Intelligent illumination device are disclosed that use components in an LED light to perform one or more of a wide variety of desirable lighting functions for very low cost. The LEDs that produce light can be periodically turned off momentarily, for example, for a duration that the human eye cannot perceive, in order for the light to receive commands optically. The optically transmitted commands can be sent to the light, for example, using a remove control device. The illumination device can use the LEDs that are currently off to receive the data and then configure the light accordingly, or to measure light. Such light can be ambient light for a photosensor function, or light from other LEDs in the illumination device to adjust the color mix.

The present invention provides a power adaptor for LED lamps, and an LED lamp system, each of which may achieve the function of light dimming in a current LED lamp without having to modify its original structure(s) wherein the current LED lamp originally could not have the function, or may achieve better dimming control of parallel-connected LED lamps. The power adaptor includes a power conversion circuit and a dimmer, in which the dimmer includes a dimming signal generating module and a signal combining processing module. The dimming signal generating module is configured to receive a dimming instruction and convert the dimming instruction into a dimming signal. The signal combining processing module is electrically connected to the dimming signal generating module and configured to modulate the power signal, according to the dimming signal, to produce an output signal for driving the LED lamp.
