Illumination device and method of manufacturing the same
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.
ILLUMINATION DEVICE
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.
Multiband Adjustable Lights
A vehicle may have lights such as headlights. The lights may emit visible and infrared light. Infrared light may be used to illuminate objects that are monitored using infrared image sensors or other infrared sensors. Visible light may be used to illuminate objects that are viewed by vehicle occupants and which may be monitored using sensors. Headlights and other lights in the vehicle may be adjustable. An adjustable light may have a light source that contains an infrared light-emitting device such as an infrared light-emitting diode and a visible light-emitting device such as a visible light-emitting diode. A reflector may reflect light from the light source towards a lens. An adjustable light-blocking device may be located between the reflector and the lens. The light-blocking device may allow infrared light to pass unimpeded while adjusting visible light passing to the lens.
Lighting device for vehicle
A lighting device for a vehicle may include: a housing mounted on a vehicle body; one or more light sources mounted in the housing, and configured to emit light; and a screen having 3D surfaces corresponding to the number of the light sources, and configured to generate a 3D lighting by transmitting the light emitted from the light sources.
Illumination Apparatus for a Motor Vehicle Headlight
An illumination device (10) for a motor vehicle headlight, wherein the illumination device (10) comprises: a light source (50) for irradiating a light beam in a first direction of radiation (X1), a first deflection device (100) configured to deflect the light beam in a second direction of radiation (X2), and a second deflection device (200) for deflecting the light beam deflected by the first deflection device (100) in a third direction of radiation (X3) and for producing a light distribution in front of the illumination device (10), wherein
the illumination device comprises at least one expanding optic (300) with a focus (F1), wherein said expanding optic (300) is associated with the at least one light source (50) and is configured to expand the light beam emitted by the light source (50) in the direction of the first direction of radiation (X1), wherein the at least one light source (50) is arranged in the direction of the first direction of radiation (X1) between the at least one expanding optic (300) and the focus (F1) of the expanding optic (300).
PBS-BASED ADB FUNCTION ADJUSTMENT METHOD AND INTELLIGENT VEHICLE LIGHT MODULE THEREFOR
Disclosed are PBS-based ADB function adjustment method and an intelligent vehicle light module therefor. A light source system and a light control element constitute an intelligent illumination light control system. One part of light rays emitted by the intelligent illumination light control system penetrate through a PBS to form an illumination light shape, and the other part of the light rays emitted by the intelligent illumination light control system are reflected by the PBS in a direction opposite to a photosensitive chip integrated circuit. Ambient light enters an imaging lens group in a direction opposite to an illumination light path, and one part of the ambient light is reflected by the PBS to the photosensitive chip integrated circuit to form an information source for dynamic control of the light control system.
