LED Indication - Discrete components represent the simplest visual variants for lighting up objects. The HLMP-EL15-TWKDD is a discrete LED device used in circuit boards that has a wide range of application possibilities. This article explains the application field of the particular device and its working principle.

Design: The HLMP-EL15-TWKDD features a simple design, which is composed of a PPA LED encapsulated in silicone. The LED itself is mounted inside an open-top plastic case, which offers protection from physical damage as well as protection from environmental degradation. The device has 4 pins and two mounting holes, making it easy to mount on a printed circuit board (PCB). The LED requires a voltage of 3.3V, and is capable of emitting light in a variety of colors, ranging from amber to red. This product offers high peak wavelength, low thermal resistance, and long life expectancy.

Application Field: The chief application field of the HLMP-EL15-TWKDD lies in providing discrete LED indication on circuit boards. The LED can be used to monitor a variety of BMS parameters and can be used to indicate the presence of a signal, power, and data. Since the LED is bright and has a wide color range, it can be used in a multitude of applications, including on/off indicators, power indicators and status indicators. Furthermore, since the LED does not require much power, it can also be used for board level indication in battery operated systems.

Working Principle: The working principle of the HLMP-EL15-TWKDD relies on the principle of changing the current passed through the LED to control its output intensity. The current is controlled by varying the voltage across the device. This is typically done via pulse width modulation (PWM). A PWM circuit can vary the voltage passed through the LED, varying the frequency and amplitude that the LED shines. This can be used to visual indicate a variety of values, such as status and power.

Conclusion: The HLMP-EL15-TWKDD is a discrete LED indicator, designed for use in circuit boards. It features a simple design, with 4 pins and two mounting holes, and a wide variety of colors. Its chief application lies in providing board level indication and status monitoring. The device works by varying the current passed through it via pulse width modulation (PWM).
