Control instructions are transmitted to receivers by modulating light sources to generate light beams that are modulated with digital data streams for inducing control instructions in the light beams. Each light beam is applied to a pixel shaper element of a pixel shaper assembly to produce a light pixel, each light pixel carrying the control instructions of the light beam, each light pixel having a perimeter defined by the pixel shaper element. The pixel shaper assembly combines the light pixels into an image without significant overlap or voids between the light pixels. The light pixels are directed toward a projector lens for transmission toward the receivers. In a receiver, an optical receiver detects a light pixel. A controller decodes the control instructions received in the detected light pixel and uses the control instructions to control a function of the receiver.

Disclosed is a rectifierless light string that uses bidirectional LEDs. Each LED is illuminated on both the positive and the negative portion of an AC signal so that the AC signal does not have to be rectified. In addition, LEDs are mounted on LED holder plugs, which are designed to allow the LEDs and bypass resistors to be automatically inserted in the LED holder plug. The LED holder plugs are inserted into a light string socket that contains a shunt switch that provides a conduction path when the LED holder plug is not firmly inserted in the light string socket. In this manner, conduction can occur in the light string when the LED holder plug is dislodged.
