R20 yog qhov feem ntau R hom dej nyab LED koj tuaj yeem pom hauv ntau lub tsev vim tias lawv tau siv los ua kom qis tuaj yeem ua hluav taws xob lossis teeb pom kev zoo. Cov R30 tsis tshua muaj vim nws yog ib qho qub tsim uas tau phased tawm vim nws tsis tshua muaj zog npaum. Hloov chaw, nws tau hloov nrog BR30 LED noob uas yog interchangeable.
Ib yam li ntawd, nws tau nug, dab tsi yog lub teeb r30?
Reflector (R) lossis Bulged Reflector (BR) 30 qhov muag teev muaj ib tug reflective txheej nyob rau hauv lub noob uas coj lub teeb rau pem hauv ntej. Zoo li txhua lub teeb qhov muag teev , tus nqi 30 sawv cev rau txoj kab uas hla noob nyob rau hauv 1⁄8 ntawm ib nti. Yog li ntawd, a R30 yog 3.75 nti diam.
Ib sab saum toj no, qhov sib txawv ntawm r30 thiab br30 yog dab tsi? Cov sib txawv tsuas yog txoj kab uas hla ntawm lub teeb. R30 qhov muag teev yog qhov loj ntawm ob qhov muag teev. BR30 Qhov muag teev yog qhov tseeb dua, muaj zog dua version ntawm R20 qhov muag teev thiab yog qhov loj tib yam li R20s. R30 qhov muag teev muaj txoj kab uas hla ntawm 3.75 ntiv tes, thaum BR30 qhov muag teev muaj lub cheeb ntawm 3.5 nti.
Tom qab ntawd, dab tsi yog r20 qhov muag teev?
R20 qhov muag teev muaj cov reflectors uas ncaj qha lub teeb rau pem hauv ntej thiab tsim ntau nqaim muag-edged beam uas tsis tshua muaj tseeb dua PAR20 qhov muag teev . R20 qhov muag teev kuj tsim cov duab ntxoov ntxoo tsawg dua PAR20 qhov muag teev . PAB 20 qhov muag teev tswj lub teeb kom raug thiab tsim lub teeb pom kev ntau dua R20.
Qhov txawv ntawm r20 thiab br20 yog dab tsi?
R20 tuaj yeem yog PAR20 lossis a BR20 . Lub ntsiab qhov sib txawv ntawm 2 yog lub kaum sab xis ntawm lub teeb. BRs kis lub teeb nrog 120 degree nqaj kaum sab xis, thaum PARs tsim lub teeb tsom nrog 40 degree nqaj kaum sab xis.

Dab tsi yog qhov sib txawv ntawm kev xa dej yaug thiab ntws thiab sau?
Kev xa dej ntws tawm tag nrho cov dej qub, cov dej qias neeg raug tshem tawm thiab hloov nrog cov kua dej tshiab, zoo siab. Coob leej neeg yuav sib cav tias kev yaug dej kom zoo dua li cov dej ntws tawm thiab rov ua dua vim tias cov kua dej qub tseem nyob hauv qhov kev sib kis tom qab hloov pauv, ua rau cov kua dej tsis huv tshiab, yog li, kev ua haujlwm qis
Dab tsi yog qhov txawv ntawm par20 thiab par30 qhov muag teev?
Koj yuav tsum paub tias cov lej txuas nrog no txhais li cas? PAR20: 20 txhais tau tias, qhov tseeb ntsuas los ntawm brim mus rau brim ntawm LED teeb, uas yog hais tias, 20/8 nti inch, kwv yees li 64 hli; PAR30 yog sawv cev rau 30 denotes, 30/8 nti ntev nyob ze rau 95mm, PAR38. 38 cim, 38/8 nti hauv qhov ntev, yog sib npaug rau 120mm
Dab tsi yog qhov sib txawv ntawm kev siv tas li thiab kev tsav tsheb cuam tshuam dab tsi?
Los ntawm kev sib piv, qhov cuam tshuam rau tus tsav tsheb tau nrawm dua thiab hnyav dua li tus qauv laum-tsav tsheb thiab feem ntau muaj lub zog ntau dua lossis sib zog. Cov txheej txheem xyaum ua haujlwm feem ntau yog siv rau qhov qhov drilling thiab tsav tsheb hauv cov khawm me me. Ib qho kev cuam tshuam rau tus tsav tsheb lub hom phiaj tseem ceeb yog kom tsav nrawm nrawm
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
Dab tsi yog qhov txawv ntawm nruab hnub khiav teeb thiab taws teeb?
DRLs yog lub teeb nyob rau pem hauv ntej ntawm lub tsheb uas nyob twj ywm thaum twg lub cav khiav. Tsis zoo li lub teeb taub hau, lub teeb thaum nruab hnub yog qhov tsaus ntuj thiab tsis teeb pom kev hauv ntej.
