摘要: 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).
