LED systems TALEXX

FAQ: Frequently asked questions


  1. What is the IP rating of Tridonic LED modules and LED converters?
    • LED modules for installation do not have an IP rating, unless otherwise indicated (e.g. TALEXXchain P511 IP67 CRYSTAL). IP protection must be provided by the luminaire. The IP rating of the TALEXXengines is specified in the relevant data sheets. Unless otherwise indicated, TALEXXconverters have an IP20 rating.
  2. Can I switch my LED modules on the secondary side of the converter?
    • No, only primary-side switching is permitted.
  3. Do LED modules need cooling?
    • For LED modules for which additional cooling is required the recommended heat sink area and Rth value are given in the data sheet. The specified heat sink may differ depending on the installed location. The maximum tc temperature must not be exceeded.
  4. What standards apply to LED products?
    • The relevant standards are listed in the relevant data sheets. Generally these are EN 62031 and EN 62471.
  5. Storage conditions for LED products
    • TALEXX modules should ideally be stored in their as-delivered condition in their original packaging or in a dark place.

      Permissible storage temperature range: -25 °C to +80 °C
      Permissible storage humidity range: 0–80 %

  6. Does “protective coating” means that the product is watertight/waterproof?
    • No.

      The LED modules are provided with a protective coating which protects against surface moiture (to JEDEC JESD22 A100C) and high relative humidity. If the protective coating is damaged (e.g. by soldering) it must be subsequently restored.

  7. What do you need to know if LED modules are encapsulated?
    • Encapsulation of LED modules is not permitted.
  8. Is ESD protection needed when working with LED modules?
    • Yes. TALEXX products are electronic components and as such are sensitive to electrostatic discharge.

      To avoid ESD damage, the modules must be handled, packed and stored in an ESD protected environment.

  9. What effect does the ambient temperature have on the forward voltage of LED modules?
    • The forward voltage is dependent on the ambient temperature, among other things. The forward voltage is higher at low temperatures.
  10. What effect does the ambient temperature have on the luminous flux of LED modules?
    • The better the thermal management of the LED, the higher the luminous flux.
  11. What standard system is used for the colour location/colour tolerances?
    • The CIE1964 colour system is used for all current products.
  12. How much UV/IR radiation is in the light emitted by TALEXX LEDs?
    • The light spectrum emitted by TALEXX LEDs contains no UV or IR components.
  13. Does the laser classification also apply to LEDs?
    • No, the “laser standard” does not apply to TALEXX LEDs. EN 62471 applies instead.
  14. What is the Ra, Rff colour rendering index?
    • The colour rendering index (Ra) is specified in the relevant data sheets. Rff is a special colour rendering index for illuminating meat and meat products.
