According to research, it found that blue light may cause significant effects on suppressing melatonin. For this reason, a lighting device capable of reducing the phenomenon of melatonin suppression is disclosed in the present invention, the lighting device comprises: a lighting device, capable of emitting a visible light； and a light-filtering device, which is close to the lighting device, wherein when the lighting device emits the visible light, the light-filtering device is able to filter a blue light component of the visible light, so as to reduce the blue light component within the visible light lighted by the lighting device, then the effects on suppressing the melatonin caused by the visible light are reduced.經由研究發現，藍光波長對於褪黑激素之抑制現象，係具有重大之影響，因此，本發明揭露一種可減緩褪黑激素抑制現象之照明裝置，係包括：一發光元件，可發出一可見光；以及一濾光元件，係鄰近於該發光元件，當發光元件發出該可見光時，該濾光元件可過濾可見光之一藍光成份，以減少發光元件所發出之可見光之該藍光成份，進而減緩可見光對於褪黑激素抑制現象之影響。
