Main Features
Acrylic Light Guide
A precision-machined acrylic panel distributes LED light evenly across the entire illuminated logo, producing a clean and premium appearance.
Uniform Diffused Lighting
Special light diffusion techniques eliminate hotspots and provide smooth illumination across the complete branding area.
USB-Powered Operation
The module operates directly from the television’s USB port without requiring an external power adapter.
Integrated DC Boost Converter
A custom electronic board converts the available 5V USB supply into 12V required by the LED lighting system while maintaining high efficiency.
Automatic Operation
The illumination automatically turns on and off together with the television through the USB power source.
Compact Electronics
The custom PCB integrates:
- DC Boost Converter
- LED Driver
- Power Filtering
