Description

  The present invention relates to a lighting fixture.

  Conventionally, the lighting fixture provided with the shade and panel which covers a light source part is well-known. With the shade or the panel, the illumination light from the light source unit can be diffused to reduce glare, and at the same time, a decorative effect can be obtained by the diffused illumination light.

  Patent Document 1 discloses a lighting fixture in which a diffraction grating is applied to the surface of colorless or colored glass to give a decorative effect. However, the shade of the lighting fixture disclosed in Patent Document 1 is provided with a diffraction grating on the surface of a single glass to diffract the irradiation light into a spectrum to obtain a decorative effect.

  On the other hand, a lighting fixture having a doubled shade is also known. Patent Document 2 discloses a lighting fixture in which a shade is doubled with a translucent member and a translucent member. In the luminaire described in Patent Document 2, even if insects and dust accumulate on the translucent member disposed near the light source unit, the translucent member is separated from the translucent member, so that light from the light source unit wraps around. As a result, the shadows of insects and dust are diluted, and the shadows of the translucent member are less noticeable. Further, the closer to the center of the luminaire, the greater the distance between the translucent member and the translucent member, and the shadow of insects and dust is diminished. However, the lighting apparatus of Patent Document 1 is a technique for making shadows of insects and dust inconspicuous, and does not aim at a decorative effect by diffused irradiation light. Further, since the distance between the translucent member and the translucent member is not constant, the appearance of the irradiated light is different between the vicinity of the center and the peripheral portion.

  According to a third aspect, the first light transmissive member includes a planar third light transmissive surface disposed at a position close to the light source unit, and the second light transmissive member includes the first light transmissive member. Since the flat fourth light-transmitting surface disposed substantially parallel to the one light-transmitting member is provided, a large number of transmitted light diffused by the first light-transmitting member and the second light-transmitting member is flat. It appears on the surface of the shaped second light transmitting member, and a decorative effect by the diffused transmitted light can be obtained.
