Chii chinonzi smd light strip chinorevei?

Nekuzivikanwa kwe "hapana chikuru mwenje mwenje" dhizaini dhizaini, LED mutsara mwenje mitsetse zvigadzirwa zviri kuramba zvichinyanya kufarirwa mukushongedza kwemba uye mapurojekiti ekugadzirisa imba yese. Kune matatu akajairwa ma LED anochinjika mwenje mitsetse zvigadzirwa pamusika, zvinoti SMD LED mwenje mitsetse, COB LED mwenje mitsetse uye yazvino CSP LED mwenje mitsetse. Kunyange zvazvo chigadzirwa chimwe nechimwe chine zvakanakira uye zvakasiyana, mupepeti anoedza kushandisa chinyorwa chimwe chete kuti unzwisise kusiyana kwevatatu, kuitira kuti iwe uite sarudzo yakarurama.

SMD mwenje mitsetse, iro zita rakazara reSurface Mounted Devices (Surface Mounted Devices) mwenje mitsetse, inoreva iyo LED chip iri kuiswa yakananga pane substrate yemwenje tambo, yobva yaiswa mukati kuti iite mitsetse yemarambi madiki. Rudzi urwu rwemwenje tambo imhando yakajairika ye LED mwenje tambo, iyo inowanzo ine hunhu hwekuchinjika, hutete, kuchengetedza simba, uye hupenyu hwakareba.

SMD ndiyo chidimbu che "Surface Mount Device", inova ndiyo yakajairika mhando ye LED mudziyo parizvino pamusika. Iyo LED chip yakavharirwa muiyo LED bracket shell ine phosphor glue yobva yaiswa pane inochinjika yakadhindwa yedunhu bhodhi (PCB). SMD LED mitsetse inonyanya kufarirwa nekuda kwekusiyana-siyana kwavo. , SMD LED zvishandiso zvinouya muhukuru hwakasiyana: 3528, 5050, 2835, 3014, 2216, 2110; ivo vanowanzodanwa maererano nekukura kwavo, semuenzaniso, saizi ye3528 i3.5 x 2.8mm, 5050 ndeye 5.0 x 5.0mm, uye 2835 ndeye 2.8 x 3.5mm, 3014 ndeye 3.0 x 1.4mm.

Sezvo akajairwa SMD LED inochinjika mwenje mitsetse inoshandisa yakaparadzana SMD LED zvikamu, chinhambwe / gaka pakati pezviviri zviri padyo ne LED zvishandiso zvakakura. Kana iyo mwenje tambo yakabatidzwa, unogona kuona ega ega anopenya mapoinzi. Vamwe vanhu vanoti Kunzvimbo dzinopisa kana kuti mapeji. Saka kana iwe usingade kuona zvinopisa kana mavara anopenya, unofanirwa kushandisa zvimwe zvekuvharisa (senge chivharo chepurasitiki) kuti uiise pamusoro peiyo SMD LED strip, uye iwe unofanirwa kusiya hurefu hwakakwana kuti chiedza chisanganise kucheka. iwo anopenya mavara Bright spot effect, saka ma profiles ealuminium anowanzo shandiswa akakora.

COB mwenje tambo, zita rakazara Chips On Board LED mwenje tambo, imhando ye LED mwenje tambo ine chip pabhodhi package (Chips Pabhodhi). Kuenzaniswa neSMD mwenje mitsetse, COB mwenje mitsetse yakananga kurongedza akawanda machipisi e LED pane redunhu bhodhi kuti igadzire yakakura-inoburitsa mwenje nzvimbo, iyo inowanzo shandiswa mukushandisa mamiriro anoda yunifomu mwenje.

Kutenda kune inoenderera mberi phosphor glue coating, COB LED mitsetse inogona kuburitsa yunifomu mwenje pasina yakanyatsojeka imwe mwenje nzvimbo, saka inogona kuburitsa yakaenzana inoburitsa mwenje nekuenderana kwakanaka pasina kudiwa kwekuwedzera mapurasitiki anovhara. , kana uchiri kuda kushandisa madhiri ealuminium, unogona kusarudza matete akatetepa aruminiyamu profiles.

CSP ndeimwe yeazvino matekinoroji muindasitiri ye LED. Muindasitiri ye LED, CSP inoreva iyo diki uye yakapusa pasuru fomu isina substrate kana waya yegoridhe. Yakasiyana neiyo SMD mwenje mitsetse yebhodhi tekinoroji, CSP inoshandisa inovandudza roll-to-roll FPC inochinjika edunhu mabhodhi.

FPC rudzi rutsva rwetambo yakagadzirwa ne insulating firimu uye yakanyanya kutetepa flat copper waya, iyo inotsikirirwa pamwechete kuburikidza neatomatiki laminating michina yekugadzira tambo. Iine zvakanakira kupfava, kupeta kwemahara uye kupeta, ukobvu hutete, hukuru hudiki, kunyatsojeka, uye kusimba kwakasimba.

Kuenzaniswa neyechinyakare SMD kurongedza, CSP kurongedza ine nzira iri nyore, isingadyike, yakaderera mutengo, uye mwenje-emitting angle uye gwara rakakura kupfuura mamwe mafomu ekurongedza. Nekuda kwekusarudzika kwemaitiro ayo ekurongedza, CSP mwenje mitsetse inogona kuve idiki, yakareruka uye yakareruka, uye iine madiki ekupeta kushushikana. Panguva imwecheteyo, kona yaro-emitting angle yakakura, inosvika 160 °, uye ruvara rwechiedza rwakachena uye rwakapfava, pasina mipendero yero. Chinhu chikuru cheCSP mwenje mitsetse ndechekuti haione chiedza uye yakapfava uye yakagomara.
