Hi everyone! I have a question. I’m looking for a tiny RGB LED spotlight, as small as a phone flashlight, that can be controlled with an Arduino. It should be as bright as the iPhone 13 flashlight. Could you please suggest if something like this exists on the market?
DIY
This is the solution suggested by ChatGPT. I want a light like a mobile phone flashlight , which is focused and powerful , and at the same time I want to be able to produce colored lights. I want to realistically simulate the sunlight color throughout the day , which is not achievable with the LED proposed by ChatGPT .
- High-Power RGB LEDs such as Cree RGB XPE / XPG or Luminus SST-20 RGB
- Each color of these LEDs is High-Power, meaning you can combine RGB to:
- Create a strong white light (R+G+B)
- Produce colored light as well
- With a suitable TIR lens or reflector, the light intensity can reach tens of times brighter than a NeoPixel, almost like an iPhone flashlight
First; Nothing from chatGPT is achievable. You must guide it like a blind cat.
Noting will be "high-power" unless you want a 5kg "flashlight."
In defense of chatGPT, why can you not simulate "[skylight color] throught the day?" If you can't do it with RGBLED, you can't do it with anything.
That is not RGB... so no "skylight" other than white.
So, if I change my priority, the power of the LED becomes more important to me. I did some experiments using my phone’s flashlight, and now I’m looking for a very powerful LED, similar to a flashlight LED. Which LED would you suggest? I’m new to this field and don’t know which one would be appropriate for me.
Are you really asking which LED-flashlight/torch to purchase?
How will you know you have made the right decision if you do not study the field?
Search "flashlight (or torch) LED brightest circuit"... it's a matter of power-in equals light-out.
I would abandon RGB approach and try WWA (Cool White, Warm White, Amber). You likely have to build it by yourself with 3 separate led chips.
Or use multiple 5050 SK6812 WWA chips to reach needed power. Advantage here is that chips have built-in drivers.
Strawhat LEDs are very bright for their size, 5mm or 8mm, 0.5Watt.
They come in all the colours of the rainbow, including whites.
Leo..
You can buy LED flashlight modules.
I carry a Ledlenser P5 with me on dark nights. Not exactly top of the range, but bright enough to temporarily blind.
More powerful models are classed as "tactical" and definitely hazardous.
Heat management is important.
Cree seem to be market leaders in these high brightness devices.
Just an aside, some ship anti-piracy measures include extremely powerful searchlights capable of blinding attackers at long range.
"Nightsun" is popular with enforcement bodies like police.
