## Background
CROSS REFERENCE TO RELATED APPLICATION
This application is an international application which is based on and claims priority under PCT Rule 4.10(a) from provisional Application Ser. No. 60/983,379, filed on Oct. 29, 2007 in the United States of America.


FIELD OF THE DISCLOSURE
The present disclosure relates to a circuit for lighting devices and, more particularly to a modular circuit for color changing LED devices with volatile active emissions and hidden input jacks.
BACKGROUND OF THE DISCLOSURE
Creating a pleasant ambiance is a popular aspect of home decor. This is often achieved through various combinations of pleasant fragrances with mood lighting. Lighting can also be combined with other functions such as air sanitization, air deodorization, and the controlled release of insect repellent, insect attractant and insecticide. Conventional products such as scented candles, mood lighting devices, fragrance dispensers, and the like, are commonly used to create a pleasant environment in the home. While those conventional products help to create a pleasant living environment and ambiance, they have their drawbacks.
For example, while scented candles create soft light and fragrance, which creates a pleasant mood, candles are a potential fire hazard and often produce unwanted smoke and wax drippings. Traditional light fixtures and lamps do not provide the color effects, fragrance emission or other volatile active emissions that users often desire. While stand-alone aesthetic devices are available for providing lighting effects (such as color changing and the like), these stand-alone devices do not provide volatile active emissions and take up additional space around the home, adding to the clutter that many consumers are trying to avoid. Additionally, light fixtures and stand-alone devices have external switches, power cords, and the like, which make the devices themselves unattractive.
Furthermore, traditional light fixtures, lamps and stand-alone devices require a DC power supply, an AC power supply, or a combination of both. More specifically, a device requiring a DC power supply uses batteries and a device requiring an AC power supply uses a power cord. A device that uses batteries eliminates the need for unsightly power cords and does not take up additional outlets. However, batteries provide limited power and need to be replaced periodically, resulting in additional costs to the consumer. Alternatively, a device that uses a power cord minimizes additional expenses to the consumer. However, the power cord adds clutter to the home and takes up additional outlets.
A device that provides a combination of both DC and AC power supplies, or a dual power supply, gives the consumer the option of selecting between the two sources. In general, such devices include a compartment for batteries and an input jack for an adapter plug. When using the DC power supply, batteries are supplied to the device and the input jack is left unplugged. When using the AC power supply, the batteries are removed and an adapter is connected between the input jack and a wall outlet. While dual power supplies offer the benefits of both power options to the consumer, such devices are generally sold without the adapter. In order to take full advantage of the dual power supply without the added costs, the consumer is forced to locate an unused adapter around the house. However, it is usually more difficult to find an adapter matching the exact size and voltage rating as required by the input jack.
Conventional fragrance dispensers, such as plug-in diffusers, can provide pleasing aromas in a relatively inexpensive, compact package. However, such conventional fragrance dispensers generally take up outlets and are often located out of sight, causing a user to forget to adjust or refill the device. While these fragrance dispensers may also provide light, because the devices are used in existing electrical outlets, they are generally positioned too low to provide effective lighting features, other than to operate as a nightlight.
Conventional nightlights include only white light emission in combination with fragrance emission. While a single scent may be provided in the form of a decorative diffuser, colored nightlights are not generally available and there is no coordination between the light color emitted and the particular fragrance emitted. Moreover, sophisticated multi-colored lights that change color and that are aesthetically pleasing in combination with fragrance emission are not currently available.
Further, numerous needs exist for devices providing the combination of white light and/or colored light with volatile active emissions other than fragrances, such as air sanitization, air deodorization, the controlled release of insect repellent, insect attractant, insecticide, aromatherapy volatiles or other non-fragrant materials (any of which may be combined with fragrant materials if necessary to make the ambient environment more tolerable). More importantly, numerous needs exist for compact modular circuits enabling the combinations of colored light and volatile active emissions. Modular circuits allow for the interchangeability of parts and features while also promoting expandability.
