Fashewar Shenhai-Hujja
Kasuwar ta cika da nau'ikan fitilu masu hana fashewar LED, kowane da daban-daban bayani dalla-dalla daga daban-daban masana'antun. Don haka, yadda za a zabi daga wannan fadi da kewayon kayayyakin? Kamar yadda akwai wasu ma'auni don kimanta aikin na'urorin hasken wuta na LED, Anan akwai jagora na musamman don taimakawa cikin tsarin siye da kuma taimakawa guje wa asarar ayyukan hasken wuta saboda rashin dacewa..
1. Index na nuna launi (CRI):
Kafin siye, yana da mahimmanci don bincika ƙayyadaddun samfur ko tambayi wakilin tallace-tallace game da CRI. Gabaɗaya, Fitilar LED tare da CRI tsakanin RA80 da 100 nuna kyakkyawan aikin launi; wadanda ke tsakanin RA50 da 79 suna da matsakaicin aikin launi, yayin da fitilu masu CRI da ke ƙasa da Ra50 suna da ƙarancin ma'anar launi. Saboda haka, yana da kyau a zaɓi na'urorin hasken wuta na LED tare da babban CRI.
2. Guji Glare:
Glare yana tasiri sosai akan ingancin hasken kuma yakamata a rage shi. Zaɓi fitilun da ba sa haskakawa. Da kyau, zaɓi kayan gyare-gyare tare da diffusers masu sanyi waɗanda ke fitar da taushi, ko da haske.
3. Gabaɗaya Ƙarfafa Hasken Haske na LED:
The “inganci mai haske” na ƙãrewar hasken LED shine jimlar haske mai haske da ke fitarwa ta LED a ƙarƙashin ƙimar ƙarfin lantarki da aka raba ta jimlar ƙarfin da aka cinye, auna a cikin lumens per watt (lm/W). Mafi girman wannan darajar, mafi kyawun tasirin ceton makamashi, da karancin wutar lantarki da ake amfani da su. Saboda haka, zaɓi na'urorin hasken wuta na LED tare da manyan lumens a kowace watt (zai fi kyau fiye da 80 lm/W; misali, kayan aiki tare da inganci na ≥85 lm / W zabi ne mai kyau).
4. LED Temperatuur Tashi:
Yawanci, wanda ya halatta zafin jiki Tashi don fitilun LED da ake amfani da su shine tsakanin 25 ℃ zuwa 30 ℃. Musamman, zafin jiki a kan heatsink na LED shine yanayin yanayi tare da haɓakar zafin da aka yarda. Wannan yana nufin, idan yanayin zafin jiki shine 37 ℃, zafin jiki a kan heatsink LED yakamata ya zama 67 ℃ (37℃+30 ℃). Idan ya zarce wannan, ana ɗaukar hawan zafin jiki mara yarda. Heat shine abokan gaba na aikin LED; ƙarancin zafi da aka samar, mafi girman ingancin hasken LED. Bugu da kari, haɓakar saurin zafin jiki akan heatsink yana nuna haɓakar haɓakar thermal da ƙarancin juriya na hasken wutar lantarki na LED.
5. LED Lifespan:
Hasken farko na sabon haske shine 100%. Tsawon lokaci, ingantaccen ingancin hasken zai ragu. Tsawon rayuwar LED shine lokacin da ake ɗauka don hasken sa ya ragu zuwa 70% na farkon juyi. A zahiri, mafi tsayi mafi kyau. Misali, LEDs daga sanannun alamun suna iya wucewa 30,000 hours, wanda ya dace musamman don manyan ayyukan hasken wuta.
Waɗannan su ne shawarwari don zaɓar fitilun da ke tabbatar da fashewar LED. Da fatan, wannan jagorar za ta taimaka maka wajen yanke shawara na ilimi.
