Claims (1)
ービームフィラメントの一方のフィラメントが断線した
際、それを検出して断線していない他方のフィラメント
に代替して点灯できるようにした自動車用前照灯の断線
補償回路であつ・ て、前照灯の点灯信号と基準電圧と
の比較によって［ｉ線検出するハイビームフィラメント
、ロービームフィラメント毎に設けた前照灯断線検出回
路と、該断線検出回路の出力信号とライティングスイッ
チの出力信号とから前照灯の断線側フィラメントを判別
する判別回路と、該制御回路からの出力によって断線し
ていない側のフィラメントに電流供給する前照灯駆動回
路と、前記断線検出回路の出力によって駆動され、前照
灯の断線状態を知らせる警報回路とを備えて成ることを
特徴とする自動車用前照灯の断線補償回路。When one of the high-beam filament and low-beam filament that makes up an automobile headlamp breaks, it can be detected and the other unbroken filament can be used instead to light the car. The compensation circuit compares the headlight lighting signal with a reference voltage and detects the output signal of the headlight disconnection detection circuit provided for each high beam filament and low beam filament that detects the i-line, and the output signal of the disconnection detection circuit. a determination circuit that determines which filament is on the broken side of the headlamp based on the output signal of the lighting switch; a headlamp drive circuit that supplies current to the filament on the non-broken side based on the output from the control circuit; and the breakage detection circuit. What is claimed is: 1. A disconnection compensation circuit for a headlamp for an automobile, comprising: an alarm circuit driven by the output of the headlamp to notify a disconnection state of the headlamp.
