Samsung Introduces Colour-optimised Chip-on-Board LEDs

News

New colour packages are engineered to bring out the most desirable colour tones of illuminated objects (see picture on the right)

Samsung Electronics has announced a new family of chip-on-board LED lighting packages, called the 'Samsung D-series Special Color'. The packages are engineered to bring out the most desirable colour tones of objects whose viewing is particularly colour-sensitive, making them optimal for many commercial lighting applications.

Through spectrum engineering, colour spectrums within the D-series have been tuned to deliver high colour vividness, without the use of harmful ultraviolet (UV) lighting chips. The packages deliver a TM-30 Gamut Index (Rg) of over 110, a level that ensures lighting with outstanding colour and whiteness.

Today, to provide almost as vivid colour, 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 colours, 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 nearly as long.

As colour 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. To determine the most attractive colour 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," said Jacob Tarn, executive vice president of the LED Business Team at Samsung Electronics. “We are determined to continue to be the leading innovator in LED component solutions that are not only outstanding in quality, but which also bring the most practical benefits to the ultimate user – consumers."

Packages generate from 13 to 33 watts to create 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.
