Disclosed is a light appliance and a cooling arrangement, comprising a light appliance and a substantially sealed enclosure for the light appliance that gives off unwanted heat into surrounding air within the enclosure during operation. The enclosure has an external wall at least part of which is thermally conductive. A medium, cooler than the external wall of the enclosure, contacts the external wall. An air circulating device is provided for circulating air, heated by the electrical appliance or by the air circulating device, to the thermally conductive portion of the external wall for removing heat from the air by thermally dissipating the heat into the cooler medium through said thermally conductive portion. |