Recent developments in lighting have led to advancement in light emitting diodes (LEDs) and supporting drive circuits. An LED is a semiconductor device that emits visible light when an electrical current passes through it. The light from an LED is basically monochromatic and the color of the light is determined by the particular material used in the semiconductor (although current applied to the LED can be used to vary the perceived color). LEDs have the advantage of low power requirements, high efficiency and long life. The outputs of several different colored LEDs can be mixed so as to produce additional colors, including white light, and different intensities. LEDs can also be used to provide background lighting to achieve desired ambient effects. Until now, LEDs and supporting circuitry have been generally used for such applications as indicator lights, panel backlighting and fiber optic data transmission.
LED lamps having multicolor adjustors with supporting circuitry or the like exist. These devices typically comprise a base in which several LEDs capable of producing different colored light are mounted upon a circuit board. The circuit provides adjustable and external switches for the different color LEDs so that the colors can be mixed in any desired ratio to produce desired lighting effects such as varying colors and intensity.
Devices also exist having circuits for providing ambient light from a free-standing lamp using LEDs. In one such device, ambient light in the form of a simulated candle is provided by a microprocessor and supporting circuitry emitting both color combinations and flicker effects. These devices are directed toward lamps with external switches for achieving soothing ambient effects. There are also other devices with circuits for controlling the light output of several LEDs according to user input and the predetermined program installed. The user input is provided by external switches disposed on a housing. However, there is no device or circuit having aesthetically pleasing and discrete switches that allow user control of volatile active emissions and ambient light with multiple colored LEDs within a single fixture.
Therefore, multiple needs exist for controllers and related circuitry that provide for discrete switches and the combination of one or more of the following functions: white light emission; colored light emission; colored light shows; fragrance emission; air sanitization; air deodorization; insecticide emission; insect repellent emission; aromatherapy material emission; light emission that repels insects; light emission that attracts insects; and any combinations thereof. Furthermore, needs exist for the modular design of the circuitry. Additional needs exist for controllers and related circuitry that provide dual power supplies having an input jack capable of receiving a wide range of adapters, in terms of both plug sizes and voltage ratings.

It should be understood, however, that there is no intention to limit the present invention to the specific forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions, and equivalents falling with the spirit and scope of the present invention.
DETAILED DESCRIPTION OF THE DISCLOSURE
Referring now to the drawings and with particular reference to FIGS. 1-3, exemplary color changing LED devices having volatile active emissions are generally referred to as reference numeral 10. With further reference to FIGS. 4 and 5, exemplary control units for emitting light and volatile actives are generally referred to as reference numeral 20. It is understood that the teachings of the disclosure can be used to construct control units and related circuitry above and beyond that specifically disclosed below. One of ordinary skill in the art will readily understand that the following are exemplary embodiments.
One example of a device that may use the circuitry and electronics described herein is shown in FIGS. 1A and 1B. The color changing light source and volatile active dispenser or device 10 may provide a translucent globe 12 coupled to a base 14. The translucent globe 12 may serve to at least partially diffuse, transmit and/or reflect light, while the base 14 may provide circuitry and electronics for driving the device 10 in response to user input. A volatile active cartridge 16 may be partially disposed within the translucent globe 12 for emitting a volatile active. The device 10 may provide a more aesthetically pleasing design by eliminating external switches and by using the active cartridge 16 as the user interface, as discussed more specifically below.
As shown in more detail in FIG. 1B, the volatile active cartridge 16 may be removably coupled to the base 14 via a key 18 and a corresponding switch 19. More specifically, the key 18 may be any shape or form disposed on the cartridge 16 and mateably received by the switch 19, such that rotating the cartridge 16 also rotates the key 18 and the associated switch 19. Rotating and/or changing the relative position of the switch 19 with respect to the base 14 may cause the device 10 to perform different tasks. Alternatively, pushing the cartridge 16 toward the base 14, and thus pressing the switch 19, may also initiate a task. The device 10 may also include more than one type of switch 19 such that the device 10 responds to a cartridge 16 and key 18 that may be turned, rotated, pressed, pulled, tilted, touched, or any combinations thereof.
