• Chukua voltage ya juu ya mbele kutoka kwenye maelezo ya kiufundi (2.6V), ili kuhakikisha uendeshaji salama chini ya hali zote.Usimamizi wa joto:
• Ingawa matumizi ya nguvu ni ya chini, kudumisha joto la kiungo cha LED ndani ya mipaka yake iliyowekwa kunahakikisha uimara wa muda mrefu na pato la mwanga thabiti. Epuka kuweka LED karibu na vifaa vingine vinavyotoa joto.Reverse Voltage Protection:

Since this device is not designed for reverse bias, ensure the circuit design prevents any reverse voltage from being applied across the LED.

Optical Design:

• Pembea ya digrii 110 na lenzi ya kueneza nyeupe hutoa mwonekano wa taa mpana na sawasawa, unaofaa kwa viashiria vya paneli.9. Technical Comparison and Differentiation
• Ingawa kulinganisha moja kwa moja kunahitaji data maalum ya ushindani, kulingana na spec sheet yake, sifa muhimu za utofautishaji wa kifaa hiki ni pamoja na:Single package dual-color:
• Kuunganisha rangi mbili tofauti (manjano-kijani na machungwa) katika kifurushi cha kawaida cha kuingizwa moja kwa moja, inahifadhi nafasi ya PCB ikilinganishwa na kutumia LED mbili za rangi moja tofauti.Muundo wa msaada wa pembe ya kulia:
• Kifurushi cha nje chenye pembe ya kulia chenye rangi nyeusi kilichounganishwa hurahisisha usanikishaji na hutoa utendaji uliojengewa ndani wa kuimarisha tofauti, katika matumizi mengi bila haja ya mwongozo wa mwanga tofauti au spacers.AlInGaP Technology:

   Toa viwango tofauti vya nguvu ya mwanga na urefu wa wimbi kuu kwa kila rangi, kuruhusu mechi sahihi zaidi ya rangi na mwangaza katika matumizi muhimu._P10. Frequently Asked Questions (Based on Technical Parameters)_dSwali: Je, kuna tofauti gani kati ya urefu wa wimbi wa kilele na urefu wa wimbi kuu?
2. Jibu: Urefu wa wimbi wa kilele (λ
   ) ni urefu wa wimbi ambao nguvu ya mwanga inayotolewa ni ya juu zaidi. Urefu wa wimbi kuu (λ
3. Inatokana na viwianishi vya rangi, inawakilisha urefu wa wimbi moja unaolingana zaidi na hisia ya rangi ya jicho la binadamu. Wabunifu kwa kawaida hutumia urefu wa wimbi kuu kufafanua vipimo vya rangi.
   Swali: Je, naweza kuendesha LED hii kwa 20mA kama vile naendesha LED nyingi za kawaida?
4. Jibu: Kikomo cha juu kabisa cha sasa ya moja kwa moja ya mbele ni 20mA. Hata hivyo, sifa za umeme/optiki zimebainishwa kwa 10mA. Ili kuhakikisha utendakazi wa kuaminika kwa muda mrefu na kukaa ndani ya kikomo cha matumizi ya nguvu ya 52mW, inashauriwa kubuni sasa ya mbele kuwa 10mA au chini zaidi, kama ilivyotumiwa katika data ya vipimo.
   Swali: Kwa nini kiwango cha kikomo cha nguvu ya mwanga kina uvumilivu wa ±30%?
5. Jibu: Hii ni kwa kuzingatia utofauti wa mfumo wa kipimo wakati wa majaribio ya uzalishaji. Hii inamaanisha kifaa kilicho kwenye kikomo cha chini kabisa cha kiwango (k.m. 14 mcd) katika mfumo mmoja wa majaribio, kinaweza kupimwa kati ya takriban 9.8 mcd hadi 18.2 mcd kwenye mfumo mwingine uliosawazishwa. Mbuni wanapaswa kutumia thamani ya chini kabisa ya kiwango kwa hesabu ya mwangaza katika hali mbaya zaidi.
   Swali: Je, rangi tofauti zinapatikanaje?

Jibu: LED yenye rangi mbili ina chip mbili tofauti za semiconductor. Kutumia mkondo wa mbele kwenye seti moja ya pini kutawezesha chipi ya manjano-kijani kutokeza mwanga. Kutumia mkondo wa mbele kwenye seti nyingine ya pini (polarity sahihi) kutawezesha chipi ya machungwa kutokeza mwanga. Mzunguko lazima ubuniwe kudhibiti mkondo uendapo kupitia chipi inayofaa.

• Je, heatsink inahitajika?A: Kwa kuzingatia matumizi ya nguvu ya chini (hadi 52mW), katika matumizi mengi ndani ya anuwai maalum ya joto la uendeshaji, heatsink maalum kwa kawaida haihitajiki. Usanidi sahihi wa PCB na kuepuka nafasi zilizofungwa, zisizo na uingizaji hewa wa kutosha kwa kawaida yanatosha.
• 11. Mfano wa Matumizi HalisiPaneli ya hali ya Ruta ya Mtandao:
• Tumia LED ya manjano-kijani kuashiria "Umeme Wazi/Shughuli", na LED ya machungwa kuashiria "Kusubiri/Shughuli ya Data". Muundo wa pembe ya kulia huruhusu mwanga kutawanyika kwa upande, kwa kuonekana bora zaidi kwenye paneli.Sanduku ya Udhibiti wa Viwanda:

Tumia LED hii kwenye bodi ya udhibiti kama kiashiria cha hali nyingi. Kwa mfano, mwanga wa kudumu wa manjano-kijani unamaanisha "Mfumo Uko sawa", mwanga wa kuwaka na kuzima wa machungwa unamaanisha "Onyo", na rangi zinazobadilishana zinaashiria msimbo maalum wa hitilafu.

Vifaa vya sauti vya matumizi ya kawaida:

Tumia utendaji wake wa rangi mbili kuonyesha uteuzi wa chanzo cha ingizo kwenye paneli ya mbele ya eneo la kipengele kimoja (mfano, machungwa yanamaanisha "AUX", manjano-kijani yanamaanisha "Bluetooth").
