Introduction to LED Indicator - Discrete

Light-emitting diodes (LEDs) are among the most versatile electronic components available. LEDs offer consistent illumination and can be used in a wide variety of applications. These applications range from simple device-level indicators to complex optical systems and displays. One of the most common uses of LEDs is in discrete indicator applications.Discrete LED indicators are used extensively in electronics and industrial systems, for no other reason than to give a visual feedback about the status of equipment or when input switched have triggered an action. The same purpose is often served by minor audible indicators such as buzzers or beeps, but an LED’s uses are far more diverse. In this application note, we will explore how LEDs can be applied within an industrial system.

LEDs vs. Other Discrete Indicators

When selecting a discrete indicator, it is important to understand the differences between LEDs and other technology. LEDs are generally brighter and longer lasting than bulbs and incandescent lamps, making them a better choice in many situations. LEDs are usually visible in direct sunlight, while other forms of lighting can be difficult to see in bright light. LEDs use much less energy than other sources of illumination, making them a practical choice for applications that require a low energy source. LEDs also have a wide viewing angle, making them more visible from off-axis positions. LEDs are also smaller than other types of indicators, which can be an advantage in space constrained applications.

The 12-21/BHC-AP1Q2/2C is designed to be used as a discrete indication and is available in a variety of standard LED colors including red, green, blue and orange. Its bright illumination makes the 12-21/BHC-AP1Q2/2C LED ideal for outdoor applications or those that require long-distance viewing. The 12-21/BHC-AP1Q2/2C is an excellent choice for signaling, alerting and monitoring applications in versatile environments.

Working Principle of 12-21/BHC-AP1Q2/2C

The 12-21/BHC-AP1Q2/2C LED indicator works on a simple principle. It consists of a housing that contains a light source, such as an LED, connected to a power source. When power is supplied to the light source, it emits light. The emitted light is visible to observers, providing a discrete indication of the system’s status. The 12-21/BHC-AP1Q2/2C has two connection points. The first is a ground wire which is connected to the housing and provides a common electrical connection point. The second is the positive wire, which is connected to the light source and provides the power to light the LED.

Applications of 12-21/BHC-AP1Q2/2C LED

The 12-21/BHC-AP1Q2/2C LED is ideal for harsh outdoor applications such as in railway, marine, and aerospace systems. Due to its die cast aluminum construction and rugged housing, the 12-21/BHC-AP1Q2/2C is suitable for use in hazardous areas such as those with hazardous gases and dusts. Additionally, its bright color makes it visible even in direct sunlight, making it a great choice for indication of alarms or equipment status in these conditions. Its small size makes it well suited for use in space-constrained applications. The 12-21/BHC-AP1Q2/2C can also be used as an internal warning light or as a signaling system in industrial automation applications.

Conclusion

In summary, the 12-21/BHC-AP1Q2/2C LED indicator is a rugged, brightly illuminated device suitable for a variety of industrial applications. Its housing is made of die cast aluminum, making it suitable for use in harsh environments where temperatures may range from -40°C to +85°C. The 12-21/BHC-AP1Q2/2C operates on a simple principle in which power is supplied to the light source to emit light, providing an easily visible indication of the system’s status. The 12-21/BHC-AP1Q2/2C is ideal for use in railway, marine, and aerospace systems, as well as in hard-to-reach or space-constrained applications. It can also be used as an internal warning light or as a signaling system in industrial automation applications.
