Highest colour rendering in smallest LED emitters for high-end directional lighting

June 06, 2013 // By Graham Prophet
‘Gallery White’ CRI 97 emitters achieve higher levels of light quality, intensity and consistency in highly demanding retail, gallery and showroom applications.

LED Engin's compact ‘Gallery White’ emitter for directional lighting claims an exceptional colour rendering index (CRI) of 97. Designed for high-end applications, including retail outlets, galleries and museums where accurate colour representation is vital, Gallery White offers high colour fidelity in warm white light (3000K) and achieves impressive individual R values (R1-R15) to enhance the contrast of retail merchandise, artwork and skin tones. Colour temperature and CRI remain stable over time, temperature and drive current.

Gallery White emitters feature outstanding colour consistency with an option for customers to specify a 3 SDCM (Standard Deviation of Colour Matching) bin. Accurate colour rendering is a critical factor in achieving the desired ambience in high-performance applications. While the CRI measures the light source against 8 pastel pigment colours (R1-R8), it does not take into account saturated solids (R9-R12) or skin tones (R13 and R15). Not only does Gallery White achieve a CRI of 97, the emitter also delivers outstanding R1 to R15 values between 96 and 99 and R12 typically of 86.

LED Engin offers Gallery White emitters in a range of package sizes for different power ratings from 10W to 80W, delivering between 450 and 3200 lumens output. The emitters are based on LED Engin’s LuxiGen platform that is up to eight times smaller than array-based solutions with the same flux performance. LuxiGen thermal packaging design allows LED dice to be driven to higher current levels, while keeping junction temperatures low, ensuring long operating life and superior colour point stability (>50,000 hours).

The tiny emitters work with total internal reflection (TIR) lenses to produce smooth, glare-free beam profiles from very compact fixtures while delivering 30% more Lux-on-Target than other high-CRI competing products. A suite of complementary TIR lenses is available to enable fixtures with beam widths from 9 degrees to 50 degrees.
