Solid State Lighting (SSL) Connectors are electrical components designed to establish reliable interconnections between LED lighting systems and power sources. As critical elements in modern LED lighting architecture, these connectors enable efficient power transmission, signal control, and modular system design. Their importance stems from the growing demand for energy-efficient lighting solutions, with SSL connectors ensuring durability, scalability, and compliance with safety standards in applications ranging from residential to industrial environments.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Wire-to-Board Connectors | Direct PCB mounting, compact design, 0.5-5A current rating | LED strip lighting, retrofit lamps |
| Board-to-Board Connectors | Stackable design, 1-10A capacity, low insertion force | Modular LED panels, downlights |
| Wire-to-Wire Connectors | Quick-disconnect capability, IP20-IP67 ratings | Outdoor LED fixtures, emergency lighting |
| Circular Connectors | 360 rotation, multi-pole configurations, >10A | High-power floodlights, stage lighting |
