Light LED PCBA Overview

Introduction

The Light LED PCBA is a compact and efficient printed circuit board assembly designed for LED lighting applications. This PCBA features 1-2 layers of conductive material, making it suitable for simpler circuit designs while maintaining high performance and reliability.

Définition

A Light LED PCBA refers to a printed circuit board assembly that incorporates surface mount technology (CMS) or through-hole technology (Tht) components specifically for LED lighting applications. The PCBA includes all necessary electronic components soldered onto the PCB, ready for integration into an LED lighting system.

Principe de fonctionnement

The working principle of a Light LED PCBA involves using conductive copper traces on a non-conductive substrate to create electrical pathways. These pathways connect various electronic components such as LEDs, résistances, and capacitors. When electrical current flows through these pathways, it powers the LEDs, causing them to emit light.
