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 Ultra Violet.
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 and appeal.
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 3 separate beacons. This would have been difficult to achieve with a filament lamp or other light sources.
With the obsoletion of filament bulbs, LED products are fast becoming the chosen product for status signals for many reasons; the biggest reasons being they are low maintenance and low power consumption. With an LED unit the ability to be easily switched on and off is almost instant thanks to the use of an electronic circuit board, this makes the pulsing and brightness control relatively simple for LED signals.
