PROBLEM TO BE SOLVED: To provide a lighting device for motor vehicles, which is arranged so that a scrolling effect can be obtained with a simple structure.SOLUTION: A light-emitting device includes a first electroluminescent module (2.1) and a second electroluminescent module (2.2) energized in series. Each electroluminescent module includes, in parallel: a first branch having a light source (3) having a first direct threshold voltage beyond which the light source is gated on; a second branch having an element (5) such that the voltage on the terminals of the element is less than the first direct threshold voltage of the light source; and a third branch having a timing module (6) that times a predetermined period and modifies, at the end of the predetermined period, an overall impedance of the second branch so that a voltage in the second branch is greater than the first direct threshold voltage of the light source. The predetermined period in the first electroluminescent module is less than that of the second electroluminescent module.SELECTED DRAWING: Figure 1

    【課題】簡易な構成で、スクロール効果を得る、車両用照明装置を提供する【解決手段】直列に通電される第1のエレクトロルミネセントモジュール(2.1)と第2のエレクトロルミネセントモジュー(2.2)を備える。各エレクトロルミネセントモジュールは、第1の直流閾値電圧を有する光源(3)と、第1の直流閾値電圧を超えると光源がゲートオンされる第1のブランチと、素子(5)の端子電圧が光源の第1の直流閾値電圧未満であるように備える第2のブランチと、所定期間のタイミングを図り、所定期間の終わりに第2のブランチにおける電圧が光源の第1の直流閾値電圧よりも大きくなるように第2のブランチの全インピーダンスを変更する、タイミングモジュール(6)を備える第3のブランチとを並列接続で備える。第1のエレクトロルミネセントモジュールにおける所定期間は、第2のエレクトロルミネセントモジュールにおける所定期間よりも短い。【選択図】図1
