Njira Khumi Zodzitetezera pa Ma LED Street LightsLED Street Lights

Njira Khumi Zodzitetezera Kuwala Kwamsewu wa LED-Kuwala kwa Misewu ya LED Kuchuluka kwa ntchito kwa nyali za mseu za LED m'madera amasiku ano zakhala zikuthandiza kwambiri pakupita patsogolo kwaumisiri wounikira, makamaka mbali ziwiri za kupulumutsa mphamvu ndi kutsika kwa mpweya wa nyali za mumsewu wa LED zathandiza kwambiri anthu. Tiyeni tikambirane ndondomeko ya ntchito tsiku ndi tsiku. Zinthu 10 zomwe magetsi a mumsewu a LED ayenera kusamala. 1. Magetsi a magetsi a mumsewu wa LED ayenera kukhala nthawi zonse Zowunikira za nyali za mumsewu wa LED zimatsimikizira kuti zimakhudzidwa ndi chilengedwe. Mwachitsanzo, pamene kutentha kumasintha, mphamvu ya LED idzawonjezeka; Kuonjezera apo, magetsi a LED adzawonjezeka ndi kuwonjezeka kwa magetsi. Ngati ntchito yanthawi yayitali ipitilira pakali pano, ifupikitsa kwambiri moyo wautumiki wa mikanda ya nyali ya LED.

LED nthawi zonse ndikuwonetsetsa kuti mtengo wapano wa ntchito yake umakhalabe wosasinthika pamene zinthu zachilengedwe monga kutentha ndi kusintha kwa magetsi. 2. Kulondola kwanthawi zonse kwa magetsi a magetsi a mumsewu wa LED Kulondola kwanthawi zonse kwamagetsi ena pamsika ndi koyipa, cholakwikacho chimatha kufikira ± 8%, ndipo cholakwika chanthawi zonse chimakhala chachikulu kwambiri. Zofunikira zonse zili mkati mwa ± 3%.

Malinga ndi kapangidwe ka 3%. Mphamvu yopangira magetsi iyenera kukonzedwa bwino kuti ikwaniritse cholakwika ± 3%. 3. Mphamvu yogwiritsira ntchito magetsi a magetsi a LED mumsewu Nthawi zambiri, mphamvu yogwiritsira ntchito ma LED ndi 3.0-3.5V. Pambuyo poyesedwa, ambiri a iwo amagwira ntchito pa 3.2V, kotero kuti chiwerengero chowerengera chochokera ku 3.2V ndichomveka.

Magetsi onse a mikanda ya nyali ya N mu mndandanda = 3.2 * N 4. Kodi ndi nthawi iti yoyenera yogwiritsira ntchito magetsi a magetsi a mumsewu wa LED? Mwachitsanzo, oveteredwa ntchito panopa wa LED ndi 350mA, mafakitale ena ntchito pa chiyambi, ndi kupanga 350mA, Ndipotu, kutentha ntchito kwambiri pansi pano, pambuyo mayesero ambiri kufananitsa, ndi bwino kupanga izo monga 320mA . Chepetsani kutulutsa kutentha, kuti mphamvu zambiri zamagetsi zitha kusinthidwa kukhala mphamvu yowunikira yowoneka. 5. Kodi kugwirizana kwa mndandanda-kufanana ndi kufalikira kwa magetsi a magetsi a magetsi a LED mumsewu? Pofuna kuti magetsi a magetsi a mumsewu wa LED azigwira ntchito mumtundu wambiri wamagetsi a AC85-265V, kugwirizanitsa kwa LED kofanana ndi gulu lowala ndikofunikira kwambiri.

Yesetsani kuti musagwiritse ntchito magetsi ambiri, akhoza kugawidwa mu AC220V, AC110V momwe mungathere, kuti mutsimikizire kudalirika kwa magetsi. Popeza mphamvu panopa zambiri si akutali sitepe-pansi zonse panopa mphamvu, pamene chofunika voteji ndi 110V, linanena bungwe voteji sayenera upambana 70V, ndipo chiwerengero cha kugwirizana mndandanda sayenera upambana 23. Pamene athandizira voteji ndi 220V, voteji linanena bungwe akhoza kufika 156V.

Ndiko kunena kuti, chiwerengero cha kugwirizana kwa mndandanda sichidutsa zingwe 45. Chiwerengero cha maulumikizidwe ofananira sichiyenera kukhala chokulirapo, apo ayi ntchito yamakono idzakhala yayikulu kwambiri ndipo magetsi adzatentha kwambiri. Palinso njira yolumikizira magetsi ambiri, APFC yolipirira mphamvu yogwira ntchito ndikuyamba kugwiritsa ntchito L6561/7527 kukweza voteji mpaka 400V, kenako ndikutsika, zomwe ndizofanana ndi magetsi osinthira awiri.

