  • Tubular device for fitting to a tubular light fitting
    Patent number: 11137119
    Abstract: A tubular solid state lighting device has a pin safety circuit electrically connected to connection pins of the one end. The pin safety circuit comprises two protection components, of different types. In one set of examples, there is an electrically controlled isolation switch and an electronic switch which functions as a high voltage isolation barrier. The switch provides full galvanic contact separation, whereas the isolation barrier provides current protection if the isolation switch is not functional. In another set of examples, there is a mechanically controlled isolation switch and an electrical or electronic isolation barrier. This provides two levels of protection, but requiring only a single manual operation by the installer of the lighting device. It avoids end-of-life protection circuitry being triggered during the installation of the lighting device.

A lamp is identified from the patterns by a camera-equipped mobile device. The mobile device then causes the identified lamp to generate a position-determining pattern of light. The mobile device determines its own position relative to the lamp based on the pattern of light received by the camera. The mobile device then instructs the digital lampshade, according to user input, to allow illumination or to provide shade at the determined position of the mobile device.
