Game da LED direban

Gabatarwa ga direban LED

LEDs sune na'urorin semiconductor masu ƙima tare da halayen zafin jiki mara kyau.Sabili da haka, yana buƙatar daidaitawa da kariya yayin aiwatar da aikace-aikacen, wanda ke haifar da manufar direba.Na'urorin LED suna da kusan matsananciyar buƙatu don ikon tuƙi.Ba kamar kwararan fitila na yau da kullun ba, ana iya haɗa LEDs kai tsaye zuwa wutar lantarki mai karfin 220V AC.

Aiki na LED direban

Dangane da ka'idodin wutar lantarki na grid ɗin wutar lantarki da halayen halayen wutar lantarki na direban LED, yakamata a yi la'akari da waɗannan abubuwan yayin zaɓar da zayyana wadatar wutar lantarki ta LED:

Babban dogaro: musamman kamar direban fitilun titin LED.Kulawa yana da wahala kuma yana da tsada a wurare masu tsayi.

Babban inganci: Hasken haske na LEDs yana raguwa tare da ƙara yawan zafin jiki, don haka zubar da zafi yana da mahimmanci, musamman lokacin da aka shigar da wutar lantarki a cikin kwan fitila.LED shine samfurin ceton makamashi tare da ingantaccen ƙarfin tuki, ƙarancin wutar lantarki da ƙarancin zafi a cikin fitilun, wanda ke taimakawa wajen rage yawan zafin fitilun da jinkirta jinkirin hasken LED.

Babban ƙarfin wutar lantarki: Ƙarfin wutar lantarki shine buƙatun grid na wutar lantarki akan kaya.Gabaɗaya, babu alamun tilas na kayan lantarki da ke ƙasa da watts 70.Ko da yake ma'aunin wutar lantarki guda ɗaya mai ƙarancin wutar lantarki yana da ƙasa sosai, yana da ɗan tasiri akan grid ɗin wutar lantarki.Duk da haka, idan an kunna fitilu da dare, nau'ikan nau'ikan za su kasance da yawa sosai, wanda zai haifar da nauyi mai tsanani akan grid.An ce don direban LED na 30 zuwa 40 watts, za a iya samun wasu buƙatun ƙididdiga don ƙarfin wutar lantarki a nan gaba.

LED direban manufa

Matsakaicin dangantaka tsakanin jujjuyar wutar lantarki ta gaba (VF) da na yanzu (IF).Ana iya gani daga lanƙwan cewa lokacin da ƙarfin wutar lantarki na gaba ya wuce ƙayyadaddun ƙira (kimanin 2V) (yawanci ana kiransa on-voltage), ana iya la'akari da cewa IF da VF sun daidaita.Dubi teburin da ke ƙasa don halayen lantarki na manyan manyan LED masu haske na yanzu.Ana iya gani daga tebur cewa mafi girman IF na yanzu super haske LEDs iya isa 1A, yayin da VF yawanci 2 zuwa 4V.

Tun da yawancin halayen haske na LED ana kwatanta su azaman aikin halin yanzu maimakon aikin ƙarfin lantarki, wato, lanƙwan dangantaka tsakanin hasken haske (φV) da IF, yin amfani da direba mai mahimmanci na yanzu zai iya sarrafa haske. .Bugu da kari, digon wutar lantarki na gaba na LED yana da ingantacciyar kewayo (har zuwa 1V ko sama).Kamar yadda ake iya gani daga madaidaicin VF-IF a cikin adadi na sama, ƙaramin canji a cikin VF zai haifar da babban canji a cikin IF, yana haifar da haske mai girma da manyan canje-canje.

Matsakaicin alaƙa tsakanin zafin LED da kwararar haske (φV).Hoton da ke ƙasa yana nuna cewa hasken wuta ya yi daidai da yanayin zafi.Hasken haske a 85°C shine rabin hasken haske a 25°C, kuma fitowar haske a 40°C shine sau 1.8 na hasken haske a 25°C.Canje-canjen yanayin zafi kuma suna da takamaiman tasiri akan tsayin igiyoyin LED.Sabili da haka, zubar da zafi mai kyau shine garanti don tabbatar da cewa LED yana kula da haske akai-akai.

Sabili da haka, ta amfani da tushen wutar lantarki akai-akai don tuƙi ba zai iya tabbatar da daidaiton hasken LED ba, kuma yana shafar amincin, rayuwa da ƙarancin haske na LED.Sabili da haka, manyan LED masu haske galibi ana sarrafa su ta hanyar tushen yau da kullun.
