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
- Deep Color for illuminated parts
- Pre-Drying Conditions
- 120 °C in a dry air (dessiccant) dryer for 2-4 h
- 120 °C in an air circulating dryer for 4-12 h
Storage & Handling
- Storage Conditions
Store in dry, protected from light.
