[DESIGN] - Lighting #27
Description
Design Scope
Design a wide-spectrum controllable LED lighting system.
Deliverables
Outline the implementation prototype and its components:
- LEDs (types, quantity)
- LED Drivers - NLDD series
- Topology Adaptation, Fusion 360 EDA
- Multiple LED-only daughter boards, wired in series
- Two 6-pin (5 LED + GND) Molex Micro-Lock PLUS connectors (one
+, one-) - How many LEDs per series per daughterboard? 3 per series
- Power Route Widths
- Two 6-pin (5 LED + GND) Molex Micro-Lock PLUS connectors (one
- Single power board
- Voltage requirements for all LEDs in series? 4 boards = 12 LEDs, max. ~38V for blue
- Power Route Widths
- Pull-down resistors on master control board for each PWM
- Multiple LED-only daughter boards, wired in series
- Lighting performance enhancement (diffusion/lenses)
Requirements
List any applicable metrics with criteria/constraints:
- Covers maximum possible PAR requirement
- Spectrum range from near-UV to near-IR
- Intensity from off to welding arc

Not sure if Cree LEDs are being phased out...

Correction: they are not being phased out, i'm just an idiot. There are tons of CREE options on DigiKey. Might have to do a more rigorous selection process.

The lighting system had an overhaul. Need to update all designs and documentation
