To provide a lighting control technology capable of performing excellently sequential control, in a vehicle lighting fixture having light emission surfaces having each different size.SOLUTION: In a vehicle lighting fixture, each light emission surface 41-47 of a transparent material for guiding light emitted from LED light sources to a direction orthogonal to an arrangement direction of the LED light sources are shown schematically, and each light emitting state is shown by a pattern. Time passes downward in the figure. Lights from each light emission surface 41-47 turn on sequentially with good separability by performing such lighting control, to thereby achieve such sequential control that light flows smoothly from left to right in the figure.SELECTED DRAWING: Figure 5
【課題】大きさの異なる光出射面を有する車両用灯具においてシーケンシャル制御をより良好に行うことができる点灯制御技術を提供する。【解決手段】車両用灯具において、LED光源が出射する光をLED光源の配列方向と直交する方向に導く導光体の各光出射面41〜47を模式的に示し、かつ光を出射している状態を模様によって示している。図中下方向へ向かって時間が経過するものとする。このような点灯制御を行うことにより、各光出射面41〜47からの光が分離性よく順次点灯するため、光が図中で左から右へスムーズに流れるシーケンシャル制御を実現することができる。【選択図】図5
