     BACKGROUND 
     Field of the Invention 
     The invention is in the field of lighting and more specifically in the fields of colored lighting and variable intensity lighting. 
     Related Art 
     The art includes three-way bulbs configured to operate in lighting fixtures configured to power these three-way bulbs. See for example, U.S. Pat. No. 486,334 to Hall et al. These legacy lighting fixtures include a 3-way receptacle configured to receive a base of the three-way bulb. The receptacle typically includes two hot contacts and a neutral contact configured to form circuits when a three-way bulb is placed in the 3-way receptacle. The base includes contacts configured to come in contact with the two hot contacts and a neutral contact of the base when the base is screwed into the receptacle. The legacy lighting fixture further includes a three-way power switch to alternatively power the hot contacts. In operation the three-way switch alternatively powers the hot contacts such that the bulb is lit at three different output intensities. 
       FIG. 1  illustrates a Three-Way Bulb  100  of the prior art. Three-Way Bulb  100  of the prior art includes a Glass Cover  110  and a Base  120  configured to fit within a three-way bulb socket of the prior art. 
       FIG. 2  illustrates the three-way bulb of  FIG. 1  with the glass cover removed. This view shows a First Filament  200  and a Second Filament  210 . First Filament  200  and Second Filament  210  are supported by Leads  230 A- 230 C. 
       FIG. 3  illustrates further detail of Base  120  of Three-Way Bulb  100 . Base  120  includes three electrical contact elements. The three electrical contact elements include a neutral outer Contact Surface  310  often configured for screwing Three-Way Bulb  100  into a receptacle, a First Hot Contact  320  and a Second Hot Contact  330 . When First Hot Contact  320  is powered (e.g. a voltage is applied relative to Contact Surface  310 ) First Filament  200  is lit. When Second Hot Contact  330  is powered Second Filament  210  is lit. When Both First Hot Contact  320  and Second Hot Contact  330  are powered, both First Filament  150  and Second Filament  160  are lit. 
       FIG. 4  illustrates a legacy Three-Way Receptacle  410  and Three-Way Switch  415  configured to accommodate Three-Way Bulb  100 . Three-Way Receptacle  410  is characterized by including at least three contacts configured to make electrical connection to Contact Surface  310 , First Hot Contact  320  and Second Hot Contact  330  of Three-Way Bulb  100 . For example,  FIG. 4  shows an instance of Three-Way Receptacle  410  including an Outer Contact  420 , a Middle Contact  430 , and a Center Contact  440 . Often, Three-Way Receptacle  410  is further characterized by screw Threads  450  included in Outer Contact  420  and configured to receive Three-Way Bulb  100 . 
     Switch  210  is configured to alternatively power First Hot Contact  130 , Second Hot Contact  140 , or both First Hot Contact  130  and Second Hot Contact  140 . Various configurations of Switch  210  are known in the art. See for example, U.S. Pat. No. 551,357 to Beal or U.S. Pat. No. 712,149 to Paiste. 
     LEDs (light emitting diodes) are now available to that generate different colors of light. For example, white, red, yellow, green, and blue. These LEDs are of two general types. First, an LED that generates a fixed color (e.g., white or red or yellow). A variety of colors may be generated using more than one of these single color LEDs by powering them several at a time such that their outputs mix to produce a net light output. And Second, a multi-color LED that alone can generate more than one color responsive to voltages applied at different inputs to the multi-color LED. 
       FIG. 5  illustrates schematically several types of prior art LEDs  510 . 
     The ability to generate light of different color is an advantage of the above LEDs. However, these LEDs require special fixtures. There is a need for improved systems and methods of using these LEDs that are more convenient and practical to consumers.

     DETAILED DESCRIPTION 
     Various embodiments of the invention include a multi-mode bulb configured to generate light of two or three different colors, and/or two or three different intensities, responsive to a legacy three-way switch such as that shown in  FIG. 4 . The multi-mode bulb includes at least three electrical contacts and typically is configured to screw into a legacy three-way receptacle such as that illustrated in  FIG. 4 . 
       FIG. 6A  and  FIG. 6B  illustrate two examples of a Multi-Mode Bulb, generally designated  600 , according to various embodiments of the invention. Multi-Mode Bulb  600  includes at least a Base  610  and a Light Source  620 . 
