Nyali za LED zokhala ndi mitengo yosiyana ndizosiyana kwambiri.
Kumanga kwa nyali za LED kumawoneka kosavuta, koma pali zambiri zomwe ziri ndendende magwero a kusiyana. Chifukwa cha nkhondo yamtengo wapatali yomwe ikuchulukirachulukira, zinthu zomwe zimakhala ndi mawonekedwe ofanana, mawonekedwe ndi magwiridwe antchito zimakhala ndi kusiyana kwamitengo nthawi 2-3. Zifukwa zazikulu za kusiyana kwamitengo ndi izi:
1.Kuwala
Kuwala kwa ma LED ndi kosiyana ndipo mtengo wake ndi wosiyana. Mofanana ndi nyali zachikhalidwe za incandescent, mtengo wa nyali zotentha kwambiri ndizokwera kwambiri. Kuwala kwa mababu a LED kumawonetsedwa mu lumens. Kukwera kwa lumens, nyali zowala komanso zodula kwambiri.
2. Antistatic luso
Ma LED okhala ndi antistatic katundu wamphamvu amakhala ndi moyo wautali motero ndi okwera mtengo. Ma LED okhala ndi antistatic pa 700V nthawi zambiri amagwiritsidwa ntchito pakuwunikira kwa LED.
3. Wavelength
Ma LED okhala ndi kutalika komweko amakhala ndi mtundu womwewo. Ngati mtundu uli wofanana, mtengo wake ndi wapamwamba. Ndizovuta kwa opanga opanda ma spectrophotometers a LED kuti apange zinthu zamtundu woyera.
4. Kutayikira panopa
Nyali ya LED ndi chounikira chopanda unidirectionally conductive, ndipo ngati pali chosinthira, chimatchedwa kutayikira. Ma LED okhala ndi kutayikira kwakukulu pakali pano amakhala ndi moyo waufupi komanso mtengo wotsika, ndipo mtengo wake ndi wapamwamba.
5. Beam angle
Ma LED okhala ndi ntchito zosiyanasiyana amakhala ndi ngodya zowunikira zosiyanasiyana. Ngongole yapadera yowunikira, mtengo wake ndi wapamwamba. Monga mbali zonse diffusing, kugawa zonse kuwala, 360 ° kuyatsa, etc., mtengo ndi apamwamba.
6. Utali wa moyo
Chinsinsi cha makhalidwe osiyanasiyana ndi moyo wautali, ndipo moyo umatsimikiziridwa ndi kuwonongeka kwa kuwala. Kuwola kochepa, moyo wautali, ndi moyo wautali umabwera ndi mtengo wapamwamba. Moyo wapakati wa nyali za LED ndi wapamwamba kuposa wa nyali zachikhalidwe.
7. Chip cha LED
Chowunikira cha LED ndi chip, ndipo mtengo wa chip umasiyana kwambiri. Ma chips ku Japan ndi United States ndi okwera mtengo, ndipo mtengo wa tchipisi ta LED kuchokera kwa opanga aku Taiwanese ndi China ndi wotsika kuposa waku Japan ndi United States. Zambiri zamtengo wa nyali za LED zimakhazikika pa chip, ndipo chip ndi chofanana ndi mtima wa nyali za LED.
Nyali za LED zokhala ndi mitengo yotsika kwambiri zimatha kupangidwa ndi zinthu zotsika komanso zovuta. Sikuti amangotsimikiziridwa kuti ali ndi chitetezo, komanso amakayikira ponena za khalidwe la mankhwala. Chifukwa chake, ogula akasankha nyali za LED, ayenera kuwona magawo azogulitsa ndi mtundu wazinthu.
