A three-dimensional hologram image producing lamp for a vehicle comprises a light source, a hologram plate displaying a three-dimensional hologram image, a curved slope mirror having a reflecting surface shaped as a parabolic curved surface, facing the light source, and reflecting light, radiated from the light source, toward the hologram plate, and a housing disposed on a lamp receptacle of a vehicle body and having the hologram plate, the light source, and the curved slope mirror mounted thereon.

A mirror and information image display assembly (300) for a vehicle, a holographic information image display system (300, 106, 104), a vehicle (100) comprising such an assembly, and a method of providing image information to an occupant of a vehicle are disclosed. The assembly has a reflective layer (302) and an image display means (304, 306), for displaying image information to an occupant of the vehicle. The image display means comprises a hologram (304), and a lighting means comprising a light source (306) for illuminating the hologram.

Disclosed herein are a method and apparatus for displaying a binocular hologram image. The method includes generating a light beam of an incident wave field having coherence, expanding the generated light beam to the size of the active area of a display, converging the expanded light beam on the respective positions of the eyes of a user, generating digital hologram content, and displaying a hologram image based on the converged light beam and on the digital hologram content.

A lighting device for vehicles having a housing in which is arranged a hologram light fixture that has a light source unit and has an optical unit with a hologram element for generating a predetermined lighting function. An auxiliary element is associated with the light source unit, by means of which light that is emitted by the light source unit can be deflected in the direction of the hologram element. In this design, the light source unit and/or the auxiliary element is arranged in the region of a side of the hologram element or in the region of a lateral extension of an edge of the hologram element extending in the direction of a central axis of the hologram element.

There is herein defined optics (e.g. an array of optics) forming an optical beam to either produce a collimated or diverging/converging beam emerging from a virtual source point to illuminate a hologram. There is also described an optical beam illuminating a reflection hologram from the front and a further configuration where an optical beam combined with a holographic optical element (HOE) minor enables rear illumination of a reflection hologram.

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.

A near-to-eye display device includes a spatial light modulator and a microdisplay. The spatial light modulator provides a high-resolution focused image for central vision. The microdisplay provides a low-resolution defocused image for peripheral vision. The display has a large field of view.

A toy includes a plush body integrated with a fan blade LED assembly. The fan blade LED assembly includes one or more fan blades, a motor to drive the blades, an array of programmable LED lights, and a controller configured to control the operation of the motor and LED lights. By controlling these components, the toy can generate images through specific sequences of lighting while the fan blades rotate. The fan blade assembly is encased within a translucent shell embedded in the plush body, enhancing the visual effects of the images created.

Embodiments of invention are directed to a lighting device for use in accent lighting applications. In one embodiment, the lighting device includes a coherent light source, such as a laser, and a diffractive optical element. The diffractive optical element may be, for example, a holographic optical element. The lighting device may be adapted to retrofit into a pre-existing light fixture. In one application, the lighting device may project a static or movable star field and/or static or movable clouds.
