To provide a lighting fixture system for a vehicle that uses a liquid crystal element and can reliably radiate light even under an extremely low-temperature environment.SOLUTION: A device for controlling a lighting fixture for a vehicle which includes a light source 40 and a liquid crystal element 45 controls the liquid crystal element 45 to be in a light-shielding state and controls the light source 40 in a lighting state to warm the liquid crystal element 45 using light discharged from the light source 40 when estimating that the temperature of the liquid crystal element 45 is lower than a predetermined reference.SELECTED DRAWING: Figure 2
【課題】極低温の環境下でも確実に光照射を行うことができる、液晶素子を用いる車両用灯具システムを提供する。【解決手段】光源40と液晶素子45を含んで構成される車両用灯具であって、液晶素子45の温度が所定の基準よりも低いと推定される場合に、液晶素子45を遮光状態に制御するとともに光源40を点灯状態に制御して、液晶素子45を光源40から放出される光によって加温する。【選択図】図2
