Guangmai Technology yog tus kws tshaj lij hauv kev ua lub zog siab LED tivthaiv 1W 3W Epistar Chip.
Lub ntsiab tsis ntawm LED
1 Forward voltage VF
Hais txog qhov hluav taws xob tsim tawm ntawm anode A thiab cathode K thaum muaj kev cuam tshuam tam sim no. Chav tsev yog V (Volt). Thaum qhov hluav taws xob mus rau tom ntej tsawg dua tus nqi (hu ua tus pib), tam sim no tsawg heev thiab tsis muaj lub teeb tso tawm. Thaum qhov hluav taws xob siab tshaj tus nqi tshwj xeeb, qhov tam sim no mus tom ntej nce nrawm nrog qhov hluav taws xob thiab tso tawm lub teeb. Yog tias qhov kev ua haujlwm ib txwm ua dhau los, LED yuav tawg. Feem ntau, qhov ib txwm muaj rau pem hauv ntej qhov hluav taws xob ntawm LEDs ntawm lub teeb pom kev sib txawv xim kuj txawv. Piv txwv li, lub teeb liab feem ntau yog nruab nrab ntawm 1.8V thiab 2.0V, thiab lub teeb xiav thiab lub teeb dawb yog nruab nrab ntawm 2.8V thiab 3.3V.
2 Forward tam sim no IF
Hais txog qhov tam sim no tsim tawm ntawm anode A thiab cathode K thaum muaj kev cuam tshuam tam sim no. Chav tsev yog A (ampere). Feem ntau, tam sim no rau pem hauv ntej ntawm LED yuav tsum tau tswj tsis pub dhau 20mA. Qhov tam sim no dhau los tuaj yeem yooj yim ua rau kev sib tshuam kub Tj ntawm P thiab N ntawm LED kom siab dhau, uas tuaj yeem ua rau LED puas lossis txo nws txoj haujlwm kev pab. Ib qho ntxiv, LEDs zoo li diodes zoo tib yam. Thaum qhov hluav taws xob nce ntxiv, qhov tam sim no yuav nce mus rau qhov loj, yog li feem ntau LED teeb-emitting diodes txuas nrog ua ke nrog tiv thaiv tiv thaiv.
3 Luminous siv IV
Qhia qhov ci ci pom los ntawm kev qhia tshwj xeeb. Chav tsev cd (candela, chav me me sib xws yog millicandela, uas yog, mcd), chav tsev ntawm lub kaum ntse ntse tso tawm thawj lub teeb ci ntsa iab hu ua candela. Ua tib zoo saib xyuas rau lub kaum taw tes thaum muab piv rau qhov pom kev. Lub teeb siv yog hais txog lub teeb pom kev zoo uas tau tso tawm hauv ib lub kaum ntse ntse. Raws li ib feem ntawm pob ntawv LED, lub lens tuaj yeem tsom lub teeb tawm hauv ib qho kev qhia tshwj xeeb (siv lub lens txhawm rau sau lub teeb), thiab tuaj yeem sau lub teeb txawm tias lub teeb pom kev tawm me me, yog li lub teeb pom kev loj dua. Nws yuav tsum tau taw qhia tias tus nqi IV feem ntau yuav tsum tau hais qhia ntau npaum li cas tam sim no yog tias LED ntsuas nyob hauv qab.
4 Luminous flux Φv [lm]
Hais txog tag nrho cov teeb pom kev tawm los ntawm lub teeb ci. Chav tsev yog lm (lumens).
5 Qhov tseem ceeb wavelength λD [nm]
LED feem ntau siv lub nthwv dej los qhia xim. Qhov tseem ceeb wavelength yog sib npaug rau qhov yoj yoj sib thooj rau cov xim pom los ntawm lub qhov muag, thiab sib txawv ntawm qhov siab tshaj plaws yoj yoj ntawm lub teeb ci ntsa iab, thiab chav nyob yog nm (nanometer).
Cov hauv qab no yog qhov tsis ntev ntawm qhov sib txawv ntawm cov xim ci ci LEDs:
Ple Ntshav: 400 ～ 435nm
■ Xiav: 435 ～ 480nm
■ Xiav thiab ntsuab: 480 ～ 500nm
■ Ntsuab: 500 ～ 560nm
■ Daj-ntsuab: 560 ～ 580nm
■ Daj: 580 ～ 595nm
Txiv kab ntxwv: 595 ～ 610nm
■ Liab: 610 ～ 760nm
■ Dawb, feem ntau qhia los ntawm cov xim hauv qab no. Lossis tsuas yog siv sov sov dawb, dawb huv, thiab txias dawb.
