Embodiment Construction

[0018] In the present disclosure, an air gap is used between the metal luminous body and the metal ceiling plate on which the luminous body is installed. The inventor noticed that the use of an air gap between the metal luminous body and the ceiling plate achieves better radiation properties than the use of holes in the luminous body itself. Moreover, efficient radiation properties can be achieved without the need for such holes in the luminaire, and also without having to rely on external antennas, which may be expensive. It is advantageous to avoid the use of holes in the outer wall of the luminous body because the holes require additional production steps to manufacture, and additional measures are used for safety requirements in use.

[0019] figure 1 It is a schematic block diagram of an embodiment. figure 1 A single luminous body made of any suitable material, but generally made of metal, is shown. The luminous body of this embodiment is a so-called metal device-bracket lu...

Abstract

A luminaire (1) configured for attachment to a suspended ceiling of a space to be illuminated comprises a housing, fixing means for fastening lighting components to said housing, comprising an antenna ( 10), and fastening means arranged to fasten said luminaire relative to the ceiling tile (20). The fastening member may be configured to space the housing from the ceiling tile (20) to provide an air gap (22) between the housing and the ceiling tile (20), whereby The housing constitutes a resonant cavity for RF energy emitted from the antenna (10), the air gap is dimensioned to radiate RF energy from the antenna (10) outside the housing environment of.

Description

Technical field [0001] The invention relates to a luminous body incorporating a wireless transmitter. Background technique [0002] Luminaires (or lamps) constitute the basic components of many lighting solutions (especially smart lighting solutions incorporating light-emitting diode (LED) lighting). Another important component of a smart lighting system is a control module equipped with a radio and an antenna to provide a wireless connection. The control module works in the communication network, and each module constitutes a node of the network. At present, the control module is often integrated in the luminous body. The luminous body is usually made of metal and plastic materials. In particular, many metal parts may have a large influence on the radiation properties of the antenna. The quality of communication within the network (propagation distance and packet error rate (PER)) largely depends on the radiation properties of the antenna integrated in the lighting system. ...
