Light Emitting Diodes (LEDs) have been increasingly popular in the industrial, commercial and consumer markets due to their long life and energy efficiency. The HLMP-K155 LED is a discrete LED specifically designed for a wide range of automotive, consumer and commercial applications, including signal indicators, backlighting, instrument panels, car navigation systems, and decorative lighting. In this article, we will look at the application field and working principle of the HLMP-K155 LED.

Application Field of HLMP-K155 LED

The HLMP-K155 LED is a 5mm discrete LED that provides a consistent performance and reliable operation. Available in red, orange and yellow, the HLMP-K155 is ideal for a wide range of automotive, consumer and commercial applications. It is suitable for high-intensity signal indicators, backlighting, instrument panels, car navigation systems, and decorative lighting. It is also suitable for applications requiring high levels of intensity, such as signs and displays, aviation applications, video and audio indicators, electronics instruments, and military applications.

The HLMP-K155 is designed to provide a long life and energy efficiency. Its low current consumption and high luminous efficacy make it ideal for battery powered applications. Its reduced thermal resistance and high reliability allow for a direct mount solution. The LED has a wide viewing angle of 120° and a low thermal resistance of 1.5K/W, and its package has been designed for use in tight spaces. The LED is also ESD protected and offers excellent compatibility with a wide range of bases and housings.

Working Principle of HLMP-K155 LED

The HLMP-K155 LED is a light-emitting diode (LED). It is a type of diode, an electronic component that permits the flow of electrical current only in one direction. An LED is a two-terminal device and is usually constructed from two semiconductors sandwiched together. In the HLMP-K155, the anode and cathode are formed in a semiconductor p-n junction (or "diode-junction"). When electrons flow across this p-n junction, they recombine with positively charged holes, releasing energy in the form of light.

The HLMP-K155 LED produces light when an electric current passes through the diode-junction. When powered by an external voltage, the current-carrying electrons will be pushed into the p-n junction, where they will become trapped. As the current builds up, more electrons are pushed into the junction, causing the voltage to increase and activating the diode-junction. As the voltage continues to increase, the electrons recombine with the positively-charged holes, releasing energy in the form of light.

The light produced by the HLMP-K155 LED is in the visible spectrum and can be observed as a distinct color, depending on the type of LED used. Red LEDs produce a reddish-orange light, orange LEDs produce a yellow-orange light, and yellow LEDs produce a yellow-green light. The intensity (brightness) of the visible light generated depends on the current passing through the LED.

Conclusion

The HLMP-K155 LED is a discrete LED designed for a wide range of automotive, consumer and commercial applications, including signal indicators, backlighting, instrument panels, car navigation systems, and decorative lighting. It is suitable for applications requiring high levels of intensity, such as signs and displays, aviation applications, video and audio indicators, electronics instruments, and military applications. The HLMP-K155 produces light when an electric current passes through the diode-junction, and the intensity (i.e., brightness) of the light generated depends on the current passing through the LED.
