6.5.1. The outdoor lighting control must be independent of the indoor lighting control.

6.5.2. In cities and towns, at industrial enterprises, centralized control of outdoor lighting should be provided (see also paragraphs 6.5.24, 6.5.27, 6.5.28).

Centralized control is also recommended for general lighting of large industrial premises (several thousand square meters) and some premises of public buildings.

Methods and technical means for centralized control systems for outdoor and indoor lighting should be determined by feasibility studies.

6.5.3. When using telemechanics in centralized control systems for external and internal lighting, the requirements of Ch. 3.3.

6.5.4. Centralized lighting control is recommended for:

outdoor lighting of industrial enterprises - from the power supply control point of the enterprise, and in its absence - from the place where the service personnel are located;
outdoor lighting of cities and towns - from the outdoor lighting control point;
internal lighting - from the room in which the attendants are located.

6.5.5. It is recommended that power supply for centralized control devices for external and internal lighting be provided from two independent sources.

The decentralized control devices can be powered from the lines supplying the lighting installations.

6.5.6. Centralized control systems for external and internal lighting should provide for automatic switching on of lighting in cases of emergency power outage of the main circuit or control circuit and subsequent restoration of power.

6.5.7. With automatic control of external and internal lighting, for example, depending on the illumination created by natural light, it should be possible to manually control the lighting without the use of automation.

6.5.8. To control indoor and outdoor lighting, control devices installed in switchgears of substations, power distribution points, input switchgears, group shields can be used.

6.5.9. With centralized control of indoor and outdoor lighting, control of the position of switching devices (on, off) installed in the lighting power circuit should be provided.

In cascade schemes for centralized control of outdoor lighting, it is recommended to provide control of the on (off) state of switching devices installed in the lighting power circuit.

In cascade controlled schemes for centralized control of outdoor lighting (clauses 6.1.8, 6.5.29), no more than two uncontrolled power points are allowed.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

The danger of e-waste 11.09.2008

One of the most common handicrafts in Chinese villages is the disassembly and disposal of used or obsolete electronic devices - computers, monitors, televisions.

As a rule, workers do not wear protective respirators. Meanwhile, poisonous compounds are used in all this electronics. The most important of them are flame retardants, which are introduced into the insulation of wires and into the basis of printed circuit boards to protect against fires. These are polybrominated diphenyl ethers that have a bad effect on brain development, memory, behavior, learning ability, the thyroid gland and the reproductive system.

Chinese scientists measured the content of flame retardants in the blood of the inhabitants of one village, 80% of which are involved in the disposal of electronic scrap. The poisons turned out to be three times more than in the blood of fishermen from a village located 50 kilometers from the first, and 200 times more than in the Swedish workers involved in the recycling of electronics.
