Problems solved by technology

[0004] In the vehicle lamp described in Patent Document 1, it is necessary to have a drive device for changing the irradiation direction left and right and a drive device for changing it up and down. In addition, since the lamp unit is not directly supported on the lamp body It is supported by brackets, so it is difficult to avoid cost increases due to the increase in the number of components, the increase in component costs, and the increase in assembly processes

Embodiment Construction

[0032] Next, the best mode for carrying out the vehicle lamp of the present invention will be described with reference to the drawings. In addition, in the illustrated embodiment, the present invention is applied to a vehicle headlamp.

[0033] First, a first embodiment is shown in FIGS. 1 to 4 .

[0034] The outline of a vehicle headlamp will be described with reference to FIG. 1 .

[0035] The vehicle headlamp 10 is formed by arranging a lamp unit 30 so as to be rotatable up, down, and left and right in a housing 20 having a lamp chamber 21 which is a substantially airtight space. The casing 20 is formed by covering the front opening of a container-shaped lamp body 22 which is open at the front with a transparent cover 23 .

[0036] In the vehicle headlamp 10 shown in the figure, the lamp unit 30 is supported on the lamp body 22 via the bracket 40 so that it can tilt up and down and left and right. Supported on the lamp body 22 .

[0037] In addition, a biaxial actuator ...

Abstract

The present invention provides a lamp for a vehicle, which can change the irradiation direction in any direction up, down, left and right, reduces the number of parts, and can accurately control the irradiation direction without applying an extra load to the drive unit. The vehicle headlamp (10) has: a lamp unit (30), which is arranged in a lamp chamber (21) formed by a lamp body (22) and a transparent cover (23) closing the front side of the lamp body, and facing forward irradiating light; and an irradiating direction adjusting device (50), which makes the lamp unit tilt up and down and left and right, and the lamp unit is suspended and supported in the lamp room in a state of being able to move up and down, left and right, and the irradiating direction adjusting device has an output shaft ( 51), which can move in the front-back direction and rotate in the left-right direction at the same time. The output shaft is connected to the lower end of the lamp unit, and the rotation in the left-right direction of the output shaft can be transmitted to the lamp unit. Rotation occurs between the axis and the luminaire unit.

Description

technical field [0001] The invention relates to a novel vehicle lamp. Specifically, it relates to a vehicular lamp capable of changing the irradiation direction in any direction of up, down, left and right. Background technique [0002] Among vehicle lamps, for example, vehicle headlamps, there is a lamp capable of changing the irradiation direction in any direction of up, down, left and right. [0003] In the vehicle lamp described in Patent Document 1, the lamp unit is supported on the bracket so that it can tilt left and right, and the bracket is supported on the lamp body so that it can tilt up and down. Left and right tilting movement of the light unit and up and down tilting movement of the bracket. [0004] In the vehicle lamp described in Patent Document 1, it is necessary to have a drive device for changing the irradiation direction left and right and a drive device for changing it up and down. In addition, since the lamp unit is not directly supported on the lamp...
