CLAREX®
DR-IIIS DIFFUSION FILTER |
| CLAREX® DR-IIIS DIFFUSION FILTER
has been developed by the request of car audio manufacturers,
enabling the replacement of incandescent lamps with LEDs. |
 |
The LED
advantages include high brightness, lower electric consumption,
longer life, etc. DR-IIIS diffuser solves the 'too bright at night'
issue while providing excellent light uniformity. |
| • |
Available as thin as 0.5 mm, yet able to block up to
95% of light and provide effective diffusion |
| • |
Extremely uniform surface brightness |
| • |
Available in light transmissions ranging from 5% to
40% |
| • |
Available in thicknesses from 0.5mm to 1.0mm, in
0.1mm increments |
| • |
Available in any color |
|
|
|
BACKLIGHT CONSTRUCTION: |
|
Because of its high diffusion property, Clarex DR-IIIS can be positioned
directly above the LED, with a minimum gap, as shown below.
