Custom LED array molded in clear epoxy. To do this, he took a two-pronged approach. One was to replace the single large UV LED with a 4×7 array of emitters plus heat sink and fans.

Just the other day, I reported on this cool project that uses the Raspberry Pi Pico 2's microprocessor to create a business card with an LED array to display liquid physics, and it was really cool.

Ka-ching, the price of our hypothetical tube light just jumped up. The challenge for an LED-based T8 LED replacement light is to cost-effectively replace today’s $2 fluorescent light while maintaining ...

The ability to build micro- and nano-optical devices in large arrays is a challenge being addressed by the University of Strathclyde and MIT.
