Hey everyone.

Just found this forum as I am looking for a bit of help on RGB LED lights. The plan is to build a moving-head as seen at concert stages etc. It's a little project where I'd like to make a couple of battery-driven moving-heads that communicate using WiFi, but I'm currently struggling with finding a proper LED emitter. I've also considered getting a lense, but I have never gotten any furhter than understanding the physics. I am looking for a 3-5W RGB emitting source that can be controlled by a microcontroller like ESP32. And if necessary a lense at around 30 deg as well :D

I've got a laser-cutter and a 3D printer at my disposal for the creation. I'm really only missing a lightsource :D

What do you think?

Thanks in advance!
Nice forum you've got!

Would this be considered a type of "fixed lighting" ?

I realize you are talking about moving parts, like a spotlight or searchlight might track something, but is the fixture itself (luminaire) stationary ?

You might want to look at projection optics, you can use many different shapes and sizes of light source if you use lenses to focus the light. You probably need a couple of Fresnel lenses and a triplet.

A lot of people make DIY LCD projectors, you could do something similar but replace the "screen" with a gobo and/or gel.

Thanks for the feedback. I would like for the LED to be RGB rather than just white. This is battery-driven, so I don't want to waste the power :D I plan on just making it show colors with no patterns :p I'll see if I can find projector-like LEDs that are RGB and can be controllable with Arduino.

It's a stationary lamp (Fixed to a rack). The LED emitter is attached to some actuators, so actually the LED itself is moving about.
