Abstract
Particular embodiments may provide for a method of providing illumination for a vehicle. A signal to activate a headlamp assembly for a vehicle may be sent. The headlamp assembly may comprise a laser-based lamp positioned to provide high-beam illumination, including a plurality of beam subfields, and a light sensor configured to capture images of illuminated objects, wherein the light sensor is capable of sensing objects illuminated by visible-spectrum light. A focal region for the high-beam illumination may be determined based on images captured by the light sensor. Instructions to configure the laser-based lamp to modify a distribution of the high-beam illumination to increase brightness of one or more beam subfields of the high-beam illumination within the focal region may be sent.
Claims20
A method of providing illumination for a vehicle, comprising:
- sending, by one or more control modules of the vehicle, a signal to activate a headlamp assembly for the vehicle, the headlamp assembly comprising:
- a laser-based lamp positioned to provide high-beam illumination, wherein the high-beam illumination includes a beam field of light comprising a plurality of beam subfields;
- and
- a light sensor configured to capture images of illuminated objects, wherein the light sensor is capable of sensing objects illuminated by visible-spectrum light;
- determining, by the one or more control modules and based on images captured by the light sensor, a focal region for the high-beam illumination;
- and
- sending, by the one or more control modules, instructions to configure the laser-based lamp to modify a distribution of the high-beam illumination to increase a brightness of one or more beam subfields of the high-beam illumination within the focal region.
A system including one or more computing devices, comprising:
- one or more non-transitory computer-readable storage media including instructions;
- and
- one or more processors coupled to the one or more storage media, the one or more processors configured to execute the instructions to:
- send, by one or more control modules of the vehicle, a signal to activate a headlamp assembly for a vehicle, the headlamp assembly comprising:
- a laser-based lamp positioned to provide high-beam illumination, wherein the high-beam illumination includes a beam field of light comprising a plurality of beam subfields;
- and
- a light sensor configured to capture images of illuminated objects, wherein the light sensor is capable of sensing objects illuminated by visible-spectrum light;
- determine, by the one or more control modules and based on images captured by the light sensor, a focal region for the high-beam illumination;
- and
- send, by the one or more control modules, instructions to configure the laser-based lamp to modify a distribution of the high-beam illumination to increase brightness of one or more beam subfields of the high-beam illumination within the focal region.
A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of one or more computing devices, cause the one or more processors to:
- send, by one or more control modules of the vehicle, a signal to activate a headlamp assembly for a vehicle, the headlamp assembly comprising:
- a laser-based lamp positioned to provide high-beam illumination, wherein the high-beam illumination includes a beam field of light comprising a plurality of beam subfields;
- and
- a light sensor configured to capture images of illuminated objects, wherein the light sensor is capable of sensing objects illuminated by visible-spectrum light;
- determine, by the one or more control modules and based on images captured by the light sensor, a focal region for the high-beam illumination;
- and
- send, by the one or more control modules, instructions to configure the laser-based lamp to modify a distribution of the high-beam illumination to increase brightness of one or more beam subfields of the high-beam illumination within the focal region.
