Zinsinsi Zing'ono khumi za LED Street Lamp Technology

Ntchito yowunikira yamakampani owunikira a LED sikuti imangokhudzidwa ndi chilengedwe chapadziko lonse lapansi, komanso mawonekedwe ake apadera amakampaniwo. Magetsi a magetsi a mumsewu wa LED ndiye chinthu chofunikira kwambiri pakukula kwamakono kwa LED. Kwa mapangidwe okhudzana ndiukadaulo wa LED, pali pano mayankho ambiri komanso njira zapadera zopangira. Tiyeni tiyang'ane pa iwo mmodzimmodzi. N'chifukwa chiyani magetsi a magetsi a mumsewu wa LED amakhala osasinthasintha? Makhalidwe a zida zowunikira za LED zimatsimikizira kuti zimakhudza kwambiri chilengedwe. Mwachitsanzo, kutentha kumawonjezeka, magetsi a LED awonjezeka, magetsi amawonjezeka, ndipo magetsi a LED awonjezeka. Kupitilira kwa nthawi yayitali kuposa ntchito yomwe idavoteledwa posachedwa kudzafupikitsa mikanda ya nyali ya LED. Kuwongolera kwanthawi zonse kwa LED ndikuwonetsetsa kuti mtengo wake womwe ukugwira ntchito sukusintha pamene zinthu zachilengedwe monga kutentha ndi magetsi zikusintha. 2. Kuwongolera kwamagetsi kwa LED mumsewu wa Hengli Kulondola kwanthawi zonse pamsika ndikosauka, monga chiwembu chotchuka pamsika, monga dongosolo lodziwika bwino la mtsinje, cholakwika chimafika. ±8%, cholakwika chanthawi zonse chimakhala chachikulu kwambiri. Kaŵirikafunika ±3%. Malinga ndi 3% kapangidwe kake. Mphamvu yopangira magetsi iyenera kukonzedwa bwino isanakwaniritsidwe ±3%. 3. Mphamvu yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi ya LED nthawi zambiri imakhala 3.0-3.5V. Pambuyo poyesedwa, ambiri a iwo amagwira ntchito mu 3.2V, kotero kuwerengera kwa 3.2V ndikomveka. Magetsi okwana a n mikanda ya nyali mu mndandanda = 3.2 * N4, magetsi opangira magetsi pamsewu wa LED ndi oyenera kwambiri, monga magetsi ogwiritsira ntchito a LED 350 mAh, mafakitale ena amagwiritsidwa ntchito pachiyambi, ndi mapangidwe ake. 350mAh. Ndipotu, ntchito pansi pa panopa ndi yotentha kwambiri. Pambuyo poyeserera kangapo, ndiyenera kupangidwa ngati 320 mAh. Yesetsani kuchepetsa kutentha kwa tsitsi, kuti magetsi ochulukirapo akhale mphamvu yowoneka bwino. 5. Kodi voteji yamagetsi yamagetsi ya LED Street ndi yayikulu bwanji? Kuti magetsi a LED azitha kugwira ntchito mumitundu yosiyanasiyana yamagetsi, AC85-265V, mndandanda wa LED ndi njira yolumikizira bolodi lowala ndizofunikira kwambiri. Yesetsani kuti musagwiritse ntchito magetsi ambiri momwe mungathere, akhoza kugawidwa mu AC220V, ndipo AC110V imasanjidwa momwe mungathere, kuti mutsimikizire kudalirika kwa magetsi. Popeza magetsi panopa nthawi zambiri sanali kudzipatula -voltage zonse panopa mphamvu, pamene voteji ndi 110V, linanena bungwe voteji si upambana 70V, ndipo chiwerengero cha mndandanda si upambana 23 chingwe. Pamene athandizira voteji 220V, linanena bungwe voteji akhoza kufika 156V. Mwanjira ina, kuchuluka kwa mndandanda sikudutsa zingwe 45. Musakhale ndi nambala yofananira kwambiri, apo ayi ntchitoyo ndi yayikulu kwambiri, ndipo magetsi amatenthedwa kwambiri. Palinso yotakata -magetsi njira. APFC gwero mphamvu chipukuta misozi ndi ntchito L6561/7527 kukweza voteji kuti 400V, ndiyeno kuchepetsa voteji. Njira yothetsera vutoli imagwiritsidwa ntchito pokhapokha pazikhalidwe zinazake. 