ABSTRACT:
A cordless lighting system for a Christmas tree comprising a control transmitter for generating light signals of first and second frequencies, and a plurality of light elements adapted to be supported on the Christmas tree. Each of the light elements comprises a light source for generating visible light, a battery for supplying power to activate the light source, a bistable switch having an input, and an output connected to the light source, and first and second photocells responsive to light signals of the first and second frequencies, respectively, for generating first and second control signals to the input of the bistable switch. The first control signal controls the bistable switch to activate the light element and the second control signal controls the bistable switch to deactivate the light element. Preferably, the light elements activate each other in a cascade fashion.
