Mini Photo Studio Light

Update 09.08.2023

Improved Arca swiss mount and added cold shoe and light stand adapter. Requires M4 bolts and 4-5mm Threaded inserts. 

This mini Photo studio light was created out of a need to have reliable high-quality lighting in the 10-30W range (ca 1000-4000 lumens).

The design is based around VGA heatsink/fan assembly that is cheaply and readily available on Aliexpress. For the LED, an F17 package (19x19mm) works well this must then be glued to the heatsink with thermal glue. I recommend using a LED with a CRI above 90. 

The forward housing will accommodate a reflector with a 50mm diameter, two lengths are included depending on the reflector/LED combination.

The body of the light is designed to fit a custom PCB with a Rasberry Pi pico used to control the LED through a Meanwell LDH driver. In this configuration, brightness can be controlled and the fan operation is temperature based with an OLED displaying temperature and brightness. 

A simpler design can however be built without the Pi, with the housing having adequate space for a variety of LED drivers. 

The rear plate should be selected based on the use case, with a variety of power supply options included.

New mount adapters will be published in Feb.

Print settings: Print as oriented in ASA, PETG or PLA. Note with PLA warping may occur on parts touching heatsink, depending on LED used or settings in Pi.

 Supports not strictly required but can be used for overhangs greater than 40 degrees, I recommend a skirt on the barn doors if oriented vertically.
