ランプの照明装置。[Scope of Claim for Utility Model Registration] A background illumination optical system is provided that guides photographing light from a photographing light source to the subject's eye and illuminates the surrounding area of the photographed area, and a slit light beam that directs the photographic light from the photographic light source to the photographic subject area. A photo slit lamp illumination in which an observation light source is provided on the optical axis of a projection optical system, and the observation light is guided to the subject's eye as if it were generated from the photographing light source and is projected as a slit light during observation. The apparatus is characterized in that an observation illumination optical system is provided which guides a part of the observation light to the background illumination optical system through the photography light source as if it were generated from the photography light source during observation. Slits lamp lighting device.
