Nyob rau hauv kev sib piv nrog incandescent lub teeb qhov muag teev, neon xim teeb muaj ntau dua luminous ua tau zoo. Incandescence yog tshav kub -tsav lub teeb emission, yog li ib feem loj ntawm lub zog hluav taws xob muab tso rau hauv lub teeb incandescent tau hloov mus rau hauv tshav kub.

Ib qho ntxiv, puas neon teeb tau kub?

Neon zoo kawg nkaus muaj kev nyab xeeb rau qhov kov thiab yuav tsis hlawv koj. Thaum tsim thiab ntsia kom raug, neon xim tsuas yuav tau khiav sov . Cov electrodes uas txuas rau txhua daim ntawm neon xim tubing, uas tsim qhov pib thiab xaus rau qhov tam sim no mus ncig, ua kub thiab yuav tsum tsis txhob kov.

Ib yam li ntawd, cov cim neon tsim lub teeb pom kev li cas? A neon lub teeb muaj ib qho me me ntawm neon xim roj nyob hauv siab. Hluav taws xob muab lub zog rau strip electrons deb ntawm neon xim atoms, ionizing lawv. Ions tau nyiam mus rau qhov kawg ntawm lub teeb, ua kom tiav hluav taws xob Circuit Court. Teeb yog tsim tawm thaum twg neon xim atoms tau txais lub zog txaus los ua kev zoo siab.

Nyob rau hauv no, puas neon teeb muab hluav taws kub?

Nws yog hluav taws xob hloov mus rau tshav kub , lub zog poob rau inefficiency. Cov rhuab filament tsim cov electrons dawb, tsis zoo them-subatomic hais. Cov electrons no cuam tshuam nrog inert gas atoms dai nyob rau hauv lub teeb. Lawv luv luv yuam cov electrons hauv cov roj atoms rau hauv lub zog siab dua.

Dab tsi qhov hluav taws xob xav tau neon teeb?

Neon cov raj xav tau ib siab hluav taws xob ntawm qhov qis tam sim no ua haujlwm. Lub zog no tau muab los ntawm tus kws tshwj xeeb hloov pauv. Secondary hluav taws xob Feem ntau ntawm 1, 000 txog 15, 000 volts, thiab lwm yam tam sim no ntawm 20 mus rau 60 milliamps (thiab siab dua, rau txoj kab uas hla loj "txias cathode" tubing).
