Display Light Fixture

My wife oversees the Learning Center at an elementary school, managing both the library and computer lab. This year's theme is "Learning is Our Super Power," which means every aspect of the school has been transformed into a Super Hero wonderland, complete with decorations surrounding these iconic figures. One notable project my wife took on was creating a 'Kryptonite' display. We envisioned showcasing it in a glass case made from plexiglass, featuring steel angle iron and diamond plate accents. To achieve this, I built the base using wood and welded the angle iron into place. Next, I designed a light fixture to illuminate the kryptonite from underneath, utilizing an LED Halogen replacement light. Upon testing my initial design, we found that even though it was an LED bulb and not a traditional halogen one, it still managed to reach temperatures of approximately 200 degrees Fahrenheit after about an hour. This excessive heat began melting her carefully crafted 'Kryptonite' display. I promptly redesigned the light fixture, incorporating two 30mm cooling fans into the design - one fan pulls air in while the other pushes it out. My goal was to create a channel where the air could circulate across the top of the light via the push/pull fans and then enclose it with plexiglass. I also made space at the bottom for tucking wires. The revised light fixture, showcased here, functions flawlessly without exceeding 80 degrees Fahrenheit. It was designed to be mounted from underneath a fixture, featuring four countersunk screw holes for secure attachment. Additionally, there is ample space beneath the light and fan channels for neatly organizing excess wiring. A recessed area above the light allows for mounting a piece of plexiglass or glass. The following components were used in the construction of this light fixture: Luxrite LR21303 7W MR16 LED Bulb, 12V, 50W Halogen Replacement: https://www.amazon.com/gp/product/B01B1PLKYW/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 LE DC 12V 2A Power Supply Adapter, AC 100-240V to DC 12V Transformer: https://www.amazon.com/gp/product/B019Q3U72M/ref=oh_aui_detailpage_o08_s01?ie=UTF8&psc=1 Mini Bi-Pin Socket up to 75 Watts Ceramic Body with Mica Covers for Light Bulbs with Base GU5.3, G4, MR11, MR16: https://www.amazon.com/gp/product/B00DQGL9T6/ref=oh_aui_detailpage_o08_s01?ie=UTF8&psc=1 30mm x 30mm x 10mm 3010S 12V 0.13A Brushless DC Cooling Fan DT: http://www.ebay.com/itm/30mm-x-30mm-x-10mm-3010S-12V-0-13A-Brushless-DC-Cooling-Fan-DT-/262452197776?hash=item3d1b5eb990:g:xJgAAOSwNsdXRHtP Included are the 123d Design file as well as the STL file.
