Discrete LED indicator is a small device that is used in various applications such as automotive, medical, industrial, and home. One of the most popular LED indicators is HSMQ-C120, which has a wide range of application field and is suitable for many operating conditions. In this article, we will discuss the HSMQ-C120 application field and working principle.

HSMQ-C120 Application Field

The HSMQ-C120 uses a bright red LED mounted on a plastic housing. The size of the indicator is 6mm or 8mm and the power consumption is low. This low power consumption is ideal for applications that require long running time yet high performance. The maximum forward voltage is 5V, with a typical output intensity of 30mcd. This means the indicator is very bright and easily visible in low-light areas.

The HSMQ-C120 can be used in a variety of applications, such as automotive, medical, industrial and home. In automotive applications, the indicator can be used to provide warnings or notifications such as a door open indicator or low voltage warning. In medical applications, the indicator can be used to provide safety control such as a blood flow monitor or heart rate monitor. In industrial applications, the indicator can be used for continuing operation tests or process monitoring. Finally, in home applications, the indicator can be used as a visual aid to help the user use their appliances or electronic equipment.

HSMQ-C120 Working Principle

The HSMQ-C120 indicator operates using components such as LEDs, resistors, and transistors. When a voltage is applied to the LED, it allows for the flow of current which causes the LED to emit light. The size of the current is determined by the characteristics of the resistor, which is then subjected to the voltage drop due to the transistor. By modifying the transistor, the amount of current is controlled and the LED brightness can be modified accordingly.

In order to properly operate the LED indicator, the LED needs to be connected in series to the circuit. The LED is connected to the resistor, which is then connected to the transistor. The transistor acts as a switch, where it can either allow or stop the flow of current. By controlling the flow of current, the amount of light emitted from the LED can be controlled. Additionally, since the LED is in series, the amount of current is split between the LED and the resistor, which allows the user to control the intensity of the light.

Conclusion

The HSMQ-C120 is a popular discrete LED indicator that can be used in a variety of applications. This indicator provides a bright and vibrant light output, along with low power consumption, making it ideal for applications that require long running time yet high performance. The working principle of the indicator is based on the flow of current through the LED, the resistor and the transistor, allowing the user to control the amount of light emitted. The HSMQ-C120 is a great indicator for providing notifications or warnings, as well as driving visual aids for the user.
