LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs

LEDs have become an integral part of modern electronics and are widely used in a variety of applications. LED circuit board indicators, arrays, light bars, and bar graphs are all common LED devices used in electronic equipment. In this article, we will take a look at the application field and working principle of a common LED device, the 553-0111.The 553-0111 is a single-colour LED circuit board indicator which combines the advantages of LED technology and conventional diode indication into one device. It is widely used in military, aerospace, industrial and energy controls, as well as medical instrumentation and signal systems. Due to its unique design and components, the 553-0111 provides ultra-high brightness and precise current regulation, making it ideal for these applications.The 553-0111 consists of an encapsulated PCB or “skull” containing an LED die and a base resistor, as well as a separate dielectric film. The dielectric film is designed to be used as a non-conductive and light reflecting surface. The 553-0111 also contains a high efficiency power supply which provides a precise current for the LED, ensuring consistent performance and reliable operation.The 553-0111’s LED die is connected in series with the base resistor and the two form a constant-current circuit. When a voltage is applied, the LED’s current is limited by the base resistor, thus ensuring a consistent current over the entire voltage range. The dielectric film acts as a reflector, which allows the LED’s light to be focused or directed to the desired area.The main advantage of the 553-0111 is its combination of high brightness and precise current regulation, which makes it an ideal choice for applications that require precise indication, such as military and aerospace systems. Additionally, its compact design and low power consumption make it a cost-effective and reliable solution for many applications.In summary, the 553-0111 is a single-color LED circuit board indicator which is widely used in military, aerospace, industrial and energy controls, as well as medical instrumentation and signal systems. Its combination of high brightness and precise current regulation make it an ideal choice for applications that require precise indication, and its low power consumption and compact design make it a cost-effective and reliable solution.
