摘要:
The invention relates to a light module (1) for a lighting device for a motor vehicle. The lighting module (1) comprises a light source (3) for emission of electromagnetic radiation, preferably in the form of light which is visible for the human eye, and a reflector (2) for focusing the emitted radiation. At its apex, in the area of its optical axis (8), the reflector (2) has an opening (7) for holding a light-emitting part (5) of the light source (3). A reflector neck (9) is formed on the reflector (2), surrounding at least a part of the holding opening (7), to which reflector neck (9) another part (4, 6) of the light source (3) is attached. In order to reduce the installation space required for lighting devices in a motor vehicle, it is proposed that the reflector (2) has a slot (17), which extends into the holding opening (7), below the holding opening (7), the width of which slot (17) transversely with respect to the optical axis (8) of the reflector (2) is greater than the width of the light-emitting part (5) of the light source (3). The lamp (3) can therefore be replaced more easily, and in less space.

An actuator (1) has two parts in the iron circuit and has a simple construction. A short-circuit element (3) has an offset (90), which depending on the position of an armature (9) varies the course (60) of magnetic flux in such a way that over the entire stroke, a constant, high magnetic force is achieved, and thus a shallow course of magnetic force in stroke is attained.
摘要:
A projection module for an automobile headlamp includes at least one semiconductor emission source which emits electromagnetic radiation, a reflector reflecting the emitted irradiation, a baffle arrangement shading at least a portion of the reflected irradiation, and a projection lens for projecting the reflected irradiation. The irradiation passes by the baffle arrangement to create a desired emission distribution from the projection module in front of the automobile. At least one emission source is mounted on, or near, the rear side of the baffle arrangement, and a main irradiation direction of the minimum of one emission source is directed into the semi-open space opposite the irradiation-output direction from the projection module.

An actuator unit including a step-up which varies over an adjustment path, between a control motor and a wheel connected to the throttle body in a manner fixed against relative rotation offers the advantage that in certain positions of the throttle body, the required increased torque can also be brought to bear by a relatively low-torque control motor. The actuator unit is intended in particular for internal combustion engines for motor vehicles.

A motor vehicle headlamp (10) including a multi-function projection module (14), which is designed to convert light from a first light source (16) into a first light distribution (34) by means of a first primary lens system (18) in a first beam path bounded by an aperture edge (26), and to focus light from a second light source (20) into a beam waist (44) and convert the light into a second light distribution by means of a second primary lens system (22) in a second beam path. The second light distribution has a predetermined central point (56). The projection module includes a mirror (30), which is arranged in the second beam path between the beam waist (44) and the projection lens (28) in such a way that the mirror produces a virtual mirror image of the beam waist (44) at the focal point of the projection lens.

摘要:
The invention relates to a projection module for a headlight. The module generates light distributions with light sources switchable independently. In order to generate a first distribution, light from a first group is coupled into an optical element in the beam path. The optical element has a reflecting underside having a contour corresponding to the bright-dark boundary. The light coupled out from the optical element is projected by a lens for generating the first distribution. A further light group is additionally activated in order to generate a second distribution. The light emitted by this group illuminates a region of the light distribution above the bright-dark boundary. Part of the light from this group is coupled into the optical element, mixes there with the light from the first group and is then coupled out together to generate an unsharp bright-dark boundary.
