A reflectivity in the region of the light source installation surface in which the low reflection pattern is formed is less than a reflectivity in a region other than the region in which the low reflection pattern is formed.

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).

Provided is a light source system, including: a light-emitting module configured to emit first light along a first light path and second light along a second light path; a wavelength conversion device configured to receive the first light and emit excited light with a color different from the first light; and a compensation device configured to guide the second light and adjust its luminous intensity distribution so that the luminous intensity distribution of the second light exiting from the compensation device is substantially identical to the excited light. The compensation device includes a compensation element configured to adjust luminous intensity distribution of a light beam so that an emergent light beam of the compensation element has reduced overall luminous intensity compared with an incident light beam. The second light exiting from the compensation device is combined with the excited light to form third light.
