Abstract
It is presented a heat managing device for a light source () which combines heat managing by means of a heat sink, heat pipes and forced convection, thereby achieving efficient cooling of high power lighting applications. The heat managing device comprises a heat spreading element () having an upper side arranged for thermally connecting to at least one light source (). The light emitted from the light source is controlled by secondary optics (). The heat managing device comprises a heat sink which is thermally connected to the heat spreader, and to a first set of heat pipes which is thermally connected to the heat spreader. At least a portion of the heat sink is arranged to encompass the secondary optics. The heat pipes are embedded in the heat sink. Further, a fan for providing forced air convection at the heat sink is comprised in the device. A corresponding lighting device is also presented.
