A status signal is a type of beacon which tends to have 2 or more colours to signify the varying status of a machine, process or situation.
Typical colours for a status signal are Red/Green and Red/Amber/Green but this is by no means fixed as LED’s are now readily available in various pure colours from infra-red to ultraviolet.
The signals and colours chosen are often in accordance with current guidelines and standards, but ultimately dictated by the end user’s application.
LED status signals are simple in concept but powerful and effective in application. The ability to combine many small LED’s into a matrix allows for coloured words, shapes and signals to be created to your requirements, increasing their effectiveness.
The variety of LED colours now available makes it easily possible to have a single unit with multiple colours being emitted from a single enclosure which is a great alternative and space saver to having separate beacons. This would have been difficult to achieve with other light sources.