     Base  610  includes three electrical contacts: an Outer Contact  630 , a Mid-Contact  640  and a Center Contact  650 . Outer Contact  630 , Mid-Contact  640  and Center Contact  650  are disposed to make electrical contact with a legacy three-way receptacle such that Multi-Mode Bulb  600  may be controlled by a legacy three-way switch. In some embodiments, Outer Contact  630 , Mid-Contact  640  and Center Contact  650  are configured similar to those prior art contacts shown in  FIG. 3 . Outer Contact  630 , Mid-Contact  640  and Center Contact  650  are typically configured to receive AC (alternating current) power. 
     Light Source  620  is a source of light including at least one LED (light emitting diode). In some embodiments Light Source  620  is configured to generate two or more different colors of light responsive to power applied to Outer Contact  630 , Mid-Contact  640  and/or Center Contact  650 . In some embodiments Light Source  620  is configured to generate two or more different intensities of light responsive to power applied to Outer Contact  630 , Mid-Contact  640  and/or Center Contact  650 . In some embodiments Light Source  620  is configured to generate two or more different colors of light and two or more different intensities of light responsive to power applied to Outer Contact  630 , Mid-Contact  640  and/or Center Contact  650 . In some embodiments Light Source  640  includes a laser diode. 
     In some embodiments, Light Source  620  includes at least three Leads  660 A- 660 C electronically coupled, optionally through one or more Electronic Elements  670 A- 670 C, to Mid-Contact  640 , Outer Contact  630  and Center Contact  650 , respectively. Electronic Elements  670 A- 670 C are described elsewhere herein. 
     In various alternative embodiments, Light Source  620  may include a variety of alternative LED configurations configured to produce a net light output. An illustrative subset of these alternative LED configurations is shown in  FIGS. 7A-7I . 
       FIG. 7A  illustrates an embodiment of Light Source  620  including a single LED  702 . LED  702  includes at least Leads  660 A- 660 C and two Light Emitting Junctions  704 A- 704 B. When a voltage of proper polarity is applied across either of Light Emitting Junctions  704 A- 704 B light is generated. For example, if an AC voltage is applied across Leads  660 A and  660 B, Light Emitting Junction  704 B will generate light during one phase of each AC cycle. If the AC voltage has a frequency of 60 Hz then Light Emitting Junction  704 B will generate light at 60 Hz with approximately a 50% duty cycle. Light Emitting Junction  704 A will likewise respond to an AC voltage applied across Leads  660 B and  660 C. 
     In some embodiments Light Emitting junction  704 A and  704 B are configured to generate light of different color (e.g., different wavelengths). In these embodiments, Light Source  620  will generate light of a first color when a voltage is applied across Leads  660 A- 660 B, a second color when voltage is applied across Leads  660 B- 660 C, and a third color when voltage is applied across both Leads  660 A- 660 B and Leads  660 B- 660 C. The third color will be a combination of the first color and the second color, following color combinations well know in the art (e.g., Red combined with Green gives Yellow). Thus, when Multi-Mode Bulb  600  is screwed into a legacy three-way light socket, a first setting of the legacy three-way switch will result in multi-Mode Bulb  600  generating light of the first color, a second setting of the legacy three-way switch will result in Multi-Mode Bulb  600  generating light of the second color, and a third setting of the legacy three-way switch will result in Multi-Mode Bulb  600  generating light of the third color. In some embodiments the first color is Red, the second color is Green and the third color is Yellow. In some embodiments the first color is Red, the second color is Blue and the third color is Purple. 
     In some embodiments Light Emitting junction  704 A and  704 B are configured to generate light of different intensity. In these embodiments, Light Source  620  will generate a net light output of a first intensity when a voltage is applied across Leads  660 A- 660 B, a second intensity when voltage is applied across Leads  660 B- 660 C, and a third intensity when voltage is applied across both Leads  660 A- 660 B and Leads  660 B- 660 C. The third intensity will be approximately a sum of the first intensity and the second intensity. Thus, when Multi-Mode Bulb  600  is screwed into a legacy three-way light socket, a first setting of the legacy three-way switch will result in Multi-Mode Bulb  600  generating a net light output of the first intensity, a second setting of the legacy three-way switch will result in Multi-Mode Bulb  600  generating a net light output of the second intensity, and a third setting of the legacy three-way switch will result in Multi-Mode Bulb  600  generating a net light output of the third intensity. In some embodiments the first intensity is approximately 50% of the second intensity, and the third intensity is approximately three times the first intensity. 
