LED drivers are electronic devices that regulate power to LED light sources. They convert AC mains voltage to DC current/voltage required by LEDs, ensuring stable light output and longevity. Modern lighting systems rely on LED drivers for energy efficiency (up to 95% efficiency), thermal management, and dimming control in applications ranging from consumer electronics to industrial lighting.
| Type | Function Features | Application Examples |
|---|---|---|
| Constant Current (CC) | Provides fixed output current (e.g., 350mA/700mA), adjustable voltage range | High-power LED streetlights, architectural lighting |
| Constant Voltage (CV) | Maintains fixed output voltage (e.g., 12V/24V DC), variable current | LED strips, downlights, backlighting systems |
| Dimmable Drivers | Supports 0-10V/PWM/digital dimming protocols | Smart home lighting, theater stage lighting |
| Offline Drivers | Direct AC mains input without external transformer | Industrial LED floodlights, retrofit bulbs |
Typical construction includes: - Die-cast aluminum housing with IP65+ protection - Input EMI filter and bridge rectifier - Power factor correction (PFC) circuit - Isolated flyback/forward converter topology - Output current sensing resistor network - Thermal shutdown and overvoltage protection (OVP) circuits - Optional DALI/DMX communication interfaces
| Parameter | Typical Range | Significance |
|---|---|---|
| Input Voltage | 90-305V AC / 12-48V DC | Determines global compatibility |
| Output Current | 100mA-2.5A | Matches LED string requirements |
| Efficiency | 85-96% | Impacts energy consumption |
| Power Factor | 0.85-0.99 | Reduces grid reactive power |
| Operating Temp | -40 C to +85 C | Environmental reliability |
