cults3d

A super cheap and simple high power LED light. MADE TO USE WITH MAINS VOLTAGE! IF YOU DO NOT HAVE SKILLS/EXERIENCE PLEASE DO NOT MESS VITH HIGH VOLATGE!!! The heatsing at full fan speed can support upto 20w, I tested 30w but the i could feel the plastic case warming up. The fan is audiable at full speed, but turning the fan speed down to silent is still more than enough to cool a 20w led. I used a 1k potentsiometer in series with the fan to turn down the speed. When using a 10w LED chip the fan can be turned almost all the way down. The parts i used: The heatsink fan combo: https://s.click.aliexpress.com/e/_AKWH0P ---2$--- C8 (220v connector): https://s.click.aliexpress.com/e/_AKAtgf (5pcs) ---0.9$--- 220v/110v to 12v converter for fan:https://s.click.aliexpress.com/e/_9yWyYT ---0.5$--- (select the 1-3w version) 220v LED driverless: https://s.click.aliexpress.com/e/_AsEQGj ---1$--- (i used a grow LED light but you can find your own just make sure the chip is 220v driverless) TOTAL: about 4$ Of course some prices may vary, shop around a bit and find the best price. Many different LED chips should work since the sizes are more or less standard. I just use some super glue to stick the led chip to the heatsing. Using some heatpaste would be good, but i find the glue does good enough job for low power like this. If you feel comfortabe with the mains voltage then the wiring should be simple enough :) I bought this kit and that's where i got the speed controlling potentsiometer from: https://s.click.aliexpress.com/e/_9fxQVl Printed with 0.2mm layer high, no support and whatever infill.
