Vehicle lamp system and active light adjustment method for a vehicle lamp system

An active light adjustment method for a vehicle lamp system, comprising:

• providing a vehicle lamp system, wherein the vehicle lamp system comprises a plurality of light-emitting devices and a sensor;
• sensing at least one traffic object ahead by the sensor;
• and
• based on a sensing signal transmitted from the sensor, determining whether the at least one traffic object falls within coordinate ranges of shadow regions wherein the shadow regions are generated in response to at least one part of the light-emitting devices being turned off, and reducing a brightness of the at least one part of the light-emitting devices or turning off the at least one part of the light-emitting devices in response to determining that the at least one traffic object falls within the coordinate ranges of the shadow regions,
• wherein the active light adjustment method further comprises step (a), step (b), step (c), or step (d),
• wherein the step (a) comprises:
• reducing a brightness of at least one adjacent light-emitting device of the light-emitting devices or turning off the at least one adjacent light-emitting device in response to determining that the at least one traffic object falls within the shadow regions generated in response to the at least one part of the light-emitting devices being turned off, wherein the at least one adjacent light-emitting device is adjacent to the at least one part of the light-emitting devices,
• wherein the step (b) comprises:
• based on the sensing signal transmitted from the sensor, determining whether the at least one traffic object falls within a gap between the shadow regions generated in response to the at least one part of the light-emitting devices being turned off, and reducing the brightness of the at least one part of the light-emitting devices corresponding to the shadow regions on both sides of the gap or turning off the at least one part of the light-emitting devices corresponding to the shadow regions on both sides of the gap in response to determining that the at least one traffic object falls within the gap between the shadow regions generated in response to the at least one part of the light-emitting devices being turned off,
• wherein the step (c) comprises:
• converting a coordinate of the at least one traffic object measured by the sensor into a coordinate of the at least one traffic object relative to the light-emitting devices and further determining whether the at least one traffic object falls within the shadow regions generated in response to the at least one part of the light-emitting devices being turned off, and
• wherein the step (d) comprises:
• alternately turning off the light-emitting devices, and capturing images of the shadow regions in front of the vehicle lamp system;
• converting rectangular coordinates of the shadow regions into angular coordinates;
• and
• storing a plurality of the angular coordinates of a plurality of the shadow regions corresponding to the light-emitting devices to determine whether the at least one traffic object falls within the shadow regions generated in response to the at least one part of the light-emitting devices being turned off.
