WAVELENGTH CONVERSION BOARD AND ILLUMINATION DEVICE COMPRISING THE SAME

摘要

The present invention provides a wavelength conversion board comprising a substrate; one or more fluorescence members each containing a fluorescence substance for converting excitation light into fluorescence, the fluorescence member being disposed on or above the substrate; and a flexible gel disposed around the fluorescence member. The present invention also provides a wavelength conversion board comprising a substrate; a fluorescence member containing fluorescence substance for converting excitation light into fluorescence, the fluorescence member being disposed on or above the substrate; a fluent material disposed around the fluorescence member; a light-transmissive plate parallel to the substrate; and a sealing member disposed around the fluent material in a cross section of the wavelength conversion board. The fluorescence member is interposed between the light-transmissive plate and the substrate in the cross section of the wavelength conversion board.
