3BC-R/Y-F Application Field and Working Principle

The 3BC-R/Y-F LED (Light-Emitting Diode) Indication Lamp is applied on a variety of machines, instruments and apparatus for indication, pointing, lighting and traffic control. It is especially suitable for 5V DC and 24V DC circuits, and is compatible with all types of diodes, transistors and integrated circuits.

The 3BC-R/Y-F LED Indication Lamp is a two-terminal highlighted device with a red/yellow radial lead. The efficient design, combined with the high-quality materials used to make the lamp, ensures lasting performance and exceptional clarity even if subjected to continuous use. Due to its UL, VDE and ENEC approvals, the 3BC-R/Y-F is guaranteed to operate safely until the end of its operational life.

The 3BC-R/Y-F is available in three colours: Red, Yellow and Green. Each colour has a specific voltage and current rating, so it is important to check that the correct type is selected. In general, red and yellow colours require less power than green and white LEDs. In addition, the 3BC-R/Y-F is suitable for use in intermittent applications, as it can withstand a surge of up to two times its rated current for up to 40 to 60 seconds.

The 3BC-R/Y-F LED indication lamp features a wide viewing angle of 120 degrees, allowing it to be viewed from anywhere, no matter its orientation. The long-term stability and reliability of the lamp are ensured through the use of a re-flowable soldering process that effectively seals the leads and ensures that the LEDs and their associated components are firmly attached to their contacts.

The working principle of the 3BC-R/Y-F is based on the point contact of n- and p-type semiconductor materials. An electric current flows across the junction and recombines with electrons and holes to form light photons. As the forward voltage is applied, the current increases until it reaches its rated forward current. The rate of current at which the voltage changes is governed by the resistance of the semiconductor material, not by the type of device.

The 3BC-R/Y-F is a versatile device that can be used for a variety of applications. It is suitable for use in dynamic and static state devices such as indicators, switches, relays and alarms. The 3BC-R/Y-F is also a reliable source of illumination for product displays and lighting applications. Its long-term stability, combined with its wide viewing angle and low power consumption make it suitable for a wide range of applications.
