Abstract
A light-emitting apparatus, such as a sun-tanning apparatus, has a housing enclosing a light source and other components, and a wall made of a translucent material through which light and other radiation passes to a user. The wall has a first surface facing the light source, and a second surface facing away from the source. To provide light scattering, so that a user does not see the image of the light source or non-light-emitting components, at least one of the surfaces, preferably the first surface only, has a surface structure divided into at least two areas which scatter light while still radiating a sparkling light. Each of these areas has a mutually different surface structure, preferably formed of a respective pattern of elementary structural shapes.
