LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs

The HLMP47409MP7 is a high performance surface mount yellow LED supplied in a GIF 67 package that allows for small profile designs. Designed for automated assembly processes, this LED offers excellent reliability and consistently high performance with a maximum viewing angle of 15°. It is designed specifically with applications such as level indicators and power on indicators in mind. In addition, the wide viewing angle and high radiant flux output allows the HLMP47409MP7 to be well suited for backlighting and other display applications where high efficiency and wide viewing angles are required.

Applications

The HLMP47409MP7 LED is designed for level indicators and power on indicators, as well as other applications in the automotive, industrial and communication fields. Its wide viewing angle and high radiant flux output makes it ideal for display backlighting applications. This LED is also suitable for lighted control switches, as well as warning lights, indicator lamps and general illumination.

Working Principle

The principal of operation for the HLMP47409MP7 LED is quite simple. A p-n junction diode is created by combining two different pieces of semiconductor material, one each p-type and n-type. When the LED is provided with a forward bias voltage (typically 2.8 to 4 volts), current passes through the junction, releasing light energy in the process.

The junction temperature of the diode also affects the wavelength of light produced by the LED. As the temperature of the junction increases, the wavelength of the light output decreases. This is why the color of an LED may differ at different temperatures. Alternately, this is why it is important to keep the junction temperature of the LED in check while operating; too much heat and the wavelength of the emitted light will be affected.

The intensity of the emitted light is dependent on the forward bias current of the diode: a higher current causes the LED to produce more light. Therefore, when using the HLMP47409MP7 LED as a level indicator, one must ensure that the design incorporates a method of regulating the forward bias current so that the LED emits a consistent light output.

Advantages

The HLMP47409MP7 LED offers a few advantages over other LEDs. Its surface mount design allows for a low profile, enabling it to be used in applications where space is at a premium. Its wide viewing angle and high radiant flux output make it perfect for backlighting and display applications, while its integrated lens minimizes the light loss associated with viewing angle. Additionally, its low forward voltage requirement makes it well suited for low-voltage applications.

Conclusion

The HLMP47409MP7 LED is a reliable, high performance LED designed specifically for level indicators and power on indicators, as well as other applications in the automotive, industrial and communication fields. It is well suited for backlighting and display applications due to its wide viewing angle and high radiant flux output, and its low forward bias voltage makes it perfect for low-voltage applications. With its surface mount design, the HLMP47409MP7 LED is an excellent choice for applications requiring a low profile design.
