Application52 Fluid-Thermal Analysis of LED Light Bulb

Designing an LED light bulb requires a heat dissipation design that efficiently dissipates the heat inside the bulb to the outside and reduces the heat transfer to the components inside the bulb.

The natural convection inside and around the LED light bulb, and the temperature distribution are solved.