A second example of a device that may also use the circuitry and electronics, as described herein, is shown in FIGS. 2A and 2B. The color changing light source and volatile active dispenser or device 10a may provide a translucent globe 12a coupled to a base 14a. As with the device 10 of FIGS. 1A and 1B, the translucent globe 12a may serve to partially diffuse light, while the base 14a provides various circuitry and electronics for driving the device 10a in response to user input. Furthermore, a replaceable cartridge 16a is partially disposed within the translucent globe 12a for emitting a volatile active and for providing an aesthetically pleasing user interface.
In the more detailed drawing of FIG. 2B, the volatile active cartridge 16a is removably coupled to the base 14a via a key 18a and a corresponding switch 19a. More specifically, the key 18a may be any shape or form that is disposed on the cartridge 16a and mateably received by the switch 19a, such that rotating the cartridge 16a also rotates the switch 19a. In a similar manner to the device 10 of FIG. 1B, rotating and/or changing the relative position of the switch 19a with respect to the base 14a may cause the device 10a to perform different tasks. Alternatively, pushing the cartridge 16a toward the base 14a, and thus pressing the switch 19a, may also initiate a task. The device 10a may also include more than one type of switch 19a such that the device 10a responds to a cartridge 16a and key 18a that may be turned, rotated, pressed, pulled, tilted, touched, or any combination thereof.
Yet another device that may use the circuitry and electronics, as described herein, is shown in FIGS. 3A and 3B. The color changing light source and volatile active dispenser or device 10b may provide a translucent globe 12b coupled to a base 14b. As with the embodiments of FIGS. 1-2, the translucent globe 12b may serve to partially diffuse light, while the base 14b provides various circuitry and electronics for driving the device 10b in response to user input. A replaceable cartridge 16b is partially disposed within the translucent globe 12b for emitting a volatile active and for providing an aesthetically pleasing user interface.
As in the previous embodiments, the volatile active cartridge 16b may be removably coupled to the base 14b via a key 18b and a corresponding switch 19b. More specifically, the key 18b may be any shape or form that is disposed on the cartridge 16b and mateably received by the switch 19b, such that rotating the cartridge 16b also rotates the switch 19b. In a similar manner to the embodiments of FIGS. 1-2, rotating and/or changing the relative position of the switch 19b with respect to the base 14b may cause the device 10b to perform different tasks. Alternatively, pushing the cartridge 16b toward the base 14b, and thus pressing the switch 19b, may also initiate a task. The device 10b may also include more than one type of switch 19b such that the device 10b responds to a cartridge 16b and key 18b that may be turned, rotated, pressed, pulled, tilted, touched, or any combination thereof.
Referring now to the schematic of FIG. 4, an exemplary control unit 20 is provided having various subcomponents or modules. The modularity of the control unit 20 provides a flexible design that may be expandable or adaptable to a number of product configurations. More specifically, the individual modules representing different features may be interchanged or taken away from the control unit 20 depending on the desired application or product. The control unit 20 may also be configured to accept auxiliary modules, which while attached may override any redundant components within the control unit 20. In particular, the control unit 20 may include modules for a user interface 22, a driver circuit 24, a microprocessor 26, a light emitting diode (LED) array 28, volatile active dispensers 30, 31, 32, auxiliary connections 33 and a power jack 34. Alternatively, smaller but upgradable controllers may be constructed for more simple applications. For example, the control unit 20a of FIG. 5 provides a user interface 22a, driver circuit 24a, an LED array 28a and a power jack 34a similar to those of FIG. 4, but offers a smaller microprocessor 26a and a fewer number of features. More specifically, the control unit 20a of FIG. 5 may provide only one volatile active dispenser for dispensing volatile actives, such as a low output fan 30a, while the control unit 20 of FIG. 4 provides a low output fan 30, a high output fan 31 and a heater 32. Furthermore, the control unit 20a of FIG. 5 may omit the auxiliary connections 33 found in the control unit 20 of FIG. 4. The plurality of LEDs on the LED array 28 and 28a of FIGS. 4 and 5, respectively, may each be disposed on a satellite LED board 35.
