A hands-free wearable lighting device is a device utilized to provide illumination to the user's surroundings while being worn. At least one multicolor light-emitting diode (LED) is positioned within an LED compartment located on a housing. A control unit, a brightness adjustment switch, and a color adjustment switch allow the user to alter the light of the at least one multicolor LED. A necklace allows the housing to be worn around the user's neck in order to provide hands-free illumination. The user may utilize the device as a handheld light by grasping the device via a finger tab. Additionally, the user may utilize a prop stand to direct the light from the at least one multicolor LED in a desired direction. The device may include a laser diode as well in order to allow the device to emit a laser in addition to regular illumination.

Embodiments of an illuminated wearable device such as a lapel pin are disclosed. A light emitting source such as a light emitting diode is attached to an ornamental element. A detachable clutch containing a power source attaches to a prong extruding from a back side of the ornamental element to advantageously hold the ornamental element in place while conductively connecting the light emitting source to the power source.

A light-transmissive filament is configured to emit light through its side wall. In a first segment, a first proportion of the light received by the segment is emitted through the side wall. In a second segment, a second, smaller proportion of the light received is emitted. A method of producing the light-transmissive filament is also provided.

The present invention discloses a multi-functional battery box, belonging to the field of power supply devices; a multi-functional battery box, comprising: a case, having an accommodating cavity; a printed circuit board, located in the accommodating cavity and permanently connected with the case; a power source, located in the accommodating cavity and in contact with the printed circuit board; an electro-acoustic transducer, permanently arranged on the printed circuit board and electrically connected with the printed circuit board; a spring piece, arranged on the case and in contact with the printed circuit board; a change-over switch, flexibly connected with the printed circuit board; the present invention has two switching modes that can be flexibly switched, making the battery box easier and more flexible to use, reducing the loss to the switch and prolonging the life of the battery box.

A light source comprising a substrate, wherein the substrate is coated with a transflective thin film optical coating, wherein the coating results in a metallic mirror and/or iridescent effect on the substrate; and a light emitting diode comprising an internal circuitry, wherein when the light source in a switched-Off mode the metallic mirror effect or the iridescent effect conceal internal circuitry of the light emitting diode to provide an aesthetic look and color on the gemstone, wherein when the light source is switched-ON the transflective thin film allows LED light to transmit through the substrate, wherein the light source comprises a substantially invisible light source integrated onto a substrate. In other embodiments, LED may include OLED, transparent inorganic LED, flexible COF LED, etc. . . . In embodiments, the gemstone may be foiled, unfoiled, multi-facetted, colorless, colored, etc. . . .

The present invention relates to as battery box comprising a housing and a power supply component mounted within the housing. Through holes are provided respectively on both ends of the housing to lead a wire into the housing to connect with the power supply component. The power supply includes a circuit hoard and a battery. The housing includes an upper housing body and lower housing body which are detachably connected with each other. The upper housing body and the lower housing body could be engaged with each other to form a receiving cavity to receive the power supply component. A contact is provided on the circuit board to be in communication with the battery and correspondingly, a flexible sheet is provided on the upper housing body to press the contact. The present invention further relates to a necklace provided with the said battery box.

A bracelet or flexible band comprised of a flexible member that on one end is interconnected to a knife and on another end, is connected to a sheath that selectively receives the knife in the locking fashion. When needed, the knife is rotated within the sheath to facilitate release thereof from a lock that is integral with the sheath. Once removed from the sheath, the knife can be used for self-defense, cutting rope or cord in an emergency situation, or for general utility cutting tasks.

The present invention discloses an article of jewelry, preferably a necklace with a hologram. The disclosed apparatus is provided with a hologram to display various things within the necklace and make it appear more stylish and enhancing the decorative appeal. The disclosed apparatus is capable of interacting with the multimedia devices like phone and can connect with them to display images and other things present in them via hologram in the necklace.

An sports retronic band for athletes. The invention is configured to be worn around the users wrist like a watch or similar accessories. Power is provided by a battery intended to power the present invention. The invention includes a light portal which projects the desired art. All preprogrammed data/information is transferred from a laptop, computer or tablet.
