HLMP-3950

HLMP-3950 LED Indication - Discrete

The HLMP-3950 is a range of long luminous intensity and small profile LEDs from the HMLP-3XXX product family that have been designed for applications that demand high performance LED indicators that consume low power and have a wide operating temperature range. The HLMP-3950 comprises two distinct components – an LED and an associated color housing – and is accessible in a variety of color and intensity combinations. The abbreviated product name is HLMP-3950L.

The HLMP-3950 utilizes a water clear device mounted on top of the gold-plated leadframe, enabling the visible light to be emitted with a wide viewing angle that covers over 160°. The transparent package is specifically designed to provide unparalleled light retention, likewise making sure low light loss throughout the device’s lifetime. The unit is well-suited for various types of industrial, consumer, and telecommunication applications that expect long life expectancy, reliable optical performance, and low power consumption.

Applications

With an operating temperature range from -20 to +100 °C, the HLMP-3950 LED is ideally suited for use in harsh environmental conditions. The LED can be used in various industrial applications such as switches and indicators, control panels, appliance meters, CT units, and supervisory signaling. It is also widely used in consumer and telecommunication applications such as audio visual alarms, touch panels, TV remotes, cellular phones, and many others. It is suitable for multiple voltage requirements, ranging from 2.2 to 3.7 volts.

Working Principle

The HLMP-3950 LED provides illuminated indication when operating voltage is applied. Depending on the shape and output power, the LED may provide constant illumination or brightness variation. It consists of a small semiconductor junction enclosed within a package that consists of a windowed surface that contains a encapsulated semiconductor. When electrical voltage is applied through the leads, electrons and holes recombine in the junction to produce light.

The physical construction of the HLMP-3950 LED\'s package contains a chip, which is either a surface-mount device (SMD) or a through-hole type, to provide constant or variable illumination and a surface-mount (SMD) or through-hole lens and housing to provide protection and reduce power consumption. The chip, installed inside the package and suspended in a solution, is made of a semiconductor material such as silicone, germanium, and others that can easily allow light emission. The heat generated from the driver pushing electrical energy through the junction is dissipated by a heat sink and/or fan.

Conclusion

The HLMP-3950 is a high performance, low power consumption and wide operating temperature range LED. It is an excellent choice for various types of industrial, consumer, and telecommunication applications as its long life expectancy, reliable optical performance and low power consumption ensures that it can be used for a wide range of applications. Its operating temperature range from -20 to +100 °C also makes it suitable for harsh environmental conditions.
