LED Stack Light Applications
KNOWLEDGE BASE ---
What is stack light?
Stack light is also called machine status indicator light, signal tower light, andon light, warning light, industrial signal light or tower light. The tower stack lights are widely used on equipment in industrial manufacturing and process control environments for operator stations, call lights, machine monitoring so that they provide visual and audible indicators of a machine's status to machine operators, technicians, production managers and factory personnel. Actually, the machine stack lights identify errors in manufacturing when they happen, which is a form of andon systems.
LED stack light color meaning
LED stack lights are used in all kinds of machines and process environments. There are some special meaning of their colour codes for machine state conditions.
- RED: Failure conditions in manufacturing, such as an emergency stop or machine fault.
- YELLOW: Warnings, such as over-temperature or over-pressure conditions.
- GREEN: Normal machine or process operation.
- BLUE: External help request, where an operator might need raw materials, scheduling or maintenance personnel assistance.
- WHITE: User-defined conditions to a specific machine, it is often related to productivity monitoring.
An optional audible alarm buzzer can be added in stack light, whose volume reaches 70–105dB typically, and stack light with buzzer can alert machine operators to pay attention to the machine conditions in auditory way more obviously.
LED stack light function
Steady light, steady light with buzzer, red flash light, red flash light with buzzer, all flash light and all flash light with buzzer.
Mounting type has foldable type, pole and plate type, L-shape bracket type.
LED stack light advantage
LEDs produce less heat than traditional light sources and have longer service life than traditional bulbs. One watt of LED power can replace the eight watts of a light bulb, making it more energy efficient during use.
