器具。 A lighting device comprising a light source that emits visible light and a reflector that reflects the visible light and directs it toward a surface to be irradiated, wherein the reflector is configured to emit ultraviolet rays and infrared rays onto the substrate surface on its reflection side. A visible light reflective multilayer film is provided on the film, which is made by alternately laminating a material with a high refractive index and a material with a low refractive index. A lighting device for growing plants, characterized in that the film has a peak wavelength value of visible light reflectance characteristics that almost matches a peak wavelength value of a photosynthetic reaction curve of the plant.
