The communication booth includes a booth body, a wireless network module, a charger module, a germicidal lamp, a control module, and at least a sensor. The booth body includes a booth enclosure and a booth door configured to a lateral side of the booth enclosure. The wireless network module, the charger module, and the germicidal lamp are configured inside the booth enclosure. The control module is electrically connected to the germicidal lamp and the sensor. The communication booth may provide wireless network service through the wireless network module, and charging service through the charger module. The control module controls the germicidal lamp to disinfect and sterilize the booth body. The sensor may detect activities inside or around the booth body. The control module, based on the detection from the sensor, turns off the germicidal lamp so as to avoid harms to people.

A portable illumination apparatus having a sterilizing function, the illumination apparatus including: a lamp unit which includes an illuminating light element on an interior side of the lamp unit; a base coupled to the lamp unit by a hinge; and a sterilizing light element located on the interior side of the lamp unit. When the lamp unit is in a closed position with the base, the lamp unit and the base meet at a boundary section to form a cylinder with a top and a bottom. Also, the boundary section is substantially mirror-symmetrical and at least partially U-shaped such that the lamp unit has a longest height line and a shortest height line. Additionally, the illuminating light element is arranged on or along the longest height line and the hinge is formed about the shortest height line.

The present invention provides: an interior material having a surface layer which has visible light-responsive photocatalytic activity and which contains two types of titanium oxide microparticles, the two types of titanium oxide microparticles comprising first titanium oxide microparticles, in which a tin component and a transition metal component for enhancing visible light responsiveness (excluding iron group components) are in solid solution, and second titanium oxide microparticles, in which an iron group component is in solid solution; and a method for manufacturing the interior material. The present invention makes it possible to provide an interior material in which visible light-responsive photocatalytic titanium oxide microparticles, which make it possible to easily produce a surface layer (photocatalyst thin film) having high transparency and expressing photocatalytic activity even in response to visible light (400-800 nm) only, are applied onto a surface, whereby it is possible to obtain, under indoor illumination, excellent photocatalytic properties such as an antimicrobial property and a property of breaking down chemical substances in indoor air without adversely affecting the design quality of the article in question.

UV hard-surface disinfection system that is able to disinfect the hard surfaces in a room, while minimizing missed areas due to shadows by providing multiple UV light towers that can be placed in several areas of a room such that shadowed areas are eliminated and that can be transported by a cart that is low to the ground such that the towers may be loaded and unloaded easily by a single operator. The system is able to be controlled remotely, such that during activation of the system, no operator is present, and to automatically cut power to all towers in the event that a person enters the room.
