摘要： A lighting apparatus of vehicles may include a light source unit of emitting light; a first reflection unit of reflecting light incident from the light source unit to discharge the reflected light outside the first reflection unit; a second reflection unit rotatably provided between the light source unit and the first reflection unit to reflect light for allowing light emitted by the light source unit to move to the first reflection unit or blocking the light such that the light is not moved to the first reflection unit and reflecting the light at a position different from the first reflection unit to discharge the light outside depending on a rotational position of the second reflection unit; and a driving unit connected to the second reflection unit and configured of adjusting the rotational position of the second reflection unit.

摘要： A variable headlamp apparatus for a vehicle is capable of realizing various lighting functions by switching positions of the plurality of optical units only with a single drive unit. The variable headlamp apparatus includes: an optical unit having an emitter to emit light; a guide unit installed with the optical unit to guide a position of the optical unit to a fixed path; a link unit connected to the optical unit and including multiple links rotatably connected to each other to change the position of the optical unit; and a drive unit to rotate the links. In particular, the optical unit moves along the fixed path of the guide unit while switching a light irradiation direction of the emitter.

摘要： A rear lamp apparatus of a vehicle is provided. The rear lamp apparatus includes a light source configured to irradiate beams, a hologram lens configured to generate a specific image when the beams irradiated from the light source are incident thereto and a reflector disposed to position the beams of the light source incident thereto and reflect the beams irradiated from the light source to transmit the beams to the hologram lens. A shield is disposed between the light source and the hologram lens to block the beams irradiated from the light source to prevent the beams from being incident to the hologram lens. Accordingly, the rear lamp apparatus resolves distortion when a hologram image is formed and is advantageous in a layout by reducing a reproduction distance when a recording distance of the hologram image is increased.
