Abstract
A solid state illumination system is disclosed, wherein a light source module comprises a first light source, comprising an LED and a phosphor layer, the LED emitting a wavelength λin an absorption band of the phosphor layer for generating longer wavelength broadband light emission from the phosphor, Δλ, and a second light source comprising a laser emitting a wavelength λin the absorption band of the phosphor layer. While operating the LED, concurrent laser pumping of the phosphor layer increases the light emission of the phosphor, and provides high brightness emission, e.g. in green, yellow or amber spectral regions. Additional modules, which provide emission at other wavelengths, e.g. in the UV and near UV spectral bands, together with dichroic beam-splitters/combiners allow for an efficient, compact, high-brightness illumination system, suitable for fluorescence imaging and analysis.
