Koj yuav tsum paub tias cov lej txuas nrog no txhais li cas? PAB 20 : 20 txhais tau tias, qhov tseeb ntsuas los ntawm brim mus rau brim ntawm LED teeb , uas yog hais, 20/8 nti inch, kwv yees li 64mm; PAR 30 yog sawv rau 30 denotes, 30/8 nti nyob rau hauv ntev nyob ze rau 95mm, PAR38. 38 cim, 38/8 nti hauv qhov ntev, yog sib npaug rau 120mm.
Tsuas yog li ntawd, par30 txhais li cas ntawm lub teeb?
Parabolic aluminized reflector ( PIB) 30 qij tswj lub teeb kom meej dua. Lawv tsim txog plaub npaug ntawm cov teeb pom kev zoo ntawm cov kev pabcuam dav dav A duab incandescents, thiab siv nyob rau hauv recessed thiab taug qab teeb pom kev zoo. Zoo li txhua lub teeb pom kev zoo, 30 tus nqi nruab nrab yog txoj kab uas hla ntawm lub teeb 1⁄8 ntawm ib nti.
Ib tus kuj tseem yuav nug, qhov sib txawv ntawm par20 thiab r20 teeb yog dab tsi? Raws li qhov chaw no: R20 qhov muag teev muaj cov tsom iav uas coj lub teeb ncaj rau pem hauv ntej thiab tsim nqaim nqaim nqaj nqaj nqaj uas tsis meej dua PAR20 qhov muag teev . R20 qhov muag teev kuj tsim cov duab ntxoov ntxoo tsawg dua PAR20 qhov muag teev . PAR20 qhov muag teev tswj lub teeb kom raug thiab tsim lub teeb pom kev ntau dua R20.
Los ntawm qhov ntawd, qhov sib txawv ntawm par30 thiab par38 teeb yog dab tsi?
Tam sim no cov xov xwm tsis zoo: PAB 38 thiab PAR 30 hais txog cov yam ntxwv ntawm lub cev qhov muag teev . PAR = Parabolic Aluminized Reflector, 38 = peb caug yim yim ntawm ib nti, los yog 38 * 1/8 "= 4.75". Luas = 30 x 1/8" = 3.75" Raws li koj pom, PAB 38 muaj txoj kab uas hla loj dua ib PAR30 noob los yog ua tau.
Lub teeb par38 yog dab tsi?
PAB 38 yog hom halogen lossis LED lub teeb . Muaj ob lub ntsiab lus rau lub ntsiab lus PAR, tab sis ob qho tib si piav txog tib yam. Ib qho yog parabolic aluminized reflector. Cov pa hauv PAR 38 qhov muag teev rebuilds lub filament thiab tsim ib noob uas yog lub sijhawm ntev dua li ntau hom halogen teeb pom kev zoo.

Dab tsi yog qhov txawv ntawm qhov txias dawb thiab hnub ci LED qhov muag teev?
Cov xim ntawm lub teeb yog ntsuas los ntawm Kelvin (K) nplai. Piv txwv li, sov dawb LEDs yog 2700K txog 3200K, nruab hnub nrig yog nruab nrab ntawm 4000K txog 4500K, thiab txias dawb yog nyob nruab nrab ntawm 5000K txog 6200K
Qhov sib txawv ntawm lub teev thiab ASME propane tank yog dab tsi?
ASME tso tsheb hlau luam tau txais lawv lub npe los ntawm American Society of Engineers. ASME tso tsheb hlau luam raug ntsuas hauv nkas loos. Cov tank loj sib txawv ntawm 120 gallons txog 2,000 gallons. Lub peev xwm ntawm DOT thooj voos kheej kheej, yog ntsuas hauv phaus dej
Qhov txawv ntawm r20 thiab r30 qhov muag teeb yog dab tsi?
R20 yog R hom LED dej nyab ntau tshaj plaws uas koj tuaj yeem nrhiav tau hauv ntau lub tsev vim lawv tau siv los ua hluav taws xob los yog taug qab teeb pom kev zoo. R30 tsis tshua muaj vim tias nws yog tus qauv qub uas tau txais theem tawm vim tias nws tsis tshua muaj zog. Hloov chaw, nws tau hloov nrog BR30 LED teeb uas sib pauv tau
Dab tsi yog hom sib txawv ntawm LED teeb qhov muag teev?
E27 LED Qhov muag teev (ES) E14 LED Qhov muag teev (SES) B22 LED Qhov muag teev (bayonet) B15 LED Qhov muag teev (Me me Bayonet) GU10 LED Qhov muag teev. G4 LED Qhov muag teev. G9 LED Qij. MR16 LED Qij
Qhov txawv ntawm par30 thiab par30l yog dab tsi?
Qhov sib txawv ntawm dej nyab PAR30 thiab BR30 yog txiav tawm ntawm lub teeb pom kev zoo. Dej nyab PAR30 tuaj yeem muab lub dav nqaj kaum sab xis tab sis tsis ze li dav li BR30 thiab tseem nrog thaj chaw piav qhia ntau dua
