Product Description
The 9 Watt 20 LEDs AC DOB LED Circular PCB is a high-efficiency lighting module designed for the manufacturing and repair of standard LED bulbs. This module utilizes Driver-on-Board (DOB) technology, which integrates the AC-to-DC conversion and constant-current regulation circuitry directly onto the aluminum substrate. By eliminating the need for a bulky external plastic-cased driver, this PCB allows for a more compact bulb design and simplified assembly. Featuring 20 high-performance SMD LEDs arranged in a circular pattern, it provides a powerful, uniform cool white light output with excellent thermal management properties, making it an essential component for energy-saving home and industrial lighting.
Key Features
Integrated Driver Technology: No external driver required; connects directly to the 230V AC mains, reducing material costs and assembly time.
High-Density LED Array: 20 SMD LEDs ensure high lumen output and wide-angle light distribution for better room coverage.
Aluminum Core PCB (MCPCB): Built on a high-thermal-conductivity aluminum base that effectively draws heat away from the LEDs, significantly extending their operational lifespan.
Compact Circular Design: Standard diameter fits perfectly into most 9W LED bulb housings (B22/E27 type).
Flicker-Free Performance: Integrated IC regulates current to provide stable illumination, reducing eye strain and improving video recording quality under the light.
