Achieving High CRI Lighting with High Efficacy Using Luminus LUX Technology

Luminus_LUX_KSF_phosphor_white_paper

Luminus has recently announced the availability of the LUX Series COB LEDs using innovative new
narrow band red phosphor (KSF) technology. These new COBs have been developed to achieve high
color quality with improved energy efficiency. They are available with both 90 and 95 CRI
minimums and LES sizes from 4 mm to 22 mm in a variety of flux densities and with a full range of
CCT: 2400K, 2700K, 3000K, 3500K, 4000K, 5000K and 6500K.

The 90 CRI minimum LUX series offers high-quality lighting with lumen/Watt efficacy that is
comparable to traditional 80 CRI sources. This allows luminaire makers to simplify their Bill of
Materials (BOM) by replacing commonly used 80 CRI products with 90 and 95 CRI products. By doing
so, they can achieve superior color rendition while maintaining the same level of efficacy. The LUX
series provides exceptional performance and quality of light, making it suitable for a wide range of
lighting applications including retail, residential, hospitality, architectural, museum, as well as in
downlights, track lights, and spotlights.

This white paper introduces KSF phosphor and discusses its characteristics, advantages, and
application in white LEDs. Topics covered include a performance comparison of KSF phosphor LEDs
versus traditional nitride-based white LEDs, how KSF phosphor LEDs provide industry-leading CRI
and TM30 performance, and the specific performance features of Luminus LUX COB KSF phosphor
LEDs. Information on various testing parameters is also provided, along with guidance on issues such
as pulse-width effects and color-shift effects that engineers will want to consider when designing
with KSF phosphor white LEDs.
