.cndot. A lighting device comprises an illumination assembly and a diffuser assembly. The illumination assembly has a casing, a light source, and a magnetic element. The diffuser assembly has a planar translucent light diffuser, a mirror coating and a magnetic element. The light source of the illumination assembly is capable of generating downwardly directed light for a narrow angle of illumination. The translucent light diffuser of the diffuser assembly is capable of diffusing light for a wide angle of illumination. The mirror coating is capable of preventing light leakage from the translucent light diffuser by internal reflection. The diffuser assembly is capable of magnetically attaching to the illumination assembly. The diffuser assembly is capable of detaching from the illumination assembly when force is applied. This invention relates to lighting systems with light diffusers, and the principal use of the invention is for providing both task light illumination and room lighting.
Un appareil d'éclairage comprend un ensemble d'éclairement et un ensemble diffuseur. L'ensemble d'éclairement comprend un boîtier, une source lumineuse et un élément magnétique. L'ensemble diffuseur comprend un diffuseur translucide planaire, une couche spéculaire et un élément magnétique. La source lumineuse de l'ensemble d'éclairement peut générer de la lumière orientée vers le bas dans un angle d'éclairement fermé. Le diffuseur translucide planaire de l'ensemble diffuseur peut diffuser la lumière dans un angle d'éclairement ouvert. La couche spéculaire prévient la perte de lumière dans le diffuseur translucide par réflexion interne. L'ensemble diffuseur se fixe magnétiquement à l'ensemble d'éclairement. L'ensemble diffuseur peut se détacher de l'ensemble d'éclairement lorsqu'une force est exercée. Cette invention concerne les systèmes d'éclairage munis de diffuseurs, et elle sert principalement à procurer de l'éclairement pour une tâche à effectuer et de l'éclairage pour la pièce.
