摘要： 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.

摘要： 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.

摘要： A system and method for utilizing corner-cube reflector technology for irradiation control in direct radiant heating systems is described. The system and method has application in many types of direct irradiation heating systems and is applicable to both narrowband or broadband directed irradiation heating systems. The purpose and result of the implementation is to improve the overall system efficiency through the redirection of photons back to a targeted item which is being heated or treated with the irradiation energy.

摘要： A retroreflective system is disclosed that includes a retroreflective sheet for retroreflecting light, and a light control film disposed on the retroreflective sheet. For a first wavelength, light incident on the light control film at each of a first and second angles of incidence is retroreflected. For a second wavelength, light incident on the light control film at the first, but not the second, angle of incidence is retroreflected.

摘要： 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.

摘要： The invention relates to an optical imaging system (100) and a device for floating display, and a surround-view display device (2000). The optical imaging system (100) sequentially defines, along the optical axis thereof, an object plane (10), a first image plane (101) and a second image plane (102), and the optical imaging system (100) comprises at least one imaging unit (110) arranged between the object plane (10) and the first image plane (101) on the optical axis, with the at least one imaging unit (110) having different light converging capabilities in a first direction and in a second direction, and the first direction and the second direction being orthogonal to the optical axis, respectively; and a main diffusion screen (120) diverging light in the second direction, the optical imaging system (100) being configured such that a light beam from a point on the object plane (10) forms a line image in the first direction on the first image plane (101), and the light beam from a point on the object plane (10) forms a line image in the second direction on the second image plane (102), with the second image plane (102) being a floating image plane.

摘要： This invention is a novel retroreflective traffic stripe comprising a widely spaced repeating pattern of linear light turning prisms over cube corner retroreflective prisms in a critical optimal configuration. The light turning prisms comprise at least two exposed surfaces, one approximately vertical facing the headlights of oncoming traffic, and another opposing the first and sloped by approximately 45 degrees. The approximately vertical surface efficiently accepts light from the headlights and transmits such light to the sloped surface which totally internally reflects such light downward onto an array of cube corner retroreflective prisms, which totally internally reflect such light in approximately the reverse direction. Such reflected light once more encounters the sloped face of the light turning prisms which totally internally reflects the light toward the approximately vertical surface, where such light exits and returns toward the headlights and, more importantly, toward the eyes of the driver of the vehicle.
