New Floodight Board

[stampedeboss]

I've designed a new floodight board the supports anything from 10w to 100w using the same board and components. I eliminated soldering the led directly to the board since LEDs very by wattage and layout. I was wondering if anyone would be interested in it. I designed this to address my changing needs for different powered floodlight and I can now change power simply by changing out the LED.

The board is 30mm x 40 mm and fits into the back or lower compartment of the floodlight housing and you connect to the led via wires. It supports voltages from 12v to 60v. This design is based on a new controller chip that recently became available and is price competitive to the PT4115 that is used in Pixiflood and Rob G's boards. An additional feature is there is a "sidecar" capability for a submodule which adds pixelstick capabilities to the flood light. The nice part of the sidecar is it can be connected and disconnected without tools or soldering. It make it easy to use it to test the assembly.

I have also used the board to drive strings of dumb pixels from smart controllers, It can control up to 3 strings from a single board since floodlights can be treated as 3 channels.

Let me know what you think.

I’m interested.

I see you’re in the DFW area. Are you a member of the North Texas Light-O-Holics group? Would love to get my hands on one or more of your boards to play with

Yes, this is certainly something very useful!!

No, I hadn't heard of them but would be interested. I just sent off for another batch of boards. Here's what the board looks like with the side car.

FYI my intention is to make the board open source.

This picture shows the relative size between from top to bottom, the original PixiFlood 10W board, my Pixiflood with a built-in pixelstick, and the new board on the bottom.

Do you have any photos of it assembled? Sounds pretty cool.

Sounds great, I will certainly be following this closely to try out! Thanks for doing this!

We typically meet in Plano monthly after taking a couple months break for Christmas. I’ll PM you more details.

typo on the constant current driver I used, https://www.diodes.com/assets/Datasheets/AL8862.pdf for those interested. What made it work from those available was 60v max and under a buck a piece.

definitely interested!
