Abũbuwan amfãni da rashin amfani na COB kunshe-kunshe LED nuni allo da kuma ci gaban matsalolin

Tare da ci gaba da ci gaba da fasahar hasken wutar lantarki mai ƙarfi, COB (guntu a kan jirgi) fasahar marufi ta sami ƙarin kulawa.Kamar yadda tushen hasken COB yana da halaye na ƙarancin juriya na thermal, babban haɓakar haske mai haske, ƙarancin haske, da fitarwa iri ɗaya, an yi amfani da shi sosai a cikin na'urorin hasken gida da waje, kamar fitilar ƙasa, fitilar kwan fitila, bututu mai kyalli, fitilar titi, da fitilar masana'antu da ma'adinai.

Wannan takarda ya bayyana fa'idodin marufi na COB idan aka kwatanta da marufi na LED na gargajiya, galibi daga bangarori shida: fa'idodin ka'idar, fa'idodin ingantaccen masana'anta, fa'idodin juriya na ƙarancin zafi, fa'idodin ingancin haske, fa'idodin aikace-aikacen, da fa'idodin farashi, kuma ya bayyana matsalolin fasahar COB na yanzu. .

Bambance-bambance tsakanin marufi na COB da fakitin SMD

Fa'idodin ka'idar COB:

1. Zane da haɓakawa: ba tare da diamita na jikin fitila ɗaya ba, zai iya zama ƙarami a ka'idar;

2. Tsarin fasaha: rage farashin ƙwanƙwasa, sauƙaƙe tsarin masana'antu, rage juriya na thermal na guntu, da cimma marufi mai yawa;

3. Injiniya shigarwa: Daga gefen aikace-aikacen, COB LED nuni module zai iya samar da mafi dacewa da sauri shigarwa yadda ya dace ga masana'antun na nuni aikace-aikace gefen.

4. Halayen samfur:

(1) Ultra haske da bakin ciki: PCB allunan tare da kauri jere daga 0.4-1.2mm za a iya amfani da bisa ga ainihin bukatun abokan ciniki don rage nauyi zuwa akalla 1/3 na asali kayayyakin gargajiya, wanda zai iya muhimmanci rage tsarin. , sufuri da aikin injiniya farashin abokan ciniki.

(2) Juriya na karo da juriya na matsawa: samfuran COB suna ɗaukar kwakwalwan LED kai tsaye a cikin fitilun fitilu na allunan PCB, sa'an nan kuma haɗa su da ƙarfafa su da mannen guduro na epoxy.A farfajiyar fannoni an tashe shi zuwa farfajiya mai laushi, wanda yake mai santsi, mai wahala, tasiri mai jure da juriya.

(3) Babban kusurwar kallo: kusurwar kallo ya fi digiri 175, kusa da digiri 180, kuma yana da mafi kyawun tasirin hasken laka.

(4) Ƙarfin zafin zafi mai ƙarfi: samfuran COB suna ɗaukar fitilar akan PCB, kuma da sauri suna canja wurin zafin fitilar ta cikin foil ɗin jan karfe akan PCB.A jan karfe tsare kauri na PCB hukumar yana da m tsari bukatun.Tare da ƙari na tsarin saka zinari, ba zai haifar da raguwar haske mai tsanani ba.Saboda haka, akwai 'yan matattu fitilu, ƙwarai mika rayuwar LED nuni.

(5) Saka mai juriya, mai sauƙin tsaftacewa: santsi da wuyar wuri, tasiri mai juriya da lalacewa;Babu abin rufe fuska, kuma ana iya tsabtace ƙurar da ruwa ko zane.

(6) Duk kyawawan halaye na yanayi: ana karɓar maganin kariya sau uku, tare da ingantaccen ruwa mai hana ruwa, danshi, lalata, ƙura, wutar lantarki, iskar shaka da tasirin ultraviolet;Yana iya saduwa da duk-yanayin aiki yanayi, da kuma zafin jiki bambancin yanayi daga - 30℃ku – 80℃har yanzu ana iya amfani da shi kullum.

Gabatarwa zuwa Tsarin Marufi na COB

1. Abvantbuwan amfãni a cikin ingancin masana'antu

Tsarin samar da marufi na COB daidai yake da na SMD na gargajiya, kuma ingancin marufi na COB daidai yake da na marufi na SMD a cikin aiwatar da ingantaccen siyar waya.Dangane da rarrabawa, rabuwa, rarraba haske da marufi, ingantaccen marufi na COB ya fi na samfuran SMD.Kudin aiki da masana'anta na marufi na SMD na gargajiya sun kai kusan 15% na farashin kayan, yayin da aiki da farashin masana'anta na marufi na COB ke lissafin kusan 10% na farashin kayan.Tare da fakitin COB, farashin aiki da masana'antu za a iya adana su ta 5%.

