PROBLEM TO BE SOLVED: To improve work efficiency for adjustment by automatically adjusting an emission angle, in a spotlight illuminating an object to adjust an emission angle of light from a light source to the object. SOLUTION: The spotlight 10 includes an illumination part 1 and a camera part 2. The illumination part 1 has a light source 3 and a lens part 4. The lens part 4 includes a zoom lens 41 condensing the light of the light source 3, and a lens drive part 42 adjusting the focus of the zoom lens 41. The camera part 2 includes an image information acquisition part 5 acquiring image information by imaging an object, and an information processing part 6 detecting the distance between the image information acquisition part 5 and the object based on the image information from the image information acquisition part 5. The lens drive part 42 adjusts the zoom lens 41 based on distance information between the image information acquisition part 5 and the object detected by the information processing part 6. Accordingly, the emission angle is automatically adjusted in accordance with the distance of the object or the like, and work efficiency for adjustment is improved even when the layout of a shop or the like is changed.
