LED and street lighting
LEDs are semiconductor devices that generate optical radiation when an electric current passes through them. Until 1998, they were produced from arsenides and phosphides of gallium, aluminum, indium and their mixtures, and now production is being created on the basis of polymer semiconductor materials. The popularity of LEDs is explained by a number of advantages: low energy consumption, high mechanical strength and the ability to work in a wide temperature range, which significantly expands the use of LED lamps, environmental friendliness during operation and production, vibration resistance, long service life ( up to 20 years). Modern equipment allows manufacturers to change the size and shape of LED lighting fixtures, as well as the color schemes of the glow, brightness and power.
Such lamps are widely used in residential and communal services and are used on streets and in park areas. Gone are the days of the old lamps. The owners of private houses also use this type of lighting for safety and aesthetic beauty. LEDs are easy to use.But there are a number of requirements for street lamps that must be taken into account. They must have reliable protection against moisture and corrosion, which is why they most often look like space capsules, the material from which the lamp is made is important, strength and increased resistance to mechanical loads play an important role in production. A new development is the use of "anti-vandal" coating ", which will protect both from bad weather conditions and from" harmful "human actions."
To decorate residential plots, fiber technologies with end-light fiber are used, which create a "firefly" effect or a "luminous grid" effect, this technology is absolutely safe for electricity.
A novelty is the use of street lamps that are charged by the sun during the day, but the disadvantage of using them is that they are less bright and only serve to indicate some objects or a certain area, for example a path, a monument or a pond.
Nowadays, the use of the present invention contributes to saving money and bringing new sensations to people's lives.