Pulogalamuyi imagwiritsidwa ntchito pokhapokha pazifukwa zina. 6. Kudzipatula / kusadzipatula Kawirikawiri, ngati mphamvu yodzipatula imapangidwira 15W ndikuyikidwa mu chubu chamagetsi cha nyali ya LED ya mumsewu, transformer ndi yochuluka kwambiri ndipo imakhala yovuta kuiyika. Imatengera makamaka mawonekedwe a danga ndipo zimadalira momwe zinthu zilili. Nthawi zambiri, kudzipatula kumangofikira 15W, ndipo zomwe zimapitilira 15W ndizosowa, ndipo mtengo wake ndi wokwera mtengo kwambiri.

Choncho, chiŵerengero cha mtengo-ntchito ya kudzipatula sipamwamba. Nthawi zambiri, kusadzipatula ndikofala, ndipo voliyumu imatha kukhala yaying'ono, ndipo kutalika kwake kumatha kukhala 8mm. Ndipotu, palibe vuto ngati njira zodzitetezera zosadzipatula zimatengedwa bwino. Ngati danga likuloleza, litha kugwiritsidwanso ntchito ngati magetsi akutali. 7. Kodi magetsi a magetsi a mumsewu wa LED angafanane bwanji ndi bolodi la mikanda? M'malo mwake, ngati musankha kulumikizana kofananirako kofananira, voteji ndi zomwe zimagwiritsidwa ntchito pa LED iliyonse zidzakhala zofanana, koma magetsi adzakhala ndi ntchito yabwino kwambiri.

Njira yabwino ndikuyankhulirana ndi wopanga magetsi poyamba ndikupanga zopangira. Kapena pangani magetsi anuanu. 8. Kuwala kwa magetsi mumsewu wa LED Mphamvu yolowetsayo imachotsa mphamvu yotulutsa mphamvu, chizindikiro ichi ndi chofunikira kwambiri, mtengo wake ndi wotsika kwambiri, umakhala wotsika kwambiri, zomwe zikutanthauza kuti gawo lalikulu la mphamvu zolowera limasandulika kutentha ndi kutulutsa; ngati itayikidwa mu nyaliyo, imatulutsa kutentha kwambiri, kuphatikiza kutentha komwe kumapangidwa ndi chiŵerengero chowala bwino cha LED yathu, kumapangitsa kutentha kwambiri. Ndipo moyo wa ziwalo zonse zamagetsi mkati mwa magetsi athu udzafupikitsidwa pamene kutentha kumakwera. Choncho mphamvu ndiye chinthu chofunika kwambiri chomwe chimatsimikizira moyo wa magetsi. Chofunikira ndichakuti magwiridwe antchito sangakhale otsika kwambiri, apo ayi kutentha komwe kumagwiritsidwa ntchito pamagetsi kumakhala kwakukulu.

Kuchita bwino kwa mtundu wosakhala wodzipatula ndikokwera kwambiri kuposa mtundu wakutali, nthawi zambiri kuposa 80%. Komabe, kuchita bwino kumakhudzana ndi njira yolumikizirana yolumikizana ndi bolodi lowala. 9. Kutentha kwa kutentha kwa gwero la kuwala kwa msewu wa LED Chinthu chachikulu cha njira yothetsera kutentha ndikuti nthawi ya moyo wa mikanda ya nyali ya LED ikhoza kukulitsidwa kwambiri ikagwiritsidwa ntchito pansi pa chikhalidwe chosawotcha. Nthawi zambiri, aluminiyamu alloy amagwiritsidwa ntchito, zomwe zimakhala zosavuta kutaya kutentha. Izi zikutanthauza kuti, mikanda yamagetsi yamagetsi ya LED imayikidwa pagawo la aluminiyamu, ndipo malo opangira kutentha kwakunja amakulitsidwa momwe angathere. 10. Kuziziritsa magetsi kwa nyali ya msewu wa LED Chinthu chachikulu cha kutentha kwa kutentha ndi chakuti mikanda yamagetsi yamagetsi ya LED imatha kutalikitsa moyo wawo ngati ikugwiritsidwa ntchito mopanda kutentha. Kawirikawiri, ma radiator a aluminiyamu amagwiritsidwa ntchito, omwe ndi osavuta kutaya kutentha.

Izi zikutanthauza kuti, mikanda yamagetsi yamagetsi ya LED imayikidwa pagawo la aluminiyamu, ndipo malo opangira kutentha kwakunja amakulitsidwa momwe angathere. Zinthu khumi zomwe zili pamwambazi zasanthula mfundo zazikuluzikulu za nyali zamsewu za LED mwatsatanetsatane kwa ife. Kugwiritsa ntchito moyenera kudzapititsa patsogolo moyo wautumiki wa nyali zamsewu za LED ndikuchepetsa ndalama zopangira. Ndikukhulupirira kuti aliyense adzakhala ndi chidwi kwambiri.
