Abstract
A sequential lighting device of a lamp for a vehicle, may implement sequential lighting with one light source, reducing the cost and simplifying the structure. Furthermore, the sequential lighting is implemented by the rotation of a light guide, forming a slim lamp form, and the smooth lighting feeling is implemented, improving merchantability.
Claims16
A sequential lighting device of a lamp, the device comprising:
- a housing which is formed to extend linearly in an axial direction of the housing, and has a light source provided at an end portion of the housing;
- and
- a light guide which is formed to extend linearly in the axial direction of the housing, and mounted to the housing in the axial direction of the housing, wherein the light guide is rotatable in a circumferential direction of the light guide,
- wherein the light guide includes:
- an end portion mounted adjacent to the light source so that a light radiated from the light source is incident;
- and
- an emission portion through which the light is emitted, the emission portion being formed on a circumferential surface of the light guide, and formed to extend from a first side to a second side along the circumferential surface, and changing an emission position of the light according to a rotational position of the light guide, and
- wherein the emission portion has a plurality of optics which is arranged spirally from the first side to the second side along a rotation direction of the light guide.
