Tata ki te tekau tau i muri i te whakaurunga mai, kei te tere haere te whakamahi a ngā kaitahuri tapanga i ngā waituhi UV LED ka taea te whakaora. Kei te whānui haere te māramatanga ki ngā painga o te waituhi i ngā waituhi UV mercury 'tūturu' – he pai ake, he tere ake te whakamaroke, he pai ake te pumau me te iti ake o ngā utu whakahaere. Hei tāpiri, kei te ngāwari haere te uru atu ki te hangarau i te mea kei te tuku ngā kaihanga perehi ki te whakauru i te whānuitanga o ngā rama roa ki ā rātou raina.
Heoi anō, he nui ake te hihiri mō ngā kaitahuri ki te whakaaro ki te huri ki te rama LED, nā te mea kei te whakaitihia ngā mōrearea me ngā utu o te mahi pera. Kei te āwhinahia tēnei e te taenga mai o tētahi whakatupuranga hou o ngā waituhi me ngā paninga 'rua-whakaora' ka taea te whakahaere i raro i ngā rama LED me te rama mercury, e āhei ai ngā kaitahuri ki te whakamahi i te hangarau i roto i ngā taahiraa, kaua i te ohorere.
Ko te rerekētanga matua i waenga i te rama mercury tikanga me te rama LED ko ngā roangaru e tukuna ana kia whakamaroke. Ka tukuna e te rama mercury-coal te pūngao puta noa i te whānuitanga i waenga i te 220 me te 400 nanometer (nm), ko ngā roangaru ia o ngā rama LED he whaiti ake i waenga i te 375nm me te 410nm, ā, ka eke ki te 395nm te teitei.
He rite tonu te whakamaroketanga o ngā waituhi UV LED ki ngā waituhi UV noa, engari he tairongo ki tētahi roangaru whaiti o te māramatanga. Nō reira, he rerekē rātou tetahi i tetahi nā te rōpū o ngā kaiwhakaoho whakaahua e whakamahia ana hei tīmata i te tauhohenga whakamaroke; he rite tonu ngā tae, ngā oligomer me ngā monomer e whakamahia ana.
He pai ake te kounga, te haumaru, me te taiao o te whakamaroke UV LED i te whakamaroke tikanga. Kāore e whakamahia he mercury, he ozone rānei i roto i tēnei tukanga, nō reira kāore he pūnaha tango e hiahiatia ana hei tango i te ozone mai i te mīhini tā.
He roa hoki te whai huatanga o tēnei rama. Ka taea te whakakā me te whakaweto i te rama LED, kāore he hiahia mō te wā whakamahana, whakamatao rānei, kia pai ai te mahi mai i te wā e whakakāhia ana. Kāore he hiahia mō ngā arai hei tiaki i te papa mēnā ka whakawetohia te rama.
