The most rational in this respect are light sources on high mast, down, evenly illuminating large surfaces and not glaring eyes. Tego rodzaju oświetlanie jest drogie ze względu na koszt konstrukcji i duży pobór energii.
Increasingly in places of intensive traffic, and especially the intersections of the thoroughfare of communication are set high lanterns, which meet these basic conditions.
Lighting of roads and squares of greenery is a point. Various types of tall lanterns are used for this purpose 3-5 m. The disadvantage of these devices is vision and uneven lighting. These defects are prevented by the use of various shades covering the light source and evenly distracting light. These inconveniences are difficult to avoid even with very low lanterns with sheltered bulbs, Because the lighting range is reduced then. Such low lanterns can be successfully used to illuminate interesting details in the garden. For road lighting, the number of such light points should be increased. However, increasing the number of lanterns is undesirable for plastic reasons. During the day, the lighthouses are clearly visible and disturbed the aesthetics of the object. Even the most aesthetic lanterns are not an ornament and it is difficult to composition with other elements of the garden. Much more favorable, in terms of the use of light and aesthetics, There are ways to illuminate the elements of the environment with lamps protected from eyesight. For this purpose, the light is directed to various spatial plant systems, building facade and on the planes of lawns. The lamps are hidden.
Lamps can be equipped with devices that allow the use of filters, and even their automatic change - like lighting devices in theaters. Devices regulating the intensity of light are also used.
All lighting devices should have an aesthetic form and a simple compact construction. In addition, high resistance to mechanical destruction is required, Due to vandalism.
The glass lamp shades were a huge problem for many years. Currently, new types of lamps are equipped with plastic shades, harder to damage. Vandalism in many facilities prevents the use of low lamps, connected with discovery cables running along the area of the area.
In order to reduce the risk degree, np. 24 volt. This requires adequate adaptation of the lamps, bulbs and other auxiliary devices.
All lighting devices work in the conditions of direct weather conditions. Rainwater moisture, and even dew, may cause a short circuit and damage to the installation. Therefore, these devices must be waterproof (hermetic).
