LIGHTING DEVICE WITH LIGHT SOURCE AND WAVELENGTH CONVERTING ELEMENT |
摘要 |
<p>The invention relates to a lighting (1) device comprising a light source (2) and a wavelength converting element (7), which comprises a phosphor compounded with a polymer. The phosphor contains a metal-ion activator which is excitable via a partially forbidden electronic transition. The phosphor and the polymer being chosen such that the difference in their refractive index is smaller than 0.1. Due to this choice, scattering in the wavelength converting element (7) remains at minimum. Interesting wavelength converting elements (7) are obtained when using phosphors comprising specific Mn(IV)-activated fluoride compounds and specific fluorine-containing polymers.</p> |