2. Amfanin ƙananan juriya na thermal

Tsarin juriya na zafin jiki na aikace-aikacen marufi na SMD na gargajiya shine: guntu - m crystal m - solder hadin gwiwa - solder manna - jan karfe tsare - insulating Layer - aluminum.Juriya na thermal na tsarin marufi na COB shine: guntu - m crystal m - aluminum.Tsarin tsarin zafin jiki na kunshin COB ya fi ƙasa da na kayan gargajiya na SMD na gargajiya, wanda ke inganta rayuwar LED sosai.

3. Haske ingancin abũbuwan amfãni

A cikin marufi na SMD na gargajiya, ana liƙa na'urori masu hankali da yawa akan PCB don samar da abubuwan tushen hasken don aikace-aikacen LED a cikin nau'ikan faci.Wannan hanya tana da matsalolin haske tabo, haske da fatalwa.Kunshin COB wani kunshin haɗe ne, wanda shine tushen haske na saman.Ma'anar yana da girma kuma mai sauƙi don daidaitawa, yana rage asarar hasara na haske.

4. Amfanin aikace-aikace

Madogaran hasken COB yana kawar da tsarin hawa da sake dawo da siyar da kayan aiki a ƙarshen aikace-aikacen, yana rage yawan samarwa da tsarin samarwa a ƙarshen aikace-aikacen, kuma yana adana kayan aikin da suka dace.Farashin kayan aiki da masana'anta yana da ƙasa, kuma ingancin samarwa ya fi girma.

5. Amfanin farashi

Tare da COB haske Madogararsa, farashin dukan fitilar 1600lm makirci za a iya rage da 24.44%, da kudin da dukan fitilar 1800lm makirci za a iya rage da 29%, da kuma kudin da dukan fitilar 2000lm makirci za a iya rage da 32.37%

Yin amfani da tushen hasken COB yana da fa'idodi guda biyar akan amfani da tushen hasken fakitin SMD na gargajiya, wanda ke da babban fa'ida a cikin ingantaccen samar da tushen hasken, juriya na thermal, ingancin haske, aikace-aikace da farashi.Za'a iya rage ƙimar ƙima ta kusan 25%, kuma na'urar tana da sauƙi kuma mai dacewa don amfani, kuma tsari yana da sauƙi.

Kalubalen fasaha na COB na yanzu:

A halin yanzu, tarin masana'antu na COB da cikakkun bayanai yana buƙatar haɓakawa, kuma yana fuskantar wasu matsalolin fasaha.

1. Matsakaicin ƙimar farko na marufi yana da ƙasa, bambanci yana da ƙasa, kuma farashin kulawa yana da girma;

2. Daidaiton sa launi ya yi ƙasa da na allon nuni a bayan guntun SMD tare da rabuwar haske da launi.

3. Marufi na COB na yanzu yana amfani da guntu na yau da kullun, wanda ke buƙatar ingantaccen tsarin haɗin gwiwar kristal da waya.Sabili da haka, akwai matsaloli da yawa a cikin tsarin haɗin waya, kuma wahalar tsari ya bambanta da yankin kushin.

4. Farashin masana'anta: saboda ƙarancin ƙarancin ƙima, ƙimar masana'anta ya fi girma fiye da ƙaramin tazara na SMD.

Dangane da dalilan da ke sama, kodayake fasahar COB na yanzu ta sami wasu ci gaba a cikin filin nuni, ba yana nufin cewa fasahar SMD ta janye gaba ɗaya daga raguwa ba.A cikin filin da tazarar maki ya fi 1.0mm, fasahar marufi na SMD, tare da balagagge kuma barga aikin samfurin, babban aikin kasuwa da cikakken shigarwa da tsarin garanti, har yanzu shine jagorar jagora, kuma shine zaɓi mafi dacewa. shugabanci ga masu amfani da kasuwa.

Tare da haɓakawa a hankali na fasahar samfur na COB da haɓakar haɓakar buƙatun kasuwa, babban aikace-aikacen fasaha na fakitin COB zai nuna fa'idodin fasaha da ƙimarsa a cikin kewayon 0.5mm ~ 1.0mm.Don aron kalma daga masana'antar, "An tsara marufi na COB don 1.0mm da ƙasa".

MPLED na iya ba ku nunin LED na tsarin marufi na COB, da ST Pro jerin kayayyakin iya samar da irin wannan mafita. Allon nunin LED wanda aka kammala ta tsarin marufi na cob yana da ƙaramin tazara, mafi bayyananni kuma mafi ƙarancin hoton nuni.Ana tattara guntu mai fitar da haske kai tsaye a kan allon PCB, kuma ana tarwatsa zafin kai tsaye ta cikin allon.Ƙimar juriya na thermal yana da ƙananan, kuma zafin zafi ya fi karfi.Hasken saman yana fitar da haske.Kyau mafi kyau.
