Lamp bulb holder E27 - High voltage

thingiverse

This is a dangerous build due to the high voltage involved. You have to know the dangers and potential issues: Short-circuits and loose wires. This build probably violates any good electrician guidelines. A lamp or bulb holder designed for the iDual LED bulb by Müller Licht or Jedi Lighting (http://www.mueller-licht.de/produktinformationen/artikel/400009/). But should fit any LED bulb. It can stand on a table or be mounted on a wall by a screw/nail. It is meant to provide electricity for the bulb by electrical contacting. Only for LED bulbs! No tungsten bulbs, these will melt the mount immediately. The cooling fins of the LED I use reach up to 70°C. But the screw base of the bulb is only below 30°C. The mount does not deform or melt. You will need two 10mm M3 screws and four M3 nuts, two paper-clips for inner contacting, a cable tie and a wire with a plug. As always a STEP file is included for easy changes and adjustments. Post-Printing The required steps in the following are documented as photos also. First you have to bend the paper-clips with pliers to create a nice contact spring. Then screw in the clips with the screws and fasten them with nuts from the back. You can check the contacting with a regular screwed-in tungsten bulb and a multimeter. You can correct the contact clips if necessary. Now take the cable and solder the ends to prevent single strings from going off potentially causing a short-circuit later. Bend the wires like a hook and fasten them with another M3 nut tightly. Be careful to not to create a short circuit. The gab is very small. Use a cable tie to prevent the cable from being ripped out. You can also fixate the cable by glue. Clean up the hooks from the back plate with a knife so they fit the grooves in the main body nicely. They are usually molten from printing.
