PAB 38 yog hom halogen lossis LED teeb noob . Muaj ob lub ntsiab lus rau acronym PAR , tab sis ob leeg piav 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.
Hauv qhov no, qhov sib txawv ntawm par 30 thiab 38 yog dab tsi?
Tam sim no cov xov xwm phem: PAR38 thiab PAR 30 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". 30 = peb caug yim thib yim ntawm ib nti, lossis 30 * 1/8 "= 3.75" Raws li koj tuaj yeem pom, PAR38 muaj txoj kab uas hla ntau dua li a PAR 30 noob los yog tau.
Kuj Paub, qhov txawv ntawm par thiab BR qhov muag teev yog dab tsi? PAR sawv rau "parabolic aluminized reflector" thiab tau siv zoo tshaj plaws hauv qhov chaw uas xav tau kev tsom mus, nqaim nqaj ntawm lub teeb. Feem ntau PARs tsis pub dhau lub kaum sab xis ntawm 45 degrees feem ntau. BR sawv rau "bulged reflector" thiab suav tias yog lub teeb pom kev dav dav feem ntau tshaj 100-degree nqaj kaum.
Ib sab ntawm qhov no, PAR txhais li cas ntawm lub teeb?
Parabolic Aluminized Reflector
par 40 noob yog dab tsi?
PAR 20, 30, 38 ib BR (lossis R) 20, 30 thiab 40 txawm lawv lub npe zoo sib xws yeej txawv heev. PAR (luv rau Parabolic Aluminized Reflector) qhov muag teev yog cov teeb nrog "pom lub teeb" cov yam ntxwv, txhais tau tias lawv muab cov nqaj kis uas feem ntau qis dua 45 °.
