Patents by Inventor Xiaodeng Chen

Xiaodeng Chen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Programmable light apparatus
    Patent number: 11330694
    Abstract: A programmable light apparatus includes a LED module and a driver. The driver has a current adjustable circuit that supports multiple types of LED modules. By sending a programming signal to a wireless circuit of the driver, the current adjustable circuit determines a correct setting to provide a necessary driving current to a corresponding LED module.

  • LED driving circuit
    Patent number: 11284487
    Abstract: A LED driving circuit includes a DALI module, a linear voltage luminance adjusting module, a DIP luminance adjusting module, a control module, a power source, a constant current driving module and an output module. The DALI module generates a PWM signal. The linear voltage luminance adjusting module generates a second PWM signal. The DIP luminance adjusting module generates a switch signal. The control module generates a drive PWM signal using the first PWM signal, the second PWM signal and the switch signal. The power source provides power. The constant current driving module generates a constant-current drive voltage using the provided power and the drive PWM signal. The output module generates a drive current that responds to the constant-current drive voltage. And the output module drives an external LED device using the drive current.
