A recently granted patent (Publication Number: US11683877B2) describes a communication adaptor that enables wireless communication between lighting converters and control interfaces. The adaptor is housed within a casing and includes an adaptor antenna for wireless communication, a wired control interface connected to wired control interface terminals, and a control circuitry. The control circuitry converts wireless signals received by the adaptor antenna into wired control interface signals to be supplied to the wired control interface terminals. The adaptor is designed to establish wireless communication by coming into close contact with a converter antenna of a lighting converter.

The communication adaptor is powered by a DC voltage at the wired control interface terminals and is mechanically engaged with engagement means of the converter, allowing for the attachment of a strain relief module. The casing of the adaptor is equipped with means for mechanically fixing it to the casing of the converter, ensuring that the overall height of the converter casing is not increased. Additionally, the casing of the adaptor may have snap-on connection means for easy attachment to the converter casing.

The wired control interface of the adaptor includes switching means for selectively short-circuiting the wired control interface terminals, enabling the transmission of data onto the connected wired control interface. The control circuitry is designed to convert received wired control interface signal blocks into near field communication bursts, and vice versa. The casing of the adaptor is partially made from metal, and the converter antenna is arranged to avoid being shielded by the casing.

The communication adaptor also features input and output terminals for looping through a mains power supply to the converter for lighting means. Furthermore, a kit is described in the patent, which includes a wireless communication enabled converter for lighting means and the communication adaptor.

The wired control interface of the communication adaptor can be a DALI interface, and the adaptor antenna is a near field communication antenna. Additionally, the control circuitry is capable of converting wired control interface signals into wireless signals.

Overall, this patent describes a communication adaptor that facilitates wireless communication between lighting converters and control interfaces, offering convenience and flexibility in lighting control systems.
