摘要:
A lighting apparatus with an image-projecting function that is convenient for a user is provided. It includes: an illuminating unit that emits illumination light; a projection-type image display unit that emits image-projecting emission light for projecting an image; and a sensor that emits operation-detecting light for operation detection and that is capable of detecting an operation by an operation object in a range including an image projection area of the projection-type image display unit, and is configured so that the image-projecting light, and the operation-detecting emission light have respective different wavelength distribution characteristics, and regarding a light amount in the wavelength range of light used by the sensor for the operation detection, a light amount of the operation-detecting light is the largest among those of the illumination light, the image-projecting emission light, and the operation-detecting light.
