1. Qhib cov qhov hluav taws xob ntawm qhov hluav taws xob: siv 500W tungsten halogen teeb, 0 ~ 250V AC transformer, teeb qhov teeb yog teev rau 3.8 ~ 4.0 lab LUX, qhov kev ncua deb ntawm lub teeb thiab kev xeem ntawv yog li 15-20CM, thiab tus nqi ncaj qha yog qhov qhib hluav taws xob qhov hluav taws xob;
Thib ob, luv luv tam sim no: siv 500W tungsten halogen teeb, 0 ~ 250V AC transformer, teeb qhov teeb yog teev rau 3.8 ~ 4.0 lab LUX, qhov kev ncua deb ntawm lub teeb thiab kev xeem ntawv yog li 15-20CM, thiab qhov kev kuaj ntawd tus nqi yog luv-qhov tam sim no;
Qhov thib peb, qhov kev ua hauj lwm muaj zog: nrog 500W tungsten halogen teeb, 0 ~ 250V AC transformer, teeb qhov teeb yog teeb tsa 3.8 ~ 4.0 lab LUX, qhov kev ncua deb ntawm lub teeb thiab kev xeem ntawv yog li 15-20CM, thiab qhov zoo thiab tsis zoo ncej yog txuas nrog rau thaum uas tig mus. Kev ua haujlwm, (xam ntawm tus nqi ua haujlwm: R = U / I), qhov kev ntsuas tus nqi yog qhov ua haujlwm ua haujlwm;
4. Ua haujlwm tam sim no: siv 500W tungsten halogen teeb, 0 ~ 250V AC transformer, teeb qhov teeb yog teev rau 3.8 ~ 4.0 lab LUX, qhov kev ncua deb ntawm lub teeb thiab kev xeem ntawv yog li 15-20CM, nyob rau hauv series, (Calculation ntawm tus nqi ua: R = U / I), tus nqi kuaj yog tam sim no ua haujlwm;
Hnub ci tsis paub thiab kev paub txog
Lus Nug: Cov hnub ci ci puas ua kom muaj hluav taws xob nyob rau hauv cov pa taws los sis cov hluav taws xob?
A: Cov lus qhia meej yog tias nws tsim tawm ib qho me me tam sim no, uas tau hais tau tias yuav tsum tsis txhob poob siab.
