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.
