摘要： A circuit board on which the electronic components providing power to a series of light sources is positioned as near as possible to light sources in order to minimize parasitic energy losses which would be introduced by lengths of wiring. The light sources are usually elongate tubular Cold Cathode Fluorescent Tubes arranged parallel to one another in a single plane and the circuit board may be mounted directly over the light sources, towards one end of the tubes. Standard PCB board-to-board connectors may be provided at an edge of the circuit board and a further circuit board provided with a series of conductive tracks may provide both a mechanical and electrical connection between the circuit board and the light sources. A power distribution method is also disclosed in which both current and temperature of the light sources are monitored and regulated in order to extend the lifetime of the light sources and to stabilize their brightness.

摘要： A gaming system including an electronic gaming machine (EGM) having a backlit video display, is described. In particular, the EGM can be configured with a display that allows display elements, such as mechanical stepper reels, positioned behind the display to be either revealed or obscured by using directional lighting. The display assembly can include an edge-lit light guide having different regions that can extract light coming from a particular direction.
