LED indicators are light-emitting devices (LEDs) used to indicate the current status of a system or process. LED device selection comes down to a few components, including viewing angle, lens materials, and LED types, size, voltage and temperature environmental effect.

The QBLP613-RIG is a single-colour red LED indicator that is fitted inside an illuminated screw shell (ISS) unit, which provides an efficient and cost-effective solution to a variety of visual indications. It is ideally used in electromechanical equipment, professional audio, lighting and instrumentation applications.

Application Field and Working Principle

Within its widely used application range, the QBLP613-RIG is particularly suitable for audio equipment, medical and laboratory equipment, industrial test and control panels, and domestic appliances. Its robust construction allows it to withstand the harshest environments, making it ideal for aerospace and defence applications.

The QBLP613-RIG’s front face has a unique design with a matt black split-glass or clear acrylic lens. This lens is sealed against the LED body and provides an efficient light output, while a stainless steel bezel around the edge of the lens provides mechanical protection. The working principle of the LED is based on the p-n diode principle, which allows current to flow in only one direction when a voltage is applied to the LED. When a voltage is applied to a LED, electrons and holes combine in the p-n junction and release energy in the form of light.

The typical forward voltage of a red LED indicator is around 2 volts, with a power dissipation of 65mW, a forward current of 20mA and an optical power of 2.2mcd. In addition, the LED indicator has a 50 degree viewing angle, an operating temperature of -20°C to +85°C and is moisture and dust proofed, to IP67 standards.

The LED indicator is available in a range of mounting fixings, including metal carrier bases, angled plastic bases and mounting pliers, and can be used with a range of wire press or twin terminal blocks. The metal counter and fixing cover plates provide easy installation, making the QBLP613-RIG ideal for use in indicators and control panels.

In terms of the overall brightness of the LED indicator, the QBLP613-RIG delivers a consistent light output and is designed to provide excellent illumination, even in poorly lit areas. In addition, the LED indicator is designed to be highly reliable and effective, making it a popular choice for many audio and electrical applications.

In summary, the QBLP613-RIG is a robust single-colour red LED indicator that is ideally used in a variety of visual indication applications. Its unique design and high level of reliability make it one of the most popular LEDs for many audio equipment, medical and laboratory equipment, and industrial test and control panels.
