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.
| Type | Functional Features | Application Examples |
|---|---|---|
| Indicators | Single/dual-color point-source lighting for status indication | Power switches, network routers, medical device panels |
| Arrays | Matrix configurations for alphanumeric/symbol display | Seven-segment displays, dot matrix modules |
| Light Bars | Linear arrangements for directional lighting/brightness zones | Audio level meters, industrial control panels |
| Bar Graphs | Segmented columns for quantitative visual representation | Battery level indicators, sensor data visualization |
Typical LED components include:
| Parameter | Description | Importance |
|---|---|---|
| Luminous Intensity | 0.1-100 cd/m range | Determines visibility in various lighting conditions |
| Wavelength | 400-700 nm (visible spectrum) | Defines color output accuracy |
| Forward Current | 2-30 mA typical | Impacts brightness and longevity |
| Viewing Angle | 5-120 depending on lens design | Dictates light distribution pattern |
| MTBF | 50,000-100,000 hours | System reliability prediction |
Key industries include:
| Manufacturer | Product Series | Key Features |
|---|---|---|
| Cree | XLamp XR | High-brightness automotive indicators |
| OSRAM | LED Line | Programmable RGB light bars |
| Nichia | NSPWR70CSS | Ultra-compact bar graph displays |
| Everlight | DLW-5xxx | Waterproof array modules |
