WP1384AL/ID Optoelectronics

Introduction: LED technology has been a tremendous advancement offering significant advantages in terms of lighting applications. Among its various applications, some of the most common are: circuit board indicators, arrays, light bars, and bar graphs. This article will focus on one such application, namely the WP1384AL/ID from TOPLEDss, and examine its field of use and working principle. WP1384AL/ID: The WP1384AL/ID is a LED light bar equipped with a precise control circuit to adjust the current intensity in order to meet various requirements. It is specifically designed as a LED lighting indicator for industrial and commercial applications, such as traffic signal systems and warning systems. The WP1384AL/ID utilizes a programmed microcontroller to precisely adjust the current intensity of each LED in the bar in order to achieve a brighter illumination and the desired lighting effects. For example, it can be programmed to produce a blinking or flashing pattern, allowing it to be more visible than other LED indicators. Working Principle: The WP1384AL/ID works by controlling the current of each individual LED, allowing it to adjust the overall lighting state of the light bar. It is an effective solution, as each LED can be programmed to produce different lighting intensity, creating an animated display effect. Additionally, the device utilizes a constant current circuit design to ensure that a consistent, optimal lighting intensity is achieved throughout the duration of the device. The programming of the device is performed using the included programming software, or through the embedded microcontroller. Through the programming language, users can define the overall lighting state of each individual LED, including brightness level, duration, pulse sequence and color selection. The device also incorporates a thermistor, which helps prevent overheating by automatically adjusting the current levels as needed.Conclusion: The WP1384AL/ID is an ideal solution for applications requiring a reliable and accurate lighting indicator. By utilizing a microcontroller for precise current adjustment and a thermistor to help prevent overheating, the device can be easily programmed to produce highly visible lighting animations. This makes it ideal for use in a number of applications, including traffic signal systems and warning systems.
