Street lighting: modern comfort and innovative ways
Street lighting - special devices and appliances for creating artificial light on the street at night, evening and early morning. As a rule, devices are attached to poles, masts, viaducts and other supporting fixtures. Lamps at night can be turned on either automatically or controlled depending on the wishes of the person.Outdoor Lighting - Key Attributes
To create lighting devices that are operated in street conditions, a wide variety of materials and accessories are used (glass, wood, steel, aluminum, forging). However, a review of lighting fixtures is always recommended to begin with a study of light sources. Lamps according to this principle are classified as follows:- Incandescent lamps work by heating the filament with an inert gas. Halogen lamps are one of the subspecies of incandescent lighting elements. Compared with the "classic" forms, they work longer. Convenient to use, both outdoors and indoors;
- Discharge lamps. As a light source, gaseous fuel processing is used. It causes the formation of electric charges of a given power;
- Xenon lamps are fixtures complemented by built-in arc lamps. The light source is an electric arc that burns between the electrodes. Depending on the internal content, there are various options for the type of spectrum of the emitted light flux;
- Fluorescent lamps are devices that are considered the most durable and reliable for street lighting. Launchers and regulating installations, electronic types - a modern type of fluorescent lamps were previously produced. They work quietly, do not create an unpleasant flicker;
- Induction devices are gas discharge lamps that do not contain electrodes. The light source is plasma. It arises due to ionization of the gas.
Varieties of gas-discharge type devices
Gas discharge lamps are popular, despite the fact that there are many more modern alternative solutions for organizing street lighting.Gas-discharge lamps are characterized by high efficiency, a long period of operation and fairly good aesthetic qualities. Lamps are divided into such types:- Mercury. They operate on the basis of discharges arising in mercury vapor. It is advantageous to use devices for the improvement of large locations, since these types of lighting devices are very economical;
- Metal halide. They contain various additives that correct certain characteristics of the lamps. They are distinguished by special power and are often used to design open spaces of a large area (sports grounds, huge architectural structures, stage platforms);
- Sodium. Through the use of sodium, it is possible to obtain a powerful and stable electric charge. This variety is appreciated for a particularly comfortable stream of light (yellow-orange, diffused).
Classification of luminaires for creating street lighting
Lighting devices can be presented in a variety of forms and modifications: like traditional lights or elements with shades, modern lamps or spotlights. Luminaires, based on a number of key operational parameters, are classified as follows:- Classic format;
- For the park;
- Economical varieties consuming, under special conditions, a record low amount of energy;
- Lamps with light reflection installations;
- Indirects
- Devices for installation on the type of horizontal and vertical.
