Abstract

A laser head lamp for a vehicle includes: a plurality of lamp modules each comprising a laser diode and configured to output at least one of a low beam or a high beam; at least one processor; and a computer-readable medium coupled to the at least one processor having stored thereon instructions which, when executed by the at least one processor, causes the at least one processor to perform operations comprising: acquiring total operation time of each of the plurality of lamp modules; and controlling, based on the acquired total operation times, at least one first lamp module among the plurality of lamp modules differently from at least one second lamp module among the plurality of lamp modules.

Claims (34)

1. A laser head lamp for a vehicle, comprising:

a first lamp module group including a plurality of lamp modules each comprising a laser diode and configured to generate a low beam;

a second lamp module group including a plurality of lamp modules each comprising a laser diode and configured to generate a high beam; and

at least one processor configured to:

turn on at least one of lamp modules of the first lamp module group and at least one of lamp modules of the second lamp module group to generate the low beam,

acquire total operation time of each of the plurality of lamp modules of the first lamp module group and the plurality of lamp modules of the second lamp module group, and

turn on, based on the acquired total operation times, at least one of the plurality of lamp modules of the first lamp module group and at least one of the plurality of lamp modules of the second lamp module group to generate the low beam.

2. The laser head lamp according to claim 1 , wherein the at least one processor is further configured to:

determine, based on the total operation time of each of the lamp modules of the first lamp module group and the second lamp module group, a combination of lamp modules among the first one or more lamp modules and the second one or more lamp modules to be turned on to generate the low beam.

3. The laser head lamp according to claim 1 , wherein the at least one processor is further configured to:

acquire a temperature of each of the plurality of lamp modules of the first lamp module group and a plurality of lamp modules of the second lamp module group; and

turn on, further based on the acquired temperatures, at least one of lamp modules of the first lamp module group and at least one of lamp modules of the second lamp module group to generate the low beam.

4. The laser head lamp according to claim 1 , further comprising:

an interface unit,

wherein the at least one processor is further configured to:

receive, through the interface unit, object information associated with an object located outside of the vehicle, and

determine a first lamp module among the plurality of lamp modules of the first lamp module group and the plurality of lamp modules of the second lamp module group to be turned on to illuminate the object.

5. A laser head lamp for vehicle, comprising:

a plurality of left-hand lamp modules each comprising a laser diode and configured to output at least one of a left-hand low beam or a left-hand high beam;

a plurality of right-hand lamp modules each comprising a laser diode and configured to output at least one of a right-hand low beam or a right-hand high beam; and

at least one processor configured to:

control at least one of the plurality of left-hand lamp modules and at least one of the plurality of right-hand lamp modules to generate a left-hand low beam, and

control at least one of the plurality of left-hand lamp modules and at least one of the plurality of right-hand lamp modules to generate a right-hand low beam.

6. A vehicle comprising:

a plurality of wheels;

a power source configured to drive at least one of the plurality of wheels; and

a laser head lamp,

wherein the laser head lamp comprises:

a first lamp module group including a plurality of lamp modules each comprising a laser diode and configured to generate a low beam;

a second lamp module group including a plurality of lamp modules each comprising a laser diode and configured to generate a high beam; and

at least one processor configured to:

turn on at least one of the plurality of lamp modules of the first lamp module group and at least one of the plurality of lamp modules of the second lamp module group to generate the low beam,

acquire total operation time of each of the plurality of lamp modules of the first lamp module group and the plurality of lamp modules of the second lamp module group, and

turn on, based on the acquired total operation times, at least one of the plurality of lamp modules of the first lamp module group and at least one of the plurality of lamp modules of the second lamp module group to generate the low beam.
