    Abstract: The invention relates to a method for producing an optical device (1) comprising at least one light source (16), at least one light guide (10) having an entry surface (11) facing the light source (16), and having an exit surface (12) formed at an end of the light guide (10) lying opposite the entry surface (11), in order to allow light entering into the light guide (10) to exit same, and a projection optics (20) which is designed to project the light exiting the exit surface (12) onto a projection plane (26) provided at a distance from and at an angle of inclination (γ) relative to a main direction of emission (Z) of the optical device (1). The method comprises the following steps: specifying a target distribution of the illuminance in the image (15) projected into the projection plane (26) by the projection optics (20); determining a non-homogenous distribution of the illuminance (Ev) of the light across the exit surface (12) from the distribution to be specified of the illuminance in the image (15) projected into the projection plane (26); determining a three-dimensional shape of the at least one light guide (10) with which the non-homogenous distribution of the illuminance (Ev) of the light across the exit surface (12) is generated when light is emitted by the at least one light source (16); and producing the light guide (10) with the three-dimensional shape and assembling the components of the optical device (1).

    Abstract: A road surface drawing lamp is configured to be mounted on a vehicle. The road surface drawing lamp is configured to draw a sequential light pattern in which an irradiation region changes in a sequential manner in a drawing region set in a surrounding region of the vehicle. The road surface drawing lamp is configured to first form, as the sequential light pattern, a first light pattern which is drawn at least in a part including a tip portion of the drawing region.

    Abstract: A light shielding plate for shielding part of light from a light emitting element to a projection lens is arranged between the light emitting element and the projection lens, and an opening penetrating the light shielding plate is formed in a required region of the light shielding plate. With this configuration, the drawing light distribution pattern can be formed as a light distribution pattern corresponding to the opening shape of the opening. In this configuration, the inner peripheral surface of the opening has such a surface shape that light emitted from the light emitting center of the light emitting element does not enter the projection lens. Thus, even if the plate thickness of the light shielding plate is increased, occurrence of color unevenness in an outline portion of the drawing light distribution pattern due to light reflection on the inner peripheral surface of the opening is effectively reduced.

    Abstract: A lighting system includes a projection surface and a lighting device that projects a projection pattern on the projection surface and includes a light source emitting coherent light and a diffractive optical element diffracting the coherent light to form the projection pattern and including fundamental pieces of diffractive optical element two-dimensionally arranged in a direction parallel to the projection surface. A fundamental period of spatial resolution r (on the projection surface and determined from a specified spatial resolution of the projection pattern at an intersection position of a perpendicular line drawn from a center of certain one of the fundamental pieces of diffractive optical element with respect to the projection surface), an angle θ (a half of an angle projecting the fundamental piece of diffractive optical element at the position), and a wavelength λ of light in the projection pattern projected at the position) satisfy sin θ>λ/(6r).

    Abstract: Light module system, comprising a first light module and a second light module, wherein the first light module can be controlled in dependence on the second light module, wherein the first light module is configured as a non-high-resolution light module, and is set up to generate a light distribution of a first type (1, 10) in a region in front of the light module system, wherein the light distribution of the first type (1, 10) can be dimmed, the second light module is configured as a high-resolution light module, wherein a minimum brightness is associated with a sector (4) of the light distribution of the first type, and the second light module is set up to generate at least one ground-projection light distribution (3) in an operating mode, wherein the at least one ground-projection light distribution (3) is a visual presentation of information, and thereby to cause the first light module to, at least partially, dim the light distribution of the first type, and to illuminate the sector (4) of the light distribution of the first type.

    Abstract: A projection system for a vehicle, in particular for an ambient lighting device for generating a plurality of light cones for illuminating the ground in the surroundings of the vehicle, includes at least one light source and a microlens array. The microlens array includes an optical axis, a first portion with at least one first channel and a second portion with at least one second channel. The projection system includes an optical device that is provided downstream of the microlens array and is arranged at least in the area of the first portion, with the distance between the microlens array and the optical device being less than 20 mm. Light emitted by the light source, which falls through the at least one first channel of the first portion, is deflected by the optical device by a first angle with respect to the optical axis and forms a first light cone, and light emitted by the light source, which falls through the at least one second channel of the second portion, is deflected by a second angle with respect to the optical axis, which differs from the first angle, and forms a second light cone.
