Lighting fittings iGuzzini for public lighting
There has been a very popular discussion recently about the problems of light pollution. On the one hand, there are lighting technicians who argue against the energy expensiveness of the design, which is from the point of view of lighting absolutely unreasonable, as if the aim of the design was to save electric energy and not lighting itself. On the other hand, there are astronomers who argue against the disturbing effects of light, though they often observe the stars on other wave lengths than the visible lengths and they try to bring to the discussion themes that nobody would ever intend to consult expertly with astronomers (the impact on flora and fauna). Both camps set themselves in their positions and because they do not have enough courage to come out and admit that they may not know everything. They would rather commit “seppuka” than ask others. This is a short characterization of the current state of the problem of light pollution in Czech Republic that developed quite progressively at the beginning. Unfortunately, no sufficient expert platform was created to solve it. The situation in Europe is, thanks to respect and tolerance among those who discuss it considerably different and there is a chance to find solution that does not have to be an ideal one, but it would be a better state than the current one. However, as our company has paid add in this magazine, I have to come back, from this generally non-commercial theme, to the theme of the company we represent. I will make use of the light pollution as well.
In the second part of the 1980´s, the theme of light pollution was quite enough discussed a problem in the US. This discussion penetrates Europe, with some delay, at the beginning of 1990´s. iGuzzini company started to deal with the problems in their beginnings. iGuzzini realized the complexity of the issue, the necessity of a wide informational campaign and creation of a platform for expert discussions. Aside from the informational campaign, iGuzzini began, in cooperation with American company Devine, to develop outdoor lighting fittings of the class „cut-off“, with the same name. Originally, the whole system consisted in four types of lighting fittings Tebe, Delphi, Delo, Argo, with four types of optical systems according to the classification IESNA (USA): optics II, III, V and asymmetric. Gradually, used optical systems and types of light sources were innovated. In parallel, the development of other systems of outdoor lighting began. Currently, the offer of iGuzzini outdoor lighting of the class „cut-off“, that is distinctive for its design and quality of manufacturing, is one of the widest.

PLATEA
System Platea, historically the second system of the class „cut-of“ by iGuzzini, uses floodlights (with the same name) by an Italian architect M. Cucinelli that can be placed, using the arms, on the wall or on a pole. The standard attachment of the system includes conic poles 4,7 and 9m high. For the lighting of communications, floodlights with illuminance curve of a „butterfly“ form are used. Owing to the fact that the system makes it possible to use even other types of optics of the original line of floodlights, the possibilities of lighting of city areas of various forms and sizes are extended. Lighting fittings can be furnished with metal-halide or sodium lamps 70 or 150W, they have the isolation class II and the covering of the optical part IP65.

BERLINO
The form of lighting fittings Berlino draws on originally indoor lighting fittings of „industrial design“ by architect R. Piano. The lighting fittings are intended for lighting of city, open spaces and they can be furnished with compact fluorescent lamps, metal-halide, sodium or mercury lamps with inputs 70 and 150W. The system includes a pole that is 5m high or a wall arm. Lighting fittings have the class of isolation II and covering IP65.

ESTE
Design of the lighting fitting Este comes from three well-known Italian designers M. Albini, F. Helg, A. Piva. With respect to increasing requirements on limitation of light flow radiated to unfavourable directions, the original optical system of lighting fittings was revised. Lighting fittings can be furnished with sodium and metal-halide lamps 70 and 150W and fastened to the wall or to an atypical pole with a square section 6m high. Lighting fittings have isolation class II and covering of the optical part IP65.

CITYWOODY
The system of lighting fittings CityWoody stems from the series of floodlights MaxiWoody and it enables the using of small and medium types that can be furnished with sodium or metal-halide lamps for inputs up to 150W. Conic poles 4 and 7m high are added to the lighting fittings. The lighting fittings are fastened to a pole with profiled arms through which it is possible to fasten on the top of the pole one or two lighting fittings. With 7m high poles, the lighting fittings can be furnished in various heights. This ordering makes it possible to illuminate communications for cars on the one hand and foot-paths on the other. Owing to the fact that the lighting fittings come from the original line of floodlights, it is possible to complete their optical system with original accessories that enable to change the form of illuminance curve. Lighting fittings have isolation class II and mechanical resistance IK08.

