Anti-Flicker Apparatus for Motion Detector

摘要

An anti-flicker and anti-glow switchable load apparatus to be installed in the light socket of a commonly powered electronic switching device, such as a motion activated light switch. An energy efficient light bulb or lamp, such as a cathode fluorescent lamp or light emitting diode is then screwed into the apparatus. A first embodiment of the present invention includes a switchable light source, a switchable load, a controller, and a voltage sensor. When the present invention in the first embodiment detects a higher voltage, thus indicating the lamp has been switched from the “off” state to the on state, the switchable load is disconnected, and the current is re-routed to pass through the energy efficient lamp.

主权项

1. An apparatus for stabilizing an energy-efficient light connected to an electronic activated device, comprising:
a housing including a light socket for receiving an energy efficient light having a hot electrical lead and a ground electrical lead, and the housing including a threaded base for screwing into an electrical socket of an electronic activated device, wherein the hot electrical lead and the ground electrical lead are electrically connected to the threaded base; an electrical switch within the housing; an electrical load within the housing and electrically connected in series with the electrical switch between the hot electrical lead and the ground electrical lead, and the light socket and the electrical switch are electrically connected in series between the hot electrical lead and the ground electrical lead; a voltage sensor within the housing and electrically connected between the hot electrical lead and the ground electrical lead for detecting voltage level between the hot electrical lead and ground electrical lead, and the voltage sensor is connected in parallel with the electrical switch and the electrical load; a controller for monitoring status of the voltage sensor and controlling the electrical switch; wherein the controller sets the electrical switch to direct current through the electrical load when an electronic activated device to be connected to the threaded base is in a light-off state causing a lower voltage to be detected by the voltage sensor, thereby enabling a controlled current to pass between the hot electrical lead and the ground electrical lead via the threaded base and provide power to an electronic activated device to be connected to the threaded base, and the electrical switch is set to create an open circuit to the light socket of the housing so as to prevent any electrical current flowing to an energy efficient light to be located in the light socket of the housing; and wherein, when an electronic activated device to be connected to the threaded base is in a light-on state causing a higher voltage to be detected by the voltage sensor, the controller sets the electrical switch to direct current to flow through the light socket of the housing and activate an energy efficient light to be contained therein, and the electrical switch is set to create an open circuit to the electrical load so as to prevent any electrical current flowing to the electrical load and wasting energy thereto.
