The halogenous
projectors of light must be placed of different form depending on the zone that
is going away to illuminate and the use that is going away to give to him this
zone.
The main fields of
application of the illumination with halogenous projectors are:

The halogen
projector TECNOCEM are made with the norms of the CEE.
1 - Illumination
of work areas of industrial areas
The areas of work
or industrialists is great outdoors located zones, like zones in construction,
parkings, loading platforms, ports, parking, etc... The halogenous projectors of
work usually settle to each other grouped in separated high posts of 1' the 5 to
3 meters, facilitating therefore movements in the work zone.
This way, also the
lights outside the angle of view are able to diminish the problem of the glare
when being. In these facilities usually they are used sodium lamps to high
pressure and those of metallic halogenuros.

2 - Illumination
of buildings and monuments
Although the
buildings have been designed to see themselves by day with the light pave,
interesting effects can be obtained at night and with a suitable illumination
that attract the attention of the passers-by on such. It is question to apply
imagination, creativity, aesthetic and technical to each particular case.
To time of
illumination buildings with halogen projectors it necessary to distinguish two
cases:
In the first place
the functional buildings, with simple facades without remarkable decorative
elements, like the typical buildings of crystal facades, where a uniform
illumination is applied, of flat aspect and without relief. They have the
advantage which few points of light are needed although the situation of the
halogenous projectors, far from the building, can be a disadvantage.

Secondly we
have the buildings with remarkable architectonic elements like cornices,
frisos, reliefs, etc... that need a special treatment, an illumination does not
uniform, that heightens these elements and creates an impression of relief by
means of games of lights and shades, resistances of color and/or brightness,
etc. For it, projectors of work placed strategically in the facade are used
trying to diminish the damages in the same one.
Useful advice
before beginning are to study the directions and observed range that will serve
to determine where to place the halogenous projectors. To analyze the
environmental luminance considering that while greater she is this, greater will
be the necessary luminance so that the building emphasizes. To see what
obstacles there are presents in the direction of observation like trees, fences,
fences, etc.; in these cases he is recommendable to put the centers of light
between the building and the obstacles so that their silhouettes are only seen.
To increase the luminance of the high part of the building to increase its
height apparent, to eliminate shades wished with projectors located on the
facade or not increasing the distance of these to the facade, to take advantage
of the effect mirror on the water, etc.

The luminance
levels depend on the characteristics of the used materials (reflectance, texture
and color) and of the luminance of the environs. As a example we can mention
that the illumination that needs the calcárea stone is of 40-320 lux, the
granite of 50-500 lux or the brick of 30-500 lux. As we can see, they are very
ample intervals whose values depend on each particular case.
The lamps to use
very are varied and depend on the effects that we want to obtain. Most normal it
is to use metallic mercury lamps to high pressure, halogenuros (when a good
reproduction of the color is required) or sodium steam (material stony of warm
tones).

Another form
to illuminate a building with placed halogenous projectors in different places.
3 -
Applications in road lighting system
In this field the
halogenous projectors are reserved for the illumination of seat, communications
centers, parking and in general of any other situation where the installation of
traditional lights supposes complications for the direction, technical
difficulties, etc. They present/display the advantage of which they simplify to
the installation to the salary less points of light and produce one more a more
uniform and pleasant illumination.

4 - Illumination
of sports instalation
The objective to
illuminate with halogenous projectors the sport facilities or is inner or outer
it is to offer an atmosphere adapted for the practice and benefit of sport
activities by part of players and public. Logically, the exigencies will vary
according to the type of installation (recreation, training or competition) and
the level of activity (amateur, professional or broadcasting by television).
To illuminate this
type of facilities is not easy, because there is to make sure that the players
and other sprites are perfectly visible independently of their size, position in
the field, speed and trajectory. For that reason the value of the horizontal
iluminancia like the vertical is important as much, although actually this last
one only considers in the televising broadcastings where a good one is necessary
modeled that it emphasizes the forms of the bodies.

In order to avoid
glare problems that make difficult the normal development of the game, specially
in sports where there is to watch upwards, it agrees to take measures like
installing screened lights, reducing to the number of light points grouping the
halogenous projectors or to avoid perpendicularly to place them to the main line
of sight. He is advisable to mount the light sources to a suitable height; for
the case of outer facilities and sight from the center of the field, the angle
formed by the horizontal plane and the axis of any halogenous projector of the
battery must be superior to 25º.
The lamps to use
will depend on the purpose of the installation. In competition facilities, lamps
of metallic halogenuros by their high benefits are used. But in other cases it
can be enough with halogenous lamps or of mercury and sodium to high pressure;
more sales.

Correct
halogenous illumination not to bother the clients of a gymnasium.
The lights, in
outer facilities, are arranged normally in towers placed in the lateral ones,
the corners of the field or a combination of both. In the first case rectangular
projectors are used whose projection on the land has trapezial form obtaining
like added value a good one modeled of the bodies. In the second case the
circular ones are used that gives a projection in elliptical form.
