A head lamp module for a motor vehicle is provided, and includes one single printed circuit board, a first group of light sources, a second group of light sources, a lens and an optical device. The first group of light sources and the second group of light sources are both arranged on the printed circuit board. The first group of light sources and the second group of light sources emit light to the optical device. The optical device is adapted to guide the emitted light in a direction towards the lens. The light leaves the head lamp module through the lens.

Provided is a lens assembly applied to a head lamp, and the lens assembly may fix each of a plurality of lenses in an appropriate position to maintain an appropriate distance between the light source and the lens, thereby acquiring a resolution required by a high-resolution adaptive driving beam (ADB) lamp.

A motor vehicle headlight includes a light module, having a light source, a primary optics that collects light and micro projectors, of which each one comprises one respective input lens, one respective output lens and an aperture that is arranged between the input lens and the output lens. The input lens, the aperture and the output lens feature one width and one height. The primary optics, the input lens, the aperture and the output lens of one respective micro projector are arranged in such a way, that the light from the light source that emits from the primary optics illuminates the input lens, and the light of the light source that emits from the input lens illuminates the output lens. The headlight includes micro projectors, whose widths (b) are different and whose heights (h) are different.

An illumination device includes a light source; a light condensing element for concentrating light from the light source onto a light concentration position; a plate for receiving light from the light condensing element and transmitting such light; a phosphor element for receiving light from the light source at the light concentration position; and a lens for projecting light from the plate. The plate is configured to rotate about an axis perpendicular to an optical axis of the lens to shift the light concentration position, which is between the plate and the lens, in a direction perpendicular to the optical axis of the lens.

A lighting device to be mounted on a vehicle has a light source, a projection lens having an optical axis, and disposed so as to allow at least some of light emitted from the light source to pass therethrough, a holder that holds the projection lens, a pivot shaft provided at one of the projection lens and the holder and extending in a direction intersecting with the optical axis of the projection lens, a bearing provided at the other of the projection lens and the holder and that holds the pivot shaft, an aiming mechanism configured to pivot the projection lens relative to the holder about the pivot shaft, and a reflector configured to reflect the light emitted from the light source in a predetermined direction. The reflector is provided in the holder. The position of the holder to the light source is fixed.

A laser unit (11) for a vehicle headlight has a laser diode (12) that is associated with adjustable collimating optics (13) for the laser light emitted by the laser diode. The collimating optics (13), which comprise at least one optical component, e.g., a lens (14), are arranged at a distance, in a longitudinal direction (x), from the laser diode (12), this distance being adjustable by an adjusting device (20). The adjusting device comprises a carrier (24), which is adjustable in the longitudinal direction relative to the laser diode (12) with the help of longitudinal actuation means (21), and in which the optical component (14) is mounted so that it can pivot transverse to the longitudinal direction (x) in a holder (23).

The purpose of the present invention is to provide a vehicular lamp which creates light directed upward using a reflector that allows the light incident below the lower end of the lens to exit upward through a lens and which minimizes the uneven light distribution of the created light distribution pattern. The vehicular lamp according to the present invention includes: a semiconductor light source unit (20) including a light-emitting chip (21); a horizontally long lens (30) disposed in front of the light source unit (20); and a reflector (40) positioned between the lens (30) and light source unit (40) and disposed below the light-emitting chip (21) along a vertical direction. The reflector (40) includes a reflection surface (41) for creating a plurality of virtual focal points intersecting a vertical axis passing through the light emitting center O of the light-emitting chip (21). The distribution of light from the reflection surface (41) is controlled so that light is emitted from a light emitting surface (32) vertically below the optical axis Z of the lens (30). The lens (30) is formed such that, when a point light source is assumed on the optical axis Z, first direct light LM on the optical axis Z emitted from the point light source is distributed upward from the light emitting surface (32).

A headlight module includes a light source, a light guide element, and a projection optical element. The light source emits light. The light guide element has a reflecting surface for reflecting light emitted from the light source and an emitting surface for emitting light reflected by the reflecting surface. The projection optical element projects light emitted from the emitting surface. In a direction of an optical axis of the projection optical element, an end portion on the emitting surface side of the reflecting surface includes a point located at a focal position of the projection optical element.

A light emission device includes a light source that emits an excitation light beam, a light deflector, a wavelength converter that receives and converts the excitation light beam deflected by the light deflector to wavelength-converted light, and a light concentration section that focuses the excitation light beam on the wavelength converter. The light concentration section includes a first optical system disposed between the light source and the light deflector, and a second optical system disposed between the light deflector and the wavelength converter. In the second optical system, a focal length of an Ay-axis is shorter than a focal length of an Ax-axis, where the Ax-axis is defined as an axis that has a lowest beam parameter product of the excitation light beam, and the Ay-axis is defined as an axis orthogonal to the Ax-axis in a cross section perpendicular to a propagation direction of the excitation light beam.

A dual light path forming type projection optical system may include a reflector allowing light generated from a light source to be formed into a lower reflecting light reflected to an upward path directing upward and an upper reflecting light reflected to a downward path directing downward, a prism lens allowing the upper reflecting light to be emitted as a prism low beam in which the downward path is changed into the upward path and allowing the prism low beam to be changed into a prism high beam by changing an incident angle of the upper reflecting light, and an aspheric lens for generating a low beam by allowing the prism low beam to be added to the lower reflecting light and generating a high beam by allowing the prism high beam to be added to the lower reflecting light.
