LIGHTING ASSEMBLY AND METHOD FOR PROVIDING COOLING OF A LIGHT SOURCE

摘要

The present invention relates to a lighting assembly (100) for providing cooling of a light source (101), the lighting assembly (100) comprising a heat sink (102) comprising a phase change material for dissipating heat generated by the light source (101), means (106) for active cooling of the heat sink (102), and means (105) for activating the active cooling means when the light source is switched off. The lighting assembly according to the present invention minimizes the necessary off period between two on periods when the light source is switched on consecutively multiple times. At the same time, the present invention provides a quiet and vibration free cooling of the light source during the on period of the light source, and subsequently boosts the dissipation of heat received by the heat sink comprised with the phase change material when the light source is switched off. The present invention also relates to a corresponding method for providing cooling of a light source for a lighting assembly.
