Its superior light transmission makes it also suitable for directional signalling in audio and video applications. Additionally, the XZM2CYK53W-8 series is also used in mobile phones, either as a notification indicator or to indicate when the phone is in use.

In the automotive industry, the XZM2CYK53W-8 series of LEDs is used in dashboard instrumentation, warning lights, and indicators for features such as tire pressure or for the door being open. In medical equipment, this series is used for monitoring vital signs and for warning about malfunctions or contaminated products.

Working Principle

The XZM2CYK53W-8 series has a common circuit architecture. They consist of a current-regulated LED string in series with a low-dropout voltage regulator driver. The voltage regulator driver sets the current in all LEDs to a similar value. The voltage regulator driver, the LED string, the LED string capacitance, and the LED string resistance form a frequency-controlled oscillator, which is used to control the brightness.

The voltage regulator driver sets the current through the LED string, and the oscillator, which is controlled by the LED string capacitance and resistance, controls the operating frequency. The frequency varies between 180 and 1000KHz, depending on the capacitance and resistance of the LED string. The varying frequency is determined by the capacitance of the LED string and the resistance of the LED string will determine the brightness and dimming effect, respectively.

The XZM2CYK53W-8 series of LEDs offers a wide range of operating voltage, achieving a brightness level that is equivalent to that of conventional LEDs. Its maximum rated power is 24.6W and the maximum operating temperature range is -40°C to 105°C. Its thermal performance is also excellent, with a thermal coefficient of 1.29mW/K.

In summary, the XZM2CYK53W-8 series of LEDs is widely used in various applications, due to its compact size, high efficiency, and excellent thermal performance. Its working principle is based on a current-regulated LED string in series with a low-dropout voltage regulator driver, which controls the operating frequency and dimming effect of the LED string.
