To provide an automotive lighting apparatus and a relative control method that increase the active safety of new lighting assemblies that use optical fibers to backlight a front half-shell of the light.SOLUTION: In an automotive lighting apparatus 1, a lighting assembly 4 includes: a radially emitting optical fiber 6 of given length; an electric collimated light source 5 which is located in front of a proximal end 6a of the optical fiber, and is adapted to direct, toward the proximal end, a collimated light beam that enters and travels inside the optical fiber; at least one proximal photometric sensor 8 which is arranged beside the collimated light source 5 and/or the proximal end of the optical fiber so as to capture/detect the light reflected/scattered on entering into the optical fiber; at least one distal photometric sensor 9 which is located in front of the distal end 6b of the optical fiber, and is adapted to capture/detect the light exiting from the distal end of the optical fiber; and an electronic control unit 7 which is adapted to command the collimated light source on the basis of signals coming from the proximal and distal photometric sensors.SELECTED DRAWING: Figure 2
【課題】ライトの前部ハーフシェルを背面光照明するために光ファイバを使用する新しい照明組立体の積極的な安全性を増す自動車用照明器具及びその制御方法を提供する。【解決手段】自動車用照明装置1において、照明組立体4は、所与の長さの放射発光光ファイバ6と、光ファイバの近位端6aの前に配置され、光ファイバへ進入し光ファイバ内部を通過する平行光線を、近位端へ向かって指向する電気コリメート光源5と、光ファイバの中へ進入するとき反射/散乱した光を捕捉/検出するようにコリメート光源5及び/又は光ファイバの近位端の横に配列される少なくとも1つの近位測光センサ8と、光ファイバの遠位端6bの前に配置され、光ファイバの遠位端から出る光を捕捉/検出する少なくとも1つの遠位測光センサ9と、近位測光センサ及び遠位測光センサからの信号に基づいてコリメート光源にコマンドを発する電子制御ユニット7とを含む。【選択図】図2
