• LED – Circuit Board Indicators
A Light-emitting diode (LED) is a semiconductor light source that emits visible light when an electric current passes through it. LED indicators are typically used in circuit boards to indicate the status of a system or process. When a switch is turned on, an LED turns on and provides a visual indication that the switch has been activated. The advantage of LED indicators is that they use very little power and they have a long lifetime. LED indicators are typically available in a variety of sizes and colors, making them an ideal choice for circuit board indication.
• LED Arrays
LED arrays are organized collections of LEDs used to create images or symbols. LED arrays can be used to indicate different statuses, as in the case of LED indicators, or to provide visual information about a process or system. LED arrays are typically composed of multiple LED’s arranged in a row or matrix. Depending on the requirements, LED arrays can be made from different materials and configured in different ways.
• LED Light Bars
LED light bars are groups of LEDs arranged in a long bar. They are often used in automotive applications such as turn signals, brake lights, and running lights, as well as for roadside emergency warning systems. LED light bars are made up of multiple color LEDs that are arranged in a linear pattern. This creates a bright, uniform light suitable for a variety of applications.
• LED Bar Graphs
LED bar graphs are composed of multiple discrete LEDs arranged in a rectangular or cross-shaped pattern. These LEDs are used to give a visual indication of the magnitude of a signal in terms of brightness. The brighter the LED, the higher the magnitude of the signal. LED bar graphs are commonly used in audio visual equipment, medical monitoring equipment, and process control systems.
