Abstract (en)
[origin: WO2011126473A1] An RF screen for microwave powered UV lamp systems is provided. The RF screen is formed of a single sheet of conductive material in which a mesh pattern has been formed. The screen includes a non-traditional mesh pattern including individual openings with 3 or more nodes. The RF screen is generally configured to optimize the balance between light transmission and RF energy leakage desired for the particular application. Generally, it is desired that the RF screen has an open area percentage greater than about 80% while limiting RF energy leakage from the microwave powered lamp system to acceptable levels.