The schematic of FIG. 6 illustrates another exemplary user interface module 22b that may be used with a color changing LED device having volatile active emissions, such as the device 10 of FIG. 1. Unlike the user interface modules 22, 22a of control units 20, 20a, the user interface 22b of FIG. 6 provides two tact switches 22b1, 22b2 wherein each switch 22b1, 22b2 may be electrically closed or opened based on the position of a key 18. The user interface module 22b may alternatively comprise slide switches, toggle switches, push buttons, or combinations thereof. The user interface module 22b may also provide fewer or more switches depending on the key 18 type. In the present embodiment, engaging the key 18, for example by pressing or rotating the key 18, may electrically open one or more of the switches 22b1, 22b2, transmitting a 5 VDC, or a logical high signal, to an input of a connected microprocessor 26. Accordingly, when the key 18 is not engaged by a user, switches 22b1, 22b2 may be electrically closed to transmit a 0 VDC, or a logical low signal, to an input of a connected microprocessor 26. The resulting action corresponding to the different combinations of input from the tact switches 22b1, 22b2 may be dependent on a predetermined sequence of operations stored within the microprocessor 26.
Turning to FIG. 7, a more detailed view of a driver circuit 24b similar to the driver circuit 24 of FIG. 4 is provided. While many other configurations are possible, the driver circuit 24b of FIG. 7 serves as a buck-boost converter having an input 24b1 and an output 24b2. The driver circuit 24b may be configured to accept a wide range of DC input voltages, for example between 2 to 10 VDC, at the input 24b1 from a power source, for example, one or more batteries, or the like. The buck-boost converter serves to buck or boost the received input voltage to a predetermined DC output voltage, for example 5 VDC, at the output 24b2. The output 24b2 may provide the DC voltage required to power the rest of the control unit 20, for example the microprocessor 26, the LED array 28, and the volatile active dispensers 30, 31, 32. If needed, the driver circuit 24b may also provide additional current for any connected auxiliary modules 33. Based on the application, the driver circuit 24b may alternatively take the form of a buck converter, a boost converter, or any other voltage converter.
Referring back to FIG. 4, the driver circuit 24 may provide power to the reference terminals of the microprocessor 26, for example, 5 VDC across pins 1 and 14. One or more tact switches may be coupled to the inputs of the microprocessor 26, for example via pins 2 and 10, to selectively enable the LED array 28 and/or the volatile active dispensers 30, 31, 32 according to user input. Depending on the selected mode of operation, the microprocessor 26 may generate signals at output pins, for example pins 6-8 and 11-13, corresponding to the volatile active dispensers 30, 31, 32 and the LED array 28, respectively. Particularly, pulse width modulated (PWM) signals may be generated at the output pins according to a predetermined sequence of operations stored within the microprocessor 26.
As shown in FIG. 8, another exemplary LED array 28b may include a plurality of colored LEDs arranged in clusters of red, green and blue (RGB) LEDs 28b1-3. Power to the LED array 28b may be provided by a driver circuit 24, which is coupled in parallel to the LED array 28b. The microprocessor 26 may control one or more colors of the LED array 28b by selectively enabling a plurality of transistors 28b4-6. More specifically, the transistors 28b4-6 may turn on the LEDs 28b1-3 by enabling current to pass through the respective LEDs 28b1-3. For example, the first transistor 28b4 enables current to the red LEDs 28b1, the second transistor 28b5 enables current to the green LEDs 28b2, and the third transistor 28b6 enables current to the blue LEDs 28b3. Alternatively, the LED array 28b may comprise fewer or additional LEDs, and may also comprise LEDs of colors other than red, green or blue. The LED array 28b may also be extended to include a white LED and a corresponding transistor for providing illumination light. Furthermore, to evenly distribute and to optimize lighting effects, the LEDs 28b1-3 of the LED array 28b may be distributed radially on a satellite LED board, or the like.
