PROBLEM TO BE SOLVED: To provide: a vehicle lighting system, even in the case where a voltage applied to the vehicle lighting system decreases, capable of securing a required total luminous flux and capable of suppressing fluctuation of the total luminous flux; and a vehicle lamp.SOLUTION: A vehicle lighting system according to an embodiment includes: a first circuit portion that has at least one light emitting element and a first resistor connected in series to the light emitting element; a second circuit portion that is connected in parallel to the first circuit portion and has at least a control unit; and a third circuit portion that is connected in series to the first circuit portion and the second circuit portion, and has at least one light emitting element. The control unit measures an input voltage and causes a current to flow through the third circuit portion in the case where the measured input voltage is a predetermined value.SELECTED DRAWING: Figure 6

    【課題】車両用照明装置に印加される電圧が低下した場合であっても、必要となる全光束を確保することができ、且つ、全光束の変動を抑制することができる車両用照明装置および車両用灯具を提供することである。【解決手段】実施形態に係る車両用照明装置は、少なくとも1つの発光素子と、前記発光素子に直列接続された第1の抵抗と、を有する第1回路部と;前記第1回路部と並列接続され、少なくとも制御部を有する第2回路部と;前記第1回路部および前記第2回路部と直列接続され、少なくとも1つの発光素子を有する第3回路部と;を具備している。前記制御部は、入力電圧を測定し、前記測定された前記入力電圧が所定の値となった場合には、前記第3回路部に電流を流す。【選択図】図6
