The 551-1107 (the datasheet number) is an LED indicator device that uses an array of ultra-bright LEDs to indicate levels or rates of changes in an electrical/electronic system. It is part of a family of devices that includes Seven-Segment Displays, Bar Graphs and Light Bars, as well as array LEDs. The 551-1107 is a full-height device that is capable of delivering up to 36 discrete LED segments, with an adjustable arrow pointer, to provide the operator with a visual indication of the state or changing state of the system and its respective systems.

Applications and Uses

The 551-1107 LED array can be used in a variety of applications such as aircraft, marine, military, aerospace, railway and transportation lighting, as well as industrial process control. It can be used in these applications to alert operators to changes or status information about the system that the LED is monitoring.

The array LED is particularly suited to applications where time is of the essence. If a system changes from one state to another quickly, then an LED array can be used to indicate the change with greater accuracy than a single LED. LED arrays are also used to even out the light distribution of a single LED\'s light intensity at greater distance.

The 551-1107 is also used in automotive lighting and industrial lighting. The 551-1107 can be used to produce strobes, pulses and changing colors of light to enhance visibility both during the night and day.

Working Principle

The 551-1107 uses an array of ultra-bright LEDs to provide a visual alert or indication in response to an electrical/electronic signal. Each LED is driven by a transistor, circuit, or other driver such as a motorized (stepper) motor. This gives the device an adjustable, dynamic light effect.

The device works by controlling the current flow through each of its LEDs. The current flow is controlled by the driver which is used to activate the LEDs in a specific sequence. The driver will turn on different segments of the array in order to create the desired effect. The driver can also turn on more than one segment at a time in order to produce brighter effects.

In applications where time is a critical factor, the 551-1107 can be programmed to adjust the speed and brightness of the LEDs to ensure that the effect is displayed as quickly and brightly as possible.

The array LED also provides an adjustable pointer that can be used to emphasize its message or alert the operator to a change in the system. This pointer can be set or adjusted to a specific point on the LED array to better indicate the relevant system change.

Conclusion

The 551-1107 is an LED array device that is suitable for a variety of applications requiring visual indications of changes in an electrical/electronic system. Its ability to create dynamic effects using a combination of bright and strobing LEDs allows its use in a variety of environments. Its adjustable pointer can also be used to emphasize the message it is conveying with other visual indicators.
