Yesani kuwala kwa msewu wa LED

Kuwala kwa msewu wa LED nthawi zambiri kumakhala kutali ndi ife, ngati kulephera kwa kuwala, tiyenera kunyamula zida zonse zofunika ndi zida, ndipo zimafunikira luso kuti zikonze. Zimatenga nthawi ndipo mtengo wokonza ndi wolemetsa. Choncho kuyesa ndi mbali yofunika kwambiri. Kuyesa kwa kuwala kwa msewu wa LED kuphatikiza kuyesa kwamadzi kapena chitetezo cha ingress (IP), kuyesa kwa kutentha, kuyesa kwachitetezo (IK), kuyesa kukalamba, ndi zina zotero.

Kuyesa kwa Ingress Protection (IP).

Kumatsimikizira ngati kuwala kudzateteza mbali zogwirira ntchito ku madzi, fumbi, kapena kulowetsedwa kwa chinthu cholimba, kusunga mankhwala otetezedwa ndi magetsi komanso okhalitsa. Kuyesa kwa IP kumapereka muyeso wobwerezabwereza kuti mufananize chitetezo champanda. Kodi ma IP amawoneka bwanji? Nambala yoyamba pamlingo wa IP imayimira kuchuluka kwa chitetezo ku chinthu cholimba kuchokera ku dzanja kupita ku fumbi, ndipo yachiwiri pamlingo wa IP imayimira kuchuluka kwa chitetezo kumadzi oyera kuchokera ku mvula 1mm mpaka kumizidwa kwakanthawi mpaka 1m. .

Tengani IP65 mwachitsanzo, "6" amatanthauza kusalowa fumbi, "5" amatanthauza kutetezedwa ku jeti lamadzi kuchokera kumbali iliyonse. IP65 mayeso amafuna kuthamanga 30kPa pa mtunda wa 3m, ndi madzi voliyumu 12.5 malita pa mphindi, mayeso nthawi 1 miniti pa lalikulu mita kwa mphindi zosachepera 3. Nthawi zambiri kuyatsa kwakunja IP65 kuli bwino.

Madera ena amvula amafuna IP66, "6" amatanthauza kutetezedwa ku majeti amphamvu amadzi ndi nyanja zolemera. Kuyesa kwa IP66 kumafuna kuthamanga kwa 100kPa pamtunda wa 3m, ndi madzi voliyumu 100 malita pa mphindi, nthawi yoyeserera mphindi imodzi pa mita imodzi kwa mphindi zosachepera 3.

Kuyesedwa kwa Impact Protection (IK).

Miyezo ya muyeso wa IK: IEC 62262 imatchula momwe malo otsekera amayenera kuyesedwa kuti ayesedwe ndi ma IK omwe amatanthauzidwa ngati mulingo wachitetezo omwe amaperekedwa motsutsana ndi zovuta zamakina akunja.

IEC 60598-1 (IEC 60529) imatchula njira yoyesera yomwe imagwiritsidwa ntchito kuyika ndikuyesa kuchuluka kwa chitetezo chomwe mpanda umapereka pakulowerera kwa zinthu zolimba zosiyanasiyana kuyambira zala ndi manja kupita ku fumbi labwino komanso chitetezo ku kulowetsedwa kwamadzi kuchokera ku madontho akugwa mpaka kugwa. jeti yamadzi yothamanga kwambiri.

IEC 60598-2-3 ndi International Standard for Luminaires for Road and Street Lighting.

Miyezo ya IK imatanthauzidwa ngati IKXX, pomwe "XX" ndi nambala yochokera ku 00 mpaka 10 yosonyeza madigiri a chitetezo choperekedwa ndi zotchinga zamagetsi (kuphatikizapo zowunikira) motsutsana ndi zovuta zamakina akunja. Sikelo yoyezera ya IK imazindikiritsa kuthekera kwa malo otsekeredwa kukana mphamvu zomwe zimayesedwa mu ma joules (J). IEC 62262 imafotokoza momwe mpanda uyenera kuyikidwa kuti uyesedwe, momwe mumlengalenga umafunikira, kuchuluka ndi kugawa kwazomwe zimayesedwa, ndi nyundo yamphamvu yomwe iyenera kugwiritsidwa ntchito pamlingo uliwonse wa mlingo wa IK.

Kupanga koyenerera kumakhala ndi zida zonse zoyesera. Ngati mungasankhe kuwala kwa msewu wa LED pulojekiti yanu, ndikwabwino kufunsa wogulitsa wanu kuti akupatseni malipoti onse oyeserera.
