PROBLEM TO BE SOLVED: To provide a lamp body control device and a lamp body lighting system capable of preventing faulty lighting of the lamp body due to a leak current, while suppressing an increase in the size.SOLUTION: A lamp body control device comprise a level adjusting part for: comparing a signal level of a signal received from an output terminal for driving, with a preset threshold value so as to detect a leak current occurring at a lamp body side; and converting the signal level of the signal to a second level if a leak current is detected, and outputting the second level signal to an input part.SELECTED DRAWING: Figure 1
【課題】サイズの増大を抑制し、リーク電流による灯体の誤点灯を防止可能な灯体制御装置及び灯体点灯システムを提供する。【解決手段】駆動用出力端子からの信号レベルと、予め設定された閾値とを比較することで前記灯体側に生じるリーク電流を検出した場合には、前記信号レベルを前記第2レベルに変換し、前記第2レベルの信号を前記入力部に出力するレベル調整部と、を備える。【選択図】図1
