As the heart of electronic products, the circuit board plays a vital role in the normal operation of electronic equipment. In this article, we will delve into the world of Circuit Board Indicator LED, exploring its history, types, applications, and future trends.

History of Circuit Board Indicator LED

The invention of the LED dates back to 1907, when the American physicist Henry Joseph Round first discovered that certain materials could emit light when an electric current passed through them. However, it was not until the 1960s that the LED was first used in practical applications. Since then, the technology has been constantly improving, and it has become an indispensable part of electronic products.

In the early days, LED indicators were mainly used in calculators and other small electronic devices. With the development of technology, LED indicators have gradually expanded their application fields, becoming a common component in various electronic products such as computers, mobile phones, and household appliances.

Types of Circuit Board Indicator LED

According to the light color, the Circuit Board Indicator LED can be divided into red, green, blue, yellow, and white, among others. Different colors represent different meanings. For example, red LEDs are often used to indicate an alarm or an error state, while green LEDs are used to indicate normal operation.
