## Title
Ion generating light assembly

## Abstract

A light to plug into a wall socket having a negative ion generator in the form of a pin. The pin design can be easily cleaned with a swab and cleaning solution such as rubbing alcohol, eliminating the need to trim or clean a brush electrode when corrosion or deposits form. The negative ion generator is always on and produces the negative ions to purify the air. The device can have a light sensor to activate the light when light is low. The device can also come with light emitting diodes which can be set to indicate the status of the various systems of the device. The device can come equipped with an air freshener that disperses vaporized perfume into the air.

## Background

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
This invention was not made using federally sponsored research and development. The inventor retains all rights.
BACKGROUND OF THE INVENTION
There are numerous inventions generating negative ions for one purpose or another, many of which claim both a positive and a negative pole or have a brush shaped ion generator. Excessively complex generators can greatly reduce life span of the device because, frankly, difficulties in cleaning generally result in no cleaning. Cleaning techniques involving the trimming of brush filaments will obviously result in reduction of the brush filament surface area available. Eventually the ion generating surface is either so oxidized or corroded that the number of ions emitted is substantially reduced or else the ion generating surface is reduced to nothing by the act of trimming. Either way a new device becomes necessary. Frequently generating negative ions is for the purpose of cleaning the air. Other devices exist which provide fragrances for the air, thus masking disagreeable odors. Sometimes these fragrance distributors are combined with a plug in night light. These devices do not actually clean the air of underlying odor causing agents. They simply add other chemicals into the air. Other devices exist which feature a night light that can be automatically activated in the event there is no illumination. The light is switched on automatically at night.
BRIEF SUMMARY OF THE INVENTION
A light to plug into a wall socket having a negative ion generator in the form of a pin. The pin design can be easily cleaned with a swab and cleaning solution such as rubbing alcohol, eliminating the need to trim or clean a brush electrode when corrosion or deposits form. The pin does not become oxidized as fast as the typical brush style electrode. This represents an improvement over prior art devices which present cleaning difficulties that result in limited useful life span of the device. The negative ion generator is always on while the device is plugged into a wall socket and produces the negative ions to purify the air. The device has a light and can have a light sensor to activate the light when light is low. The device can also come with light emitting diodes which can be set to indicate the status of the various systems of the device. The device can come equipped with an air freshener that disperses vaporized perfume into the air.

DETAILED DESCRIPTION OF THE INVENTION
A light to plug into a wall socket having a negative ion generator in the form of a pin. The pin design can be easily cleaned with a swab and cleaning solution such as rubbing alcohol, eliminating the need to trim or clean a brush electrode when corrosion or deposits form. This represents an improvement over prior art devices which present cleaning difficulties that result in limited useful life span of the device. The negative ion generator is always on when the device is plugged into a wall socket and produces the negative ions to purify the air. The device can also come with light emitting diodes which can be set to indicate the status of the various systems of the device. The device can come equipped with an air freshener that disperses vaporized perfume into the air. It has an energy saving light mounted in a socket, a control circuit connected to the socket, a means to activate or deactivate the light, a negative ion generator in the form of an easily cleanable pin, and a voltage amplification circuit that outputs to the negative ion generating pin. The ions that are generated are negative. They result in a breaking down of the ions in the air either to positive or negative. The negative ions that are generated by the device are convected and cause a binding of the heavier positive ions (which are undesirable) so that they fall to the floor or are deposited on the pin. These positive ions are undesirable because they are unhealthful and/or cause odor. A housing means contains the invention, which in the preferred embodiment is a plastic case shaped in an esthetically pleasing form from which the plug members extend that can be inserted into a standard wall socket. The light also extends outside the housing so it can illuminate the room on demand. If there are LEDs they extend from the surface of the housing, as does the light sensor. There is an aperture from which the negative ions issue forth. The pin is disposed inside the housing and either the housing can be opened or, in the preferred embodiment, the aperture is large enough to admit a swab so the pin can be easily cleaned with a swab using a solution perhaps containing alcohol.
