Abstract

The invention relates to a backlighting system (Bl) combining a low-pressure mercury vapor discharge lamp (Fl, F3) with a plurality of Light Emitting Diodes (LEDs) (Ll), in which system the light emitted by the LEDs is mixed inside the discharge vessel (V) of the low-pressure mercury vapor discharge lamp. In a preferred embodiment, the low- pressure mercury vapor discharge lamp comprises a diffuser coating with an aperture (Al, A3) through which the light emitted by the LEDs is admitted to the discharge vessel. In another preferred embodiment, the plurality of LEDs are side-emitting LEDs, the light being emitted predominantly in a direction parallel to a light exit window (EW) of the backlighting system. In a further preferred embodiment, the low-pressure mercury vapor discharge lamp provides a first and a second primary color, and the plurality of LEDs provide a third primary color such that the combination of the three primary colors provides an improved covering of the EBU color standard.
