Patent ID: 8901827

Claim:
A distributed garden light network, comprising a main unit, comprising at least one LED, a motion sensor and a radio frequency transmitter but no transceiver, wherein the main unit is configured to receive a signal from a motion sensor, determine the illumination state of the LED based on the signal from the motion sensor in combination of its initial illumination state, activate a wireless transmitter based on the signal from the motion sensor and send out a radio frequency signal wirelessly; and multiple secondary units, each comprising at least one LED having an initial illumination state, wherein each secondary unit is configured to receive the radio frequency signal from the transmitter of the main unit and determine the illumination state of the LED of the secondary unit based on the wireless input in combination with its initial illumination state, each main and secondary unit consisting essentially of four illumination states, an ACTIVATED state, having high brightness; an ALWAYS ON state, having a medium brightness; a STANDBY state, having low brightness and an OFF state, wherein the STANDBY state offers brightness between 2-10 lm with a lampshade, and the ACTIVATED state has a brightness five times or more than that of the STANDBY state, with a lampshade, wherein the ON and OFF state is exclusively controlled by a slide switch on the exterior of each unit; wherein the main unit and each of the secondary units is a wireless unit, self sustained and powered only by a replaceable rechargeable battery, said rechargeable battery being charged by an individual solar panel attached on the top or embedded on a top cover of the main and each of the secondary units, each solar panel having a geometry and dimension smaller than the size of the top cover of the main and secondary units, wherein the main unit comprises a controller, configured with a solar charging circuit, an over charging protection circuit, a rechargeable battery power supply circuit, an AUTO/OFF/ON switch control circuit, an illumination brightness and light-on period control circuit and a LED light element illumination circuit, wherein the illumination brightness and light-on period control circuit and the LED light element illumination circuit comprising a timing component and brightness component, wherein the controller can change the illumination state of LEDs from one illumination state to another illumination state according to a timing protocol corresponding to the signal received from either a motion sensor and a transmitter.
