Remote phosphor – how it works The NDF advanced backlight technology is based on color conversion by remote phosphor. ARPHOS® uses a blue-pump LED as a basic light source. The advantage of this very stable blue LED is, that its wavelength can be converted to visible light in almost every color that you wish – we are able to customize the color to your specific needs. Furthermore, the stable phosphors are hardly stressed; lumen depreciation and color shift are therefore no issue! ARPHOS® technology is applicable in both direct lit and edge lit panels.
Direct lit Within this principle a limited intermediate cavity between the blue pump LED and the Remote Phosphor Film (RPF) works as a mixing chamber. The multiple function of the RPF converts the mixed blue light into white light and also works as a diffuser.
Edge lit A major advantage is that the edge lit principle does not need significant changes compared to existing edge lit systems. The light guide will bring the blue light homogeneously to the RPF which replaces the function of the diffuser and converts the blue light into white light.
Features and benefits 1. Highest efficiency 2. Limited lumen depreciation 3. High color consistency over lifetime 4. No LED binning issues 5. Customized colors
NDF Special Light Products B.V. was founded in May 1999 by management buy-out of two former employees of Philips Lighting. Gerrit van Amelsvoort and Coen van ‘t Westeinde started to produce custom-specified Cold Cathode Fluorescent Lamps for high-end LCD backlight applications in niche markets. In these past 17 years, we continued to MAKE LIGHT and innovate in both display technology and decorative lighting, which has resulted in a number of customized solutions for our customers.
To stay updated with regard to rules and regulations and everything that happens in the display and lighting industry, we are a member of various networking organizations, like SID (Society for Information Display), NAG (Netherlands Aerospace Group) and NLA (Dutch Lighting Organization).
In our immediate surroundings we have an eye for social contribution; we sponsor various local initiatives and organizations and we are member of several social networks.
We focus on quality; not only in our production unit, but also in our way of working. In 2014 NDF obtained the ISO 9001:2008 certification; a worldwide standard for quality!
