VESA mount LED light bar

thingiverse

I get terrible seasonal affective disorder (SAD) every fall. This year, I vowed, I would get a sun lamp! But, hey, why not *make* a sun lamp??? Because I need every inch of desk space to nurture my piles of useless junk, I decided I wanted something I could attach to my monitor. This, I reasoned, would put those delicious photons right onto my brain windows. A couple hours of tinkering in CAD later, this is the result: a 3-foot light bar that hovers above my monitor. It turns out the big wide diffuse light also does a good job making me look less horrific in my all-too-frequent Zoom meetings! I chose some LEDs that allow me to adjust the color temperature, too, for evening use. (Warmer light [may also be effective](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5292307/) for treating SAD!) **Update: ** My partner decided she wanted one too, so I've made an updated diffusor model as well as an updated mount. The 'tape mount' can be mounted to the back of a non-VESA monitor with double-sided tape or 3M command adhesive strips, or used as a foot directly on a desk. The new diffuser design now interlocks, and you need to print one center version and two side versions. Here's my total bill of materials for this build: Clear PLA for diffuser (450g; ~$13; [Atomic Natural PLA](https://atomicfilament.com/collections/opaque-pla-filaments-1/products/natural-pla-filament) looks *way better* than other clear PLA I've tried. PLA is superior to PETG for this as it's less transparent and more diffusive.) Black PLA for bracket (130g; [PrintedSolid Jessie Black](https://www.printedsolid.com/products/jessie-pla-1-75mm-x-1kg-black)) 36"x1" aluminum [extruded heat sink](https://www.heatsinkusa.com/1-000-wide-extruded-aluminum-heatsink/) (~$10) [Adjustable white LED strip](https://www.amazon.com/gp/product/B087LV4MNX/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1) ($24) 12 x 8mm M3 button-head cap screws 4 x 20mm M3 button-head cap screws 2 x 50mm M3 socket-head screws 4 x M3 hex nuts 2 x M3 nylock nuts
