Prototyping

Now the aesthetics of our design have been finalised we have set about creating a prototype of our piece. We have collated all the information we have gathered and begun to craft all the components.

Glass Lampshade

To create the glass dome for the top of the lamp we firstly had to fuse pieces of clear glass. These were recycled from unsuccessful blown glass pieces.  Once this had been done the sheet was slumped into the correct shape of ceramic mold. Any sharp edges are then sanded down with wet and dry paper and diamond pads.

Wooden Base

For the base we chose to use wood as we wanted to contrast a number of materials within our piece. Although wood will be used within the prototype we feel this element of the lamp could potentially be made from a wide range of materials from ceramics, to metal or cast concrete.

We initially considered having a solid piece of wood CNC routed, however after speaking to technicians we have been advised this would weaken the wood. Also as the bed of the router isn’t deep enough it would have to be created in several layer. In order to have a more accurately cut piece we have opted to  cut the base piece in layers which will then be glued and clamped together to create a solid piece.

We will also create a sample using a solid piece of wood which will be hand turned. This would have a nicer aesthetic than layered boards, but would be more costly to reproduce.

Acrylic Lid & MDF base pieces

The lid which will cover the electrical components will be cut from mirrored acrylic as this will reflect the colourful patterns of the glass, experimenting with distortion and reflection. The MDF components of the base which will hold the light sockets in place will also be laser cut.

 

Wiring

Next we had to correctly wire the components together for the light fittings.

As our design requires three 5W lamps the circuit needs to support 15W (65MA).

The light fittings will be connected by 250 volt / 3 amp connectors, and 3 way supplies will accommodate L.N+E conductors. This will permit the base to be numerous material including metal, as it will be earthed.

Coloured LEDs

For the bulbs we have opted to use remote control, changeable coloured LEDs. These will allow the user to determine whether they choose white lights, red, green and blue light (to create chromatic shadows) or a combination of colours to suit their mood. But adding the ability to modify the product we hope it will prolong the interest as users interact with it and connect with it.
