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

1. Overview

Light Emitting Diodes (LEDs) are semiconductor devices that convert electrical energy into light through electroluminescence. This product category includes indicators, arrays, light bars, and bar graphs designed for circuit board integration. LEDs serve critical roles in modern electronics for status indication, data visualization, and illumination. Their advantages include low power consumption, long lifespan, and compact form factors.

2. Main Types and Functional Classification

TypeFunctional FeaturesApplication Examples
IndicatorsSingle/dual-color point-source lighting for status indicationPower switches, network routers, medical device panels
ArraysMatrix configurations for alphanumeric/symbol displaySeven-segment displays, dot matrix modules
Light BarsLinear arrangements for directional lighting/brightness zonesAudio level meters, industrial control panels
Bar GraphsSegmented columns for quantitative visual representationBattery level indicators, sensor data visualization

3. Structure and Components

Typical LED components include:

  • Die: Gallium Nitride (GaN) or Indium Gallium Aluminum Phosphide (InGaAlP) semiconductor chips
  • Substrate: FR4 or metal-core PCB for thermal management
  • Encapsulation: Epoxy resin with diffused/optical lens structures
  • Driver Circuitry: Current-limiting resistors or PWM control ICs

4. Key Technical Specifications
