A housing including a body, a lid, a plurality of light sources, and a power source. The body includes a top opening, a base, and at least one side wall. The top opening, the base, and the at least one side wall all define a cavity therebetween. The lid is pivotably coupled to the body and movable from a closed state covering the top opening to an open state. The lid includes a translucent screen that is positioned on an underside of the lid. The plurality of light sources are disposed within the lid. The power source is electrically coupled to the plurality of light sources to provide electrical power thereto.

Embodiments herein describe systems and methods for visually identifying a wheeled robot and associating the wheeled robot with a company or brand. Some embodiments provide a cover, casing, or skin that may be removably attached to the wheeled robot. The casing may feature a pattern, logo, or visuals that are associated with the company. The casing may further conform to features of the movable robot such that the casing does not impede the robot from moving and performing functions, such as transporting objects. The casing may further have a flap that removably attaches to the casing to allow access to the wheeled robot.

Disclosed is a wheel dynamic imaging display rack which comprises a frame. A sleeve is fixed to the frame. A hollow shaft motor is fixed to the sleeve. The hollow shaft of the hollow shaft motor is fixedly connected to the wheel through the sleeve, the hollow shaft motor can drive the flange, the wheel and the LED lamp blade to rotate, and clear images are shown in the LED lamp blade.

Light emitting diode (LED) light tubes having rotatable end cap assemblies are described. The LED light tubes include a hollow tube and a circuit board with LED chips thereon. The end cap assemblies are provided on either end of the tube. Each end cap assembly includes a socket cap, a plug having a plug body and at least one connector, and an end cap body, one end of which engages one of the ends of the hollow tube. A cam locking mount that is positioned within the plug body and on the opposite side has projections to be positioned in the bore of the end cap body. A rotation cam is seated in the cam locking mount and provides for controlled rotation of the LED tube relative to the end caps. Methods of installing the LED light tubes in new installations and retrofit installations and for use in sign assemblies are also described.

A planar component and a method of manufacturing thereon includes an integrated display device for digital information display, comprising a glass pane, at least one screen module, and a controller for controlling and supplying energy to the screen module. A front surface of the screen module forms at least a part of a front side of the component, and the remaining part of the front side of the component is formed by the glass pane.

A light fixture sign includes a sign message structure including letter-shaped structures. The light fixture sign includes an illumination source to generate light to be projected through a front surface of the letter-shaped structures. The light fixture sign includes at least one reflective mirror having a first surface attached over a back surface of the letter-shaped structures and a reflective surface opposite the first surface to reflect light.

A display device includes a transparent light guide plate having an incident surface to display a plurality of patterns viewable in different directions and at least one light source facing a part of the incident surface. The light guide plate includes, on a first surface of the light guide plate, a plurality of prisms arranged along each of the plurality of patterns. The plurality of prisms have, for each pattern, reflection surfaces that reflect light emitted from the at least one light source and entering the light guide plate through the incident surface in a direction in which the pattern is viewable.

Provided is a polarizing element which has an excellent antireflection function as being applied to an image display device; and a circularly polarizing plate and an image display device, each of which has the polarizing element. The polarizing element has an alignment film and an anisotropic light-absorbing film formed using a dichroic substance, in which a degree S of alignment of the anisotropic light-absorbing film is 0.92 or more, and an average refractive index n.sub.ave at a wavelength of 400 to 700 nm of the alignment film is 1.55 to 2.0.

An illuminable image includes a substrate, a transparent light directing channel printed on the substrate, and an image printed over at least a portion of the printed transparent light directing channel.
