Yini i-Blacklight Flashlight? I-flashlight emnyama iyidivayisi ephathwayo eyenzelwe ukukhipha ukukhanya kwe-ultraviolet, imvamisa ku- UVA uhla (cishe 320-400 nm). Ngoba lokhu kukhanya kwe-UV kuhlala ngaphandle kwe-spectrum ebonakalayo, abantu abakuboni ngqo, kepha lapho kukhanya ezintweni ezithile, lezo zinto zi-fluoresce - zikhiqiza ukukhanya okubonakalayo ngemibala egqamile. Amathoshi amnyama anamuhla asebenzisa ubuchwepheshe be-UV-LED - ama-diode asebenzayo, ahlala isikhathi eside akhiqiza ukukhishwa okungaguquguquki kwe-ultraviolet ngokusetshenziswa kwamandla okuncane. Lawa ma-LED aklanyelwe ukukhiqiza noma 365 nm (i-UV ehlanzekile kakhulu) noma 395 nm (i-UV exutshwe ne-violet ebonakalayo) ama-wavelengths, ngayinye inezinzuzo ezihlukile zezicelo ezahlukahlukene. Isebenza kanjani i-Blacklight Flashlight? Ukusebenza kwe-flashlight emnyama kuhilela izingxenye ezimbalwa eziyisisekelo nezimiso: 1. Ukukhishwa ...
