Abstract

Eine Leuchte mit mindestens einer langgestreckten Leuchtstofflampe (28) weist einen ebenfalls langgestreckten, im Profil wannenförmigen, verstellbaren Reflektor (10) auf, dessen längsverlaufende Mittelebene (12) die Längsachse (26) der Leuchtstofflampe enthält. Das Profil des Reflektors (10) ist veränderlich. Wenigstens an einem Längsende des Reflektors (10) sind Stelleinrichtungen (34,36) zur Lageveränderung je eines freien Längsrandes (32) des Reflektors (10) vorgesehen. Die Lageveränderung erzwingt jeweils eine Profilveränderung des Reflektors (10).

Figure 00000001
A luminaire with at least one elongated fluorescent lamp (28) has an likewise elongated, trough-shaped, adjustable reflector (10), the longitudinal central plane (12) of which contains the longitudinal axis (26) of the fluorescent lamp. The profile of the reflector (10) is variable. At least at one longitudinal end of the reflector (10), adjusting devices (34, 36) are provided for changing the position of a free longitudinal edge (32) of the reflector (10). The change in position forces a change in the profile of the reflector (10).
