Helmets and helmet lighting systems for use in demanding environments, such as fire, rescue, police and military applications. The helmets and systems provide one or more of high levels of light emission, long operational life, waterproofing/ability to operate in wet or submerged environments and relatively low weight. In some configurations, a helmet comprises a lighting system including an exterior layer and an interior layer applied to a shell of the helmet. In some configurations, a lighting module having an internal layer and an exterior layer is attached to an underlying helmet. In some configurations, a lighting system includes pods and/or strips containing a source of light. The pods or strips can be attached to an underlying helmet.

A UVC-integrated LED structure adapted to air sterilization-and-disinfection grilles is provided. The UVC-integrated LED structure includes a housing, an opening disposed at top of the housing, multiple wavy grilles engaged with both sides of inner wall of the opening, placement grooves openly disposed at one side of the wavy grilles, and COB light boards disposed inside the placement grooves. The UVC-integrated LED structure installs the COB light boards at the placement grooves. The structure allows the COB light boards to be hidden on the surfaces of the wavy grilles for decreasing height of the COBs. Therefore, air resistance can be reduced when the ultraviolet ray irradiates on the passing air. The impact of dust being adhered to the COB light boards can be reduced. The air passing through the multiple wavy grilles can be sterilized and disinfected.

A portable electric fan is provided and includes a shell, a fan module, and a plurality of combined seat groups. The shell has a first surface, a second surface opposite to the first surface, and a surrounding side surface that is connected to the first surface and the second surface. The shell has a hollow portion. The fan module is mounted in the hollow portion. The combined seat groups are mounted on the surrounding side surface, and each of the combined seat groups includes two bases and a bracket detachably mounted to the two bases. Each of the two bases has a first through hole and a second through hole, and an extending length direction of the first through hole and an extending direction of the second through hole are staggered relative to the surrounding side surface.

An iron according to the present disclosure includes a light emitter that outputs light, and a base surface that transmits the light. A filter that suppresses transmission of visible light is provided between the light emitter and the base surface. According to the iron, the transmission of the visible light through the base surface is suppressed. Thus, the temperature on the clothes can be kept constant regardless of the color of the clothes.

A method of manufacturing a planar light source includes: providing a wiring substrate; locating a light guide plate on a first principal face of the wiring substrate, wherein the light guide plate includes a plurality of unit regions arranged in one dimension or two dimensions, and a plurality of through holes that are open at the a principal face and a second principal face of the light guide plate, wherein at least one of the through holes is located in the unit regions; locating light sources in the through holes in the unit regions on the first principal face of the wiring substrate; locating a first light transmissive member in a first of the through holes; and locating a second light transmissive member in the first through hole.

The present disclosure provides a luminous water outlet device, which includes a hydroelectric power generation module, a waterway separation body, a waterway switching module, a water outlet panel, and a light board. The hydroelectric power generation module is arranged at a water inlet, the waterway separation body has two waterways, the waterway switching module is used to switch a flow of water in the two waterways, and the water outlet panel is correspondingly arranged below the two waterways, the light board is electrically connected with the hydroelectric power generation module. Compared with the prior art, the hydroelectric power generation module is arranged in the water inlet to ensure that the light board works no matter which waterway is opened and allows water to flow through. Further, the present disclosure has simpler installation, smaller volume, and simpler waterway structure.

A cordless light attachment for an object includes a housing that has a proximal end and a distal end, and an interior cavity that extends from the proximal end to the distal end, forming an opening extending through the housing from the proximal end to the distal end. The device receives therein an object and removably attaches to the object. The device has at least one light source powered by a cordless power source arranged on or within the housing.

Systems and methods for interactive objects including illuminated surfaces are provided. An interactive object includes a flexible substrate comprising a soft material that is non-transmissive to light. The interactive object includes a plurality of holes extending from an inside surface of the flexible substrate to an outside surface of the flexible substrate to form a light-transmissive pattern at one or more locations of the flexible substrate. An illuminated surface is positioned adjacent to the inside surface of the flexible substrate with its front surface extending along at least a portion of the inside surface of the flexible substrate at the one or more locations including the plurality of holes. The interactive object includes one or more electronic components electrically coupled to the illuminated surface to control the illuminated surface to provide a visual output.

A lamp and a method for detecting a user's sitting posture are provided. The lamp is adapted to detect the user's sitting posture. The lamp comprises a lamp bracket, an image capturing unit and a processing unit. The image capturing unit is disposed on the lamp bracket and configured to capture a target image towards a desktop. The processing unit is coupled to the image capturing unit, wherein in response to that a head feature exists in the target image, the processing unit is configured to determine a reference information according to the head feature and to determine whether the reference information meets a poor sitting posture condition.

The invention relates to a facade construction, consisting of panels and a framework in the form of vertical struts and horizontal girders covered by profiled covers. At the locations of intersection of the profiled covers, openings are formed for conducting lighting equipment cables, openings are formed in the frontal planes of the profiled covers for light sources, the openings being commensurable with the diameter of the light sources, and the light sources are located in the same plane as the front part of the profiled covers or project insignificantly beyond same. Separate groups of LED light sources can be connected in the internal volume of the profiled covers with the aid of a switching power-supply connector and switching control connector, and electrical power-supply sources and elements for controlling the light sources are mounted in the internal volume of the profiled covers or are located outside the construction system.
