Title:
AUTOMOTIVE LIGHTING APPARATUS AND RELATIVE CONTROL METHOD
Document Type and Number:
Japanese Patent JP2021178626
Kind Code:
A
Abstract:
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
