Features

  • colored, clear package
  • plasic package with a special design
  • in connection with an additional, custom built reflector suitable for backlighting of display panels
  • for optical coupling into light pipes
  • uniform illumination of a diffuser screen in front of the custom built reflector
  • solder leads with stand-off
  • available taped on reel
  • load dump resistant acc. to DIN 40839
  • Note: If the diffuser screen is tinted, the spectral transmission must be adjusted to the wavelength emitted by the LED.
