Idan ana buƙatar tsaftacewa bayan solder, yi amfani da kaushi masu dacewa waɗanda ba su lalata resin LED ba. Ajiye kayan a cikin jakunkun su na asali na hana danshi a zazzabi tsakanin -40°C da 100°C, a cikin yanayi mai ƙarancin danshi, kuma bi ka'idojin kula da ESD na yau da kullun.

7. Tambayoyin da ake yawan yi (Bisa ga Ma'auni na Fasaha)

7.1 Menene ainihin amfani da wutar lantarki?

A wurin aiki na yau da kullun na 150mA da matsakaicin V_Fna 3.0V, matsakaicin rushewar wutar lantarki shine 450mW (0.45W). Ainihin wutar lantarki zai dogara da takamaiman kwanten V_Fna LED da aka yi amfani da shi.

7.2 Zan iya tuƙi wannan LED a 180mA akai-akai?

Duk da yake matsakaicin matsayi shine 180mA, ci gaba da aiki a wannan matakin zai haifar da ƙarin zazzabi (P_d≈ V_F*180mA). Wannan yana buƙatar ingantaccen sarrafa zazzabi don kiyaye zazzabin junction ƙasa da 115°C. Don aminci da tsawon rayuwa, ana ba da shawarar yin aiki a ko ƙasa da shawararriyar 150mA.

7.3 Ta yaya zan zaɓi daidaitaccen CCT da CRI?

Zaɓi CCT bisa ga \"dumi\" da ake so na haske: 2700K-3000K don dumin fari (kamar na incandescent), 3500K-4500K don tsaka-tsakin fari, da 5000K-6500K don sanyin fari (kamar hasken rana). CRI na 80 (Ra) yana da kyau ga haskakawa na gabaɗaya. Don aikace-aikacen da bambancin launi ke da mahimmanci (misali, gidajen zane-zane, madubin kayan shafa), nemo nau'ikan tare da CRI 90 ko sama idan akwai a cikin wannan jerin.

7.4 Me ya haifar da tolerance na ƙarfin haske na ±11%?

Wannan tolerance yana lissafin bambance-bambancen masana'antu na yau da kullun a cikin guntu LED, aikace-aikacen phosphor, da marufi. Tsarin rarrabawa (misali, 80L5, 85L5) yana ba da ƙayyadadden kewayon a cikin wannan jimlar tolerance don daidaiton samarwa.
