Fin-type heat dissipation structure of light emitting diode lamp

The heat dissipating area of light emitting diode (LED) is calculated and the model of LED heat dissipation with platy cooling fins is established and simulated by ANSYS. When the ratio of fin spacing and fin thickness is 3∶2 or the ratio of fin thickness and base thickness is 1∶1, the heat dissipating performance of LED is the best, on condition that other parameters are fixed. With the increase in the number of fins and the height of fins, the heat dissipation performance improves.
