3mm Kupfuura-gomba LED Tsvuku Yakapatsanurwa LED Yakakwira Kupenya

Tsvuku yakapararira LED ine yakajairwa chimiro & yakakwirira kupenya

Kana kupenya kwe3 0 4 R D kusingakwanise kusangana neyako inodikanwa, ndapota tarisa neiyi ； 304NRD.

Iri dzvuku kuburikidza-gomba reUS rakawana kupenya pamwero pane kupenya kwakakwirira, iri kumusoro zvishoma pane 304RD. Paunoshandisa iyi 3mm tsvuku kuburikidza-gomba reUS mu20mA, kupenya kunogona kusvika 200-400mcd. Ichave ingori 100-200mcd ye304RD. Enzanisa ne304R D, iyi 304NRD yakanyatso kukwana kushanda paiyo LED b ack mwenje chirongwa kana mwenje yekushongedza yeLED. Kana iwe uchitsvaga imwe 3mm LED ine kupenya kwakakwira, ndapota tarisa neiyi mwenje ye LED.

Kukura kwe3mm kuburikidza-gomba LED:

Kuburikidza-gomba akatungamira maficha.

* Divi reLens: 3mm;

* Wavelength 620-630nm;

* Lens mhando: Tsvuku yakapararira;

* Kuvimbika kwakakwirira uye kwakanyanya radiation kupisa;

Magetsi Parameter:

* Pulse kumberi zvazvino mamiriro: Duty 1% uye kupomba upamhi = 10us.

* Mamiriro ekumonerana: Mamiriro ekumonerana anofanira kupedzwa nema secongds matatu pa270 ℃

Electrucal Optical Hunhu (Tc = 25 ℃ )

* /1 / 2 iri off-sxis angle pane iyo inopenya intenity iri hafu yeaxia inopenya kusimba;

Chikumbiro chikuru:

* Yakanakira backlight;

* Chiedza mwenje;

* Akatungamira mwenje wekushongedza;

Kugadzira kufambira mberi kwe-kuburikidza-gomba LED:

Enzanisa neSMD LED, kuburikidza-gomba kugadzirwa kweUSD kuchanetsa. Zvinoreva kuti zvinotora yakawanda kugadzirwa kufambira mberi uye nguva yekugadzira:

Chekutanga pane zvese, isu tinofanirwa kugadzirira iyo LED chip (izvi zvichave zvakafanana neSMD LED kugadzirwa ); Kechipiri, isu tichafanirwa kuisa iyo LED chip mukati meiyo LED furemu, uyezve isu tichazoda iyo chaiyo yegoridhe waya yekubatanidza iyo cathode uye anode yeakatungamira furemu. Iko kunouya kwakasiyana, Kune SMD LED kugadzirwa, tinofanirwa kuisa epoxy kune LED furemu uye kumirira kusvikira yaoma neovheni. Nekudaro, kune eMarambi emwenje, isu tinofanirwa kubaya epoxy muchimiro che lens uye nekuisa zvinhu zvese kuhovhoni kweinenge maawa masere kusvikira vaoma. Mushure meizvozvo, isu tinofanirwa kuvabaya kubva muchoto uye tibudise iyo LED kubva muforoma. Uyezve isu tinofanirwa kucheka pini dze LED kuitira kuti zvive nyore kuyedza.

Pakupedzisira, isu takawana iyo LED. Kuti uve nechokwadi chehunhu uye yunifomu zvakanaka sekudikanwa. Isu tinodawo kuisa ese ma LED kumuchina wekuparadzanisa uye ivo isu tichawana iyo LED nemabhini akafanana.

Mamiriro Ekuchengetedza:

1. dzivisa kuenderera mberi nekuratidzira kune iyo condensing mwando nharaunda uye chengetedza icho chigadzirwa kure nekukurumidza shanduko mune ambient tembiricha;

2. Ma LED anofanirwa kuchengetwa aine tembiricha -30 ℃ uye hunyoro hushoma <60% ℃;

3. Chigadzirwa mupakeji yepakutanga yakavharidzirwa inokurudzirwa kuti iungane mukati maawa makumi manomwe nemaviri ekuvhura;

4. Chigadzirwa muhomwe yakavhurwa kweinopfuura vhiki chinofanira kubikwa kwemaawa matanhatu kusvika masere kusvika makumi masere kusvika masere p.

Akatungamirira KUWANDA nzira

1, Iyo lea d pani yeiyo LED inofanirwa kuenzana nekwakadzika kwemakomba anokwira paPCBP panguva yechikamu chekuisa ;

Kutungamira-kuumba kunogona kudikanwa kuti inisheni yekukwira namo inowirirana negomba pani ;

Tarisa mufananidzo uri pasi apa kuti utungamire nzira dzekutungamira .

Usatendese pcb inoteedzera munzvimbo yekubatana pakati peiyo leadframe uye iyo pcb kudzivirira pfupi-maseketi ;

Noted:

○ Yakarurama nzira yekumisikidza;

× Nzira isiriyo yekumisikidza;

2. Kana uchisanganisa waya kune iyo LED, yega waya yekubatana inofanirwa kuve yakasungirirwa yoga neyakaipisa-shrink chubhu kudzivirira pfupi-redunhu kusangana.

Usasunga tambo mbiri idzi mune imwe kupisa shrink chubhu kuti usapinze iyo LED inotungamira ;

Kunama kushushikana pane inotungamirwa lead kunogona kukuvadza zvemukati zvimiro uye kukonzera kutadza ;

Noted:

○ Yakarurama nzira yekumisikidza;

× Nzira isiriyo yekumisikidza;

3. Shandisa stand-offs (Fig 3) kana spacers (Fig 4) kuchengetedza zvakachengeteka iyo LED pamusoro pePCB ;

4. Chengetedza hushoma hwe3mm cl earance pakati pechigadziko cheiyo lens ye LED uye yekutanga lead bend (Fig. 5. Fig. 6)

5. Panguva yekuumba kwekutungamira, shandisa maturusi kana majegi ekubata zvinotungamira zvakachengetedzeka kuitira kuti simba rinobhenda risazotapurirwa kune lens yeLEM nezvivakwa zvemukati ;

Usaite lead inogadzira kana chinhu chacho chave kuiswa paPCB ;

L ead Maitiro Ekugadzira

1. Tungamira Kuumba Maitiro ;

2 . Usakotamisa zvinotungamira zvinopfuura kaviri (Fig. 7 );

3. Munguva yekunamatira, zvivharo zvezvikamu uye varidzi vanofanirwa kusiya clearance kuti vadzivise kuisa kusagadzikana kunokanganisa pane iyo LED panguva yekunamatira (Fig 8) ;

4. Iyo tipi yedare resimbi haifanire kubata iyo lens epoxy ;

5. Kuburikidza-gomba ma LED s haapindirani ne reflow soldering ;

6. Kana iyo LED ichizopindirwa zvakapetwa zvakapetwa kana kutarisana nemamwe maitiro uko chikamu chingaiswa pasi pekupisa kwakanyanya ndapota tarisa neBest LED kuti iwirirane .
