Safety lighting for emergency escape passage and illuminated guidance system for controlling safety lighting consists of panel of LEDs providing both lighting and information signs

摘要

The lighting is in the form of a panel (10) of high power LEDs (11) (low power consumption with high illumination power). These can be energised individually to provide passage illumination, or in groups, e.g. (12), to provide information such as no access and direction to next emergency access. Control is through a LON connection (13) receiving broadcast/multicast packets from a network (14). Smoke detectors can be integrated with the light fitting.
