A lighting device, such as a replacement lighting device, comprising a light source (LS), e.g. LEDs, for producing light along an optical axis (OA). A heat sink (HS) made of a material with an electrical resistivity being less than 0.01 Ωm, e.g. a metallic heat sink being a part of the housing, transports heat away from the light source (LS). A Radio Frequency (RF) communication circuit (CC) connected to an antenna (A) serves to enable RF signal communication, e.g. to control the device via a remote control. Metallic components, including the heat sink (HS), having an extension larger than 1/10 of a wavelength of the RF signal are arranged below a virtual plane (VP) drawn orthogonal to the optical axis (OA) and going through the antenna (A). Hereby a compact device can be obtained, and still a satisfying RF radiation pattern can be obtained. The antenna can be a wire antenna or a PCB antenna, e.g. a PIFA or a IFA type antenna. In a special embodiment the antenna is formed on a ring-shaped PCB with a central hole allowing passage of light from the light source. Preferably, the antenna is positioned at least 2 mm in front of the heat sink (HS).

A direct current power system is joined to the plurality of strobe lights and further comprising a printed circuit board electrically coupled to radio frequency relay switch, and a battery. A wireless remote is communicatively coupled to the radio frequency relay switch. Activating the wireless remote directs the printed circuit board to provide power to the plurality of strobe lights creating the emergency notification.

The illuminated press on nail is a press on nail. The press on nail is a cosmetic structure that is worn by a client on a location selected from the group consisting of a finger nail and a toe nail. The illuminated press on nail comprises a press on nail, a control circuit, and a personal data device. The control circuit mounts is an illumination circuit that mounts in the press on nail. The personal data device forms a wireless communication link with the control circuit. The personal data device controls the operation of the control circuit. By controlling the operation is meant the personal data device controls the color of the illumination generated by the control circuit.

Disclosed are systems, kits and methods for smart footwear for dance performances, as well as computer-implemented methods to train performers using the smart footwear. An example method for improving a dance technique or a dance performance by a performer, comprises receiving, using a radio frequency (RF) transceiver on a wireless device, a signal from an RF transmitter on a pointe shoe, determining, based on the signal, an activation status of each of a plurality of pressure sensors on the pointe shoe, and providing, based on the activation status, an indication of an accuracy or efficacy of the performer standing en pointe during the dance technique or dance performance.

A lighting assembly includes an upper mount having a pan gear and a plurality of indicator flanges. A lower mount is operably coupled to the lower mount and includes a pan motor and a tilt motor. A printed circuit board is operably coupled to the upper mount and includes a plurality of sensors.
