Problems solved by technology

This mixture makes it difficult to assign adjustment positions to adjustment values ​​and thus makes it more difficult to use adjustment devices
In addition, the time required for the user to recognize the individual adjustment positions is thus longer; this results in a subjectively perceivable loss of comfort and, in disadvantageous cases, affects the concentration of the user, thus posing a safety risk

Embodiment Construction

[0026] figure 1 Shown is a lighting device 1 according to the invention as part of a control device 2 for a heating and air-conditioning system of a motor vehicle, with a control device 3 which is designed here as a rotary regulator 4. In addition, the adjustment device includes a reading surface 5. The position of the pointer 6 changes with the adjustment position of the rotary regulator 4. The lighting device has at least two sections 7, 8 distinguished by different brightness 9, 10 or different colors 11, 12. The sections 7 and 8 are themselves light-emitting surfaces and extend toward the transition area 13 with each other. In other words, the two sections 7, 8 emit light of different colors 11, 12 of different intensities and / or different (visible) wavelengths in each of their possible working or emitting states, and therefore easily visible by the user.

[0027] In the transition area 13 between the sections 7 and 8, the light guide material 14 of the lighting device has ...

Abstract

An illuminating device is provided for an adjusting mechanism adapted to adjust an operating parameter in a vehicle, with a light-transmitting material that extends along the direction of extension and emits light visible to the user in a first and a second section. In order to realize the transition area between the two light-emitting sections concise and such that it can be easily recognized by the user, it is proposed that the light-transmitting material features a light-transmitting transition area with reduced material thickness between the first and the second section referred to the direction of extension.

Description

Technical field [0001] The invention relates to an illuminating device for adjusting equipment for adjusting working parameters in a car. The illuminating device has a light guide material extending in an extension direction, which emits visible light in the first and second sections Light. Background technique [0002] A device of the type mentioned at the beginning is known from the German patent document DE 102 25 016 B4, which describes an operating button radially surrounded by a light conductor in the viewing direction. Multiple light-emitting diodes protruding into the light conductor are used as light sources. The light conductor is visible to observers and users as a circular luminous surface. The light-emitting diodes arranged concentrically with the light conductor along the arc of the ring circuit board are divided into multiple levels according to color and / or brightness. Thus, the light emitting surface emits light of different colors and / or brightness in differe...
