Abstract
Official abstract text for this publication.
Disclosed herein are low pressure discharge lamps having enhanced chroma and color preference. improved color quality scale, especially at elevated color temperatures, is provided. The light generated by the light-emitting elements of the lamp, when the lamp is energized, has Color Preference Scale values, as well as delta chroma values for fifteen color samples of the Color Quality Scale, within select parameters.
First claim
Opening claim text (preview).
What is claimed as new and desired to be protected by Letters Patent of the United States is: 1. A low pressure discharge lamp having evenly enhanced chroma and improved color preference, which lamp when energized has a total light emission exhibiting a correlated color temperature (CCT) of between about 2000 kelvin to about 4500 kelvin, the lamp comprising: a light-transmissive envelope, a fill gas sealed inside said envelope, and a phosphor composition having a light emissio…
