To solve a problem in which it is necessary to adjust and memorize a lighting pattern such as a total lighting time and a dimming time, which are different for a vehicle with different flashing speeds, and blinking pattern control cannot be performed with input signals alone, and additional connection lines such as a power supply for the control device are required in lighting control attempted to suppress the rapid brightness changes characteristic of semiconductor light emitting elements and reduce irritation and discomfort to viewers.SOLUTION: A voltage application time from a vehicle to a lamp is measured, light emission control is performed using the brightness increase, maximum brightness, and dimming times calculated from that time. Additionally, by using the voltage applied to a lamp from the vehicle as a power source for a control unit, only two signal lines are required.SELECTED DRAWING: Figure 1
【課題】半導体発光素子特有の急激な輝度変化を抑え視認者への刺激・違和感軽減するために試みられている点灯制御は、点滅速度の異なる車両において各々に異なる全点灯時間、減光時間などの点灯パターンを調整、記憶する必要があるほか、入力信号だけでは点滅パターン制御を行うことが出来ず、制御装置用電源など追加の接続線が必要となる。【解決手段】車両からの灯具へ印加される電圧印加時間の計測を行い、その時間から算出した増光・最大輝度・減光時間にて発光制御を行う。また、車両より灯具へ印加される電圧を制御部の電源として使用することで信号線の2本の配線のみで完結させる。【選択図】図1
