Antenna

The present invention relates to a lighting device () comprising an envelope (), a carrier () arranged inside the envelope () and having solid state light sources () mounted on the carrier (), driver circuitry () spaced apart from the carrier (), at least one power line () connecting the solid state light sources () and the driver circuitry (), and a wireless communication circuit () for receiving control signals, and for controlling the light output, during operation, from the solid state light sources (). The wireless communication circuit () is connected to the at least one power line () for using the at least one power line () as a wireless communication antenna.

Lighting device having a wireless communication antenna

A lighting device is disclosed. The lighting device comprises: a solid-state lighting element; a radio frequency communication unit for wireless communication between the lighting device and an external device; a light guide having a circumferential edge, wherein the light guide is adapted to couple in light emitted by the solid-state lighting element and to provide illumination to the surroundings of the lighting device; and a metal strip extending along at least a portion of the circumferential edge of the light guide, wherein the metal strip is in thermal contact with the solid-state lighting element and the light guide, and wherein the metal strip is coupled to the radio frequency communication unit so as to operate as an antenna for the radio frequency communication unit.

Solid-state lighting device having a wireless communication antenna

An electronic device () is provided, having a housing (). The housing has a cooling chamber () and a wireless-communication chamber (). The cooling chamber comprises an electronic circuit () embedded in potting material. The potting material is arranged to conduct heat away from the electronic circuit. The wireless-communication chamber comprises a radio-frequency (RF) antenna () for wirelessly receiving one or more commands controlling the electronic device. The cooling chamber and the wireless-communication chamber are physically separated so that the radio-frequency antenna is free from potting material wherein the cooling chamber and the wireless-communication chamber share a common separation wall () formed from a non-conducting material to separate the cooling chamber and the wireless-communication chamber, and the separation wall () forms a non-zero angle with respect to a top opening of the housing (). Eliminating potting material from the antenna by using separate chambers improves wireless transmission/reception efficiently. The design is suited for a lamp, in particular a LED lamp having an AC/DC converter which requires cooling in use. At least part of the housing may be formed from a heat-dissipating material, the potting material being arranged to conduct heat away from the electronic circuit () to the heat-dissipating part of the housing.

Electronic device, LED lamp and method of manufacturing

The present invention relates to a lighting assembly (), comprising at least one light source (), a heat sink () for dissipating heat generated during operation of the at least one light source (), a lamp foot for connecting the at least one light source to a power supply, a control unit for controlling the at least one light source, and a first antenna arrangement () connected to the control unit and being electrically insulated from the heat sink () and the lamp foot (), wherein the heat sink () and the lamp foot () form a second antenna arrangement (), and the first antenna arrangement () is arranged in close vicinity of the second antenna arrangement () for allowing near-field coupling of a radio frequency signal provided to control the at least one light source ().

Controllable lighting assembly

The invention provides a lighting device () and a luminaire (). The lighting device comprises a light emitter () thermally connected to a heat sink (). The lighting device further comprises a communication circuit () coupled to the heat sink for transmitting and/or receiving a communication signal. A first conductive part () of the heat sink comprises at least a first pole () of a dipole antenna () for transmitting and/or receiving the communication signal via the heat sink. This first pole of the dipole antenna may be induced via a primary radiator () to activate the gap ().

Lighting device and luminaire comprising an antenna

The invention provides a lighting device () and a luminaire (). The lighting device comprises a light emitter () thermally connected to a heat sink (). The lighting device further comprises a communication circuit () which is coupled to the heat sink for transmitting and/or receiving a communication signal. The heat sink is electrically conductive and comprising an opening () having dimensions for constituting an aperture antenna () for a particular frequency for directionally transmitting and/or receiving the communication signal of the particular frequency via the heat sink. In the embodiment shown, the lighting device comprises an aperture antenna () and a further aperture antenna ().
