Lexedis unveils high-CRI powerXED emitter
Lexedis Lighting has developed a tri-band phosphor that enables Ra of 90 in warm white, with good rendering of red colors.
The warm-white version of the device has a color rendering index (Ra) of up to 90, thanks to the use of a tri-band phosphor. Lexedis has branded this as indeXED 90.
The powerXED is available in four standard correlated color temperatures (CCT) of 3000 K, 4200 K, 5700 K and 6500 K. The product takes advantage of Zero Colour Binning developed by Lexedis; the company says this ensures that, at any value of CCT, there is no discernable difference in color temperature and color rendition between different LEDs.
The package has a very small form-factor, measuring 2.5 mm x 2.5 mm x 0.6 mm, the same as the company's nanoXED emitter. The chip-in-silicon packaging with good thermal properties, and the use of all-inorganic materials ensures durability, reliability and a long service life in excess of 50,000 hours. The powerXED has a 120° Lambert beam pattern.
The device’s high Ra is expected to fulfill the requirements of architects, lighting designers and lighting engineers for high-performance light sources by exceeding the Ra of 70-80 prevalent in fluorescent lighting
The high-CRI powerXED emits a quality of natural light which makes it a suitable choice for application in retail, medical and dental lighting as well as both linear architectural and façade lighting applications.
