A HEAT DISSIPATION STRUCTURE OF A LIGHTING ENGINE, A MANUFACTURING METHOD THEREOF AND A LIGHTING SYSTEM COMPRISING THE STRUCTURE

摘要

The present invention relates to a heat dissipation structure for a lighting engine, comprising: a primary heat sink (2), and an extended heat sink (3), wherein the primary heat sink (2) has a first contact surface (5), and the extended heat sink (3) has a second contact surface (6) provided opposite to the first contact surface (5), the first contact surface (5) and the second contact surface (6) directly contacted each other with no additional layer therebetween. The present invention further relates to a manufacturing method of corresponding heat dissipation structure. The present invention further relates to a lighting system comprising the heat dissipation structure. The heat dissipation structure and lighting system according to the present invention minimize the thermal resistance between the primary heat sink and the extended heat sink and have the advantages of low thermal resistance and simple structure.
