Title (EN) ILLUMINATION DEVICE
(FR) DISPOSITIF D’ÉCLAIRAGE
(DE) VORRICHTUNG ZUM BELEUCHTEN
Abstract:
(EN) The invention relates to an illumination device having a light source (1) for emitting light in a spectral range of the visible light spectrum, and a retroreflector (2) connected mechanically to said light source (1). The retroreflector (2) comprises optical elements (22) with a refractive index of at least 1.6 and has a retroreflection coefficient (RA) of at least 10 cd/(lx m²) in the spectral range.
(FR) L’invention concerne un dispositif d’éclairage présentant une source lumineuse (1) pour émettre de la lumière sur une plage spectrale correspondant au spectre de la lumière visible, et un rétroréflecteur (2) relié mécaniquement à la source lumineuse (1). Le rétroréflecteur (2) présente des éléments optiques (22) ayant un indice de réfraction d’au moins 1,6 et présente un coefficient de rétroréflexion (RA) d’au moins 10 cd/(lx m²) sur la plage spectrale.
(DE) Eine Beleuchtungsvorrichtung weist eine Lichtquelle (1) zum Aussenden von Licht in einem Spektralbereich des sichtbaren Lichtspektrums, und einen mit der Lichtquelle (1) mechanisch verbundenen Retroreflektor (2) auf. Der Retroreflektor (2) weist optische Elemente (22) mit einem Brechungsindex von zumindest 1,6 auf und hat einen Retroreflexionskoeffizienten (RA) von zumindest 10 cd/(lx m²) in dem Spektralbereich.
