Abstract

The invention relates to a turbomachine (H) comprising an air flow generation unit (1) which can be excited to create vibrations and which includes a Chladni resonator (3, 9) having at least one resonantly excitable plate (3). An illumination device (R) includes at least one turbomachine (H) for cooling at least one light source (L). The method, which involves the exciting of a plate (3) of a Chladni resonator (3, 9), is used to produce a cooling air flow (K). The invention can be advantageously used in particular for cooling LED lights and/or luminaires equipped with LED lights.
