LIGHTING

One of the most important consequences of the development of electricity is artificial lighting. In developed societies, lighting is an indispensable and a human given factor of living. This is most noticeable when a power failure occurs in an area. Nothing works, there is usually confusion, and the fact that there is no lighting complicates the whole situation because one of the most basic, if not the most basic, of the human senses, vision cannot function fully in situations of total darkness.

In general, artificial lighting is essential in our daily lives not only for practical reasons but also because it affects man psychologically and physically. Depending on the space and the purpose of the lighting used, there are different types of lighting. So there is decorative lighting, work lighting, lighting for relaxation, relaxation and tranquility, lighting for isolation, lighting for social interaction. Also the type of lighting can influence and determine the mood of people in different ways (either positive or negative). There is lighting that causes headaches, discomfort, tension lighting, relaxation and even illumination used for therapeutic purposes. It is for these very reasons that we must be able to determine the illumination exactly as we need it.

Research on different categories of use shows that energy consumption for lighting amounts to:

Office buildings30-50
Stores25-50
Hospitals10-20
Hotels10-25

For the choice of lamps, the consumer should carefully consult the energy label of the lamp. The energy label provides information on the lamp brightness (lumen), power (Watt), lifetime (operating hours) as well as the energy class of the lamp, in A-G energy efficiency (descending order).

In addition to fluorescent lamps, alternative lighting technologies such as upgraded halogen lamps, xenon gas filling, LED light emitted diodes and high-discharge sodium lamps offer significant energy savings.

Installation of lighting sensors in areas where there is no need for permanent lighting is another measure to save energy in lighting. The sensor activates the lamp to operate only when there is movement and for a time that the user can specify.

There is also a choice of lighting sensors with photocells that turn on and off the lights depending on the amount of daylight available as well as the timers, which adjust the lights on and off depending on the use of the spaces. In any case, the best way to save energy on lighting is to maximize the use of natural light and rational use of artificial lighting according to our space and needs. In addition, a photometric study by experts can determine the exact lighting needs of buildings and outdoor spaces.

There are also many other ways to save energy on lighting, which do not require any extra financial burden but relate solely to the correct behavior of their users.
