Description
図5は実施形態1のランプ制御装置の電気系統のブロック構成図である。ここでは右ヘッドランプR-HLの構成を詳しく図示しているが、左ヘッドランプL-HLについては一部の図示は簡略化している。右ヘッドランプR-HLにおいて、ランプECU2は第1から第3のLED駆動回路部21,22,23を備えている。第1LED駆動回路部21は電圧レベルの第1ライン(CLライン)Lv1によりクリアランスランプユニット31に接続され、その光源31sとしてのLEDに発光用の電流を供給する。第2LED駆動回路部22は同じく電圧レベルの第2ライン(Loライン)Lv2によりロービームランプユニット32に接続され、その光源32sとしてのLEDに発光用の電流を供給する。第3LED駆動回路部23は電圧レベルの第3ライン(ADBライン)Lv3によりADBランプユニット33に接続され、その光源33sとしての多分割LEDに発光用の電流を供給する。
図6は実施形態2におけるランプ制御装置の電気系統のブロック構成図である。実施形態1と等価な部分には同一符号を付しており、詳細な説明は省略する。左右のヘッドランプL-HL,R-HLは同じ構成であり、それぞれ複合ランプユニット3とレベリングアクチュエータ4を備え、かつこれらがそれぞれのランプECU2により制御される構成であることは実施形態1と同様である。また、左右のヘッドランプの各ランプECU2は車両CANラインLc1により車両ECU1に接続されていることも実施形態1と同じである。
図8は実施形態3におけるランプ制御装置の電気系統のブロック構成図である。実施形態2と等価な部分には同一符号を付しており、詳細な説明は省略する。実施形態3は、1つのCAN通信回路部24AによってADB配光制御とレベリング制御をそれぞれ行なう構成とされている。すなわち、このCAN通信回路部24Aは、実施形態2の第1CAN通信回路部24と第2CAN通信回路部26の両機能を備えたものとして構成されている。そして、このCAN通信回路部24AはADBランプユニット33とレベリングアクチュエータ4のそれぞれにランプCANラインLc2により接続されている。
