Light intensity adjustment device, light intensity adjustment system and light intensity adjustment method

摘要

PROBLEM TO BE SOLVED: To provide a light amount adjusting device, a light amount adjusting system and a light amount adjusting method capable of stabilizing sterilization performance even if the light emitting intensity of a light emitting element varies. SOLUTION: The light amount adjusting device 3 is an element that detects the amount of ultraviolet light emitted by a light emitting element 121 during an adjustment operation for adjusting the light emitting state of a light emitting element 121 that emits ultraviolet rays irradiating an object to be sterilized. Ultraviolet light emission having a light amount measuring device 32 having a light amount measuring element 321 whose output signal signal level with respect to the detected ultraviolet light amount is calibrated and controlled, and a light emitting element management circuit 11 for managing the operating state of the light emitting element 121 and the light emitting element 121. It includes a light amount control device 31 that controls the light emitting element management circuit 11 based on the detection result of the light detection element 321 during the adjustment operation in the device 1 to control the light amount of the light emitting element 121.
