The LED lighting systems for the compilation of a number of additional savings is possible.


LED light source systems provide several additional savings when they are created. These always depend on scheduled and actual situation. You have to examine in every case what other advantages can provide constructing a LED light sources system apart from being economical. These can be the following:

  • using wires of lesser cross-section
  • better use of existing energy quantity
  • occasional network development can be omitted
  • less use of electronic control
  • using cheaper distributor devices
  • overvoltage protection
  • reducing stroboscope effect
  • no sparks
  • light sources replacement in groups
  • long lifetime
  • slow failure
  • industrial safety effects

Electronic controls are one of the novelties protected by a patent of LED ligthing systems developed and manufactured by our company. The point is that they do not contain a transformer but semiconductors exclusively thus we can avoid unnecessary energy loss at the very most. Apart from controls our LED systems have another electronic solution included (patented too) which provides light source's stable operation even if input voltage fluctuates. Our designing engineer have set as limits of voltage fluctuation 80 V and 280V. There are no mains voltage under or above these limits. This solution resulted in an important lifetime extension because LEDs are sensitive to voltage fluctuations. Another property of fitted electronic controls is that they can reduce human eye sparkling perception. It reduces stroboscope effect, so it can be used at revolving and moving machines, contrary to neon lighting which turns on continuously from both ends given by its operation. As a result in given places you can not use neon, only traditional incandescent bulbs which demand a lot of energy. Light sources distributed by our company do not have this problem, they can be used near by rotating machines. Our light sources operate mostly at 12 V, in case of failure (breaking) there will not be produced any sparks between Anode and Cathode of LED. Because of this they can be used whether at explosion danger places, or at chemical industry without special bell-glass or armature which will reduce an investment costs too. Technology applied during manufacturing light sources, listed patents, our team's professional knowledge who participate in development assure together that lamps offer a long lifetime, economical and safe solution for possible lighting technology tasks. LED lamps soon will become leader alternative of lighting technology in consequence of their listed additional cost reducing effects and wide range of use. In case of budgetary institutions it means another advantage that lighting modernization's costs can be accounted for as an investment. However they have to raise funds for paying costs of operation and upkeep. LED lighting is at an advantage in this case too, because its low consumption. Savings will appear IMMEDIATELY during newly installed light sources operation, since you can realize the difference in the next month's ligth bill.
