PROBLEM TO BE SOLVED: To properly determine mixture of specific light-emitting parts when the specific light-emitting parts having different characteristics are mixed in a light-emitting unit.SOLUTION: A control device 20 for controlling a light-emitting unit 10 having a plurality of light-emitting parts 11a to 11d includes; a current acquisition part 222 for acquiring a current value when turning on the light-emitting parts 11a to 11d; and a determination part 224 for determining whether or not the specific light-emitting part is included in the light-emitting parts 11a to 11d based on the difference between the current value at the time of starting light emission of the light-emitting parts 11a to 11d and the current value at the time of stationary light emission.SELECTED DRAWING: Figure 2
【課題】発光ユニット中に特性が異なる特定の発光部が混在している場合に、特定の発光部の混在を適切に判別する。【解決手段】複数の発光部11a〜11dを有する発光ユニット10を制御する制御装置20は、発光部11a〜11dを発光させる際の電流値を取得する電流取得部222と、発光部11a〜11dの発光開始時の電流値と定常発光時の電流値との差に基づいて、発光部11a〜11d中に特定の発光部が含まれているか否かを判定する判定部224と、を備える。【選択図】図2
