<p>The invention relates to a lamp having a light source, for example in the form of light emitting diodes (2), a lamp housing (3) and energy conversion means (4) for converting energy of an air flow into electric energy, for example a turbine (10) having an integrated dynamo for charging a battery that is used for the energy supply of the light source (2). The energy conversion means (4) are designed to convert energy of an air flow (6) that is directed upward within the lamp housing (3). A chimney (8) can be provided for guiding the air flow that is directed upward, comprising a chimney wall (22) that is thermally connected to the light emitting diodes (2) and a solar panel, thus increasing the stack effect. The solar panel (20) can also be provided for charging the battery (12).</p> |
