LED-ILLUMINATION Reflector

This interesting project is about printing a 3D model to assemble and build a LED floodlight with wall bracket, using 3D printing technology.

STL files are provided to print all the parts.

The model consists of a frame to place four (4) 135x10 mm segments, cut from a conventional 1 m LED strip, with 30 or 60 leds per meter, as desired, and a 220/5V DC 2A source inside (it has interior space for it).

The LED strip segments, are fixed on the LED support piece, and are connected by passing the wires through the slits provided for this purpose. In the end there will only be 3 wires (+Vcc, GND, and ENT signal) that will be connected to the power supply and LED driver, which are both located behind the LED holder, in the box.

Four pillars allow the enclosure to be closed and the LED bracket to be attached.

For fastening, 15x3 mm screws can be used on the back of the box.

Glue or EVA type silicone glue should be used for fixing the poles to the LED holder.

The source wires (220 VAC) can be pulled out through the center tube of the universal bracket.

The power supply can be external or internal. External outside the box. Internal inside the box. In case of internal the power supply must be board type.

Specifications: 220V VAC 5V DC 2 A

The universal bracket, is a second part consists of a fixing mechanism which is used to fix the LED reflector box to a wall, for example.

The parts print on any 3D printer and the model has been broken down into parts to facilitate proper printing.

It can be printed entirely in PLA.

The images provided show how the reflector assembly is assembled.

This project requires dexterity or skill to assemble and configure the electronics around the LEDs.

The printer used is the Ender 3D pro. With the following parameters:

-Nozzle: 0.4

-Layer height: 0.1 mm

-Speed: 60 mm/s

-Temperature: 210 °C

-Heated bed: 60 ºC

-Support: RAFT
