  • LED lamp head with variable brightness
    Patent number: 8552649
    Abstract: A lamp head is configured to be electrically coupled solely to a power-supply element and a return element. A power voltage carried by the power-supply element is regulated by a control element. The lamp includes at least one LED configured to emit light, and a first circuit coupled to the at least one LED and configured to adjust the brightness of the light emitted by the at least one LED solely in response to adjustments made to the power voltage by the control element.
