Surface Μount Midziyo, Chiedza Yakatemerwa Dhiodhi
Iyo SMD LED idiki uye yakareruka chip inoremberedzwa muepoxy resin.
Izvi zvinopa kupenya kwakanyanyisa nepo ichichengetedza yakaderera simba rekushandisa kana ichienzaniswa neimwe mhando mabhuru (semuenzaniso. Incandescent).
Kazhinji voltage inoda paSMD LED iri approx 2 - 3.6V *, 0.02A-0.03A. Naizvozvo ine yakaderera kwazvo magetsi uye amperage zvinodiwa.
Inofananidzwa ne incandescent bulbs, simba rekushandisa riri pa 1 / 8th. Mumamiriro akakwana tarisiro yehupenyu inogona kusvika seanosvika zviuru zana hrs.
Akakurumbira eSMDs, ndeechigadzirwa n.s 3528 uye 5050.
SMD 3528 irimwenje mwenje inoburitsa package (chip), nepo SMD 5050 iri mukati me3 mwenje inoburitsa package.
Iyo 3528 inodaidzwa kuti irondedzere kukura kweiyo chip (35x28mm), nepo iko kushandiswa kuri kuita ingangoita 12V * 0.08W / chip.
Kupesana, SMD 5050 zviyero zviri 50x50mm, uye simba rayo rekushandisa iri 12V * 0.24W / chip.
Pfungwa 5050 SMD inopenya katatu kupfuura 3528.
* Cherekedza: apo isu tichiti 12V, zvakadaro isu takatsanangura pamusoro apa kuti ndeye 2-3,6V paSMD.
Saka mune SMD LED tepi isu hatigone kukwirisa-pasi pe3 SMDs (4x3smd = 12V)
Zvakanakira:
Direct simba kuchengetedza nekuda kwekushandisa kwakaderera.
Kunopisa kupisa emittion.
Hapana kudikanwa kwekuchengetedzwa nekuda kweiyo yakakura kwazvo tarisiro yehupenyu (saka yakaderera kumhanya mutengo).
Chiedza chena chinowedzera iwo chaiwo mavara ezvigadzirwa zvako zvinoratidzwa.
Iwo maSMD anoshandiswa neUNIKE anobva kumarudzi epasirose akakurumbira maLumileds, CREE, Osram ine yakagadzikana mhando, kuvimbika uye kuita Parizvino, Lumileds 2835SMD, 3030SMD uye 5050SMD dzinonyanya kushandiswa. Iyo tembiricha tembiricha ndeye 3000K / 4000K / 5000K / 5700K / 6500K inowanikwa, uye iyo CRI inosarudzika 70/80 / 90Ra. Kubwinya kunovhenekera kwerambi rese kwawana 170lm / Watt yakanyanya kubwinya kushanda. Hupenyu hwemwenje hunogona kunge hwakareba seanosvika maawa zviuru zana. UNIKE yakaziva zvakanyanya iyo yakasvibirira, yepamusoro-inoshanda, simba-kuponesa uye zvakatipoteredza zvine mwenje zvinangwa.
