Raffaele De Vita deconstructs “Molecula” and "GalLED"

(Lighting Designer: Raffaele De Vita)

In Italian, “to give birth” is “to give to the light”. Before “giving to the light”, every design concept should go to the essence of its aim. After being deconstructed, the idea is ready to be reconstructed as a concept for future design and it is with this philosophy that the luminaires “Molecula” and “GalLed” have been conceived.

The first aim of the Molecula was to illuminate the large hall of a ten-storey building in a thoroughfare near to the elevators and stairs, where people went to their offices. This was a “no genius loci”, from the Latin, “a place without soul”.

As lighting designers, Claudia Campana,  Paolo Tari’ and I likened the hall to a large incision in a very compact body. As the essence of a body’s deconstruction is found in its ‘DNA, our idea was to use the light as if it were the DNA of the building, visible in its cutting and reconstituted in new and changed forms and scales.

Three different lighting elements were repeated, rotated and intersected, employing a junction with the capability of connecting, lighting and dissipating the heat produced by the Led technology placed within. All the modules together created a vertical structure whose strength was contrasted by the lightness of the principal material chosen: polyethylene or alternatively PVC.

Particular features of polyethylene include that it is washable, impact resistant, resistant to cold, has anti UV colors, long life and most importantly in case of fire, it is self- extinguishing. The material is very commonly used in public space and is simple to produce.

My design, the luminaire GalLED, has been projected for the access zone, the threshold zone and the interior zone of three lane tunnels, and is adaptable for two lanes.

The core of the GalLed technology is the PCB (Printed Circuit Board) that, following the curve of a standard tunnel, helps the LEDs to create an asymmetric photometry.

The power supply is located on top of the luminaire, where it attaches to the structure of the tunnel. The power supply works like the manual shift knob of a machine: pushing it activates a mechanism that allows the user to rotate the device.

The industrial process chosen for the production of the shell is the die casting which employs the use of fins, crucial for proper heat dissipation, thereby overcoming one of the weaknesses of the LED technology

The fins are designed to follow the curve of the body, reducing the storage of pollutive chemical agents on the surface which arise due to the lack of ventilation and air circulation.

GalLED is a 40 Led luminaire, 125 Watt, IP 65, made of anodized aluminium to increase longevity and corrosion resistance.

It is possible to customize the product with brand colors. Both the luminaires have been tested with software, although the prototypes have not yet been realised.

Raffaele De Vita is a Lighting Designer with a background in Architecture. He worked in Rome at Fabertechnica S.a.s. as a Lighting Consultant and Manager on a different range of projects for clients like: Vatican City, Terna S.p.a Energy Distributor, ABDR Architects for the new Tiburtina train station in Rome and researched about Led, Lep, Hps, Hid lighting technology.
