LED Drivers

1. Overview

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.

2. Main Types & Functional Classification

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

3. Structure & Components

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

4. Key Technical Specifications

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

5. Application Fields

Architectural Lighting: Bridge/tower accent lighting
Industrial: High-bay warehouse lighting systems
Automotive: Adaptive driving beam (ADB) headlights
Smart Cities: IoT-enabled streetlight networks
Medical: Surgical operating room lighting

6. Leading Manufacturers & Products

Manufacturer	Product Series	Key Features
Philips Xitanium	XF2G121	105W, 0-10V dimming, 5-year warranty
Osram OT	OTi DALI	DALI-2 certified, 16A output
Mean Well	HBL-40A	40W constant current, IP67 rating

7. Selection Guidelines

Match output current/voltage to LED specifications
Verify dimming compatibility (e.g., phase-cut vs. 0-10V)
Check environmental ratings (IP, temperature)
Confirm safety certifications (UL, CE, DLC)
Calculate system lifetime vs. driver MTBF

8. Industry Trends
