A lamp for a vehicle includes: a light generation unit having an array module with a plurality of micro Light Emitting Diode (micro-LED) elements; at least one processor; and a computer-readable medium having stored thereon instructions that, when executed, cause the at least one processor to perform: controlling the light generation unit to form a first light distribution pattern that, when projected on a vertical plane at a first distance from the light generation unit, includes a plurality of zones having different luminous intensities. Controlling the light generation unit to form the first light distribution pattern includes: controlling at least one first micro-LED element to generate a first luminous intensity at a first zone of the first light distribution pattern; and controlling at least one second micro-LED element to generate a second luminous intensity at a second zone of the first light distribution pattern.
