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 light-emitting device being able to emit a visible light; and a light-filtering device being close to the light-emitting device, wherein when the light-emitting 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 emitted by the light-emitting device, then the effects on suppressing the melatonin caused by the visible light are reduced.
