Abstract

The present invention is directed to a cooling system (1) for electronic components (4). The cooling system (1) comprises means (7) for producing cyclic air pressure fluctuations, wherein the electronic components (4) are distanced from the pressure producing means (7). In the vicinity of the electronic components (4) are situated means (5), preferably restrictions like holes, which are affected by the cyclic air pressure fluctuations, and which produce cyclic air jets (6). The air jets (6) affect the surface of the electronic component (4), and since the air jets (6) originate directly in the vicinity of the electronic components (4), an efficient heat transfer is affected. Preferably, the pressure producing means (7) actuate a pressure Pc inside a chamber (2), and turbulent air jets (6) are produced through holes (5) of a substrate (3), onto which electronic components (4) are mounted.

Description

technical field

[0001] The present invention relates to cooling systems and methods for electronic components, and more particularly to cooling systems for electronic components integrated into LED lamps, especially improved LED lamps. The cooling system according to the invention works by generating cyclic air pressure fluctuations which produce cyclic air jets which affect and cool the surfaces of the electronic components. Background technique

[0002] LED lights (especially modified LED lights) that include one or more light emitting diodes (LEDs) require electronic components to operate. In higher power LED lamps, the electronic components generate a lot of heat due to conversion losses. Especially in retrofit LED lamps, which operate with high intensity LEDs and are enclosed by bulbs, the heat generated is very high and can negatively affect lamp performance and lifetime. Therefore, active or forced cooling of the electronic components within such lamps is required. ...
