LED Indication - Discrete is an important part of lighting and display applications, which often use discrete components to provide a simple and reliable solution to indicate the status of equipment. The QBLP1515B-RGBA is one of the offerings in the family of LED indicators, and its application field and working principle is discussed in this article.

Description

The QBLP1515B-RGBA from Quanxing Technology is a low profile, surface mount discrete LED indicator. It offers wide viewing angle and uniform brightness, making it ideal for panel-mounted status indication. The device is offered in four color options - Red, Green, Amber, and Blue. It has an extended maintenance-free lifetime of up to 50,000 hours.

Features

• Low Profile
• Wide Viewing Angle
• High Luminous Intensity
• Constant Color Temperature
• Excellent Color Control
• Long Maintenance-Free Lifetime

Application Field

The QBLP1515B-RGBA LED indicator is suitable for a wide range of applications that require a discrete and reliable indicator source. These include, but are not limited to, industrial equipment control and status indication, audio/visual equipment control and status indication, home appliance control, automotive lighting and control systems, emergency lighting, navigation systems and indicators, and general lighting applications.

Working Principle

The QBLP1515B-RGBA LED indicator works by using an internal light source to emit light when power is supplied. The internal light source consists of several individual Light Emitting Diodes (LEDs) of the same color. The LEDs are arranged in a horizontal line, with each LED having its own contacts for power and ground. When power is supplied, it causes a current to flow through the LEDs, resulting in illumination. The brightness of the illumination is controlled by the amount of power supplied to the LEDs.

The QBLP1515B-RGBA LED indicator has a built-in regulator circuit which helps to minimize the effect of temperature and supply voltage fluctuations on the brightness of the illumination. This helps to ensure reliable operation even in extreme environments.

Conclusion

The QBLP1515B-RGBA LED indicator from Quanxing Technology is a low profile, surface mount discrete LED indicator that is suitable for a wide range of applications that require a discrete and reliable indicator source. With its wide viewing angle, high luminous intensity, excellent color control, and extended maintenance-free lifetime, the QBLP1515B-RGBA LED indicator is an ideal choice for status and control indications.
