Ib qho xoob xaim tuaj yeem ua rau muaj kev hloov pauv tam sim no los ntawm lub teeb, uas tuaj yeem tua tau teeb teeb nyob rau hauv cov hnub. Yog tias koj cov xov hlau nruj thiab koj lub fixture txuas zoo tsis tau koj teeb tseem tsis ua haujlwm, koj qhov teeb meem feem ntau nyob ntawm lwm qhov.

Hauv qhov no, vim li cas kuv lub teeb thiaj tuaj yeem hlawv tawm?

Tshav kub heev rau rov ua dua los yog npog teeb cov khoom siv, kev tsim cua sov ntau dhau ua tau ua rau qhov muag teev rau hlawv tawm . Qhov yooj yim kho yog hloov mus rau qis wattage qhov muag teev . Yog tias qhov no tsis ua haujlwm, koj yuav xav hloov mus rau cov khoom siv loj dua lossis siv lub ntiaj teb loj dua ntawm npog teeb fixtures, uas tso cai rau lub tshav kub dissipate.

Kuj Paub, puas khiav teeb pom kev tsis zoo? Nrog khiav teeb, peb teeb meem feem ntau: Teeb mus kiag li phem nrog lub suab "ping"; lub lampholder tuag tag tom qab xyoo tau ua haujlwm ncaj ncees; los yog tag nrho khiav , nrog rau tag nrho nws cov teeb, mus tsaus nti thiab nres ua haujlwm.

Hauv qhov no, vim li cas kuv lub teeb LED hlawv tawm sai heev?

Ib txwm ua xoob kev sib txuas, xws li ntawm lub qhov (socket) lossis nrog cov xaim sib txuas, tuaj yeem ua tau hlawv tawm lub teeb sai sai , raws li zoo raws li ua rau flickering. Cov kev sib txuas xoob no ua rau cov hluav taws xob tiv taus thiab cov cua sov dhau los ntawm cov ntsiab lus ntawm lub teeb, uas tuaj yeem ua rau nws lub neej luv.

Kuv yuav ua li cas thiaj paub yog tias kuv lub LED tau tawg?

Cov kauj ruam

  1. Yuav ib lub multimeter digital uas tuaj yeem nyeem cov diode.
  2. Nqa cov liab thiab dub coj mus kuaj.
  3. Tig lub multimeter hu rau qhov teeb tsa diode.
  4. Txuas cov dub sojntsuam mus rau cathode thiab liab sojntsuam rau anode.
  5. Txheeb xyuas tus nqi ntawm multimeter's digital display.
  6. Ntsuas qhov ci ntawm LED.
