Lighting Installation Using Full-Spectrum Light Emitting Diodes

The project team designed white-light LED installations for a photographic light box, a floodlight, a microscope light ring and a soft box light bulb. The designs match or exceed the luminosity and light quality of existing products while remaining economically viable for manufacturing. The emittance requirements for each product were determined through radiometry data from existing products and their intended use. LED arrays were created based on the lumen requirements. The LED arrays are powered through a newly designed dimming-capable LED driver. The controller and driver board provide constant voltage and an input-controlled current to the LEDs, allowing dimming control in each luminaire. An AC-DC power supply converts AC input into constant DC that goes to the controller boards. Housings for each product were 3D modeled and 3D printed before the designs were sent to fabrication facilities for mock-up production.
