An illumination device for backlighting an image reproduction device containing light valves, the illumination device including a plurality of luminous spots arranged in grid format on a flat thermally conductive carrier. Each luminous spot having a plurality of light emitting diodes electrically insulated from one another, and a submount exhibiting good thermal conductivity and being connected to the carrier.

Illumination device having luminous spots formed by light emitting diodes

An optoelectronic component () having a semiconductor arrangement () which emits and/or receives electromagnetic radiation and which is arranged on a carrier () which is thermally conductively connected to a heat sink (). External electrical connections () are connected to the semiconductor arrangement (), where the external electrical connections () are arranged in electrically insulated fashion on the heat sink () at a distance from the carrier (). This results in an optimized component in terms of the dissipation of heat loss and the radiation of light and also in terms of making electrical contact and the packing density in modules.

Optoelectronic component and a module based thereon

The invention relates to a light source () comprising at least one light module () and one control module () provided with a control electronics system. The invention also relates to an image-generating unit () for a head-up display provided with an inventive light source (). Traditional solutions require too much construction space or cannot be mass-produced in order to obtain sufficient brightness. The aim of the invention is to combine a high degree of brightness, little construction space and mass-producibility, particularly for a head-up-display. According to the invention, the light module () and the control module () respectively comprise their own carrier element ()and are firmly connected to a common carrier (). The light module () is connected to the control module () by means of first electrical lines which are configured in such a way that thermally induced relative movements between the control modules () and light module () are received in a trouble-free manner by modification of the form of the lines.

A straw holder for supporting a drinking straw in the mouth of a bottle is presented. The holder includes a straw support portion dimensioned for placement across the mouth of a bottle. The straw support portion includes an aperture designed to receive a straw therethrough and to vertically support the straw with respect to the support portion. The holder further includes a bottle retaining portion that includes at least one turn extending around the retaining portion. The at least one turn includes a first turn having an end attached to the straw support portion.

Head-up display

The invention relates to a display device, especially in a motor vehicle, comprising a display () which can be illuminated by a light source (), and a light guide () which is arranged between the light source () and the display (). Said light source () comprises a plurality of individual light sources (), the entire light-radiating surface of said light sources being larger than the surface of the display (). In order to increase the light efficiency, the light guide () comprises, on the light source side, individual light guiding sections () which are associated with the individual light sources (), said sections forming a common light guiding section () on the display side.

Display device

A method for driving an electroluminescent lamp to emit light at a brightness set level includes providing a variable bias voltage to the electroluminescent lamp. The variable bias voltage is increased with the duration of the on-time of the electroluminescent lamp. To stabilize the electroluminescent lamp at the brightness set level against aging, a closed loop control of the brightness of the electroluminescent lamp is applied, which is subject to said duration of the on-time the electroluminescent lamp.

Headup display

In an instrument cluster for motor vehicles with a variable-color display, with which at least two different measured variables and/or operating states of the motor vehicle can be represented in analog and/or digital form, when a value of a measured variable is overshot or a certain operating state of the motor vehicle is entered, the color and/or brightness of representation of more than one measured value displayed and/or operating state displayed are changed.

Instrument cluster for motor vehicles with variable-color display

In an indicating instrument, especially in a motor vehicle, having a cover glass ( ) that appears dark and, under incident light, prevents any view of a dial ( ) arranged at a distance behind it, and having at least one light source ( ) arranged behind the dial ( ) to transilluminate said dial ( ) and therefore render the dial ( ) visible through the cover glass ( ). In order to prevent the dial ( ) becoming visible when there is only incident light, the transmission of the dial ( ) is matched to the transmission of the cover glass ( ). To this end, in particular, the dial ( ) is provided with a low transmission.

Indicating device

In a pointer-type instrument ( ) having a pointer with a pointer shaft ( ) that deflects a pointer vane ( ), power is supplied to a light source ( ), which is connected to the pointer for rotation in common, by a flexible, spiral film ( ) provided with conductor tracks ( ). For this purpose, the pointer shaft ( ) has an enlargement ( ), which supports the film ( ) and secures it against sliding off axially. As a result, the film ( ) can be made particularly thin, thereby making it possible to reduce the driving torque required to deflect the pointer shaft ( ).

Pointer instrument

In a pointer instrument, a LED ( ) is arranged in such a way that light can pass from it into a free end face ( ) of a pointer shaft ( ) which is embodied as a light guide. For this purpose, a printed circuit board ( ) on which the LED ( ) is fitted has an opening ( ) which is flush with the end face ( ) of the pointer shaft ( ) and into which the LED ( ) projects, at least partially.

Display instrument, in particular in a motor vehicle

In an operating device having an actuator ( ) with at least two adjustment degrees of freedom, provision is made for said device to have a device ( ) for evaluating the position of the actuator ( ) optically.

In a pointer instrument ( ) having a pointer shaft ( ) that deflects a pointer flag ( ), the pointer flag ( ) can be illuminated by means of a light source ( ). For this purpose, the light source ( ) is formed, for example, as a light-emitting polymer ( ), which is applied between the pointer flag ( ), which is formed at the same time as an electrode, and a further, transparent electrode ( ), and emits light of any desired coloration under appropriate electrical excitation. The pointer flag ( ) can assume any desired shape as the result of using such a light source ( ) that can be shaped. In particular, multiple curvatures can be represented without differences in brightness occurring in this case.
