Lata hte lang ai UV curing lamp ni gaw, ultraviolet (UV) nhtoi hpe lang nna, tsi mawan ni hpe shabyin ya ai, lawan ai hku n-gun ja shangun ai coating, shing nrai, ink ni hpe shabyin ya ai jak ni re. Shanhte a madung bungli galaw ai ladat gaw, nhtoi htoi ai n-gun atsam (photochemical reaction) rai nga ai: UV nhtoi htoi ai gaw, nhtoi htoi ai hpe shabyin ya nna, dai gaw, dai arai hta lawm ai monomers (sh) oligomers ni hpe polymerize (sh) crosslink byin shangun nna, hpang jahtum e, ngang kang ai shingnip langai mi hpe shabyin ya ai.
Ndai jak ni gaw, mercury wan n-gun (sh) LED nhtoi n-gun ni hpe lang nna, UV n-gun grai law ai majaw, mercury wan n-gun hpe grai lang ai. Lamp kata na mercury nbung hku nna current lai wa ai shaloi, mercury atom ni gaw n-gun kaba ai-masa de shadut hkrum ai. Dai hpang shanhte gaw npu na masa de bai galai shai wa nna, 365nm (UVA), 385nm, shing nrai 405nm grup yin hta n-gun rawng ai UV nhtoi hpe shapraw ya ai. Ndai UV n-gun ni gaw, nhtoi hpe n-gun jaw ai ni (benzophenone (sh) benzoin ether zawn re ai) ni hpe kaja wa shamu shamawt shangun nna, shanhte hpe n-gun n rawng hkra galaw ya nna, free radicals (sh) cations ni hpe shabyin ya ai, dai gaw resin arung arai hpe polymerization byin shangun ai.
Lata hte lang ai UV curing lamp ni hpe htaw sa mai ai hte hkrak hkrak hkang lu na matu galaw da ai rai nna, law malawng gaw, n bung ai arung arai ni a curing ra kadawn ai lam ni hpe hkan nna, n-gun pru ai lam hte n-gun dat ai aten hpe galai shai mai ai.
