Research on Heat Sink for LED Stage Lighting Lamp

Most of the LED Stage Lighting lamps use LED arrays or LED chips, while gathered chips require faster heat dissipation. If LED temperature gets too high, it will inevitably lead to its optical, electrical and color performance change, and will seriously affect LED working performance and its life. This paper mainly discussed LED Stage Lighting lamp heat dissipation, using the finite element method to analyze the LED temperature field. Then we used ANSYS Workbench to simulate the field and optimize its dissipating performance, and finally designed a LED radiator. Results showed that after the optimization, it had solved the heat accumulation problem of LED lamp, reduced the center temperature of LED effectively, keeping LED work in a proper temperature range.
