PCB LED (Light Emitting Diode) indicators are light-producing components which serve as lighting sources on aluminium printed circuit boards (PCBs). These indicators have paired-up charge carriers (diodes) located in a semiconductor to generate light without producing too much heat.
What are PCB LED indicators used for?
PCB LED indicators are energy efficient, environmentally friendly and resistant to dust and moisture. They have improved heat transferring (diffusion) attributes. This makes them suitable for use in computer machinery like power devices, drives and central processing units, helping to keep heat away from sensitive parts.
In the automotive sector, these indicators are used in headlights, brake lights and for warning light purposes.
The medical industry also makes use of PCB LED indicators in the form of warning lights. These safety measures ensure that life-saving equipment is working correctly.
Types of PCB LED Indicators
Two main types of PCB LED indicators are available:
Single point or block indicators can be used on multiple surfaces and in a variety of product applications.
Integral or surface mounted PCB LED indicators can be attached to the same connector tail of the switch which increase ease of installation and usage.
