Abstract
A lamp dimmer suited for fluorescent and any other type of lights and/or lamps which controllably notches the alternative voltage cycle depending on the cycle programmed by the microcontroller. As the zero crossing point is sensed by solid state circuitry, one microcontroller senses the information and relays it to another microcontroller which has a progressive and non-interruptive control over the switching of the optocoupler. The notches are programmed with starting and ending points which can selectively notch the AC cycle in any position, giving the ultimate control over the amount of power delivered to the lamp. This type of control can be used to ultimately slice the timing of the North American 60Hz AC power cycle into steps within the millisecond region. A
infrared detector is used to sense the signals from any available infrared module which controls the timing delivered by the microcontroller. The sensor has a wide range of light spectrum giving access by any commercially available module control of this lamp dimmer. The sensor is separate from the control box, giving simple access to dimming functions by simple installation. Also, available is a stationary control for non-remote control.

Description
DESCRIPTION
BACKGROUND OF THE INVENTION
Field of the Invention This invention is directed towards light dimming systems and more particularly to a system suitable for dimming one or more fluorescent lamps, also capable of dimming all lamps in accordance with standard dimming lights.
In accordance with the present invention, the table lamp is usually strategically placed in a remote area of the room and therefore is subject to connections which are distributed within the home. Many inventions have a dimmer, which may or may not be controlled remotely, which is usually purchased for the purpose of installation within the wall electrical box. This makes control of multiple dimming functions a problem and therefore this invention addresses that problem. The present invention is a product which can be placed within the range of a light dimmer, and a wired infrared receiver can be glued and/or taped in any location for proper control of the dimming function. More specifically, the code which runs the dimming function, is simply an on-off signal from any infrared remote transmitter readily available in any household which is used to control the TV and/or the radio and/or the DVD and/or any other infrared remote product.
The following invention deploys two microcontrollers for microsecond switching and non-interruptible performance which is the preferred embodiment of the following invention.

It is to be noted, however, that the appended drawings illustrate only a preferred embodiment of the invention and are therefore not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments.
In The Drawings Fig 1.0 is a general block diagram of the preferred embodiment.
Fig. 1 A, 2A, 3A and 4A is a schematic diagram of a preferred embodiment of the present invention.
Description Of The Preferred Embodiment Now referring to the drawings, and first to Fig 1.0, a block diagram of a preferred embodiment of the invention is shown. The apparatus mainly the infrared receiver is independent of any enclosures and is particularly connected by a sizable length of wire which is placed and connected to the dimmer circuitry which is further explained by means of Fig lA through Fig 4A. The Infrared receives any code from any available remote control on the market and will control the dimming function of the circuit by counting pulses in the millisecond range. The invention has a manual control for ease in trouble-shooting the particular transmitter which is not included in this particular invention. The lamp in question will have a limit in the power consumption that will be constraint by the specifications and will have access to the AC standard in the particular country of use. The control box is further explained by means of Fig 1A
through 4A.
Fig 1A considers a down-conversion of the distributed line mainly by means of item 1, where the AC voltage is reduced in amplitude by the use of a transformer. The reduced voltage is further rectified by use of item 2 which is a solid state bridge rectifier to focus on delivering the correct DC bias to the entire dimmer circuit.
Further, the reduced AC voltage is tapped by the use of a resistor divider and channeled into item 3 which is a high performance voltage comparator to perfectly time the zero crossing of the AC voltage. This precise timing is fed to the second microcontroller for proper software analysis. Item 4, is there to deliver a plentiful positive 5.OVDC in order to power the entire circuit. Item 5, is preferably a positive to negative converter to power the negative rail of the comparator ( Item 3), this enables the correct bias for the solid state device and ensures precise timing coordinates. Item 6, is a means of proper regulation in removing unwanted spurious results.
Fig 2A considers the input coming from the infrared device, mainly by means of Item 7, given a local jack for proper mechanical input. Items 8 and 9, serve in amplifying the received signal and properly biased by Item 11, so that a clean signal-to-noise is preferred at this level. Item 10, serves mainly to compare the given received total input and is further discriminated by Item 12, where a needed threshold is properly determined.
This ensures that the "DETECT" signal is free from any noise levels coming from erroneous sources.
Fig 3A considers the effect of having two microcontrollers with software to precisely time the effects of cutting the power cycles and coming within microseconds of accuracy. Item 18, is mainly a mechanical switch which serves for manual interface. Item 17, is mainly an LED which serves to provide the user with visual aid to properly discern functionality. Items 13 and 14 are in effect the microcontrollers, which use an interrupt pin to properly detect signal change where the 1st microcontroller updates the 2d with the needed switching function, therefore providing the AC stability needed for precise power dimming of any given lamp. Items 15 and 16 are the heart of the microprocessors letting them be driven at speeds with a clock cycles of 20MegaHertz.
Fig 4A considers the effect that the control at a fairly low power is now needed to drive a high RMS Alternate Current. Item 19 is basically a device which gives in solid state form the necessary electrical isolation between low DC microcontroller signals and the high voltages needed to slice and switch at correct intervals. Item 20, is mainly the solid state switch which is known as a TRIAC, it is properly selected to provide the necessary amperage to the consumer lamp. Finally, Item 21 is the mechanical AC
plug which all standard lamps may be connected to.
