Abstract

The invention is an induction-based lighting system designed to provide power to model displays and other similar applications. The first part of the system is the wireless Power Mat that is placed under the model houses and used as the base for the village, and contains a primary winding that interacts with secondary windings placed inside display components to provide lighting effects, such as one finds in model Christmas villages. The electrical characteristics of the primary winding can be controlled by a microcontroller to make lights in the models blink or change as a user desires.

Claims

1. A Lighting System, comprising:

a. a Power Mat that creates a time-varying electromagnetic field in the vicinity of the Mat using a direct current voltage source, oscillator, driver, capacitor and electrical coil; and

,

b. embeddable wireless illumination Tags constructed with a parallel-turned LC-resonant circuit and light-emitting diode (“

LED”

), tuned to frequencies compatible with the Power Mat, so that when the Power Mat is energized and creating the electromagnetic field, the LED on the Tags emit light when the Tags are placed on the Power Mat.

2. A Lighting System of claim 1 with an additional Auxiliary Mat, comprising:

a. A mat,

b. An Auxiliary Winding, an electrical winding constructed such that the windings are embedded in the mat and encircle the mat area;

c. A Capacitor set in series with the Auxiliary Winding,

d. A relationship between the Auxiliary Winding'"'"'s inductance and the Capacitor'"'"'s capacitance so that the two components form a tuned circuit that will respond to an electro-magnetic field generated by the Power Mat'"'"'s Primary Winding, transferring power form the Power Mat to Tags placed on the Auxiliary Mat, when the Auxiliary Mat is positioned near to, or on, the Primary Winding of the Power Mat.

3. The Lighting System of claim 1, with Tags integrated into objects such as toys, displays, models, glasses, and shoes.

4. The Lighting System of claim 1, with Tags that include additional electronic components to support blinking and flickering of the Tag'"'"'s LED.

5. The Lighting System of claim 1, with Tags that include additional electronic components to allow a Tag to continue emitting light after being removed from the Mat'"'"'s electro-magnetic field.

6. The Lighting System of claim 1, with a Mat and Tags that include additional electronic components to allow a Timer and Button to allow the user to activate a specific Tag for a fixed or variable length of time or at a certain time of day based on the Mat'"'"'s operation at specific frequency.

7. The Lighting System of claim 1, with a Mat and Tags that includes switches, environmental sensors, and additional electronic components to allow the System to respond to changes of state of the switches to create programmed responses in Tag lighting effects.

8. The Lighting System of claim 1, with a Mat and Tags that includes a light sensor and additional electronic components to allow the System to respond to changes in ambient lighting with programmed responses in Tag lighting effects.

9. The Lighting System of claim 1, with a Mat and Tags, in which the Mat employs multiple frequencies to energize Tags tuned for those frequencies.

10. The Lighting System of claim 1, with a Mat that can operate at multiple frequencies using time slicing and/or superposition of drive control signals to power Tags tuned to different frequencies, e.g., 125 kHz, 120 kHz, 115 kHz to create lighting effects such as steady on, blinking, dimming, or flickering.

11. The Lighting System of claim 1, with a Mat that can operate at multiple frequencies, e.g., 125 kHz, 120 kHz, 115 kHz using time slicing and/or superposition of drive control signals to power Tags with multiple independent LEDs of different colors (e.g., red, green, blue) and coils tuned to different frequencies, to create lighting effects and color changes.

12. The Lighting System of claim 2, with the additional element of physical connectors on the edges of the Power Mat and Auxiliary Mat so they can connect to each other for proper positioning to maximize power transfer between the mats.

13. A method of announcing drink specials and making important announcements, comprising:

a. Installing an LED Tag into the bottom of a drinking mug, glass, plate, check holder, menu or other object;

b. Installing an Advanced Power Mat into all the bar table top;

c. Installing a user interface for the Power Mats, so a user can energize all the tables with a particular frequency, and all the glasses being used will be illuminated or flash, or change colors as directed by the User.
