Testing one the sections of the work table light

A project log for Work Table Light

The goal is to learn about ADC as well create a custom and unique work table light.

After building the structure and having a close to completed circuit I thought it was time to figure out how the table light was going to work.

Of course from my schematic I mentioned that there will be 3 "sections" to this light. However I had no idea how many pieces of the LED strips I needed, how many white LEDs I need in relation to RGB LEDs and how high off the table light needed to be from the working surface.

This is why I made a rough version of one of the sections from cardboard, duct tape and rope just to get an idea of what I really needed.

The pictures of them are below:

The connector is for the RGB led strip and 12V for the white LED strip. The loose wire to the right is for GND.

Attaching the cardboard to the underside of the top of the structure.

Held the section to the underside roof by using rope and duct tape.
Test to see if all the LED strips working as intended.

The best way to check the effectiveness of this section of LED strips is to view it in the dark.

Picture of white LEDs turned to max brightness with all other light sources turned off

This was the previous color for Nightmode. As you can see having the red LEDs at such high brightness defeats the purpose of a nightvision light.
It seems that the color strips are very bright to the point where it is almost uncomfortable, may need to add another interface to dim the color LEDs. 

Here is the planned colour for the Nightmode, will need to dim the colour more, but I like the fact that the green light allows me differentiate between colours better that the red light.

All in all it seems that the one section of LED strips has more than enough light output to lightup the whole working surface of the table. However in the daytime, the output may not be enough therefore I will still continue with 2 more sections.

Power consumption of the other 2 sections is not a concern since I will put an option to turn them off (via switches). Therefore having the option for more light when I need it.

Improvements to be made: 

  • Better cable management
    • Also easier access to ports of the LED strip (R,G,B,W)    
  • Better system to hold the LED panel sections
  • Dimming the colours in code 
    • Either hardcoding a dimmer version of all the colours are allowing the user to change the brightness of the colours
  • Adding something motorized
    • Planning on adding either a motorized shelf that can adjust level or have the sections adjust level or both.
  • Better user interface for the buttons and potentiometers
    • May put everything in a hobby box once everything is finished
