The present invention relates to an inspection lighting system including a split light emitting type inspection lighting device, and a control device for controlling the inspection lighting device.

In recent years, for example, when inspecting the surface of a product (work) in a factory or the like, a so-called split light emitting type inspection lighting device having a ring-shaped light emitting surface divided into a plurality of individually dimmable light emitting regions has been used. May be used. In this split light emitting type inspection lighting device, each light emitting region is configured to emit light independently of each other according to a predetermined light emitting sequence including a plurality of steps. Thereby, for example, by irradiating the work with light in order from different directions and processing the captured image, surface defects can be extracted with good contrast.

By the way, when such a split light emitting type inspection lighting device is used, the adjustment of each light emitting area set for each step is adjusted so that the user can confirm and adjust the setting of the light emitting sequence of a plurality of light emitting regions. A setting screen showing a light emission mode such as a light value may be displayed on the display. For example, Patent Document 1 discloses such a setting screen in which the light emitting modes for all steps of each light emitting region are listed in a matrix by characters such as numbers. The user looks at the setting screen, confirms the light emission sequences of the plurality of light emission regions, and adjusts them.
