CONTROL DEVICE FOR VEHICLE LAMP FITTING AND VEHICLE LAMP FITTING

To suppress scale-up of the configuration of a power supply unit and suppress the manufacturing cost.SOLUTION: A control device 100 for a vehicle lamp fitting 200 controls a light emitting unit 40 provided with a plurality of light emitting areas AR having a plurality of light sources 50 arranged vertically and horizontally, and includes one power supply unit 10 that serves as a current supply source for the plurality of light sources 50 in the plurality of light emitting areas AR, and a power supply selection unit 20 for supplying a current from the power supply unit 10. When receiving a command for causing two or more light emitting areas AR out of the plurality of light emitting areas AR to emit light in the same period, the power supply selection unit 20 supplies the current from the power supply unit 10 to a plurality of light sources 50 of the commanded light emitting areas AR time-divisionally for each light emitting area AR.SELECTED DRAWING: Figure 1 【課題】電源部の構成が大掛かりとなることを抑制し、製造コストを抑制する。【解決手段】制御装置１００は、縦横に配置される複数の光源５０を有する発光エリアＡＲが複数設けられた発光部４０を制御する車両用灯具２００の制御装置１００であって、複数の発光エリアＡＲにおける複数の光源５０に対して電流の供給源となる１つの電源部１０と、複数の発光エリアＡＲのうち２つ以上の発光エリアＡＲを同じ期間に発光させる旨の指令を受けた場合、指令を受けた発光エリアＡＲの複数の光源５０に対して発光エリアＡＲごとに時分割して電源部１０からの電流を供給させる電源選択部２０とを備える。【選択図】図１
