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. |
