Summary: | To provide a vehicle lighting that integrates a clearance lamp and a turn signal lamp.SOLUTION: A drive circuit 210 becomes active on the basis of a first lighting instruction signal S1 and a second lighting instruction signal S2, and outputs a constant current drive current Ifrom an output terminal. A distribution circuit 220 forms a current path such that the drive currents Iflows through a second light source 120 in an input state of the second lighting instruction signal S2, and forms the current path such that the drive currents Iflow through the first light source 110 in non-input state of the second lighting instruction signal S2.SELECTED DRAWING: Figure 2
【課題】クリアランスランプとターンシグナルランプを統合した車両用灯具を提供する。【解決手段】駆動回路210は、第1点灯指示信号S1と第2点灯指示信号S2とにもとづいてアクティブとなり、出力端子から定電流の駆動電流ILEDを出力する。分配回路220は、第2点灯指示信号S2の入力状態において、駆動電流ILEDが第2光源120に流れるように電流経路を形成し、第2点灯指示信号S2の無入力状態において、駆動電流ILEDが第1光源110に流れるように電流経路を形成する。【選択図】図2 |
