WAVELENGTH CONVERTING SCREEN FOR A LIGHTING DEVICE

摘要

A screen for a lighting device and a method of manufacturing such a screen are provided. The screen is adapted to receive and transmit light from a light source. The screen comprises two at least partly transparent sheets opposing each other, and a structure(40) arranged between the two sheets. The structure provides a plurality of compartments (400) having sidewalls (430) extending from one of the sheets to the other sheet. Further, at least one of the compartments encapsulates fluid (440) and wavelength converting particles (450). The present invention is advantageous in that wavelength converting characteristics can be made regular across the screen while the screen can be arbitrary mounted in any orientation without the wavelength converting characteristics being affected by gravity.
