Panel Indicators, Pilot Lights

Panel indicators and pilot lights (aka. signaling lights) are electronic components that indicate to the user to draw attention to a specific action or event. They are commonly used to provide visual cues, alarms, and sometimes audible feedback when a change in a system state is detected. In most cases, these types of indicators are typically used to provide visual warnings of any potential hazards or malfunctions that may occur in the system.

Panel indicators and pilot lights are often found in industrial and commercial settings, where they are used to provide visual feedback on the performance of various machinery and systems. For example, in industrial manufacturing, they are commonly used to indicate conditions like power on/off, low-flow, high-pressure, and other important states. In commercial settings, they may be used to indicate when to start or stop equipment, confirm the status of an operation, or to provide alarms or warnings.

These types of indicators generally involve the use of two components – a circuit board and an LED light source. The circuit board contains the electrical wiring that is used to power the LED, while the actual indicator itself is the LED light. This LED is designed to provide an illuminated indicator that is either bright or dim, depending on the power applied by the circuit board. By varying the amount of power supplied to the LED, different colors or patterns of light can be displayed.

When a signal is detected from the circuit board, the LED is illuminated. This can be used to display either a single, steady color, or different colors and patterns of light. This allows operators to easily identify the various states of a system, and be alerted to any potential dangers or malfunctions that may be occurring. The most common type of LED used in panel indicators and pilot lights is the dual-color LED, which allows the operator to determine the current state of the system by whether the LED is illuminated or not.

Alternatively, some panel indicators also feature a mechanical or push-button switch for manual control. When the switch is pressed, it triggers the circuit board to either power on or off the LED light, thus allowing the user to manually control the system state. This can be particularly useful in certain applications, where manual control is required.

Overall, panel indicators and pilot lights are a very useful and versatile tool for providing visual feedback and indications in industrial, commercial, and various other settings. By providing simple visual alerts, they can be used to both allow operators to easily identify a system state and alert them to any potential dangers or malfunctions. Thus, they have become an essential component in many industrial and commercial systems.
