  • Patent number: 9544969
    Abstract: Electronic circuitry for color-mixing in an LED light fixture during AC power dimming is disclosed to achieve adjustable color temperature. According to one embodiment, a dimmable LED light fixture has first, second, and third LED light sources, the first and second LED light sources producing white light, the third LED light source producing colored light, the LED driver configured to power the LED light sources by providing a single-channel variable-DC current source having two output terminals, and a current regulator for maintaining the current in the third LED light source path substantially constant as the LED driver output current is decreased when the AC power is reduced by the dimmer module, thereby altering the color of the light produced by the combination of the LED light sources.

  • Publication number: 20070056447
    Abstract: A mug body has an open top. A lid is fitted to the open top. The lid has first and second top to bottom holes formed therein. An arm extends down from the bottom of the lid into the mug body. An actuator handle extends out from the top of the lid, through the second hole. The actuator handle is coupled to the arm to move the arm relative to the mug body. Other embodiments are also described and claimed.
