Modelling with initial framework and pvc leather.

After drawing a basic idea on Illustrator I discussed my frame’s design with a learning officer who advised that a system of 3 steel rods attached to 2 rings would be equally as strong and more visually appealing in the long run. I went on to crate a frame by braising the separate components together.

The frame pictured has been amended so that the steel plate now fits the reflector perfectly I also drilled two extra holes in the plate either side of the heat sink in order to attach two wires to hang the frame.

I’ve yet to add a hook to the cieling from which to hang the wires from,  as I will need to find a strong way of attaching the wires to the holes in the steel plate.

Cutting the pattern from the PVC proved to be very valuable as it helped me develop a method of even cutting. The laser cutter bed measures only A2 and so the leather had to be cut in sections. Using illustrator I sectioned off areas of the leather that would fit onto the laser cutter, each area has to be cut separately but match up in the end. Thankfully due to the scattered nature of this pattern , matching up the edges where each panel had finished was not too difficult.

Despite the large amount of issues to be considered,  I decided it was a good opportunity to now use the sample of laser cut PVC to make up a new model and identify any other possible needs.

The images show the leather is versatile and moved naturally over the frame but it currently sits on top of the heat sink and this is not acceptable. To allow for good ventilation I must design and create a new component to the frame work that will hold the leather up and away from the heat sink but also sit hidden within the form of the luminaire.

The wires attached to the steel plate hang the luminire level but need to be neat, a method of holding them central could be incorporated into the new component I plan to design.

The wires attaching the LED and the driver are currently red and black, this must be altered as it will stand out and look unprofessional against the white leather of the final model. This can be done by re-wiring the driver to white electrical cable and shortening the black and red labels.

A hanging mechanism must also be added to the ceiling to then hang the luminaire from, time restrictions may result in a functional design to begin with such as a small discreet hook. Eventually I’d like the ceiling rose fixing to become part of the design and reflect the high end aspect.

The driver sits neatly in the ceiling space away from the luminare but on the day of presentation Id like to hide it further by placing it above a disk of MDF that represents the ceiling.

Some of the spines on the frame where intensionally left long in order to arrange the leather’s form around them. The form is now decided and the spines are now perturbing from underneath and will need to be shortened to specified lengths before braising on the hooks that will help hold the leather in place.

This is a copy of the illustrator file used to cut the pattern from the leather. The orange markers showed me where the laser would begin and finish cutting allowing me to turn the leather accordingly in the laser bed.

The model  showed me there was a need to delete parts of the pattern around the peak of the luminaire as it revealed to much of the heat sink and frame underneath. On the illustrator pattern Iv’e now used guides to eliminate pattern that was in this area but also to mark where pattern edges began and ended.

To do list

  • Design and create new framework component that holds form, directs wires and creates ventilation around the heat sink.
  • The frame needs to be sprayed white to be less visible under the final leather shell.
  • The LED must be re wired so that the wires that appear from the top of the luminaire are white.
  • Hooks to  hold the leather’s form need to be braised onto the existing spines.
  • A strong method of holding the hanging wires to the steel plate needs to be designed.
  • Shorten spines so they aren’t visible from underneath the leather.
