Kev Siv Lub Teeb Teeb

Qhov hloov pauv tam sim no hauv Suav teb yog 50Hz, thiab qhov ci ntsa iab ntawm cov roj teeb hloov pauv 100 zaug ib ob. Lub teeb hluav taws xob uas siv ncaj qha hloov tam sim no muaj flashing, thaum lub teeb incandescent muaj qhov flashing zaus ntawm 100 zaug hauv ib ob, uas yog ob zaug ntawm cov kab hluav taws xob.
Cov kev hloov pauv uas tib neeg lub qhov muag pom tau yog nyob rau hauv 30Hz, nrog 100 lub teeb hloov ib ob (los ntawm ci mus rau qhov tsaus ntuj, tom qab ntawd los ntawm tsaus mus rau ci, thiab lwm yam). Txawm hais tias peb yuav tsis pom lawv, qee qhov kev tshawb fawb qhia tias cov kev hloov pauv no (flicker) muaj kev cuam tshuam rau tib neeg lub qhov muag.
Yog lub teeb muaj zog ua rau tib neeg lub qhov muag, cov menyuam kawm ntawv yuav cog lus; Rau lub teeb qis, cov menyuam kawm ntawv yuav dilate.
Yog li ncaj qha siv lub teeb hluav taws xob AC tuaj yeem tsim teeb meem rau lub qhov muag (xav txog cov tub ntxhais kawm uas feem ntau siv lub teeb hluav taws xob nyeem phau ntawv). Ib tug neeg tau tsim lub teeb hluav taws xob siab, uas hloov ntau txhiab txhiab zaus hauv ib ob. Txij li thaum tib neeg lub qhov muag tsis muaj sij hawm hloov raws li thiab tsis tuaj yeem hnov ​​​​txog kev hloov pauv, nws tuaj yeem hais tias "tsis hloov", ua tiav lub hom phiaj ntawm kev tiv thaiv lub qhov muag. Hloov 50Hz AC zog zoo tib yam rau hauv high-frequency AC zog siv hluav taws xob zaus hloov dua siab tshiab. Nyob rau hauv high-frequency teeb, 50Hz AC zog yog thawj zaug hloov mus rau high-frequency AC zog, thiab ces high-frequency AC zog yog siv los teeb lub teeb.
Tab sis cov hluav taws xob hluav taws xob hluav taws xob ntawm cov hluav taws xob ntau zaus kuj yuav nce ntxiv, uas yog, hluav taws xob hluav taws xob hluav taws xob ntawm cov teeb hluav taws xob muaj zog ntau dua li cov teeb pom kev zoo tib yam thiab cov teeb fluorescent, uas tuaj yeem ua rau lwm hom kev puas tsuaj. Tsis tas li ntawd, high-frequency flashing tsis txhais hais tias tsis muaj flashing.
