The mobile object Philips LED Stand was designed for the presentation of a series of LED lighting systems and other products from Philips, which started with the ArchitectureWeek - Light in Architecture event. The basic idea was to present interesting opportunities in the architectural objects enlightening using different types of lights that can be programmed and controlled centrally. For a practical demonstration of the idea and visual properties of these products a black cube with an edge of length of 3 meters was used, into which a dramatically shaped object was inserted. It was the prototype of a facade shading system at the 1:1 scale.

The project was designed to allow quick and easy assembly and disassembly. The basic framework consists of square tubes of cross-section 50 x 50 mm, which are anchored to the bracket and threaded rods fixing the metal plates of a thickness of 2 mm. The walls and ceiling are made of glossy black canvas. Flooring, lamellae slats and seating furniture are of metal sheets coated with chromatic powder coating. Thanks to the chromatic effect of the slats a perfect reflection of light rays from LED lights occurred that coloured the black space according to the programmed scene.

Organic shape is, due to the easy implementation and financial requirements, designed of individual linear elements. The resulting 3D curves are piled up from these items, creating a free-shaped surface. When changing the perspective of an observer, there occurs a transformation in the density – and the transparency of the structure changes accordingly. The object gradually opens and closes in front of the observer depending on the angle of observation. The organically shaped structure was possible to design and produce only by use of the parametric design method. Basic reasoning for parametric approach was not only to create a tool that would serve for searching the structure shape and its screening in visualizations, but which would also support the implementation itself. This tool should be the parametric object, at which it is possible to change the pre-set parameters - such as density or cross section of linear elements, the number of control curves, 3D texturing etc. Using the modifications of these parameters the visual and structural changes are made, even though the element still retains its pre-determined character. Thus can be changed the morphology of the flexuous surface based on functional and aesthetic requirements.

For the design it was utilized our software tool 'Parametric Waves', which we have already used with the implementation of Café-bar in Stare Mesto near Uh. Hradiste or by Parametric structure No. 2. In the project Philips LED Stand the script has been modified by the possibility of more complex 3D shaping of control curves. Added was also the possibility of lamellae slats distortion. These are, by achieving the given length, due to gain their reinforcement, twisted by 90 degrees in one direction and after that back again. The script allowing creation of a high number of variations was designed as a GDL - Geometric Description Language tool, which is a part of the ArchiCAD software. The basis of the tool is an active database of all the structure elements which are utilized in the construction. Each part has its own unique mark that carries all necessary information. By any changes in the parameters the database is immediately updated. Based on drawings and lists of structural elements it is exactly determined, where and what part is placed in the structure and what is its context with the surroundings. Without a complex approach to these attributes the assembly would be quite impossible.

With the project also the Philips lighting designer cooperated and worked on lighting simulations and assisted with the search for optimal variants of generated structures. Each of the selected proposals was then subjected to modelling of the luminous flux and luminous distribution. Simulation contributed to the proper selection of the correct type of lamps, their location and determination of the intensity of radiation. The main achievement was finding a suitable radiation angle and the angle of lights displacement, so that it could be possible to enlighten the structure utmost to its centre while making as much as possible of light scenes.
