  • Patent number: 10371465
    Abstract: A heat exchanger may include input-side and output-side tube plates and tubes supported therein, forming a first flow duct for a first medium. A housing may surround the tube plates and the tubes, forming a second flow duct for a second medium running between the tubes in the housing. The heat exchanger may further include at least one turbulence-generating insert arranged in the second flow duct between the tubes, the insert having ducts with permeable side walls for the second medium, and at least one dividing wall duct having closed side walls and being spaced apart at least at one longitudinal end from the housing. The at least one dividing wall duct may be designed to be open at both longitudinal ends, may be produced by a compression process, and may have a rising first flank and a second flank engaging below the second flank.

  • Publication number: 20150222228
    Abstract: The method for characterizing a photovoltaic element (4) comprises a phase of studying (E1) a behaviour of the photovoltaic element (4) in response to the application of a light beam from a light source (2), for example a matrix of light-emitting diodes, at a study emitting power. Said study phase (E1) comprises a step of measuring (E1-1) at least one electrical parameter (I, V) representative of the operation of the photovoltaic element (4). Furthermore, the method comprises an initialisation phase (E2), performed before the study phase (E1), comprising a step of adjustment (E2-1) of an operating temperature of the light source (2) as a function of the study emitting power.

  • Patent number: 7642908
    Abstract: A light system for a vehicle includes a light casing that is fixedly secured to the motor vehicle. The light casing includes brake, fog and spacer sections with the spacer section separating the brake section from the fog section. A controller is fixedly secured to the light casing for receiving electrical power and control signals from the vehicle. A brake light source is disposed within the brake section of the light casing and is electrically connected to the controller to receive the control signals and to selectively emit light based on the signals. The light system also includes a fog light source disposed within the fog section of the light casing. The fog light source is electrically connected to the controller to selectively emit light based on the control signals. The spacer section allows one that is following the vehicle to distinguish between the brake and for light sources.

  • Patent number: 7628516
    Abstract: The invention relates to a headlamp adjusting device with lamp units that can be adjusted in groups. To this end, each lamp unit is mounted individually directly or indirectly in the headlamp housing by means of one respective joint; and it is swivelably mounted in a first feed mechanism. The headlamp adjusting device comprises a second feed mechanism. The second feed mechanism guides the first feed mechanism. The orientation of the feed motion of the first feed mechanism and the orientation of the feed motion of the second feed mechanism enclose an angle, which is not equal to an integral multiple of Pi. With the present invention a space-saving headlamp adjusting device for adjusting the lamp units in two directions of adjustment is developed.

  • Publication number: 20080225542
    Abstract: Lights, for example, in the form of rear lights, have luminous fields (11, 12, 15, 16, 17, 22) in the form of the flasher, the brake light, the tail light and the back-up light. In order to guarantee a homogeneous illumination that is as uniform as possible, the light has reflectors, of which a first reflector reflects the light, coming from a light source, to a luminous field (11, 12, 15, 16, 17, 22), respectively a pane (10). The side of this reflector that faces away from the pane (10) has the additional reflector, which reflects the light of an additional light source past the first reflector to the pane (10). The additional light enables a homogeneous illumination without the need for a lot of technical complexity. The light is intended, in particular, for motor vehicles.

  • Publication number: 20080180970
    Abstract: The light has a housing and a light disc, behind which a lighting unit is provided. The lighting unit is divided into at least two separate light-permeable and distanced light windows, having the same or different lighting functions. A partially light impermeable area is provided between them. In order to embody the light such that its divided light windows are perceived as a continuous lighting area, embodied in a simple fashion and produced cost-effectively, at least one additional light impermeable area is provided in the light impermeable area. Thereby, in spite of the divided light window, a continuous light window is discernible for the observer, as required by the legislature, when both light windows fulfill the same lighting function. The light is suitable as a tail light of motor vehicles.

  • Publication number: 20080019136
    Abstract: The invention relates to a light unit with a light-emitting diode comprising at least one non-glowing light source and with a light distribution body optically downstream to the light-emitting chip source, whereby the frontal area of the light distribution body facing away from the non-glowing light source has a hollow and whereby each periphery of the hollow comprises a total reflection surface for the light emitted from the non-glowing light source. For this purpose, the light distribution body is part of the light-emitting diode. The section of the light distribution body adjacent to the non-glowing light source has an elliptical section as an envelope curve in at least one cutting plane, which encompasses the optic axis. A compact light unit with a high degree of optical efficiency is developed with this invention.

  • Patent number: 6227675
    Abstract: An interior rearview mirror for vehicles has a housing having an interior. A mirror support has a first end and a second end, wherein the housing is connected to the first end of the mirror support and wherein the first end projects into the interior of the housing. A mirror pane is mounted in an opening of the housing. A switching member is mounted in the interior of the housing and is pivotable on the first end of the mirror support. An adjusting lever is mounted in the housing and projects from the housing. At least one spring is configured to act on the adjusting lever. The adjusting lever is movable against a force of the at least one spring and acts on the switching member for pivoting the mirror pane from a normal viewing position into a non-glare position. The switching member receives the force of the at least one spring exerted onto the adjusting lever and thus prevents deformation of the housing.
