Tam sim no cov xov xwm tsis zoo: PAR38 thiab PAR30 hais txog lub cev yam ntxwv ntawm qhov muag teev. PAR = Parabolic Aluminized Reflector, 38 = peb caug yim-yim yim yim ntawm ib nti, lossis 38*1/8 "= 4.75". Luas = 30 x 1/8" = 3.75" Raws li koj tau pom, PAB 38 muaj txoj kab uas hla loj dua li PAR 30 noob los yog tau.
Ua raws li qhov no, qhov par38 yog dab tsi?
PAB 38 yog ib hom halogen lossis LED teeb. Muaj ob lub ntsiab lus rau lub npe PAR, tab sis ob qho tib si piav tib yam nkaus. Ib qho yog parabolic aluminized reflector. Gas nyob rau hauv PAB 38 qhov muag teev rov tsim cov filament thiab tsim ib lub teeb uas siv tau ntev dua li ntau lwm hom teeb pom kev zoo halogen.
Kuj Paub, par30 yog dab tsi? Parabolic aluminized reflector (PAR) 30 qhov muag teeb tswj lub teeb ntau 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.
puas yog br30 tib yam li par38?
Piv txwv li, a BR30 yog 30/8ths ntawm ib nti los yog 30 muab faib los ntawm 8 uas sib npaug 3.75 nyob rau hauv txoj kab uas hla. Cov tib yam piv txwv siv rau a PAB 38 . Faib 38/8ths ntawm ib nti lossis 38 muab faib los ntawm 8 uas sib npaug 4.75 ″ hauv txoj kab uas hla.
Koj puas tuaj yeem siv par20 tsis yog par30?
PAR 20 yog ib tug me me reflector teeb nrog tsom teeb. Qee tus nyiam hu lawv lub teeb pom kev, tab sis qhov no yuav ua rau me ntsis yuam kev. Zoo li nws cov kwv tij loj PAR 30 thiab PAR38, nws tau tuaj nyob rau hauv ntau lub kaum sab xis ntawm qhov chaw nqaim mus rau qhov dej nyab loj. Qhov txawv ntawm qhov dej nyab PAR 20 thiab R20 yog txiav tawm ntawm lub teeb qauv.

Dab tsi yog qhov txawv ntawm qhov ua tau zoo thiab cov khoom lag luam teb thiab cov ntsiab lus ntawm kev lag luam uas txhua qhov ua haujlwm zoo tshaj?
Lub tuam txhab muaj peev xwm ua kom tau raws li cov neeg siv khoom xav tau raws sijhawm yog hu ua Kev Ua Haujlwm Zoo, thaum ua haujlwm tau zoo yog lub tuam txhab muaj peev xwm xa khoom raws li tus neeg siv khoom xav tau nrog tsawg kawg ntawm cov khoom siv raw, kev ua haujlwm thiab tus nqi
Dab tsi yog qhov txawv ntawm qhov point thiab nonpoint qhov chaw ntawm dej paug?
Piv txwv li, cov dej tso tawm los ntawm cov chaw tsim khoom lag luam ntawm qee yam lossis cov chaw kho dej khib nyiab. Cov chaw uas tsis yog cov ntsiab lus suav nrog kev khiav tawm ntawm thaj av ua liaj ua teb uas tuaj yeem ntxuav cov chiv lossis lwm yam tshuaj rau hauv pas dej lossis dej ntws - qhov no yuav tshwm sim ntau txhiab square kilometers
Qhov txawv ntawm par30 thiab br30 qhov muag teev yog dab tsi?
PAR30 qhov muag teev feem ntau yog siv nyob rau hauv ob qho tib si recessed teeb pom kev zoo fixtures thiab taug qab teeb pom kev zoo, yog li lawv tuaj nrog luv caj dab thiab ntev caj dab xaiv kom haum rau qhov kev pab no. PAR30 lub caj dab luv yog siv ntau dua hauv kev teeb pom kev zoo thaum lub caj dab ntev feem ntau siv hauv cov kaus poom teeb pom kev zoo. BR30 qhov muag teev tsis muaj qhov kev xaiv no
Dab tsi yog qhov txawv ntawm qhov cuam tshuam qhov (socket) thiab lub qhov (socket) pa?
Rau kuv qhov kev paub qhov sib txawv yog nqes mus rau cov khoom siv Qhov saum npoo-hardening ua rau muaj kev cuam tshuam cov qhov (socket) kom nqus tau qhov hloov pauv tam sim ntawd (aka 'kev cuam tshuam') zoo dua. Nrog rau kev cuam tshuam txaus txaus, lub qhov (socket) tsis tu ncua tuaj yeem tawm ntawm cov duab vim tias cov hlau siv muaj softer
Dab tsi yog qhov txawv ntawm qhov kev thov thiab qhov xav tau ntawm cov khoom hais tias mis nyuj?
Dab tsi yog qhov txawv ntawm qhov kev thov thiab qhov xav tau ntawm cov khoom, hais mis nyuj? Kev xav tau yog kev sib raug zoo ntawm ntau tus nqi thiab qhov xav tau ntawm cov nqi ntawd. Kev xav tau ntawm cov mis nyuj yog qhov kev sib raug zoo ntawm tus nqi sib txawv ntawm cov mis nyuj thiab qhov xav tau ntawm cov nqi ntawd
