TL;DR: In this article, a rigidity-reinforced streetlight which can suppress bending deformation by reinforcing the rigidity of the streetlight is presented, where the ribs pass through a light pillar in a direction crossing an axial direction of the light pillar to be welded.
Abstract: The present invention relates to a rigidity-reinforced streetlight which can suppress bending deformation by reinforcing the rigidity of the streetlight. The rigidity-reinforced streetlight comprises: a flange installed on the ground; a light pillar which is vertically erected to the flange and is hollow inside; a luminaire installed on one side of the light pillar; and ribs installed at regular intervals along the inside of the light pillar and reinforcing the rigidity of the light pillar to suppress bending deformation of the light pillar. The ribs pass through the light pillar in a direction crossing an axial direction of the light pillar to be welded.

TL;DR: In this article, the X-Rite MA68 II multi-angle spectrophotometer was used to measure the spectral energies of the matte light pillar holographic materials, and the reflective and diffractive spectral energies perpendicular to the direction of the light pillar and along the direction along the light column in the visible light range at five angles (15°, 25°, 45°, 75°, 110°) were analyzed with the grating equation.
Abstract: In order to study the grating constant of the matte light pillar holographic materials, the X-Rite MA68 II multi-angle spectrophotometer was used to measure the spectral energies of the matte light pillar holographic materials. The reflective and diffractive spectral energies perpendicular to the direction of the light pillar and along the direction of the light pillar in the visible light range at five angles (15°, 25°, 45°, 75°, 110°) were analyzed with the grating equation. It was found that the grating constant of the matte light pillar holographic materials is in a range rather than that of the rainbow light pillar holographic materials which had fixed value, which will only cause the lightness variations significantly.
