Technical Details & Test Data

Product Performance Characteristics

Alcom® LDDC – Deep Color
 

• Deep Color for illuminated parts
  • Optical appearance in deep colors (e.g. “Piano Black”) when backlight LEDs switched off
• Optimized transmission of (colored) LED light
  • Symbols or displays visible, when LEDs are switched on
  • No visual color shift of transmitted light
• Transmission with/without homogeneous scattering
  • Tailor made: Color, transmission, haze, half power angle
• Suited for illuminated applications
  • Seamless user interfaces
  • Decorative elements, consoles
• Displays, touch sensitive surfaces

​​​​​​​

Example: Cover Lens for Displays

• Transparent black material covers display unit
• Mold-in-Color user surface
• Display on: clear transmission
• Display off: deep gloss black panel
• Electronics not visible

Example: Classic Ambient Lighting
 

• Piano black diffusing lens
  • Homogeneous light output
• Established assembly concepts
• Can be implemented into seamless designs

Also, for ambient lighting of larger areas, e.g.

• Illuminated door trim
• Illumination of center console

​​​​​​

Pre-Drying Conditions

• 80 °C in a dry air (dessiccant) dryer for 3-4 h
• 80 °C in an air circulating dryer for 4-6 h

Storage & Handling

Storage Conditions
