    Abstract: When light is off, a transparent appearance is obtained, while when the light is on, light is seen through a transparent spot. The present invention includes a light source portion and a reflective portion. The light source portion emits light. The light source portion is disposed at a position shifted with respect to an emitting direction of emitted light from the reflective portion. The reflective portion reflects the light from the light source portion and emits it in a predetermined direction. The reflective portion is constituted by a transparent member with a refractive index at least in a visible light area larger than 1. As a result, in the present invention, the transparent appearance is obtained when the light is off, while the light is seen through the transparent spot when the light is on.

    Abstract: A holographic lighting device for vehicles with a light source for emitting light and with an optical unit containing a hologram element which is set up in such a way that a hologram image is generated in a given field of view. In the hologram element, such hologram information is inserted that by changing a viewing angle from a center position of the viewer, in which the viewer is arranged vertically to a surface of the hologram element, in the direction of a lateral boundary position of the viewer in which a boundary of the field of view is reached, at least in some areas, a distance between the generated hologram image and the hologram image in the center position is increased or is rotated by a vertical and/or horizontal axis, and/or a brightness of the hologram image is reduced.

    Abstract: The disclosure provides a vehicle approach notification device and a picking truck. The vehicle approach notification device includes a first illumination portion provided on a cab capable of elevation; a second and a third illumination portion provided on a vehicle body incapable of elevation; and a control unit that (1) turns on the first illumination portion and off other illumination portions when a travel state of the vehicle body is backward travel and an elevation position is lower than a predetermined threshold value; (2) turns on the second illumination portion and off other illumination portions when the travel state is backward travel and the elevation position is equal to or higher than the threshold value; (3) turns on the third illumination portion and off other illumination portions when the travel state of vehicle is forward travel; and (4) turns off all illumination portions when the travel state is travel stop.
