Flat-panel display device, illumination system and radiation source suitable for use in such a flat-panel display device.

摘要

The invention relates to a flat-panel display device (1). The display device (1) comprises a support (3) on which a plate-shaped waveguide (7) is arranged which is irradiated by a radiation source (15) at at least one end face (25). The radiation source (15) is arranged in a lighthousing (13), a first part (17) of which is an integral part of the support (3) and a second part (19) is detachable so that the radiation source (15) can be replaced. The lighthousing (13) further accommodates a reflector (29) for reflecting radiation emitted by the radiation source (15) towards the waveguide (7). The lighthousing (13) with the radiation source (15) and the waveguide (7) jointly constitute the illumination system (5) for illuminating a transmission display panel (11) arranged on the waveguide (7). The radiation source (15) is provided with lampholders (31) which, upon connection of the radiation source (15) in the lighthousing (13), cooperate with recesses provided in the lighthousing so that the radiation source (15) is positioned free with respect to the reflector (29) and at a distance d from the waveguide (7).
