An LED lightbulb is disclosed. The LED lightbulb includes at least two sets of LEDs that emit two different color temperature light and that are located on a metal core printed circuit board. The combine intensity outputs of the at least sets of LEDs generate a selected corrected color temperature output. The corrected color temperature output is changed by rotating a diffusing unit with a conductive contact pad that engages contact tracks on color corrected temperature (CCT) buttons and thereby closing a circuit corresponding to a selected corrected color temperature output.

LED lightbulb with adjustable color temperature

An LED plug-in lamp is disclosed that has a plug head which converts between a G24Q 4-pin plug head and a G24D type 2-pin plug head. The A LED plug-in lamp includes a detachable plug head cap or pin cover that detachably couples to the plug head to thereby form a G24Q 4-pin plug head or is removed from the plug head to thereby from a G24D type 2-pin plug head.

LED lamp with adaptable plug-in pin configuration

A LED track-light fixture is disclosed. The LED track-light fixture includes a canister assembly and a LED light module. The LED light module includes a LED light engine surrounded by a heat sink with vertical cooling fins fit into the canister assembly. The LED light module electrically couples to a driver assembly therein through matched sets of contact connectors. The canister assembly and a LED light module have matched guide features to ensure that the LED light module is installed in the proper rational orientation and the LED light module is preferably secured within the canister assembly through a fixing ring structure.

Track-light fixture

An LED plug-in lamp is disclosed that has a plug head which converts from a G24Q 4-pin plug head to a G24D type 2-pin plug head when a collar structure on the plug head is rotated relative to a fixed stage structure. The collar structure has two pin-stop features and two pin hole cover features. Rotating the collar structure relative to the fixed stage structure moves the two pin-stop features and allows the two reachable contact pins can be retracted through corresponding pin holes on the fixed stage structure and places ends of the pin hole cover structures over corresponding pin holes.

An illumination device including an LED mounting platform () having a peripheral region () and a relatively inner region (b); at least one warm white LED () and at least one cool white LED () mounted adjacent the peripheral region () of the LED mounting platform (), and, at least one RGB LED () mounted adjacent the relatively inner region () of the LED mounting platform (); a diffusion cover () configured to allow light emitted from the at least one warm white LED (), the at least one cool white LED (), and the at least one RGB LED () to pass therethrough; and wherein at least one light emission characteristic of light emitted from the at least one warm white LED (), the at least one cool white LED (), and/or the at least one RGB LED () is configured to be selectably varied in response to an input control signal so as to produce a plurality of lighting modes.

LED illumination device and method

A dimmable LED module configured for electrical connection with an AC mains power supply via a switch (), the dimmable lighting module including a plurality of activatable LED light sources configured for emitting a corresponding lighting characteristic when activated, and, a control unit () configured for selectably activating at least one of the plurality of LED light sources in response to a control signal generated by a predetermined switching operation of the switch () that is received by the control unit () such that a plurality of lighting modes are able to be selectably output from the dimmable LED module corresponding to the at least one of the plurality of LED light sources that are selectably activated by the control unit (), the plurality of lighting modes being indicative of a resulting lighting characteristic emitted by the at least one of the plurality of selectably activated LED light sources corresponding to the lighting modes, wherein the plurality of lighting modes include at least a first lighting mode and a second lighting mode whereby the second lighting mode is indicative of a resulting lighting characteristic that is relatively dimmed compared to that of the first lighting mode.
