• Epuka mabadiliko ya ghafla ya joto katika mazingira yenye unyevu mwingi, ili kuzuia umande.

6.3 Welding Process

Kanuni za Jumla:Weka umbali wa chini wa mm 3 kati ya mchomeo na taa ya epoxy.

Uchomeleaji wa Mikono:

• Joto la ncha ya chuma cha kuchomelea: hadi 300°C (inafaa kwa chuma cha kuchomelea chenye nguvu ya juu ya 30W).
• Muda wa kulehemu kwa kila pini: sekunde 3 kwa upeo.

Ulehemu wa wimbi (DIP):

• Joto la kuchochea: hadi 100°C (sekunde 60 kwa upeo).
• Joto na muda wa bakuli ya sindano: hadi 260°C, kwa sekunde 5.

Uangalizi muhimu wa kulehemu:

• Epuka kutumia mkazo kwenye pini katika halijoto ya juu.
• Usichome (kwa kuzamisha au kwa mkono) zaidi ya mara moja.
• Linda taa ya epoxy ya LED kutokana na mshtuko/mshtuko kabla ya kufikia joto la kawaida.
• Epuka kupoa haraka kutoka kwenye joto la kilele.
• Tumia joto la chini iwezekanavyo linaloweza kufanya mwunganisho wa kuaminika.

12. Maswali Yanayoulizwa Mara kwa Mara (Kulingana na Vigezo vya Kiufundi)

12.1 Ni mkondo gani wa kufanya kazi unaopendekezwa?

Tabia za optoelektroniki zimebainishwa chini ya hali ya IF=20mA, hii ndiyo hali ya kawaida ya majaribio na pia hatua ya kawaida ya uendeshaji inayopendekezwa kwa kufikia mwangaza na maisha maalum.

12.2 Je, naweza kuendesha LED hii kwa 25mA kwa mfululizo?

Ingawa 25mA ndio kiwango cha juu kabisa cha mkondo wa mfululizo, haipendekezi kwa uendeshaji wa kawaida. Kufanya kazi kwenye kiwango cha juu kabisa hupunguza ukingo wa usalama, kuongeza joto la kiungo, na kufupisha maisha ya kifaa. Kwa uaminifu bora, tengeneza kwa mkondo wa 20mA au chini.

12.3 Je, ninawezaje kufasiri thamani ya nguvu ya mwanga?

Kwa 20mA, nguvu ya kawaida ya mwanga ni milicandela 200 (mcd). Hii ni kipimo cha mwangaza unaohisiwa katika mwelekeo wa kilele cha utoaji. Thamani ya chini iliyohakikishwa ni 100 mcd. Thamani halisi ya kitengo maalum itaanguka ndani ya safu ya kiwango inayoonyeshwa na msimbo wa "CAT".

12.4 Pembe ya maana inamaanisha nini?

Pembe ya maana ya digrii 50 (FWHM) inamaanisha kuwa ndani ya pembe ya koni ya digrii 50 iliyozingatia kwenye mhimili wa LED, nguvu ya mwanga ni angalau nusu ya kilele chake. Mwanga unaweza kuonekana nje ya pembe hii, lakini kwa nguvu ndogo.

12.5 Is a heat sink required?

对于在中等环境温度下以20mA工作的单个LED，通常不需要专用散热片。然而，PCB上适当的热管理（足够的铜焊盘）是必要的。如果多个LED聚集在一起，或者环境温度较高（>~60°C），建议进行热分析并可能需要散热。

13. Uchambuzi wa Kesi ya Utumizi Halisi

Mazingira: Kiashiria cha Hali kwenye Router ya Mtandao

Mbuni anahitaji LED ya manjano nyangavu na ya kuaminika ili kuonyesha hali ya "Shughuli ya Muunganisho wa Intaneti" kwenye router ya kiwango cha watumiaji. LED itaendeshwa moja kwa moja na pini ya GPIO ya microcontroller ya 3.3V.

1. Uchaguzi wa Vipengele:LED hii ilichaguliwa kwa sababu ya mwangaza wake wa juu (kawaida 200 mcd), kuhakikisha inaonekana katika chumba chenye mwanga wa kutosha, na inalingana na viwango vya mazingira vinavyohitajika kwa bidhaa za kielektroniki za watumiaji.
2. Circuit Design:Calculate the current-limiting resistor. Using supply voltage V_supply= 3.3V, forward voltage V_f= 2.0V, operating current I_f= 20mA: R = (3.3V - 2.0V) / 0.020A = 65 ohms. Select the nearest standard value (68 ohms), resulting in a slightly lower current (approximately 19mA), which is acceptable.
3. Mpangilio wa PCB:LEDs are placed on the front panel. The PCB footprint matches the package dimensions. Small area copper pour connecting the cathode and anode pads aids in heat dissipation.
4. Assembly:LEDs are supplied in tape-and-reel format, compatible with the manufacturer's automated assembly line. Adjust the reflow soldering temperature profile to meet the specified requirement of 260°C peak temperature for 5 seconds.
5. Matokeo:Bidhaa ya mwisho ina kiashiria cha taa cha manjano kilicho wazi na sawasawa, kinachoonyesha hali ya mtandao kwa uaminifu, na kinakidhi mahitaji yote ya mwangaza na kanuni.

14. Introduction to Technical Principles

LED hii inategemea teknolojia ya semikondukta ya alumini-gali-indiamu-fosforasi (AlGaInP). Wakati voltage chanya inatumika kwenye kiunganishi p-n, elektroni na mashimo huingizwa kwenye eneo lenye ufanisi. Muunganiko wao hutoa nishati kwa njia ya fotoni (mwanga). Muundo maalum wa aloi ya AlGaInP huamua nishati ya pengo la bendi, ambayo inalingana moja kwa moja na urefu wa wimbi la mwanga unaotolewa (rangi). Katika mfano huu, muundo umerekebishwa ili kutoa fotoni katika eneo la wigo la manjano (takriban 589-591 nm). Kifuniko cha resini chenye kutawanyika cha manjano kinatumika kulinda chip ya semikondukta, kuunda boriti ya mwanga (inachangia kuunda pembe ya maono ya digrii 50), na kuongeza ufanisi wa uchimbaji wa mwanga wa chip.

• Uboreshaji wa Ufanisi:Maboresho ya kuendelea ya nyenzo na muundo yanalenga kutoa lumens zaidi kwa kila watt (ufanisi wa juu wa mwanga), na hivyo kupunguza matumizi ya nguvu kwa pato sawa la mwanga.
• Uboreshaji wa Ulinganifu wa Rangi:Maendeleo katika ukuaji wa epitaxial na mchakato wa binning yameleta usambazaji mkali zaidi wa urefu wa wimbi na nguvu, na hivyo kufanikisha usawa bora wa rangi katika safu.
• Kuimarishwa kwa Kudumu na Maisha:Msisitizo wa utafiti uko kwenye nyenzo na ufungaji ambao unaweza kudhibiti joto na kupinga mkazo wa mazingira vyema zaidi, na hivyo kufikia maisha marefu zaidi chini ya hali ngumu.
• Udogo:Msukumo wa vifaa vya elektroniki vidogo zaidi unachochea kupunguzwa kwa ukubwa wa ufungaji wa LED, huku ukidumisha au kuboresha utendaji wa macho.
• Ujumuishaji wa Akili:Mwelekeo mpana zaidi ni ujumuishaji wa moja kwa moja wa saketi za udhibiti, sensorer, au utendaji wa mawasiliano ndani ya ufungaji wa LED, kuelekea suluhisho za taa "zenye akili".
