Miyezo yopangira nyali za LED zowunikira msewu

Mosiyana ndi magetsi a m'misewu wamba,Ma LED road lighting lightersGwiritsani ntchito magetsi a DC otsika mphamvu. Ubwino wapaderawu umapereka mphamvu zambiri, chitetezo, kusunga mphamvu, kusamala chilengedwe, kukhala ndi moyo wautali, nthawi yogwira ntchito mwachangu, komanso mtundu wowoneka bwino, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pamsewu.

Kapangidwe ka nyali ya LED yowunikira msewu kamakhala ndi zofunikira izi:

Mbali yofunika kwambiri ya kuwala kwa LED ndi kutulutsa kwake kuwala kolunjika. Ma LED amphamvu nthawi zambiri amakhala ndi zowunikira, ndipo kugwira ntchito bwino kwa zowunikira izi kumakhala kwakukulu kuposa kwa chowunikira cha nyali. Kuphatikiza apo, kuyesa kogwira ntchito bwino kwa kuwala kwa LED kumaphatikizapo kugwira ntchito bwino kwa chowunikira chake. Zowunikira za LED pamsewu ziyenera kukulitsa kutulutsa kwawo kuwala kolunjika, kuonetsetsa kuti LED iliyonse mu chowunikiracho ikutsogolera kuwala mwachindunji kudera lililonse la msewu wowunikira. Chowunikira cha chowunikiracho chimapereka kugawa kowonjezera kwa kuwala kuti chikwaniritse kugawa bwino kwa kuwala konse. Mwanjira ina, kuti magetsi amsewu akwaniritsedi zofunikira pakuwunikira ndi kufanana kwa miyezo ya CJJ45-2006, CIE31, ndi CIE115, ayenera kukhala ndi njira yogawa kuwala ya magawo atatu. Ma LED okhala ndi zowunikira ndi ma angles opangidwa bwino a beam amapereka kugawa bwino kwambiri kwa kuwala koyambirira. Mkati mwa chowunikira, kukonza malo okwerera ndi kulunjika kwa kuwala kwa LED iliyonse kutengera kutalika kwa chowunikiracho ndi m'lifupi mwa msewu kumalola kugawa bwino kwa kuwala kwachiwiri. Chowunikira cha mtundu uwu wa nyali chimagwira ntchito ngati chida chowonjezera chogawa kuwala kwachitatu, kuonetsetsa kuti kuwalako kukuwoneka kofanana pamsewu.

Mu kapangidwe ka magetsi a mumsewu, kapangidwe koyambira ka LED iliyonse yotulutsa mpweya kakhoza kukhazikitsidwa, ndipo LED iliyonse imalumikizidwa ku cholumikizira pogwiritsa ntchito cholumikizira cha mpira. Cholumikizira chikagwiritsidwa ntchito kutalika kosiyanasiyana ndi m'lifupi mwake, cholumikizira cha mpira chingasinthidwe kuti chikwaniritse njira yomwe mukufuna ya LED iliyonse.

Dongosolo lamagetsi la ma LED road lighting luminaires limasiyananso ndi la magwero achikhalidwe a magetsi. Ma LED amafuna dalaivala wapadera wamagetsi okhazikika, zomwe ndizofunikira kuti ntchito iyende bwino. Mayankho osavuta amagetsi osinthira nthawi zambiri amawononga zigawo za LED. Kuonetsetsa kuti ma LED omangidwa bwino ndi otetezeka ndi njira yofunika kwambiri yowunikira ma LED road lighting luminaires. Ma circuit a ma LED driver amafuna mphamvu yokhazikika. Chifukwa mphamvu yamagetsi yolumikizira ma LED imasiyana pang'ono panthawi yogwira ntchito, kusunga mphamvu yamagetsi yokhazikika ya LED drive kumatsimikizira mphamvu yokhazikika yotulutsa.

Kuti dera la dalaivala la LED liwonetse mawonekedwe a mphamvu yokhazikika, mphamvu yake yamkati yotulutsa, yomwe imawonedwa kuchokera kumapeto kwa mphamvu ya dalaivala, iyenera kukhala yokwera. Pakugwira ntchito, mphamvu yamagetsi imadutsanso kudzera mu mphamvu yamkati yotulutsa iyi. Ngati dera la dalaivala lili ndi step-down, rectifier-filtered, kenako DC constant current source circuit, kapena magetsi osinthira omwe amagwiritsidwa ntchito ndi resistor circuit, mphamvu yogwira ntchito yayikulu idzagwiritsidwa ntchito. Chifukwa chake, ngakhale mitundu iwiriyi ya ma driver circuit ikukwaniritsa zofunikira pa mphamvu yokhazikika yotulutsa, mphamvu yawo siyingakhale yokwera. Yankho lolondola la kapangidwe ndikugwiritsa ntchito dera losinthasintha lamagetsi logwira ntchito kapena mphamvu yamagetsi yapamwamba yoyendetsera LED. Njira ziwirizi zitha kuwonetsetsa kuti dera la dalaivala limasunga mawonekedwe abwino a mphamvu yokhazikika pomwe likusungabe mphamvu yosinthika kwambiri.

Kuyambira pa kafukufuku ndi chitukuko mpaka kutumizidwa kwa zinthu zomalizidwa,Ma nyali a LED a TIANXIANGkuonetsetsa kuti kuwala kukugwira ntchito bwino, kuunikira, kufanana, komanso chitetezo pa unyolo wonse, mogwirizana bwino ndi zosowa za kuunikira m'malo osiyanasiyana monga misewu ya m'matauni, misewu ya anthu ammudzi, ndi malo osungiramo mafakitale, kupereka chithandizo chodalirika cha chitetezo paulendo wausiku komanso kuunikira zachilengedwe.
