Evident nanophosphors used in LED holiday lights

Oct. 14, 2008
Nanocrystal semiconductor specialist Evident Technologies has announced a licensing agreement that will see a range of highly unusual LED colors in holiday lights.
Dotstrand lights Holiday Creations/Diogen Lighting, Inc. and Evident Technologies, Inc. have signed an exclusive licensing and purchase agreement to enable quantum-dot LEDs to be commercialized in the seasonal “light-strand” market in the US and Canada.

Evident’s technology uses semiconductor nanocrystals, also known as quantum dots, and will provide a range of “never-before-seen colors” (such as peach, lime and aqua) in holiday lights sold under the Dotstrand™ brand (see photo).

Traditional LEDs are energy efficient, but are fundamentally limited to a handful of colors like, red, blue, yellow and green. Phosphors can be used to alter the color, but the color pallet is still limited. Evident says that its quantum dot technology removes these limitations, and enables LEDs to “emit any color, including high quality white light.”

"As consumers become more aware of the energy savings afforded by LED lights, they are switching from the traditional incandescent lights. The problem with current LEDs is that their color selection is limited. Imagine if you only had five colors to choose from for painting, coloring or decorating," stated John Hayes, CEO, Holiday Creations/Diogen Lighting.

"This new technology gives us a wide range of colors for holiday and decorative lighting. We are excited to be able to offer these colorful new products to our customers for sale in retail stores beginning in 2009."

Clint Ballinger, CEO of Evident Technologies, said "We chose Holiday Creations as our partner for this technology because they are a progressive, forward-thinking, market leader with an established track record. We are eager to see their new line of light-strand products and the Dotstrand™ brand in US and Canadian retail stores."
