Samsung introduces D-series Special Color chip-on-board LED packages optimized for color-sensitive commercial lighting

Samsung Electronics Co Ltd of Seoul, South Korea has launched the ‘D-series Special Color’ family of chip-on-board (CoB) LED lighting packages, which are engineered to bring out the most desirable color tones of objects whose viewing is particularly color-sensitive, making them optimal for many commercial lighting applications.

Through spectrum engineering, color spectra within the D-series have been tuned to deliver high color vividness, without the use of ultraviolet (UV) lighting chips. The packages deliver a TM-30 gamut index (Rg) of over 110, ensuring lighting with outstanding color and whiteness, says the firm. Currently, to provide almost as vivid color, many LED lamps instead use near-UV chips, which can damage the human eye and clothing after repeated exposure. Near-UV rays can display vivid colors, but only when the whites in the object being illuminated contain fluorescent brightening agents. An alternative is to use expensive ceramic discharge metal-halide (CDM) lamps that do not last as long.

As color has a significant influence on consumer purchase decisions, the new D-series now offers lighting options for three of the most important segments of commercial goods: fashion (stylish clothing), meat and vegetables. The LED packages for each segment have been designed with the most effective combination of phosphors to illuminate what is being sold in the most appealing way, claims the firm. To determine the most attractive color rendering and saturation levels based on subjective perceptions, Samsung ran extensive preference tests among many demographic groups worldwide.

“Our new D-series Special Color brings much greater value to the commercial lighting industry, reaching far beyond the ordinary image-rendering benefits of LEDs,” says Jacob Tarn, executive VP of the LED Business Team at Samsung Electronics.

The D-series Special Color has been in mass production since late October. Packages generate 13-33W to create what is reckoned to be the best combination of LEDs and phosphors for each commercial segment. Furthermore, they come in the same shapes and sizes as the standard Samsung D-series to simplify retrofitting of existing luminaires.
