A lid to be connected to a housing of a status display for a sensor, with a basic body comprising a covering surface and at least one side wall, wherein the basic body has at least one light-transmissive light emitting region to facilitate an illumination of desired areas of the lid that is homogeneous and space-saving, with a first reflector unit and a second reflector unit arranged opposite each other, and wherein an opening for arranging a lighting means is formed in the second reflector unit, wherein the light emitted by the lighting means is reflected to the at least one light emitting region by means of the first reflector unit and the second reflector unit.

A visual signaling system includes smart signage with a set of three or more lights visible from a single direction. Activation of the lights in a first pattern indicates a hazard and for individuals to move away from the sign. Activation of the lights in a second pattern indicates safety and for individuals to move toward the sign. Activation of the lights in a third pattern indicates a need for caution and for individuals to refrain from approaching the sign. The visual signaling system may include a plurality of smart signs which display different patterns on different signs depending on the location of each sign relative to the hazard, thereby guiding individuals away from the hazard.

A vehicle barrier gate arm has an anti-roll end cap which prevents the gate arm from rolling when it has become detached from its gate operator. The end cap comprises a distal outer panel and three or more protrusions positioned radially equidistant along the periphery of the distal outer panel. The protrusions extend outward from the distal outer panel perpendicular to the gate arm. The protrusions may form a square, triangle, trapezoid, or cross and may taper inward in a proximal direction or may meet the outer cuff at a sharp angle. Furthermore, an outer and inner cuff form a friction fit with the end of a gate arm to removeable attach the end cap to the distal end of the gate arm.

A charging stand is a power supply facility that is able to be housed underground. The charging stand includes a light emitting device and a control device. The light emitting device is configured to emit light to a space above the ground. The control device is configured to control the light emitting device. A first light emission mode of the light emitting device for when the charging stand is available and a second light emission mode of the light emitting device for when the charging stand is not available are different.

A mobile emergency light device includes a casing (1), a moving closure cover (2), a translucent lens (3), an electronic circuit board (5) for control, and a combined reflector (4), in which the combined reflector (4) has an inverted bell shape and is open at both ends, in which the electronic circuit board is securely connected to the combined reflector (4), and provided with a plurality of light-emitting diodes (LED), suitably angled towards the combined reflector (4), and in which the casing (1) forms inside this a cylindrical cavity (13), whose interior houses an automatic switch, driven by the base of the casing approaching a ferromagnetic material.

An improved detector device for locating studs and other objects behind a substrate (such as a wall) uses one or more light emitting diodes (LEDs) in combination with a photochromic compound to mark the locations on the substrate behind which objects are located.

A blade-height optimization indicator for a table saw determines based on the rotational position of one or more blade guards of the table saw as they are displaced by a workpiece being cut whether the blade-height of the table saw is optimized relative to the thickness of the workpiece and provides a visual GO/NO-GO indication depending on whether the blade-height is determined to be optimized.

A display device includes a first wall, a second wall disposed opposed to the first wall, a third wall disposed in a direction crossing the first wall and the second wall and provided with a mounting portion, a substrate disposed between the first wall and the second wall and provided with a light emitting portion, and a display portion to permit transmission of light irradiated from the light emitting portion and mounted on the mounting portion. As viewed in a direction perpendicular to a normal direction of the substrate and parallel to the first and second walls, a distance between the first wall and the second wall is shorter than a length of the substrate, and the substrate is inclined with respect to the first and second walls.

An indicating device includes an enclosure and an indicating lamp. The enclosure includes a base. The base defines a receiving space and an opening communicating with the receiving space. When the indicating lamp is received in the receiving space, the base partially shields the indicating lamp allowing light from the indicating lamp to be transmitted only through the opening.

An electronic device with an auxiliary lighting function and an operation method thereof are provided. The electronic device includes a first body, a display screen, and a light-emitting module. The first body has a first surface. The first surface includes a screen area and a border area. The border area surrounds the screen area. The display screen is disposed in the screen area of the first body. The light-emitting module is disposed in the border area of the first body. The light-emitting module provides an illumination light in at least one first area of the border area, and provides an indicating light in at least one second area of the border area.
