    Abstract: An apparatus including a retro-reflective section. The retro-reflective section includes an outer surface, an inner surface, and a plurality of retro-reflective microelement. One or more of the plurality of retro-reflective microelements include a plurality of reflective surfaces. Each of the plurality of retro-reflective microelements extends from the inner surface at a location different from locations of the other retro-reflective microelements, and each of the plurality of retro-reflective microelements comprises a central axis extending along a direction that corresponds to a surface normal of the outer surface.

    Abstract: An image display device includes an image-forming element and a light source. The image-forming element includes a base member including a first surface, and a reflector array on the base member. The reflector array includes multiple reflector rows, each including multiple dihedral orthogonal reflectors along a first direction. Each of the multiple dihedral orthogonal reflectors includes a first reflecting surface reflecting light from the first surface side, and a second reflecting surface that is orthogonal to the first reflecting surface and reflects a reflected light from the first reflecting surface toward the first surface side.

    Abstract: An image display device includes an imaging element and multiple light sources. The imaging element reflects light of the multiple light sources and forms multiple floating images in mid-air. The imaging element includes a base member including a first surface, and a reflector array on the base member. The reflector array includes multiple reflector rows including multiple dihedral corner reflectors along a first direction. The multiple reflector rows are arranged parallel to a second direction crossing the first direction. The multiple dihedral corner reflectors each include a first reflecting surface, and a second reflecting surface orthogonal to the first reflecting surface.

    Abstract: Provided is a retroreflective structure and a light-emitting safety band using same. The retroreflective structure comprises: a switch unit for supplying power, a light source being connected to the switch unit; and a light-emitting unit coupled to the switch unit. The switch unit comprises: a middle plate case having a light transfer body insertion hole formed thereon; an upper plate case coupled to the upper portion of the middle plate case; and a PCB inserted into the middle plate case and the upper plate case. The light-emitting unit comprises: a lower retroreflective film; and a light transfer body installed to be forced against the upper portion of the retroreflective film. The light source is inserted into and installed in a light source insertion groove on an end of the light transfer body having a case engaging unit installed to engage with the light transfer body insertion hole.

    Abstract: Display apparatus includes LEDs, bottom chassis to accommodate the LEDs; and reflective member disposed on the bottom chassis. The reflective member includes a reflective bottom portion, and a reflective inclined portion obliquely formed to face a rear surface of the display panel which includes first regions that respectively correspond to LEDs located adjacent to the reflective inclined portion, and second regions each provided between two neighboring first regions and has a reflective characteristic different from a reflective characteristic of a neighboring first region. Second regions and neighboring first regions are on the reflective inclined portion having a uniform incline angle with respect to a side edge of the reflective bottom portion, the first regions include a group of light adjusting members, and the group of light adjusting members of each of the first regions is disposed to correspond to one of the LEDs disposed adjacent to the reflective inclined portion.
