The lighting device includes: a light-transmissive plate having an entrance surface; and an image projecting device that irradiates the entrance surface of the light-transmissive plate with image light. The image light passing through the light-transmissive plate is projected on an object. The image light emitted by the image projecting device includes light in a first wavelength range and light in a second wavelength range. Here, the light in the second wavelength range is longer in wavelength than the light in the first wavelength range. The light-transmissive plate absorbs or scatters the light in the first wavelength range more than the light in the second wavelength range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lighting device","description":"A lighting device is provided.
