To execute temperature derating control with no hindrance, by suppressing an increase in costs of a vehicular lamp fitting, and after satisfying a request received by a plurality of functions (lighting modes) set in the vehicular lamp fitting.SOLUTION: A control device 29 of a vehicular lamp fitting 1 executes temperature derating control of the vehicular lamp fitting 1 comprising a lighting part 10 for lighting in a plurality of lighting modes, and one temperature detection part 30 for detecting a temperature inside or around a lamp chamber. The control device comprises: a non-volatile memory part 23 for storing a plurality of pieces of temperature derating information regulated by a temperature inside or around a lamp chamber, and electric power inputted to the lighting part 10, for each lighting mode of the lighting part 10; and a power control part 22 for controlling electric power inputted to the lighting part 10, in accordance with a lighting mode of the lighting part 10, a temperature inside or around a lamp chamber detected by the temperature detection part 30, and the temperature derating information stored in the non-volatile memory part 23.SELECTED DRAWING: Figure 2

    【課題】車両用灯具のコストの上昇を抑制し、車両用灯具に設定された複数の機能(点灯態様)が受ける要求を満たしたうえで、温度ディレーティング制御を支障なく実行する。【解決手段】複数の点灯態様で点灯する点灯部10と、灯室の内部又は周囲の温度を検出する一つの温度検出部30とを備える車両用灯具1の温度ディレーティング制御を実行する車両用灯具1の制御装置29であって、点灯部10の点灯態様毎に、灯室の内部又は周囲の温度と、点灯部10に入力される電力とにより規定された複数の温度ディレーティング情報を記憶する不揮発性メモリ部23と、点灯部10の点灯態様と、温度検出部30により検出された灯室の内部又は周囲の温度と、不揮発性メモリ部23に記憶された温度ディレーティング情報とに応じて、点灯部10に入力される電力を制御する電力制御部22とを備える。【選択図】図2
