ALTERABLE HEAT SINK CORRESPONDING TO THE AMOUNT OF HEAT RADIATION

摘要

PURPOSE: According to the heat sink can vary according to the radiation amount is the whole radiation amount of the heating element, the unnecessary mould drawing and manufacturing cost are reduced by laminating the heat radiation fin of the heat sink for the heat dissipation and heat sink. CONSTITUTION: The variable form heat sink comprises the first heat sink(300a) and the second heat sink(300b). The first heat sink comprises the heat sink body(310a) facing the heating surface of the LED illumination heating element(200b) and an plurality of heat radiation fins(320) formed with the heat sink body. The heat sink body having a plurality of heat radiation fins forms one unit heat sink.
