Seeking Feedback for Kit on Upcoming LED Design Challenge

rscasny
rscasny over 1 year ago

imageHi All.

As the new year moves on, so does element14's scheduling of new Design Challenges. That's what I want to talk to you about today. Specifically, an LED-focuses challenge. 

We haven't done much with lighting/LEDs (although Tariq may have when he managed Project14), but I have a sponsor who is interested in such a challenge. So, I'm exploring here how to make it work, both in terms of your interest in this activity, a propose challenge kit, as well as any theme it would cover.

In this discussion, I wanted to do a few things. For starters, to share with you the parts the challenge's sponsor would like to see in the design. Now, that does not limit us from adding parts to the kit. The next thing I want to do was flesh out the challenge's objective. Let me start with the parts. There's just a few of them:

1315050930002 LED, AlInGaP, InGaN, Red, Green, Blue, SMD, 120 °, Round, R 13mA, G 13mA, B 13mA

More Info

1313210530000 LED, AlInGaP, InGaN, Red, Green, Blue, SMD, 120 °, Dome, R 5.5mA, G 5.5mA, B 5.5mA

More Info

1312020030000 LED, AlInGaP, InGaN, Red, Green, Blue, SMD, 120 °, Square, R 5.5mA, G 5.5mA, B 5.5mA

More Info

1312121320437 LED, AlInGaP, InGaN, Red, Green, Blue, SMD, 110 °, Square, R 20mA, G 20mA, B 20mA

More Info

Here's a dual wire diagram for the product:

So, the above is kind of bare bones. I expect that there will be much more in the kit depending what the challengers would like to do. Now, what element14 would also include in the challenger's kit would depend on what you would want to do. A few random thoughts about it are:

  • Creative Lighting
  • LED Indication
  • LED Alerting
  • LED Alarming

The sponsor calls out what they see as the leading applications of their LEDS. They are:

  • Appliances
  • Industrial Control
  • Smart Lighting
  • Gaming
  • Decorative Lighting

Now is a good time for a poll:

So, I've offered a lot of information to chew about.

Just for myself, I think it would be fun to do something along the lines of Creative or Decorative Lighting. I would need to include prototyping gear, as well as a kit of support components. Enclosures I would probably not provide since many of you have 3D printers and have that capability; I also would probably not offer any test equipment as part of the kit, but you can always wish for it! I'd probably like to see some PCBs designed and built, with whatever solution you have available.

Now, if you were more interested in something more practical, the designs would require a larger and probably more extensive kit. I'm thinking industrial control panels etc. 

Thanks you for participating in the element14 Communities activities.

What Do you think? If you have the time, please vote in my poll and/or leave a comment.

    Loads of possibilities there.

    Might work for my infinity mirror Xmas tree bauble idea Slight smile

    There are also jewellery applications as demonstrated by mitxela:

    One of their LEDs is a 1616, that's not very big.

    What would you do with a 1010 addressable LED

    Tiny!

    Lots of dI/dt on a string of LEDs, the Ws2812 style LEDs are constant current.

    Still neat product.

    I was thinking more along the lines of pre-mounted to a carrier board something a bit like this:
    image
    5050 LED breakout PCB - 10 pack
    https://www.adafruit.com/product/1762

    but say ≈10 prewired together into a LED pixel strip or matrix that can be snapped apart at each LED something a bit like:
    image
    Breadboard-friendly RGB Smart NeoPixel - Sheet of 25
    https://www.adafruit.com/product/1558

    but with the data and power pre-wired across the snap points which then allows you to use it for testing as is but with the ability to snap it apart to use it with breadboard/protoboard or as part of a LED pixel wire string something a bit like this:
    image
    Breadboard-friendly RGB Smart NeoPixel - Pack of 5
    https://www.adafruit.com/product/1312

    to be able to incorporate it into the final project which may require different spacings.

    They have a Lighting Development Kit, which has PCBs kind of like what you described, along with driver boards.

    That is interesting, but I suspect the current gain 12-bit value is intended for use in white point colour balancing or global array dimming applications, while the PWM level 12-bit value should be the actual image data.

    I suspect the 12-bit gain + 12-bit PWM doesn't net you 48-bits of resolution since some of those values would likely overlap in terms of the effective current delivered. For example - 100% bright at 0% PWM is the same as 0% bright at 100% PWM, or 50% bright at 50% PWM is the same as 100% bright at 25% PWM, or 25% bright at 100% PWM.

    You might make the challenge more accessible if you can provide some pre-mounted on an evaluation board. Strips of say 10 that can be used as is as a strip or be snapped off into into singles that can be used in breadboard/protoboard or soldered into wire strings.

    Interesting info. Thanks for commenting about it. Right now, I'm getting the clear idea that the challenger kit will need to include a lot of LEDs.

    I can ask if Wurth wants to open it up to those LEDs. I was just given the ones I mentioned above. But it's early in the planning for this challenge, so I can ask. Thanks.
