An apparatus, system, and related methods for light reflection with grooved surfaces are provided. The light reflection apparatus with grooved surfaces has a first surface with a quantity of grooves therein. A second surface has a quantity of grooves therein. The grooves in the second surface have a different angular shape, different size, different angular orientation, or a different unit density than the grooves in the first surface. At least one light source emits light on the first and second surfaces. As a direction of the emitted light changes relative to the first and second surfaces, the quantity of grooves in the first or second surface reflect the light independently of one another.

An animated facemask apparatus is provided. The apparatus includes a face shield, an adjustable headband, and a controller. The face shield is adapted to be worn over the nose and mouth of a user and includes an LED array comprising a plurality of LED elements illuminated to display various shapes, objects, and figures about the user's mouth. The adjustable headband is coupled to opposing ends of the face shield and is configured to wrap around the back of the user's head to secure the face shield over the user's face. The controller is coupled to the headband and includes a central processing unit this is in electric communication with the LED array to transmit commands to the LED array.

Devices, a set of devices, and methods are described to create coordinated, or synchronized, displays of colors by worn fashion accessories, such as necklaces, earrings, shoes, belts, and the like. A master device is defined that sends broadcast, wireless commands to slave devices, which respond with colors and timing in a synchronized way, typically to enhance the experiences of the wearers. Synchronization may include simultaneous lighting, sequential lighting, the same color or coordinated colors. A group ID in messages is defined so that a first set of fashion accessories on a first group of wearers may be controlled by one master, while a nearby second set of fashion accessories worn by a second set of wearers controlled by a second master do not conflict. Operation, including changes from a standby state to an operational state is automatic, using, for example motion detection.

A light system is provided. The light system includes a top housing, a bottom housing, and a side surface extending between the top housing and the bottom housing. An angled reflective surface is arranged between the top housing and the bottom housing and a lighting element is arranged between the top housing and the angled reflective surface. The lighting element is configured to direct light toward the bottom housing to reflect off of the angled reflective surface and out of the side surface.

The invention discloses a coupled power generating device, a power-generating insole and a light emitting shoe, the device comprising a column-shaped hollow shell, at least one group of magnetic induction coils that is provided on the outer wall of the column-shaped hollow shell, at least one removable column-shaped magnet that is provided on the inner wall of the column-shaped hollow shell, two triboelectric nano generating units that are provided at both ends of the column-shaped hollow shell. The coupled power generating device has the advantages of long service life, high output current, stable electrical performance and compact size.

A decorative item including an element made at least partly of a metallic, polymeric or ceramic based material and including a face visible to an observer, at least one light source external or internal to the element, the decorative item further includes at least one optical fibre embedded in the material of the element, the optical fibre serving as a guide for the light from the light source in order to produce, during use, a light effect on the visible face of the element. A method for manufacturing the decorative item is also disclosed.

A desired design is created by use of clear and opaque sections and then illuminated by a light material viewing effect in an article of manufacture.

A lighting system for a hat includes a front housing containing lighting elements that mates with a back plate positioned on the inside of the hat. Driver circuitry controls operation of the LEDs for various lighting modes, and a cover for the front housing is translucent and designed in the shape of a recognizable logo or other design. Electric power comes from a battery located on the back plate, and is provided through the hate using prongs or projections that pass through the hat, from the back plate to a circuit connector in the front housing. The circuit connector is electrically coupled to circuitry on a circuit board in the front housing.

The invention discloses a coupled power generating device, a power-generating insole and a light emitting shoe, the device comprising a column-shaped hollow shell, at least one group of magnetic induction coils that is provided on the outer wall of the column-shaped hollow shell, at least one removable column-shaped magnet that is provided on the inner wall of the column-shaped hollow shell, two triboelectric nano generating units that are provided at both ends of the column-shaped hollow shell. The coupled power generating device has the advantages of long service life, high output current, stable electrical performance and compact size.

A light symbol projection device is disclosed. The light symbol projection device has a housing which is temporarily secured within a receiving mechanism. The receiving mechanism is embedded within a product such as, for example, a shoe. The light symbol housing may project, in various colors, a word, pattern, symbol, logo or other indicia on the ground. The light symbol housing may be interchangeable so that the receiving mechanism may receive various light symbol housings having different light projections. In one embodiment, a speaker associated with the device may also provide an audible sound.
