SAVE LEDs, lossis lub teeb ci ntawm lub teeb hluav taws xob, tsis tshua muaj hluav taws xob, cov teeb hluav taws xob ncaj qha uas xav tau cov khoom siv hluav taws xob tshwj xeeb kom ua rau lawv cov teeb pom kev zoo thiab lub neej ntev. Tus qauv hluav taws xob qis hluav taws xob tsis zoo' t ua tau raws li qhov xav tau ntawm lub zog hluav taws xob ntawm LEDs tshwj tsis yog lawv hloov nrog cov txuas ntxiv thiab tswj cov khoom siv hluav taws xob. Thaum tus qauv hluav taws xob qis hluav taws xob hloov hluav taws xob muab hluav taws xob rau LEDs ncaj qha, cov LED yuav flicker, sib txawv hauv qhov ci ci thiab yuav ploj luminosity sai. Cov tsav tsheb LED suav nrog cov feem tshwj xeeb no, thiab lawv cov zis hluav taws xob txuam nrog qhov yuav tsum tau ntawm LED uas lawv muab.
DC Versus AC
Ntau cov LEDs tso hluav taws xob thaum muab hluav taws xob los ntawm hluav taws xob hluav taws xob tsawg. Txij li thaum lawv yog diodes ntxiv rau lub teeb ci, lawv kho qhov tseeb AC tam sim no, tshwj xeeb tshaj yog thaum muaj kev sib txuas hauv kev kho choj. Raws li diodes, lawv ua rau ib nrab nthwv dej ntawm AC khoom xa tuaj, thaum LED txuas nrog hauv kev coj rov qab hauv tus choj hloov ua lwm tus ib nrab yoj. Txhua LED tau txais lub zog rau tsuas yog ib nrab ntawm AC lub voj voog thiab yog tsaus rau lwm tus ib nrab, ua rau flicker. Cov tsav tsheb LED kho cov hluav taws xob AC tam sim no thiab muab DC lub zog uas yuav tsis ua rau muaj hluav taws xob LED.
Kev tsuj roj
LEDs rhiab heev rau kev hloov pauv ntawm qhov ntsuas voltage. Thaum qhov hluav taws xob thoob plaws ntawm LED ntau dhau, nws kos dhau mus tam sim no, txo nws txoj sia. Yog tias qhov hluav taws xob tsawg dhau, LED coj tawm tam sim no tsawg dhau thiab muab tua tsawg dua.
Cov hluav taws xob hluav taws xob qis muaj qhov nruab nrab sab hauv tsis kam. Cov tsis kam ntawm cov LED txuas rau lub tshuab hloov pauv nrog lub hnub nyoog thiab nrog rau kev ua haujlwm kub ntawm LED. Txawv LEDs tuaj yeem muaj ntau qhov sib txawv. Thaum lub tshuab hluav taws xob hloov cov hloov pauv ntawm nws qhov kev hloov kho sab hauv, qhov hluav taws xob nws xa mus rau qhov hloov pauv ntawm LED, thiab cov LEDs tsis ua haujlwm zoo ntxiv lawm. Cov tsav tsheb LED muab qhov ntsuas hluav taws xob tswj kom paub meej tias cov LEDs ib txwm khiav lag luam hauv lawv cov kev xaiv kom zoo.
Cov Kev Lom Zem Tam Sim No
Lub tshuab hluav taws xob tsawg hluav taws xob muab sib txawv ntawm cov hluav taws xob tam sim no thaum cov kab hluav taws xob rau ntawm cov tswv yim sab fluctuates lossis thaum muaj hluav taws xob fais fab. Cov LED loj tsaj rau qhov overcurrents thiab tuaj yeem kho kom kub sai thiab hlawv thaum lub sijhawm hloov pauv tam sim no. Cov tsav tsheb LED tswj qhov tam sim no kom paub tseeb tias nws qis qis dua qhov muaj phom sij rau cov LED. Txawm tias thaum qhov ntsuas hluav taws xob nce siab thaum lub zog nce, LED tsav tsheb kom qhov tam sim no los ntawm LED tas li.
Ntshe
Cov hluav taws xob hluav taws xob tsawg tuaj yeem' t dim LEDs. Rau cov teeb ci li niaj zaus, lub tshuab hloov khoom hluav taws xob tuaj yeem muab qhov hluav taws xob txo qis los ntawm kev hloov pauv tsis sib xws, xa cov hluav taws xob tsawg dua rau ntawm lub teeb ci. Rau LEDs, txawm tias qhov txo qis me me hauv qhov voltage ua rau txo ntau hauv cov teeb pom kev zoo. Lub ci ci ci LED tuaj yeem' t raug tswj kom raug nrog lub tshuab hluav taws xob tsawg.
Cov neeg tsav tsheb LED dim LEDs los ntawm kev xa cov puv, tswj tam sim no hauv luv luv. Rau tag nrho ntawm lub teeb, cov pulses khiav ua ke rau txoj kev tam sim no. Rau qhov dimming, lub pulses ua luv dua rau txo cov teeb ci tawm. Tus tsav tsheb tsav hluav taws xob tsim hluav taws xob (pulses) nyob rau ntawm qhov siab siab txaus kom cov LEDs tsis txhob' t zoo li flicker.
