LED Indication - Discrete

LED indicators have been used in electronic systems for decades. They provide a simple and inexpensive way to provide system status indications to the user. They are made from a number of different materials, such as plastic, metal and hermetic seals, which provide a distinct level of robustness and performance.

The HLMPQ105AGR is a discrete LED indicator, which is used in a variety of applications. It takes the form of a cylindrical package, with a metal flange on one end and a glass lens at the other. It contains a single standard color LED mounted on a ceramic substrate. It is available in both 120° and 180° viewing angles.

Application Field

The HLMPQ105AGR can be used in a wide range of applications. Some of the most common applications are as follows:

• Building Access Control – The indicator can be used for keypad entry systems to show access rights.
• Industrial – Used in industrial control systems, the indicator is often used to provide status information to operators. For example, it may be used to show if a system is in maintenance mode.
• Surveillance – Night vision cameras and motion sensing systems often utilise the indicator to indicate motion detection or to provide information on the status of the surveillance system.
• Automotive – The indicator can be used in a variety of automotive systems to show system status or to provide warnings to drivers and passengers.
• Medical – The indicator can be used in medical equipment and applications, such as MRI, X-Ray and ultrasound systems, to provide critical status and diagnostic information.

Working Principle

The HLMPQ105AGR is a single standard color LED, mounted on a ceramic substrate. The LED is powered by a DC voltage. In a typical application, the LED is powered at 12V or 24V, depending on the application. When power is applied, the LED will emit a light in the visible spectrum.

The LED package is hermetically sealed, ensuring that the LED is moisture and dustproof, providing additional reliability and extended life. The LEDs are also rated to be able to operate in temperatures ranging from -40 to 110°C (-40 to 230°F).

The LED emits a single wavelength of light, depending on the model of LED used. The LED can emit light in a range of colours between red and green.

Conclusion

The HLMPQ105AGR is a single standard color LED indicator, used in a variety of applications. It is hermetically sealed ensuring that it is moisture and dustproof and able to operate in a range of temperatures. The LED emits a single wavelength of light, which can be adjusted according to the specific application.

The HLMPQ105AGR provides a simple and inexpensive way to provide system status indications to the user, and is an ideal choice for applications where reliability and robustness are paramount.
