Designers of Power Tap Systems products.


P Tap® is a transparent lamination of conductive and non-conductive glass. The arrangement allows power or data to be transferred across individual layers within the lamination. Pre-machined apertures create taps to the positive and negative charged inner coatings that supply power delivery to embedded devices. These connected devices appear to be freely floating within an optically clear glass panel with no visible means of power connection.

Removing the need for wires offers designers, architects and engineers limitless design opportunities to locate powered devices within transparent structures. Devices such as USB sockets, induction charging pads, motors, cameras, sensors and digital displays can all be seamlessly integrated.

Early applications include LED lit display cases and shelving units for museums and induction charging ‘smart’ tables for high-end retail stores. Wider applications span a multitude of markets including architecture, security, automotive, retail and lighting.


CompassLED driven by Power Tap® lends itself perfectly to the museum, art and point of sale lighting markets, removing the need for intrusive cables and rod systems to deliver power, thus opening up new design opportunities for lighting designers to locate luminaires where necessary and not where dictated to by the constraints of wires.

The locations of CompassLED lights and number of CompassLED sockets within a panel is fully customisable. The final system offers easy installation, light replacement and adjustment of 360 degree full rotation on all axis, individual or group dimming and the ability to illuminate through the P-Tap® glass panel, offering previously unseen lighting flexibility.
