofambiswa nemarambi mabhero anochengetedza kufanana pakuratidzira.
Kuona Angle-Dependent
Paunenge uchisarudza mabheji emwenje e LED, kona yekuona chinhu chakakosha kufunga.Kunze kwe LED kuratidzainoda kona yakafara yekuona, saka mabhero anofanira kupa kupenya kwakadzikama kuti agone kuita ichi chinodiwa.
Size
Kukura kwechiratidzo che LED kunokonzerwa nekushandiswa kwemarambi emarambi. Iwo anonyanya kufanirwa kune madiki, emukati masikirini, achivaita akanakira seti inoda compact uye inonyatso ratidza.
Hupenyu hurefu
Zviratidziro zve LED zvinoshandisa mabheji emwenje zvakagadzirirwa kugara kwenguva refu kupfuura izvo zvine mamwe marudzi esemiconductors. Aya masikirini anogona kugara kusvika kumaawa e100,000, achipa kusimba uye simba nekuda kweiyo yakasimba PCB yekupisa chimiro.
Kukundikana Rate
Chiyero chekutadza mumaratidziro e LED ane mabheji emwenje zvakanyanya kuderera. Chirema chimwe muzviuru zvemapikisesi (tsvuku, girini, bhuruu) chinogona kukanganisa kuita kwese skrini, asi marambi mabhero anoderedza zvakanyanya njodzi iyi.
Anti-Static Mano
Mabheji emwenje e LED anozivikanwa neawo anti-static properties. Sezvo chiedza-emitting diodes ichinyanya kunetseka kune static magetsi, ivo vanowanzokundikana. Nekudaro, kupikisa kwemarambi kune static kunoderedza mukana wekutadza-kwane hukama muiyo LED skrini.
Maitiro ekuisa LED Mwenje Bead
Pakuisa mwenje we LED mabhedhi, zvakakosha kutevedzera matanho akakodzera. Iwe unogona kuvimba nenyanzvi kuti uise, asi kana uchida kuzviita iwe pachako, heino gwara rakareruka:
- Ziva mhando yemhando yemwenje ye LED bead yekugadzirisa nzira inoshandiswa.
- Ongorora waya ina inosanganisirwa muchigamba-mhando LED rambi.
- Maka nzvimbo dzakakosha pawaya (kazhinji pamamita) uye nyatsocheka panzvimbo dzakaiswa (Neimwe nzira, unogona kukumbira mabhedhi akafanochekwa kubva kumutengesi wako usati waendesa).
- Ongorora plug yekuisa uye bvisa chivharo chepurasitiki kubva papulagi.
- Batanidza mwenje wekuyedza, asi dzivisa kuivhara kana kuibatanidza zvakananga nekavha.
- Tanga kuiswa kwakakodzera nekuchengetedza socket yemwenje.
- Nyatsoisa iyo SMD LED rambi bead uchishandisa muswe plug uye clip.
Maitiro ekusarudza iyo Yakarurama LED Mwenje Mabheji
Kusarudza mabhero emwenje e LED kunosanganisira kufunga zvakati wandei zvinhu zvinokwanisa kuona kuti uchagutsikana here nesarudzo yako kana kuzvidemba. Kuti uve nechokwadi chekuti unoguma uine inoshanda uye yepamusoro-mhando yekuratidzira LED, heano mamwe akakosha matipi:
- Nyatsoteerera kune solder joints.
- Sarudza iyo yakagadzikana chip yekuvimbisa yemhando yepamusoro LED skrini.
- Ita shuwa kuti pamusoro pema LEDs akachena, haana mavara, uye mamwe matsvina.
- Tarisa kunaka kweglue rinoshandiswa mumabheji emwenje nekudzvanya paari (yakaderera-mhando glue inogona kukonzera kutsemuka kana deformation).
- Packaging tekinoroji inoita basa rakakosha mukuita kwemarambi ako e LED mabhero uye zviratidziro zvavanogadzira.
- Tenga chete zvigadzirwa kubva kune vanovimbika uye vakavimbika vatengesi.
Mhedziso
Kunzwisisa marambi emwenje e LED kungaite sekurema, asi kuziva zvikamu zvekuratidzira kwako kwe LED kunogona kukubatsira kusarudza zviratidziro zvemhando yepamusoro uye kushandisa zvakanyanya kugona kwavo. Aya mabhesi akabatana zvakanyanya ne LEDs, asi haasi iwo diode pachawo. Ndiwo ma semiconductors anosimbisa iyo yese LED skrini uye anogonesa ma diode kuburitsa mwenje.
Kana iwe usina chokwadi nezve kunyura zvakadzika mukati memwenje we LED mabheji, izvo zvakaringana. Ingoita shuwa kuti une nzwisiso yekutanga kwavari, saka kana yave nguva yekusarudza yako ma LED maratidziro, unogona kuyera zvakanakira nekuipira kwavo zvinobudirira.
