Shenhai Explosion-Proof
Txhua tivthaiv ntawm ib yam khoom yuav muaj feem rau nws lifespan, Li ntawd, nws tseem ceeb heev tias tag nrho qhov chaw hauv ib lub teeb fixture yog zoo los tiv thaiv ntau yam teeb meem. Muaj coob tus neeg muas zaub uas nquag deal nrog teeb fixtures yuav muaj ces yuav tsum ces yuav tsum no scenario: Tus LED tawg-pov thawj teeb tsis xa rau. Dab tsi yuav ua tau qhov no? Wb tshawb ua ke hnub no!
Electrostatic Discharge (ESD):
Tus LED nti yuav raug kev puas tsuaj vim electrostatic discharge, rendering lub PN junction ineffective thiab ua leakage tam sim no, yeej tseem zoo xa nws mus rau hauv ib resistor. Tiv thaiv ESD puas rau electronic components yog ib tug tseem ceeb heev ua hauj lwm hauv txoj kev ua lag luam electronics. Tej qhov teeb meem ntawm tej theem yuav ua teeb meem rau qhov LED tawg-pov thawj teeb, ua degraded kev kawm.
Nyiaj hlau Disconnection:
Tus tseev tsim ntiaj teb nyiaj hlau sib txuas rau ib lub teeb LED yuav tawg, Ua rau tsis muaj hluav taws xob ntws thiab ua rau ib lub teeb tuag phenomenon. Qhov no kuj yuav muaj feem xyuam rau lwm LEDs’ lag luam, Tshwj xeeb tshaj yog vim LEDs ua hauj lwm ntawm cov voltages uas tsis muaj voltages (1.8V—2.2V liab, Daj, txiv kab ntxwv LEDs; 2.8—3.2V rau xiav, Ntsuab, LEDs) thiab feem ntau txuas nrog koob los yog parallel kom haum raws li kev ua hauj lwm sib txawv. Yog hais tias ib tug COJ hauv circuit Court muaj ib qhib thoob ntiaj teb sib txuas, Tag nrho koob yuav tsis teeb, ua qhov teeb meem loj tshaj lwm tus.
Leakage tam sim no:
Excessive leakage tam sim no yuav ua rau lub PN junction tsis tau, tiv thaiv kom tsis txhob muaj teeb los ntawm kev noj haus. Feem ntau, Qhov no tsis muaj feem xyuam rau lub lag luam ntawm lwm LEDs.
Txias muag ob leeg:
Tus mob khaub thuas muag ob leeg tshwm sim thaum lub LED bead, nti, tsis ruaj ntseg muag. Tshawb nrhiav qhov no, Tshav kub kub COJ ua rau 200-300°C siv ib lub teeb, Ces tshem cov tshav kub kub thiab txuas nrog ib lub roj teeb 3V khawm roj teeb rau lub LED hauv lub polarity polarity. Yog hais tias cov LED teeb tab sis dims li cov hlau lead txias cia, qhov no qhia tau hais tias tus mob khaub thuas muag. Cua kub tso cai rau cov hlau los nthuav thiab ua rau tus tseev tsim ntiaj teb muag taw tes, enabling tus COJ mus teeb. Raws li qhov txias txo thiab cov hlau sib cog lus, qhov zoo sib xws, thiab cov LED puv. Txoj kev no yog ib yam uas qhia siv kuj zoo nyob rau hauv kev qhia txias muag pob qij txha.
