Applications & Implications
What will it do?
A color- and brightness-adjustable LED-lamp that imitates sunlight during the course of the day. It oscillates between warm (~2500K) and cold (~5000K) white, synced with the sun, based on its location. Features a smartphone app.
Who’s done what beforehand?
I’ve done a small experiment in that direction about two years ago, using a pre-made Arduino, pre-made LED modules and PT4115E driver boards.
What materials and components will be required? / Where will they come from?
- Electronics (lab stock / farnell)
-
- external wall adapter (24V 2A) (lab stock)
-
- Copper sheet for the heat sink (lab stock)
- Housing
- Glass pipe (local glass blower)
- Composite (raw materials from lab stock)
How much will it cost?
What parts and systems will be made?
- LED modules – arrays of two different types of LEDs, separately controllable
- Controller Board - based on ATMega328 / I²DC two filtered PWM channels, serial bluetooth interface
- Housing – Glass pipe + end caps
- Physical UI
- Android App
What processes will be used?
- PCB Milling
- Reflow Soldering
- CNC Milling
- Composites
- 3D Printing
What tasks need to be completed?
What questions need to be answered?
What is the schedule?
How will it be evaluated?
- Successful production of the hardware is necessary. This includes:
- Molding the shade
- Casting the end caps
- A working 2-channel PWM driver is required
- Smartphone control is mandatory (color & brightness)
- Sun tracking is optional
