Abstract

A programmable touchscreen light source dimmer is provided. The present invention comprises a dimmer circuitry housing that fits within a conventional light switch box, a removable faceplate, and optionally a cover that may be affixed over the faceplate. The present invention uses a microcontroller that is able to alter the output signal that is used to control the luminosity of the connected light sources between PWM and reverse phase control so that the type of dimming is ideally suited for the type of light source. The faceplate has a dynamic touchscreen through which users can easily alter the luminosity of connected light sources, program that device to follow preset schedules or respond to external stimuli, or activate various secondary functions.

Claims

1. A programmable touchscreen dimmer, comprising:

a control housing;

a faceplate having a touchscreen, said faceplate removably affixed to said control housing;

a control interface disposed on said control housing;

said control interface connecting said control housing and said touchscreen such that said control housing and said faceplate are able to interact and share data and inputs between each other;

a dimmer subsystem alternately utilizing pulse-width modulation and reverse phase control to regulate an amount of power received by a light fixture connected to said programmable touchscreen dimmer;

said touchscreen displaying a user interface;

said user interface adapted to receive inputs from a user and thereby modulate said dimmer subsystem;

wherein said control housing is connected to a light fixture and said dimmer subsystem is adapted to control the luminosity of said light fixture.

2. The programmable touchscreen dimmer of claim 1, wherein said control housing is shaped to fit within a conventional electrical outlet box.

3. The programmable touchscreen dimmer of claim 1, further comprising:

a wireless connectivity subsystem capable of receiving wireless inputs from a user via an electronic device;

wherein said wireless connectivity subsystem relays said wireless inputs to said dimmer subsystem.

4. The programmable touchscreen dimmer of claim 1, wherein said touchscreen is adapted to display an image after a preset period of time without user input.

5. The programmable touchscreen dimmer of claim 1, wherein said dimmer subsystem can be programmed to follow a schedule set by a user.

6. The programmable touchscreen dimmer of claim 1, further comprising a motion sensor.

7. The programmable touchscreen dimmer of claim 6, wherein said touchscreen is adapted to display an image after a preset period of time without detecting movement via said motion sensor.

8. The programmable touchscreen dimmer of claim 1, wherein said user interface comprises a luminosity bar capable of receiving actuation from a user and said dimmer subsystem to alter said amount of power received by said light fixture.

9. The programmable touchscreen dimmer of claim 1, wherein said user interface further includes at least one additional means for user input.

10. The programmable touchscreen dimmer of claim 1, wherein said dimmer subsystem automatically selects between pulse-width modulation and reverse phase control to regulate an amount of power received by a light fixture connected to said programmable touchscreen dimmer.

11. The programmable touchscreen dimmer of claim 1, wherein a user is capable of selecting between pulse width modulation and reverse phase control for said dimmer subsystem utilizing said user interface.

12. The programmable touchscreen dimmer of claim 1, further comprising a memory unit for storing user uploaded images.
