The application provides a floor tile screen, comprising a box body (1), a rear body (2), a PCB board (3) and a front body (4), wherein the rear body (2) is fixed on the box body (1); the PCB (3) is arranged between the rear body (2) and the front body (4), and provided with lamp beads; a plurality of transparent fixing columns (41) are fixedly arranged on the front body (4), pass through the PCB board (3), fixedly connected with the rear body (2), and avoid the lamp beads. The fixing column (41) has the function of limiting the front body (4), the front body (4) and the rear body (2) are connected together by fixing columns (41), to avoid separation; the fixing columns (41) are transparent, so that the light emitted by the lamp beads is not blocked, the display effect of the floor tile screen is improved.

A protective device is installed about the outer edge or outer edges of a floor sign. When installed, the main body portion of the protective device is taller than the thickness of the sign such that an item being moved over the sign will ride on the top of the protective device as it passes over the floor sign. The protective device includes a tapered outer edge that helps an item to slide up onto the top surface of the protective device and decrease the impact force of the device when it initially encounter the protective device. The inner edge of the protective device is also tapered down to at least the height of the floor sign. The protective device is made from a hard material that is impact resistant and provides a smooth lower friction upper surface. The protective device can be installed with spaced ends to allow liquid to drain from inside the device.

Disclosed is a weather-resistant and crush-resistant display panel for placement on or in the surface of roadways, driveways, walkways, patios, or other locations and substrates. The panel is sealed within a polycarbonate enclosure with installed electro (electric/electronic) components that are protected by the set-up polycarbonate which cooperates with the enclosure and its installed components to become structurally reinforced. Light generated within or directed through the polycarbonate carries images/logos for displays, from these difficult roadways, driveways or walkways installation environments, for convenient and effective viewing by the public.

A cover device for gratings, having a planar support (1) and a plurality of holding elements (20) which protrude at a bottom side (7) of the support (1), wherein a plurality of elevations (10) and recesses (11) are provided on an upper side (6) of the support (1).

Display assemblies are provided. One or more electronic display subassemblies are mounted to a framework at an elevated position. An unobstructed zone is located below each of the electronic display subassemblies and within said framework. Wiring and electronic components may extend along some of the framework and may be covered by cladding.

A system for illuminating a carriageway in a case of fog includes a road safety barrier arranged along the carriageway, at least one fog density detecting device arranged along the road safety barrier, and a plurality of light sources borne by the road safety barrier, distributed along the road safety barrier, and oriented for each to emit a light beam having a direction that is transversal to an extension axis of the road safety barrier so as to illuminate signage on the carriageway. A control unit that is connected to the light sources and to the fog density detecting device is configured to activate the light sources when the fog density detecting device detects a fog density value of above a threshold value.
