Abstract (en)
[origin: EP0386795A2] A lightstand is proposed which comprises a hollow body (1), on the floor (2) and side faces (3) of which a reflecting layer is applied on the inside and in which a fluorescent tube is disposed as a light source (4) and the light exit aperture is provided with a diffusing surface (5). It is proposed that a partially transparent, partially reflective layer (6) be disposed in the light propagation direction in front of the diffusing surface (5), the transparency of which increases proportionally with the increase in the distance from the light source (4) to provide even illumination of the light exit aperture. <IMAGE>