6, kudzipatula / osadzilekanitsa ambiri kudzipatula magetsi, ngati apangidwa 15W, anaika mu LED msewu kuwala chitoliro mphamvu, thiransifoma ake ndi lalikulu kwambiri, n'kovuta kuikamo. Izo makamaka zimadalira dongosolo danga zimadalira zinthu zenizeni. Nthawi zambiri, kudzipatula kumatha kukwaniritsa 15W, kuchepera 15W, ndipo mtengo wake ndi wokwera mtengo kwambiri. Choncho, mtengo - ogwira ntchito kudzipatula si mkulu. Nthawi zambiri, kusadzipatula kumakhala kofala kwambiri, voliyumu imatha kukhala yaying'ono, ndipo yocheperako imatha kukhala 8 mm kutalika. M'malo mwake, njira zodzitetezera zosadzipatula zimachitika. Malo amalola angagwiritsidwenso ntchito ngati kudzipatula magetsi. 7. Kodi magetsi a mumsewu wa LED angagwirizane bwanji ndi bolodi la mikanda? Makasitomala ena amayamba kupanga bolodi la nyali, kenako amapeza magetsi. Ndizovuta kupeza magetsi oyenera, kaya panopa ndi yaikulu kwambiri, ndipo magetsi ndi ochepa kwambiri (monga 7x1wi). > 350mA, kapena V25V), zotsatira zake ndi kutentha kwambiri, kutsika kwachangu, kapena kusakwanira kwamagetsi amagetsi. Ndipotu, kusankha njira yabwino yolumikizira ndi LED iliyonse ndi yofanana, koma zotsatira za magetsi zimatha kuchita bwino kwambiri. Njira yabwino ndikuyankhulirana ndi opanga magetsi poyamba ndi kupanga telala. Kapena kupanga magetsi. 8. LED's skewers ndi PFC power factor areolation input AC220V high -voltage end electrolytic capacitance mphamvu nthawi zambiri imalowetsa mphamvu 1W = 1UF, AC110V1W = 2UF pakadali pano ili ndi milandu itatu yamagetsi a PFC: imodzi ilibe PFC yopanda chipukuta misozi yamagetsi Kwa mabwalo odzipereka, Mtengo wa PF nthawi zambiri umakhala pafupifupi 0.65; chachiwiri ndi passive power factor compensation PFC circuit, ndiko kuti, kuwala kwa chipukuta misozi yamagetsi osasunthika, ndipo gulu loyendetsa dera loyenda ndilodalirika kwambiri, PF PF, PF Mtengo nthawi zambiri umakhala pafupi ndi 0.92; mitundu itatu ya yogwira yogwira 7527/6561 dera amagwiritsidwanso ntchito, ndiko kuti, malipiro gwero mphamvu chinthu, wotchedwa AC220V mu dera APFC, AC110V angagwiritse ntchito capacitors electrolytic wa mphamvu yomweyo, kusankha 1W = 1W = 1.5uf. Mtengo wa PF ukhoza kufika pa 0.99, koma mtengo wa yankho ili ndi woipa pang'ono kuposa yankho lachiwiri. Choncho njira yachiwiri imagwiritsidwa ntchito kwambiri. Kwa dera losagwira ntchito la PFC: lomwe limadziwikanso kuti Chan -type PFC dera, mawonekedwe ake amagetsi a DC ndi theka la nsonga yamagetsi a AC. Ngati zolowetsazo ndi 220V, nsonga yake ndi 220 * 1.414 = 312V, ndipo theka la nsonga yamagetsi ndi 156V. Chifukwa chake, kuchuluka kwa mikanda yamagetsi yamagetsi ya LED kumafikira zingwe 45 pansipa. Choncho, ngati mukufuna kupeza ndi lalikulu mphamvu zinthu, chiwerengero cha nyali sayenera kukhala yaing'ono, apo ayi bwino ntchito boma sichidzatheka. Mphamvu yamagetsi iyenera kukwaniritsa mphamvu zotulutsa. Zing'onozing'ono zomwe zikugwira ntchito panopa pazigawo zamagetsi mumagulu ogwiritsira ntchito magetsi, moyo wautali utalikirapo, moyo umakhala wamfupi. Mikanda yamagetsi yamagetsi ya LED imakhudzidwa kwambiri ndi kuchuluka kwa kulumikizana. Kuchuluka kwa kulankhulana, kumapangitsanso kutonthoza kwa kuwala. Nthawi zambiri, ma capacitor a electrolytic amayenera kugwiritsidwa ntchito kusunga voteji, ndipo voteji yamagetsi otulutsa kumapeto amagwiritsidwa ntchito momwe angathere. Mphamvu ya electrolytic capacitance kumapeto kwa voteji pansi sayenera kukhala yaying'ono kwambiri. Non -isolation input end high -voltage electrolytic capacitance kusankha ndikofanana ndi kudzipatula, ndipo zotuluka - end capacitor kusankha 1UF
