Abstract

A wall-installed lighting equipment comprising at least one light source (A), which is able to provide a light scattering, said light source (A) is positioned on a perimeter length (10) of a reflector (11) of the lighting equipment; in order to make the most of the direct light of the light source (A) and to make the most of the light that is reflected from the reflector (11) and in order to distribute the light in an efficient way along the exit routes, the lighting equipment, which is used for safety or emergency lighting, has a reflector (11) with a composite surface, whose profile consists of a broken line which includes vertical lines (S) and diagonal lines (T), said diagonal lines (T) joining the vertical lines (S) and having an inclination of between -20° and 60°, with respect to the perimeter length (10) on which the light source (A) is positioned.