As described above, a predetermined sequence of multicolor light shows may be preprogrammed onto the microprocessor 26. In an exemplary sequence, light shows from the LED array 28 may be enabled first by rotating the key 18 to an on position. Subsequently, the microprocessor 26 may begin a first of a plurality of light shows and begin cycling through the different colors. Once the switch 19 associated with the key 18 has been pressed, the microprocessor may toggle to a subsequent light show. Similarly, consecutive presses of the switch 19 may toggle the microprocessor 26 through any remaining light shows. During any point in the sequence, pressing and holding the switch 19 may instruct the microprocessor 26 to pause and hold one color instead of cycling through light patterns. The microprocessor 26 may be programmed to hold a color until the switch 19 is pressed a second time. Rotating the key 18 into an off position may remove all power from the control unit 20. Alternatively, the sequence may further include selective control of a volatile active dispenser 30, 31, 32 to alter volatile active emission rates, control of an optional white LED, or the like.
Turning to FIG. 9, an exemplary volatile active dispenser module 30b for a low output fan 30b1 to facilitate volatile active emissions from a passive delivery element is provided. More specifically, a connected microprocessor or microcontroller 26b may increase or decrease volatile active emission rates in response to user input. The volatile active dispenser 30b may be powered by the driver circuit 24 of FIG. 4 and controlled by an output of the microcontroller 26b, for example, pin 10. The microcontroller 26b may selectively enable the volatile active dispenser 30b by controlling current to the transistor 30b2. More specifically, an enabling signal from pin 10 of the microcontroller 26b may cause the transistor 30b2 to switch on, allow current to flow through the low output fan 30b1, and thus, increase the volatile active emission rate. Accordingly, a disabling signal from pin 10 of the microcontroller 26b may cause the transistor 30b2 to switch off, prevent current flow through the low output fan 30b1, and decrease the volatile active emission rate. Similarly, the volatile active dispenser 30b may be adapted to incorporate a high output fan, a heater element, a piezo electric atomizer, or combinations thereof. A high output fan may require additional power supplied by an auxiliary power source or an adapter. A heater element may comprise a ceramic encased metal oxide heater powered by the driver circuit 24 or an additional power source. A piezo electric atomizer may comprise a control system which may also be powered by the driver circuit 24.
Referring now to FIG. 10, an exemplary battery compartment 36 for housing a DC power source is shown with batteries 38 and a compartment lid 40. The size and number of batteries 38 required may vary depending on the type of the driver circuit 24 employed and the amount of load connected to the driver circuit 24. As in the exemplary embodiment of FIG. 4, the driver circuit 24 may be configured as a buck-boost converter which converts any input voltage between 2 and 10 VDC to a 5 VDC output. Specifically, the compartment 36 may house, for example two to four AA alkaline batteries in series for providing 3 to 6 VDC, respectively. The battery compartment 36 may also include a hidden input jack 42 for receiving an adapter plug 44, which may be associated with, for example the power jack module 34b of FIG. 11. The power jack module 34b may be used to supply additional power to components that consume more power than the driver circuit 24 is capable of producing. In the exemplary schematic of FIG. 11, the power jack module 34b is configured to accept regulated 5 VDC, for example, from a plug-in class 2 power supply. Alternatively, the input jack 42 may be configured to receive more than just one type of plug 44, such that a wider range of adapters, in terms of physical size and voltage ratings, may be used. Aside from convenience, this also enables the device to be sold, and consumers to purchase the device, without the expense of a specially designed power adapter of its own. Moreover, the hidden input jack 42 may be disposed inside the battery compartment 36 to provide a more compact, clean and aesthetically pleasing design.
Based on the foregoing, it can be seen that the present disclosure provides control of color changing LED devices with no external switches, volatile active emissions and a hidden input jack. The modular design of the disclosure enables its application to a wide range of devices with similar features. The disclosed modules further promote the interchangeability and the expandability of modules and features associated with the disclosure.
While only certain embodiments have been set forth, alternatives and modifications will be apparent from the above description to those skilled in the art. These and other alternatives are considered equivalents and within the spirit and scope of this disclosure.
