A lighted sports court floor mop designed for drawing visual attention to itself. It has a circular mop body with a ring of downward facing LEDs imbedded about the entire perimeter of the mop head body. These LEDs face downward when the mop head is in use on the floor, and are not visible when the mop is in use, as they are embedded in the bottom face of the mop head. The light emitted from these LEDs is not directly visible when the mop is in use but rather the light directly emitted from the LEDs is reflected off of the floor to outside of the mop body so the viewing public sees the illusion that the mop body is floating above the court floor. A video display panel may be optionally mounted on the top deck of the mop head that is horizontally or vertically disposed. The lights and video display panel are operated by a pole handle mounted switch that operates the control module. The control module and its power source are housed in the mop body.

Provided is an electric device including: a main body comprising a storage chamber with an opening; a door coupled to the main body and comprising a transparent display panel such that the transparent display panel covers at least a part of the opening when the door is closed; a movement detector being configured to detect a movement of the transparent display panel and output a movement detection signal corresponding to the movement; and a controller configured to identify a position of the transparent display panel based on the movement detection signal, and control the transparent display panel to reverse an image displayed on the transparent display panel based on the identified position of the transparent display panel being changed from a first position to a second position.

The present invention aims to provide a luminescent curved glass which, despite being curved with a small radius of curvature, can provide a clear display on its entire surface when irradiated with light, and curved digital signage including the luminescent curved glass. Provided is a luminescent curved glass including a laminate including a transparent plate having a radius of curvature of 3,000 mm or lower and a luminescent sheet, the luminescent sheet containing a thermoplastic resin and a luminescent material that emits visible light having a wavelength of 380 to 750 nm under excitation light.
