Quality White Lighting with LEDs
Philips Lumileds is a leader in illumination grade white LED light sources. Quality, when used to describe white light from LEDs, refers to the consistence of color in the beam of light and correlated color temperature (CCT) variations over time and temperature and CCT variation between individual products. Philips Lumileds' advance packaging, materials and binning competencies coupled with our phosphor expertise and phosphor technology from Philips, one of the world’s leaders in phosphors, enable the production of LUXEON® power LEDs that deliver the quality of light required for commercial, residential and general lighting applications.
How are white LEDs created?
There are currently two ways to make white light with LEDs. One method mixes multiple wavelengths of different LEDs to make white light (i.e. RGB); allowing the lighting designer to tune the white light to a specific color temperature.
The second method uses a blue Indium-Gallium-Nitride (InGaN) LED with a phosphor coating to create white light. This is the method that results in the more commonly seen “white LED”.
Wide range of color temperatures
Philips Lumileds offers the full spectrum of white LED lighting from 2540K-10,000K. Our product offering of cool-white, neutral-white and warm-white LEDs enable lighting designers and specifiers to create lighting solutions with consistent color temperatures.
High Color Rendering Index (CRI)
Color Rendering Index or CRI is the calculated rendered color of an object. The higher the CRI (based upon a 0-100 scale), the more natural the colors appear. Natural outdoor light has a CRI of 100. White LUXEON® LEDs offer the industry's highest CRI, making objects to be illuminated appear more natural and vibrant.
Phosphor Deposition Techniques
LUXEON® LEDs use patented phosphor deposition systems which produce the best quality white light available. You can depend on LUXEON LEDs to deliver consistent white colors throughout the light beam making LUXEON® the best white light source available today.
