Hello! I am a computational biophysicist currently working on Fluctuating Finite Element Analysis at the University of Leeds, UK.
You can get in touch with me at [email protected]. While you're here, please take a look at my CV and LinkedIn profile!
I was employed as an engineer for 15 months at Sharp Devices Europe, between Summer 2014 and Autumn 2015. My principal responsibilities were: designing tests for LED performance, writing software, web design and development, comptetitor product analysis, and writing manuals. You can read my reference on my LinkedIn profile.
The Physics and Thermal Characterisation of Sharp LEDs
As you probably know, halogen light bulbs are incandescent: they produce light as a side effect of being heated up. Conversely, LEDs are semiconductor devices, and prolonged heat can be very damaging to them. LED devices tend to be cooled in a similar way to computer CPUs – using a thermal interface (like thermal paste) a heatsink, and sometimes a fan as well. However, the effectiveness of these cooling methods can vary wildly, depending on the operational limits of the LED and the type of thermal interface being used. In this article, I’ll discuss the experimental methods I designed to characterise the thermal performance of LEDs using a variety of cooling methods.
