A blocking structure is used to block a direct view of the beam of light when the fixture is installed such that only indirect light is primarily visible from a viewer at least in or around a working plane substantially parallel to the ceiling.

  • Patent number: 8882299
    Abstract: Disclosed is a wavelength conversion member that is provided with: a light transmissive member including a light input plane into which excitation light is inputted, and a light output plane from which wavelength converted light is outputted; and a semiconductor fine particle phosphor, which is dispersed in the light transmissive member, and which absorbs the excitation light, converts the wavelength, and emits light. The dispersion concentration of the semiconductor fine particle phosphor in the direction parallel to the light traveling direction, i.e., the direction connecting the light input plane and the light output plane, is lower than the dispersion concentration of the semiconductor fine particle phosphor in the direction orthogonal to the light traveling direction.

    Abstract: A cover, in particular for an explosion-proof luminaire at least comprises a mounting frame, which is detachably fastened to the luminaire, and a transparent luminaire cover held at least along a circumferential edge by the mounting frame. In order to improve a cover of this nature to the effect that it is protected in a cost-effective manner and without substantial constructive effort from the occurrence of microcracks due to the effects of shocks and impacts on the luminaire cover, a transparent protective cover is placed in front of the luminaire cover for a flameproof and impact-resistant embodiment of the cover. The invention also relates to an explosion-proof luminaire with a cover of this nature.

    Abstract: The invention relates to an illumination system (10), a luminaire (102), a collimator (30), and a display device (200). The illumination system according to the invention comprises a light source (20) and the collimator. The light source is configured to emit a substantially Lambertian light distribution around an axis of symmetry (22). The refractive collimator is configured to redirect light from the light source so as to at least partially illuminate an illuminating surface (50), in which at least a part of the illuminating surface is substantially parallel to the axis of symmetry. The refractive collimator comprises a concave entrance window (34) and an at least partially convex exit window (40) for refracting light towards the illuminating surface. The illumination system according to the invention has the effect that a height of the illumination system may be reduced by virtue of the use of the refractive collimator.
