    摘要： A planar illumination device (1) according to an embodiment comprises: a substrate (2); a first linear Fresnel lens (5, 5a); and a second linear Fresnel lens (5, 5b). A plurality of light sources (3) are disposed two-dimensionally in a grid pattern on the substrate (2). The first linear Fresnel lens (5, 5a) is disposed on the emission side of the plurality of light sources (3), and a groove (5c) that constitutes a concave-convex surface of the lens extends in one direction. The second linear Fresnel lens (5, 5b) is disposed on the emission side of the first linear Fresnel lens (5, 5a), and a groove (5d) that constitutes a concave-convex surface of the lens extends in a direction orthogonal to the one direction.

    摘要： The present invention relates to an emergency luminaire, provided with a casing through which it is attached to the ceiling or wall, exhibiting a diffuser (D) with a smooth (flat or curved) outer surface (SEx) and an inner surface on which lenses (L) defined by microstructures (Ms) have been shaped that have been calculated by means of an algorithm that determines the configuration of a plurality of sawtooth cuts, with a constant period or peak-to-valley distance from the outside to the centre on the horizontal axis (Dx), the longest edge of which makes up the active face (as0, as1, etc.) thereof, facing the LED, and the opening angle (Alfap0) of the successive sawtooth edges (as0, as1, etc.) increases progressively towards the centre of the lens, so that each ray of light of the output beam through said lenses is adjusted in the desired direction according to the light projection of the application.

    摘要： An object of the present invention is to provide a novel lighting device in which a lighting equipment lens itself serves as a virtual light emitting portion and the lighting equipment lens itself swings like a balancing toy.
    In order to solve the problem described above, provided is a lighting device including:
    a lighting equipment lens unit; and
    a stand member on which the lighting equipment lens unit is placed,
    wherein the lighting equipment lens unit includes a lighting equipment lens in which a protruding portion capable of point-supporting the entire lighting equipment lens unit is formed,
    a center of gravity of the lighting equipment lens unit is located substantially coaxially with the protruding portion and below the protruding portion,
    the stand member includes:
    a housing having an opening; and
    a light transmitting placement portion that is placed in the housing and allows placement of the protruding portion,
    the stand member allows irradiation of light toward the opening through the light transmitting placement portion, and
    a surface of the light transmitting placement portion on which the protruding portion is placed is formed into a concave shape.
