Description

Lamp for vehicle

The present invention relates to a vehicle lamp, and more specifically, to a vehicle lamp whose aiming is adjustable.

Generally, vehicles are equipped with vehicle lamps that have a lighting function to easily identify objects located around the vehicle when driving at night and a signal function to inform other vehicles or road users of the vehicle's driving status.

For example, headlights that illuminate the front to secure the driver's field of vision, brake lights that turn on when the brakes are applied, turn signals that turn on right or left, and reversing lights that turn on when reversing, use lamps to directly emit light. There are vehicle lamps that operate in this way, and in addition, reflectors, etc. that function by reflecting light so that the vehicle can be easily recognized from the outside are installed on the front and rear of the vehicle.

Vehicle lamps must emit light in a set direction to secure visibility or comply with related laws and regulations. However, the irradiation direction of light may deviate from the set direction due to the coupling relationship with surrounding components or the unique characteristics of each component constituting the vehicle lamp.

Accordingly, there is a need for an invention that allows the direction of light irradiation to be adjusted so that the light is irradiated in a set direction.
