Claims

[Claims for Utility Model Registration] (1) A device for illuminating a glossy curved surface of an object for observation from a direction substantially normal to the surface, (a) (b) an annular light source disposed in the middle, the central axis of which is approximately a line connecting the object and the observation device; (c) two light-transmitting cylindrical members having cylindrical light-diffusing properties arranged in concentric circles; (c) provided so as to close the observation device side opening of the light-transmitting cylindrical members; (d) a reflective member having a reflective surface on the object side and a hollow portion in the center; (d) disposed between the light source and the translucent cylindrical member on the side closer to the light source, and configured to absorb light from the light source; A partial light shielding member that partially blocks light only in a certain direction of the exterior inspection lighting device. (2) In the utility model registration claim described in claim 1, the annular light source includes an annular light emitting body, a cylindrical reflecting member installed on the outside of the light emitting body, and a cylindrical reflecting member installed on the underside of the light emitting body. 1. A lighting device for visual inspection, comprising: a light-transmitting member having a light-diffusing property in the form of a plate-like annular ring.
