PureSpectrum, Inc. (PSPM.PK) Announces Two New Issued Patents Related to Lighting Technology
PureSpectrum announced that two new patents have been added to its family of patents related to ballast technology that improves the performance of ballast-driven lighting applications. PureSpectrum Technology targets performance areas which have been identified as consumer acceptance barriers such as light quality and start time for fluorescent bulbs, and the recently issued patents represent some of the earliest engineering that was done to improve light output and energy efficiency. Patent 7,235,932 represents an important breakthrough in ballast circuitry which allows DC current to generate a more efficient square wave rather than the less efficient sine wave configuration found in…
