8.2 Tambayoyi da Aka fi yin

Q: Menene matsakaicin inganci (lumens kowace watt) na wannan LED?

A: Bayanin fasaha yana ƙayyade ƙarfin haske a cikin millicandelas, ba lumens ba. Don ƙididdige kusan lumens, dole ne a yi la'akari da kusurwar dubawa. Don kusurwar dubawa na digiri 120 da 2240 mcd, matsakaicin kwararar haske shine kusan lumens 6-8. A 93mW, wannan yana haifar da inganci kusan 65-85 lm/W.

Q: Zan iya tuƙi wannan LED da baturin mota 12V kai tsaye?

A: A'a. Ƙarfin lantarki na gaba kusan 3.1V ne. Haɗa shi kai tsaye zuwa 12V zai lalata shi nan take. Da'ira mai iyakance ƙarfin kwarara, kamar direba mai ƙarfi na layi na yau da kullun ko na'urar canza canjin canji, ya zama dole.

Q: Ta yaya zan zaɓi daidaitaccen kwandon shara na ƙarfi don aikace-aikacena?

A: Yi amfani da ƙimar ƙarfin haske mafi ƙanƙanta na kwandon shara, ba matsakaici ko mafi girma ba. Ƙirar tsarin gani don cika buƙatun haske ko da tare da LED daga mafi ƙanƙancin kwandon shara da kuka yarda a cikin odar siyayya. Wannan yana tabbatar da yawan amfanin ƙasa da daidaito.

Q: Menene ma'anar \"Corrosion Robustness Class A1\"?

A> Wannan rarrabuwa, wanda masana'anta ko ƙayyadaddun abokin ciniki suka ayyana sau da yawa, yana nuna LED ya wuce takamaiman gwaje-gwajen lalata da aka hanzarta (misali, gwaje-gwajen iskar gas da aka haɗa) waɗanda ke kwaikwayi mawuyacin yanayi, suna tabbatar da cewa kunshe da jagororin suna tsayayya da lalata a tsawon rayuwar samfurin.
