Component Identification

Label Component Type Details
DB Bridge Rectifier Likely a DB107S or DB207S (1A-2A, 1000V) that converts AC input to DC.
U1 LED Driver IC A constant-current controller that regulates power to the LEDs.
L1 Inductor Labeled “YJ-152,” typically a power inductor for filtering or voltage regulation.
F1 Fuse A wire-wound or cylindrical safety component to protect against surges.
C1, C2 Capacitors Electrolytic capacitors used for smoothing the DC voltage.
RS1 Current Sense Resistor Used by the driver IC (U1) to monitor and limit the current through the LEDs.

 

 

 

Application & Safety

This module is intended for DIY electronics, hobby kits, or as raw material for manufacturing LED bulbs. Because it connects directly to AC mains (180-240V), it must be handled with extreme caution during testing to avoid electrical shock.

This board is a 20-Watt Alpha Driver-on-Board (DOB) LED MCPCB. It is a “Direct On Board” circuit, meaning the AC-to-DC conversion and LED driver components are integrated onto the same metal-core PCB (MCPCB) as the light-emitting diodes, typically for use in 20W LED bulbs.

Key Specifications
  • Power Rating: 20 Watts.
  • LED Type: 18 SMD 2835 LEDs (2.8mm x 3.5mm package).
  • Input Voltage: 180V to 240V AC.
  • Color Temperature: Cool White (typically 6500K).
  • Board Construction: 1.2mm to 1.6mm thick Aluminum Metal Core PCB for heat dissipation.
Weight .5 kg
Dimensions 3 × 3 × 1 m
