Abstract
A micro-lens array projection device has at least one light source, a field lens array, a projection lens array, and a pattern template arranged in a light beam path coming from the light source between the field lens array and the projection lens array for generating a light pattern from the light emitted by the light source. The pattern template is formed by a microslide array having at least two microslides. At least one microslide can be moved by at least one actuator in a plane located perpendicular to an optical axis between the field lens array and the projection lens array.
Claims8
A micro-lens array projection device, comprising:
- at least one light source;
- a field lens array;
- a projection lens array;
- and
- a pattern template arranged between the field lens array and the projection lens array in a light beam path coming from the at least one light source,
- wherein the pattern template is configured to generate a light pattern from light emitted by the at least one light source, and
- wherein the pattern template is a microslide array comprising at least two microslides, wherein at least one microslide of the at least two microslides is movable by at least one actuator in a plane located perpendicular to an optical axis between the field lens array and the projection lens array.
A vehicle, comprising:
- a lighting device comprising at least one micro-lens array projection device, which comprises
- at least one light source;
- a field lens array;
- a projection lens array;
- and
- a pattern template arranged between the field lens array and the projection lens array in a light beam path coming from the at least one light source,
- wherein the pattern template is configured to generate a light pattern from light emitted by the at least one light source, and
- wherein the pattern template is a microslide array comprising at least two microslides, wherein at least one microslide of the at least two microslides is movable by at least one actuator in a plane located perpendicular to an optical axis between the field lens array and the projection lens array.
A method comprising:
- providing a micro-lens array projection device, comprising at least one light source, a field lens array, a projection lens array, and a pattern template arranged between the field lens array and the projection lens array in a light beam path coming from the at least one light source, wherein the pattern template is configured to generate a light pattern from light emitted by the at least one light source, and wherein the pattern template is a microslide array comprising at least two microslides, wherein at least one microslide of the at least two microslides is movable by at least one actuator in a plane located perpendicular to an optical axis between the field lens array and the projection lens array;
- moving the at least one microslide in the plane located perpendicular to the optical axis between the field lens array and the projection lens array;
- and
- generating, by the pattern template from the light emitted by the at least one light source, the light pattern.
