Abstract

A ventilation nozzle arrangement for a cockpit of a vehicle includes a ventilation nozzle for ventilating the vehicle by an airflow and plurality of fins between which the airflow can escape and/or escapes in a ventilation direction. The fins consist of a light-permeable material.

First claim

What is claimed is:

1. A ventilation nozzle arrangement for a cockpit of a vehicle comprising:
a ventilation nozzle including a central hub and an outer ring for ventilating the vehicle by an airflow;
twelve equiangularly spaced fins radially extending from the central hub and terminating at the outer ring between which the airflow escapes in a ventilation direction, each of the twelve fins having a light-permeable material defining a visible edge when viewed in a direction opposite the ventilation direction, wherein the twelve fins correspond to a clock face;
a first light-emitting diode array having twelve first light-emitting diodes arranged relative to one another at an angle of 30 degrees, wherein one of the twelve first light-emitting diodes is associated with one of the twelve fins;
a second light-emitting diode array having twelve second light-emitting diodes arranged relative to one another at an angle of 30 degrees, one of the twelve second light-emitting diodes is associated with one of the twelve fins; and
a control device configured to operate the first and second light-emitting diode arrays such that one of the first light-emitting diodes in the first light-emitting diode array selectively illuminates one visible edge on the twelve fins and of the second light-emitting diodes of the second light-emitting diode array selectively illuminates one of the visible edges on the twelve fins for providing a time display on the ventilation nozzle.

2. A ventilation nozzle arrangement for a cockpit of a vehicle comprising:
a ventilation nozzle for ventilating the vehicle by an airflow;
a plurality of light permeable fins arranged in the ventilation nozzle between which an airflow escapes in a ventilation direction;
an illuminating device for illuminating at least one of the plurality of fins comprising a first light-emitting diode array having a plurality of first light-emitting diodes and a second light-emitting diode array having a plurality of second light-emitting diodes; and
a controller configured to selectively illuminate at least one of the first light-emitting diodes in the first light-emitting diode array and at least one of the second light-emitting diodes of the second light-emitting diode array, wherein the control device is configured to selectively illuminate exactly one of the first light-emitting diodes of the first light-emitting diode array and exactly one of the second light-emitting diodes of the second light-emitting diode array for illuminating at least one of the fins to provide a time display.

3. A ventilation nozzle arrangement for a cockpit of a vehicle comprising:
a ventilation nozzle having an outer ring and a plurality of fins radially extending across the outer ring between which an airflow escapes in a ventilation direction, each of the plurality of fins having a light-permeable material defining a visible edge when viewed in a direction opposite the ventilation direction;
a light emitting ring operably coupled to the light-permeable material to illuminate the visible edges of the fins; and
a controller configured to operate the light emitting ring for illuminating the visible edges of the fins.

4. The ventilation nozzle arrangement according to claim 3 , wherein the light-permeable material comprises a light guide operably coupled to the light emitting ring for selectively illuminating the visible edges of the fins.

5. The ventilation nozzle arrangement according to claim 3 , wherein the ventilation nozzle further comprises a central hub, wherein the plurality of fins are equiangularly spaced and radially extend from the central hub and terminate at the outer ring.

6. The ventilation nozzle arrangement according to claim 5 , wherein the controller is further configured to operate the light emitting ring for selectively illuminating the visible edges of the fins such that less than all of the plurality of visible edges are illuminated to provide a dial display.

7. The ventilation nozzle arrangement according to claim 5 , wherein the light emitting ring comprises a first light emitting array configured to selectively illuminate a first section of the light-permeable material and a second light emitting array configured to selectively illuminate a second section of light-permeable material, wherein the first section is radially spaced with respect to the second section.

8. The ventilation nozzle arrangement according to claim 3 , wherein the plurality of fins consist of twelve fins.

9. The ventilation nozzle arrangement according to claim 8 , wherein the twelve fins correspond to a clock face having twelve hour units and/or twelve five-minute units for simulating a clock face.

10. The ventilation nozzle arrangement according to claim 3 , wherein the light emitting ring comprises a first light-emitting diode array having a plurality of first light-emitting diodes and a second light-emitting diode array having a plurality of second light-emitting diodes.

11. The ventilation nozzle arrangement according to claim 10 , wherein the first light-emitting diode array has a first radius and the second light-emitting diode array has a second radius that is smaller than the first radius.

12. The ventilation nozzle arrangement according to claim 11 , wherein the first light-emitting diode array surrounds the plurality of fins forming a circular ring-shaped frame therefor and the second light-emitting diode array surrounds the common center.

13. The ventilation nozzle arrangement according to claim 8 , wherein the light emitting ring comprises a first light-emitting diode array consisting of twelve first light-emitting diodes arranged relative to one another around the common center at an angle of 30 degrees, wherein one first light-emitting diodes is associated with one of the twelve fins, and a second light-emitting diode array consisting of twelve second light-emitting diodes arranged relative to one another around the common center at an angle of 30 degrees, wherein one second light-emitting diodes is associated with one of the twelve fins.

14. The ventilation nozzle arrangement according to claim 13 , wherein each of the twelve first light-emitting diodes of the first light-emitting diode array is paired with one of the twelve second light-emitting diodes of the second light-emitting diode array to for a diode pair associated with one of the twelve fins.

15. The ventilation nozzle arrangement according to claim 10 , wherein the control device is configured to selectively illuminate exactly one of the first light-emitting diodes of the first light-emitting diode array and exactly one of the second light-emitting diodes of the second light-emitting diode array for selectively illuminating visual edges of the fins to provide a time display.
