A lamp for a vehicle includes an optical unit including a plurality of optical modules to form a specific beam pattern on a road surface, the beam pattern includes a first pattern area and a second pattern area more spaced apart from the optical unit than the first pattern area, the optical unit includes a first optical module to form the first pattern area and a second optical module to form the second pattern area, and the second pattern area is placed on an optical axis of the second optical module.

Lit image projection devices and lamp assemblies containing the same for generation of three dimensional images. A projection device of the present disclosure comprises one or more light sources, a rippled substrate defining a reflective surface, the reflective surface configured to reflect light source light from the one or more light sources as reflected light, and a first lenticular lens configured to receive the reflected light from the reflective surface, wherein the reflected light received by the first lenticular lens generates a three-dimensional lit image.

The present disclosure provides a projection lamp module and a headlamp device for a vehicle using the same, in which two headlamps implement the same brightness, images of the headlamps are maintained, and visibility of an image projected onto a road surface is improved even though even though a lamp having a lighting function of forming an image on a road surface is applied to any one of the headlamps for a vehicle.

A small-sized vehicle-mounted projector light system including an illuminating module having a light source, a collimating lens and a film arranged in sequence, and an imaging module; the imaging module includes a curved reflector being a concave mirror with positive focal power, and a first imaging lens. The main optical axis of the illuminating module passes through the reflective surface of the curved reflector, on one side of which the first imaging lens is positioned. The invention ensures an appropriate size of an one-way dimension, no consequence of the limited space within automobile structure during installation and design, and conveniency for arrangement; the curved reflector has positive focal power and can perfect focusing, not only ensuring good projection effect, but also decreasing the number of lenses with positive focal power in the system, and effectively reduce the volume and weight of the system.

A road surface drawing system includes a road surface drawing lamp that is provided in a vehicle and illuminates a road surface with a beam, and a controller that controls the road surface drawing lamp and draws, with a beam BM, a pattern PTN on the road surface ahead of the vehicle. The controller draws a pattern PTN instructing the vehicle to stop if a signal state of an upcoming traffic signal is a red light.

A lighting device irradiating light to different locations includes a light irradiation unit that generates light; an optical path adjustment unit that adjusts a path of the light radiated from the light irradiation unit to allow a road surface pattern to be formed at a predetermined location on a road surface around a vehicle; and a driving unit that adjusts the optical path adjustment unit to allow the road surface pattern to be formed at different locations on the road surface around the vehicle.

To protect observer's eyes while forming a clear illumination pattern on a desired region to be illuminated. An illumination device includes a light source that emits coherent light, a collimating optical system that enlarges and collimates a beam diameter of the coherent light emitted from the light source, and a diffractive optical element that diffracts the coherent light collimated by the collimating optical system into a predetermined diffusion angle space. The diffractive optical element has a plurality of element diffractive optical portions and has a function to illuminate the region to be illuminated defined at a predetermined position and having predetermined size and shape to form the desired illumination pattern. Each of the plurality of element diffractive optical portions has a function to illuminate at least a part of the region to be illuminated, and diffractive characteristics of the element diffractive optical portions are different from each other.

An illumination device includes a light source unit that emits light, a first optical unit that lets the light enter and changes a divergence angle of the entered light, a second optical unit including an image light formation unit that lets the light with the changed divergence angle enter and emits light including image light having image information, and a drive unit that moves the first optical unit and the second optical unit.

A lighting device of a rear view device of a motor vehicle, includes at least one light source with at least one light emitter for emitting light which can be coupled into and out of a light guide with at least one light funnel in order to pass at least through part of a light transmission unit and illuminate an area adjacent to the motor vehicle, where each light funnel extends upward or downward from its light input end to its light output end, and each light emitter is associated with a light funnel determining an optical axis.

A roof panel assembly for use in a roof of a vehicle comprises at least one roof panel, providing a first interior surface configured to be directed to an interior space of the vehicle and a second interior surface configured to be directed to the interior space of the vehicle. The roof panel assembly further comprises a support beam arranged between the first interior surface and the second interior surface and a projector device arranged on the support beam. The projector device is configured to project a light image on at least one of the first interior surface and the second interior surface.
