Going out into the street in the dark, we do not think at all about what kind of lamps illuminate our path. The main thing is to be light. Meanwhile, for people directly involved in ensuring the normal operation of street lighting, the choice of the type of lamps is a very important point.
ZhKU lamp - appointment
In a nutshell, the purpose of this lamp is defined as outdoor lighting. That is, in his power to illuminate any territory: street, courtyard, park. Due to the variety of models, you can choose the best option, which will also serve as a decoration.
ZhKU lamp - options of execution
By the type of fastening on the outdoor lighting support , these devices are cantilever. That is, unlike the floor lamps crowning the support from above, the ZhKU lamps are mounted at an angle of 70-75 degrees relative to the vertical of the support. Cases of various models of the lamp differ in shape: from a miniature (relative to others) oval (housing and communal services 06) to brutal, almost cubic (housing and communal services 77, "Elf PP", housing and communal services 28). There are spherical shells: ZhKU 19 and ZhKU 24 - "Selena". And the body of the Alpha model resembles an alien spaceship in shape. But the main thing is not the form, but the content: depending on the diameter of the base (27 or 40 mm), the type of ballast equipment (PRA) and the shape of the reflector, these or those lamps have different power, and, accordingly, should be installed at a higher or lower height.
The maximum power consumption that an LCD lamp can have is 400 watts, the minimum is 70 watts. Case material - metal with a corrosion-resistant coating or heat-resistant impact-resistant plastic. The material of the protective glass is lighting polycarbonate.
ZhKU lamp - type of lamp
The lamp deserves special attention, because it is precisely for its optimal operation that a lamp was created. In our case, this is a sodium gas discharge lamp (DNaT). Depending on the type of lighting fixture, DNaT of various capacities are used. For example: the ZhKU 250 lamp should be equipped with a lamp with a base diameter of 40 mm and a power of 250 watts. The advantage of sodium discharge lamps over mercury is that with the same power consumption, sodium gives a higher level of illumination. That is why municipal enterprises serving outdoor lighting networks, which are preoccupied with energy saving issues, prefer housing and communal services when choosing luminaires. In addition, the warm orange glow of the lamps is most comfortable for vision in the dark. Motorists note that driving on roads lit in this way is very convenient.
If the ZhKU 150 lamp is used in the courtyard area, the residents are very satisfied: the whole yard is perfectly visible, but it does not annoy the light of lamps beating through the windows at night. And what a night city the chains of orange lights running into the distance adorn!
Conclusion
In addition to all the advantages listed above, housing and communal services lamps are simple and reliable in operation. A sufficiently long service life and optimal cost determine the choice of these devices by specialists to ensure good operation of outdoor lighting networks.
