Problem:  Design internal heatsink components for a light fixture such that it can operate in high ambient environments while keepng critical internal components within their lifetime temperatures.

Action: 

• Basic iterations used to understand the thermal dissipation patterns

  • Captured using thermocouples and forward looking infrared radiometer (FLIR)

• Models shown below were designed in SolidWorks and prototyped using in-house sheet metal operations

• The fixture was thermally tested to find the optimal material, material thickness, additional heatsinks, lens types, and arrangement of components

• Adjusted heatsink design based off of data found at high ambient temperature thermal tests.

Result: After more iterations, the designs were made to specifications out of house and thermal testing continued
