Phosphor Device and Illumination System for Converting a First Waveband Light into a Third Waveband Light Which Is Separated into at Least Two Color Lights and Projection Apparatus with the Same (as Amended)

Delta Electronics, Inc.

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 7 of these applications claim priority to application 61/537,687, filed Sep 22, 2011. A shared origin can cover several different claimed inventions, which is why members here may not share a title. In-force patents first, soonest term end first, then patent number. Expired patents follow, in the same order.
