LEDs are used in countless applications from simple indicators and displays to complex light-reactive systems and portable data terminals. The XQL2LUR11D is an example of a comparatively simple yet effective LED circuit board designed for function and durability in a small form factor.

The XQL2LUR11D is a compact, low-cost, single-LED circuit board solution that can easily fit into a standard breadboard or PCB assembly. With its low-power 5Vdc operation and its 4-pin, ribbon-style connector, the XQL2LUR11D is ideal for indicators, arrays, light bars, bar graphs, and other flat-panel applications such as LCDs.

Applications

The XQL2LUR11D LED circuit board is designed for a wide range of applications, including automotive, industrial, and consumer. Automotive applications include cluster and backlighting, dashboard and steering wheel controls, marker lights, warning, and door locks. Industrial applications include assembly line indicators, automation, and power supply status. For consumer applications, it can be used to light up a wide range of products, from speakers and entertainment systems to medical devices and home security monitors.

Working Principle

The XQL2LUR11D LED circuit board operates on a simple principle: When power is supplied, an LED is illuminated. This is accomplished through two main components, the LED and the integrated circuit (IC).

The LED is the light-emitting component of the circuit board. It produces light in response to an electrical current and is usually mounted on a heat sink. The current can be provided from an external source, such as a DC power supply or battery, or it can be generated within the IC using a step-up voltage converter.

The IC is the controlling component of the circuit board. It regulates the current flow to the LED and can be programmed to vary the brightness and color of the light emitted. Using PWM (pulse-width modulation) technology, the IC can precisely control the brightness of the LED, resulting in a wide range of illumination intensity levels, from dim to bright.

The XQL2LUR11D LED circuit board is also designed with a built-in temperature sensor that helps to protect the LED and keep it running at an optimal temperature. Furthermore, the XQL2LUR11D is capable of operating in a wide range of temperatures, from -30°C to +85°C.

The XQL2LUR11D LED circuit board is the perfect choice for any applications requiring a reliable, low-cost indicator with excellent performance.
