LEDs are a type of light-emitting diode, which is composed of a semiconductor material. It is a quite efficient electrical-to-optical conversion device, characterized by wide voltage range, fast switching speed, long-term stability and high brightness. LEDs are widely used in many fields. The application field of WP710A10SRC/D, a kind of LED Indicator-Discrete, is discussed in this article and its working principle is also presented.

Application Field of WP710A10SRC/D

WP710A10SRC/D is the environmentally friendly, advanced LED Indicator, which has been widely used in various fields. It is particularly suitable for applications where long term reliability, excellent performance and high luminous power are essential, such as portable electronic products, signal indicators, automotive instrument panel block, electrical and electronic equipment, etc. WP710A10SRC/D is also commonly used in harsh environments, where it needs to withstand high operating and storage temperatures and high humidity.

Working Principle of WP710A10SRC/D

WP710A10SRC/D LED indicator operates based on the principle of light-emitting diode. A diode is an electronic component, which is formed due to the p-n junction of two semiconductor materials. When a certain direct electric current is applied to the diode, the electrons in the p-layer and holes in the n-layer will move, forming a recombination region at the edge of p-layer and n-layer. The electrons release energy and photons will be emitted in the form of light. WP710A10SRC/D is mainly made of a high brightness gallium-arsenide phosphide (GaAsP) semiconductor material and a transparent diode case.

WP710A10SRC/D transilluminates the lens with a very bright LED. On the one side of the lens, an IC module is integrated. This IC module contains the driving circuitry, pulse width modulation (PWM), which is used for controlling the brightness of the LED. PWM is a modulation technique, which is used to control the average power of a signal by varying the width of the pulses. The constant current drive circuit reduces the power drop across the LED and improves LED brightness by avoiding any fluctuations. The LED also features high luminous intensity with small size and low power consumption.

WP710A10SRC/D can operate in two modes, i.e. static or flashing mode. In static mode, the IC is turned off, the LED is directly connected to anode of the driving power supply, and the resistor is connected between the anode and the cathode of the LED. In this way, a forward voltage is applied to the LED to produce a static light. In flashing mode, the IC is being turned on and a digital signal is sent to the LED, making it flicker. Flashing LEDs are especially suitable for applications requiring attention-drawing effect.

WP710A10SRC/D LED Indicator-Discrete is a reliable and cost-effective solution for applications requiring long-term stability, excellent performance and high luminous power. The device operates based on the principle of light-emitting diode and can be used in static or flashing modes, which is accessible for applications requiring attention-drawing effect.
