LED Indication - Discrete

LEDs, or light-emitting diodes, provide a discrete indication of status. LED indicators use light as an indication of condition and are an important part of a complete industrial control system. LEDs are more visible than lamps, and are much more economical, reliable, and long lasting.The QTLP321CY is a 3mm thru-hole LED device. It is constructed of yellow Gallium Arsenide Phosphide on Gallium Phosphide (GaAsP/GaP) grown on a Gallium Phosphide substrates. It is a very efficient light source, with a luminous intensities typically ranging from 4 to 15 mcd at operating currents from 5 to 10 mA.The QTLP321CY is suitable for a wide range of applications and is particularly useful for providing a discrete indication in industrial, domestic, and commercial equipment. It has a flexible power supply range and can operate on DC and AC voltages. It is also very easy to install and operate.The working principle of the QTLP321CY is based on the PN junction. In this type of device, the p-type and n-type regions of the semiconductor material are connected in order to form a single block. When a voltage is applied to this p-n junction, it causes the electrons to move in one direction and the holes to move in the other direction. As a result of this flow of charge, a current is produced and the electrons recombine with the holes. This creates an electric field within the device. When electrons in the excited state drop back to the ground state, they emit a visible light. The color of the light depends upon the materials used in creating the PN junction.The QTLP321CY also has good thermal and optical characteristics, making it suitable for use in a wide range of conditions. It is rated for temperatures up to 105°C and has a luminous flux of 4 msc at 20°C. It is also resistant to shock and vibration, making it suitable for industrial applications. In addition, it has a low forward voltage drop and low capacitance, providing improved efficiency and reduced power consumption.The QTLP321CY offers a wide ambient temperature range and low power consumption. It is also easy to install and use. It can be used to provide a discrete indication of status in a variety of applications, ranging from domestic to industrial equipment. It is an efficient, long-lasting and reliable light-emitting diode, with good optical and thermal characteristics.
