摘要： Proposed is an illumination device (100), comprising a light source (110) such as an LED or a laser diode, a wavelength conversion medium (120) such as a phosphor, and a periodic antenna array (300) made of a highly polarisable material such as a metal. The light source emits primary wavelength light that at least partially is converted in secondary wavelength light by the wavelength conversion medium. The periodic antenna array is positioned in close proximity to the wavelength conversion medium and functions to enhance the efficiency of the absorption and/or emission processes in the wavelength conversion medium through the coupling of the incident primary wavelength light or the emitted secondary light to surface lattice resonances that arise from the diffractive coupling of localized surface plasmon polaritons in the individual antennas of the array. This is especially advantageous for forming low étendue illumination device suitable for use in projection systems, or for controlling the directionality, the polarization, and/or the color of the secondary wavelength light.
