The StringLED is a string (chain) of LEDs in a form of LED modules interconnected with flexible conductor – its main applications are the channel-type highlighted letters, block letters or with halo effect. The system is resistant to mechanical damage as we know what harsh conditions exist during installation. It is also resistant to weather conditions due to polycarbonate shield and encapsulation by means of over-moulding technology. Servicing the channel type letters is of extreme difficulty, hence the reliability is the most important advantage of our product. Our system operates without a power supply unit. Expected free-of-trouble period amounts to 15 years of operation, 10 hours a day.

      StringLED units can be put into illuminated (backlit) letters independently, while observing the rule that the distance between LEDs must not be longer than the distance of a LED from the letter face. It would be easier, less expensive and faster when you send us the drawing of ad and we design the optimum distribution of LEDs within the ad unit (ensuring the lowest cost of LEDs and of mounting operation). The design is free of charge when the customer uses our StringLEDs to highlight the letters. The letters would shine brightly and evenly.
      Depending on the base of letters, the LEDs can be secured in various ways. When letter base is made out of foamed PVC, we recommend upholstery staples. For the base of sheet metal or hard plastic, recommended is thermosetting adhesive or double-sided adhesive tape.
      The StringLEDs are manufactured in two supply versions: power supply 12V, where you must use a power supply to reduce voltage from 230V to 12V, and version supplied directly from 230V mains. We recommend the latter solution as it is cheaper, energy-saving and reliable.
StringLED system to highlight block letters. Flexible, energy-saving and reliable LED system.
StringLEDs to highlight halo effect letters. Weather resistant.
      Power supply units, due to the elements used in their construction, are of relatively short lifetime and low efficiency (high energy loss).
      In this way, often a LED system, which inherent feature is low energy consumption, becomes no more energy-saving due to the power supply unit, and this fact is not revealed by the suppliers. Additional problem is related to installation of the power supply unit in illuminated letters. There is not always a sufficient space for it. The StringLED in 230V version has no power supply unit. It has just a small integrated module MPA protecting the system against harmful peaks up to 3.5 kV from the mains. Our power mains is not free from such disturbances. The MPA protects also against short-circuit, overload and excessive temperature rise – all to ensure that the system is reliable and durable.
      The StringLED 230V is fabricated in two lengths of LED strings: 30 LEDs and 60 LEDs. When you order us the design of LED arrangement in the letters, our designers will distribute LEDs so as their total number is divisible by 30.
