Latest Patents

One of his latest patents is a tubular device designed for fitting to a tubular light fitting. This innovative solid-state lighting device features a pin safety circuit that is electrically connected to the connection pins at one end. The pin safety circuit includes two protection components of different types. In one example, an electrically controlled isolation switch and an electronic switch function as a high voltage isolation barrier. This design ensures full galvanic contact separation, while the isolation barrier provides current protection if the isolation switch fails. Another example incorporates a mechanically controlled isolation switch along with an electrical or electronic isolation barrier, offering two levels of protection with a single manual operation required by the installer. This design prevents end-of-life protection circuitry from being triggered during installation.

Another significant patent involves a tubular LED lighting device that comprises an LED, a driver for powering the LED, and an electrical connector. This lighting device is equipped with a thermally triggered switch to prevent overheating of the electrical connector. The thermally triggered switch is connected in series between the electrical connector and the driver, interrupting current flow if the temperature of the electrical connector reaches a triggering condition. This innovative feature ensures safety by preventing significant arcing and overheating.
