In this paper, experimental case studies were conducted to investigate the heat dissipation performance by changing the design shape and installation angle of the heat sink in an automotive LED lamp. Two different types of heating source, LED and film heater, were used for the experiment. The standard heat dissipation performance test procedure was conducted under the natural convection condition, and the effect of convection hole and the installation angles in the vertical and horizontal directions were compared. Results showed that convection holes were useful in reducing junction temperature to be lower than that of normal shape as 2.4 ~ 2.8 oC less. The vertical installation angle of horizontal direction showed the best heat dissipation performance. In addition, the heat source type was not a dominant factor of the heat dissipation performance according to changes in the installation slope angle. |
