The invention provides a lighting device, comprising a light exit chamber (), delimited by a light exit body (), a plurality of light sources (), positioned within the light exit chamber (), and arranged to emit light in the direction of the light exit body (), an optical processing element, adapted to process the light emitted from the plurality of light sources (), and a transparent antenna element (), extending into the light exit chamber () and positioned relative to the plurality of light sources () such that each light source is arranged to transmit light toward the antenna element, wherein said transparent antenna element () is separate from the optical processing elements, wherein the transparent antenna element () being transparent for the light emitted by the plurality of light sources (), and the antenna element () comprises: a transparent conductive material that is self-supporting.

Lighting device with wireless control element

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

A theftproof lamp (), including a lamp body () and a lamp cap (). A spring member () and a ratchet wheel mechanism () are provided inside the lamp for cooperating with each other and enabling theftproof effect. When turning the lamp clockwise, the lamp can be screwed down to a lamp socket. When turning the lamp counter-clockwise, the lamp can only make repetitive circular motions around the ratchet wheel and therefore achieve the theftproof effect. When a user needs to remove the lamp in a safe way, a bolt () can be moved inwardly to block the spring member from moving upward, so that the lamp body, ratchet wheel and lamp cap form a whole, without any movement in relation to each other, and therefore allowing easy removal of the lamp.