FRAMEWOODY
Similarly to the system CityWoody, FrameWoody system comes from the line of floodlights
MaxiWoody. In this system, floodlights are linked up to greater wholes and they create a light spot with more light sources. The ordering of the system enables its simultaneous use for public and display lighting. The lighting fittings can illuminate both neighbouring objects and facades of buildings placed above the level of lighting fittings. Poles 7 m and 9 m high are parts of the system. The lighting fittings are designed also in the form ready to be fastened on a facade or in a suspended form. The system can be furnished with all types of floodlights (optics) with inputs 70-150W. These lighting fittings have isolation class II, covering IP67, mechanical resistance IK08.

FLAMINIA
The design and formal lay-out of this system comes from Northern environment and its author is arch. Jan Wickelgren. The system consists of four rows of lighting fittings Flaminia A, B, C, D. Type A is furnished with optical system of the class „cut-off“ and it can be used for lighting of car traffic communications. The poles that are 4, 6 and 7m high are part of the system. The lighting fittings can be furnished with metal-halide lamps with inputs 70 or 150W. When designing lighting fittings Flaminia, attention was paid also to the formal design of the pole whose curves come from pure inspiration but they also have their own logic. This logic consists in widening of the pole in the area of distribution frame doors where problems arise both with the size of distribution frame and with connection of lighting fittings. Lighting fittings have class of isolation II, covering IP67 and mechanical resistance IK07.

SALARIA
The form of the lighting fittings SALARIA originally comes from outdoor lighting fittings with ball-shaped or oval polycarbonate coverings. They take into account requirements on restriction of the light flow radiated from the upper half-space. This system’s design offers flexibility both regarding the turning of the arm in holder around the pole and the turning of lighting fitting around the vertical axis in an upper pivot. This enables to optimise the direction of the light flow, with the required ordering of the lighting set. Poles 5 and 7 m high are added to the lighting fittings. The lighting fittings are supplied standardly in a version for combined operation (full performance/half performance). Lighting fittings with 3 possible types of optical systems can be furnished with halide or sodium lamps with inputs 70-150 W. Lighting fittings have class of isolation II and covering IP65.

LES ALPES
Outdoor lighting fittings Les Alpes were designed in the year 2002 within the frame of Generel of the city lighting of Italian mountain centre Cortina d´Ampezzo. The system of lighting designed by Giovanni Albertini enriches the character of city Cortina with a typical component of the city mobility and, at the same time, it meets the strict requirements of region Veneto that deal with light pollution. The more restrictive requirements on the reduction of light pollution come also from the fact that there is an astronomical observatory Col Drusie close to Corini d´Ampezzo. Lighting fittings can be furnished with halide and sodium lamps. The project in Cortina was one of the first applications of halide lamps with a ceramic burner (CDM –TT). The form of the lighting fitting is rather specific. However, as to the look, it fits in the environment of the mountain centre. Lighting fittings have class of isolation II, covering IP65, mechanical resistance IK07.

LAVINIA
The series of lighting fittings Lavinia is the latest series of outdoor lighting fittings of the class „cut-off“. It was designed for outdoor lighting of a new expository area in Milan where this year’s exposition Intel will take place as well. The author of design of the area and of lighting fittings is the Italian architect M. Fuksas. The shape of the lighting fitting came from the taking-over of the characteristic shape component of expository halls. Lighting fittings can be furnished with sodium and halide lamps with inputs 250 and 400 W. Poles 6, 7, 9 and 10m high are part of the system. During this year’s exposition Intel, there will be presented lighting fittings of lower inputs. Lighting fittings have class of isolation II and covering IP66.
