Cooling arrangement for a luminaire |
| 摘要 |
A cooling arrangement comprising a source electrode, a first and a second target electrode arranged at a distance from the source electrode and control circuitry for controlling a voltage being applied between the source electrode and at least one of the first and the second target electrodes. The voltage is controlled such that an airflow resulting from a potential difference between the source electrode and at least one of the first and the second target electrodes is arranged to have alternating directions. By means of the invention it may be possible to provide cooling of a device having similar or better performances than a conventional heat sink and fan system, but with a smaller size and weight as well as being silent. |

1. A cooling arrangement, comprising:
a source electrode for generating air ions; a first and a second target electrode arranged at a distance from the source electrode; and control circuitry for controlling a voltage being applied between the source electrode and at least one of the first and the second target electrodes, wherein the application of the voltage is controlled such that an airflow resulting from a potential difference between the source electrode and at least one of the first and the second target electrodes is arranged to have alternating direction by alternately applying the voltage between the source electrode and the first target electrode and between the source electrode and the second target electrode, respectively. |
