Introduction

The LA M676-Q2T1-1-Z is a discrete LED indicator from Litronix. It is a bright, single color, low-power indicator whose function is to provide visual indication or feedback on the status of a device or machine. It offers excellent visibility both day and night, making it an ideal choice for applications in commercial and consumer products. In this article, we will discuss the application field and working principle of the LA M676-Q2T1-1-Z.

Application Field

The LA M676-Q2T1-1-Z is most suited for applications such as vehicular (car or truck) warning or indication lights, domestic appliances, office equipment, and computers. It can also be used for general LED indicator functions such as power on, power off, low-battery, or on/off indicator for switches/dimmers, etc. The LED indicator is also suitable for applications such as medical equipment, toy design, handheld displays and home security systems, again due to its wide viewing angle, low power consumption and bright output.

Working Principle

The LA M676-Q2T1-1-Z is a low-power discrete LED indicator. Inside, it has two circuits: the power circuit and the LED circuit. The LED circuit is made up of a single LED element, which is wired with an electrical connection to a power source. When the LED is powered on, it will emit light. The LED\'s polarity must be connected properly to the power source. Reverse polarity may damage the LED. The power circuit is made up of a current-limiting resistor, which regulates the voltage supplied to the LED. This prevents the LED from being over-powered and ensures that it only draws the correct amount of current and voltage. The power circuit also provides protection against stress and electro-static discharge (ESD). This prevents the LED from being damaged during handling and use.

Conclusion

The LA M676-Q2T1-1-Z is a discrete, low-power LED indicator that is ideal for a variety of applications. Its wide viewing angle, bright output and low power consumption make it an excellent choice for applications in vehicular, commercial, or consumer products. Its power and LED circuit ensure that the LED is protected from over-powering, stress, and ESD.
