Ba a yi la'akari da kewayon canjin fitilar fitilar LED VF ba, wanda ke haifar da ƙarancin ingancin fitilar, har ma da ƙimar farashin ƙirar tushen hasken LED a cikin madaidaicin tushen hasken LED. Gabaɗaya an haɗa shi da igiyoyin LED da yawa na LEDs. yawa. VF na LED yana canzawa tare da canjin zafin jiki. Gabaɗaya, a halin yanzu na yau da kullun, VF yana zama ƙasa a babban zafin jiki, kuma VF ya zama babba a ƙananan zafin jiki. Sabili da haka, ƙarfin aiki na nauyin fitilun LED a babban zafin jiki ya dace da VOL, kuma nauyin nauyin wutar lantarki na LED yana aiki a ƙananan zafin jiki ya dace da VOH. Lokacin zabar faifan LED, kewayon ƙarfin fitarwa na direba ya fi VOL VOH girma. Idan farashin tushen hasken LED zuwa babban ƙarfin fitarwa ya fi ƙasa da VOH, haƙurin fitilun a ƙananan zafin jiki bazai isa ainihin ikon ba. Idan faifan LED ɗin da aka zaɓa zuwa ƙananan ƙarfin lantarki ya fi VOL girma, ana iya yin tuƙi a babban zafin jiki a babban zafin jiki. Abin da ake fitarwa ya wuce iyakar aikin, aikin ba shi da kwanciyar hankali, fitilu za su yi haske, da dai sauransu. Amma m farashin da kuma yadda ya dace la'akari, ba za ka iya makance bi kewayon LED direban ta ultra-wide fitarwa ƙarfin lantarki kewayon: saboda direban ƙarfin lantarki ne kawai a cikin wani kewayon, da drive yadda ya dace shi ne mafi girma yadda ya dace. Bayan ƙetare kewayon, inganci da ƙarfin wutar lantarki (PF) za su lalace. A lokaci guda, ƙirar ƙirar ƙarfin lantarki na direba yana da faɗi da yawa, wanda zai haifar da ƙarin farashi kuma ba za a iya inganta ingantaccen aiki ba. Idan ba a yi la'akari da ma'aunin wutar lantarki da buƙatun ragewa ba, ikon ƙima na firikwensin LED yana nufin bayanan da aka auna ta yanayin da aka ƙididdigewa da ƙimar ƙarfin lantarki. Idan aka yi la'akari da cewa abokan ciniki daban-daban za su sami aikace-aikace daban-daban, yawancin masu samar da kebul na LED za su samar da madaidaicin raguwar wutar lantarki akan ƙayyadaddun samfuran nasu (nauyin na yau da kullun na VS na yanayi na yanayin zafi da kuma ɗaukar matakan rage ƙarfin shigarwar VS)). Layin ja yana nuna cewa lokacin da farashin tushen hasken LED ya kasance shigarwa 120VAC, raguwar rage wutar lantarki tare da yanayin zafi yana canzawa. Lokacin da yanayin zafi ya kasance ƙasa da 50 C, direba yana ba da damar cika nauyin 100. Lokacin da yanayin zafin jiki ya kai 70 C, direban zai iya rage nauyin kawai zuwa 60%. Lokacin da yanayin zafi ya canza tsakanin 50-70 C, nauyin tuƙi yana tare da zafin jiki tare da zafin jiki tare da haɓakar zafin jiki da raguwar layi. Layin shuɗi yana nuna cewa lokacin da direban LED ya shiga 230VAC ko 277VAC, nauyinsa yana da ƙarfin rage ƙarfin wuta tare da canje-canje a yanayin zafi. Tsarin shuɗi yana nufin cewa lokacin da direban LED ya kasance 55 C, ƙarfin rage ƙarfin fitarwa tare da canje-canje a cikin ƙarfin shigarwar yana canzawa. Lokacin da ƙarfin shigarwar ya kasance 140VAC, nauyin direba yana ba da damar 100 cikakkun kaya, kuma yayin da ƙarfin shigarwa ya ragu; idan ikon fitarwa ya kasance ba canzawa ba, shigar da halin yanzu zai tashi, yana haifar da karuwa a cikin asarar ƙarshen shigarwar, ingancin ya ragu, yanayin zafin na'urar zai tashi, kowane ma'aunin zafin jiki na iya yiwuwa. Ma'auni masu yawa na iya haifar da gazawar na'urori. Don haka, lokacin da ƙarfin shigarwar ya kasance ƙasa da 140VAC, ana buƙatar rage kayan fitarwa na direba tare da ƙarfin shigarwar da raguwar layin. Bayan fahimtar babban raguwa mai lankwasa da daidaitattun buƙatun, lokacin zabar farashin ƙirar tushen hasken LED, yakamata ku yi la'akari sosai kuma zaɓi bisa ga ainihin yanayin yanayin muhalli da yanayin yanayin shigar da wutar lantarki, kuma ku bar daidai don barin raguwar raguwar rage yawan raguwa.
