High efficiency light compatibility device

Abstract

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.

AI Technical Summary

Benefits of technology

The present invention is an inexpensive and energy-efficient device that can be easily installed by consumers to prevent flickering and glowing of energy-efficient lighting elements when connected to commonly powered electronic switching devices. The device includes a switchable light source, a switchable load, a controller, and a voltage sensor. It is designed to minimize the load on the amperage passing through it when the light is turned off. When the light is turned on, the device detects higher voltage and disconnects the load to direct power to the energy-efficient lamp, saving power and preventing the lamp from being fired. The second embodiment also includes a load resistor to keep the voltage low across the hot and neutral line.

Problems solved by technology

Within the next few years incandescent light bulbs are not expected to be available in the marketplace of the United States.

For instance, it has been discovered that fluorescent light bulbs do not function properly when connected to commonly powered electronic switching devices such as motion detectors, electronic timers, and other devices requiring a low current to pass through the lighting element to provide power to the electronic switching device while the lighting element is in the “off” state.

This is typically required due to the wiring limitations of residential homes and other building structures, wherein a small current is required to pass through the lighting element in order to provide current to the electronic switching device.

The filament used in incandescent light bulbs allows small currents to pass through the incandescent light bulbs without lighting the bulb because the small current does not experience enough resistance to cause the filament to heat up and glow or light.

The reason for this condition with the various bulbs is due to the parasitic load control device when in an “off” state has some minimal level of leakage current which it adversely effects the high efficiency bulbs and the bulbs attempt to turn on.