     In some embodiments, Light Emitting Junctions  704 A and  704 B are configured to generate light of both different intensity and different color. In these embodiments settings of the legacy three-way switch will result in both three levels of intensity and three different colors. 
     In  FIG. 7A  Light Emitting Junctions  704 A- 704 B are shown in a common cathode configuration. In an alternative embodiment (not shown) Light Emitting junctions  707 A- 707 B are in a common anode configuration. 
     In some embodiments, Lead  660 B is electronically coupled to Outer Contact  630  of  FIGS. 6A and 6B , and in-phase AC potentials are applied to Leads  660 A and  660 C. In these embodiments, Light Emitting Junctions  704 A and  704 B will generate light in-phase. In an alternative embodiment Light Emitting Junctions  704 A- 704 B do not share a common cathode or common anode. This configuration is illustrated in  FIG. 7B . In this configuration, light generated by Light Emitting Junctions  704 A- 704 B will be out of phase (assuming the above input). Typically, at 60 Hz, the difference between light generated using the configurations of  FIGS. 7A and 7B  is not perceivable to the human eye. 
       FIGS. 7C and 7D  illustrate embodiments of Light Source  620  including two separate LEDs  706 A- 706 B. In these embodiments Light Emitting Junctions  704 A and  704 B are disposed in separate LEDs  706 A- 706 B. However, by configuring LEDs  706 A and  706 B as shown in  FIGS. 7C and 7D . Light Source  602  can operate in a manner similar to those embodiments discussed above with respect to  FIGS. 7A and 7B . 
       FIG. 7D  illustrates an embodiment of Light Source  620  including LEDs  706 A and  706 B in a common anode configuration. In alternative embodiments (not shown) these LED may be in a common cathode configuration. 
       FIG. 7E  illustrates an embodiment of Light Source  620  in which LED  706 A includes two Light Emitting Junctions  708 A and  708 B and LED  706 B includes two Light Emitting Junctions  710 A and  710 B. By including two Light Emitting Junctions in an LED, the LED may be configured to generate light regardless of the polarity of input voltages. Thus, the LED may generate light on both phases of an AC signal. Otherwise the embodiments of Light Source  620  illustrated in  FIG. 7E  may function similarly to those embodiments discussed above with respect to  FIGS. 7A-7D . 
       FIG. 7F  illustrates embodiments of Light Source  620  in which LED  706 A includes two light emitting junctions and LED  706 B includes one light emitting junctions. In some embodiments, this configuration may be used such that LED  706 A generates more light than LED  706 B. Otherwise, the embodiments of Light Source  620  illustrated in  FIG. 7F  may function similarly to those embodiments discussed with respect to  FIGS. 7A-7E . 
       FIGS. 7G and 7H  illustrate embodiments of Light Source  620  wherein LED  706 A includes three light emitting junctions. These three light emitting junctions may be in various combinations of polarity (e.g., common cathode, common anode, or a mixture thereof). These three light emitting junctions are optionally configured such that their net light output is white or off-white. Thus, if for example LED  706 A is configured to generate white light and LED  706 B is configured to generate red light, then Multi-Mode Bulb  600  will generate white, red and rose (white+red) net light output responsive to settings of a legacy three-way switch. In another example, if LED  706 A is configured to generate white light and LED  706 B is configured to generate yellow net light output, then Multi-Mode Bulb  600  will generate white, yellow and a yellowish-white light responsive to settings of a legacy three-way switch. Otherwise, the embodiments of Light Source  620  illustrated in  FIG. 7G  may function similarly to those embodiments discussed with respect to  FIGS. 7A-7F . 
       FIG. 7I  illustrates embodiments of Light Source  620  that include both a conventional light generating Filament  750  and an LED  706 A. In these embodiments, Filament  750  produces the yellowish-white light normally associated with conventional light bulbs. LED  706 A is optionally used to add a color to the white light generated by Filament  750 , or to compensate for the yellowness of the light generated by Filament  750  in order to generate a whiter light than that produced by Filament  750  alone. Otherwise, the embodiments of Light Source  620  illustrated in  FIG. 7G  may function similarly to those embodiments discussed with respect to  FIGS. 7A-7H . It is further anticipated that the embodiments of Light Source  620  illustrated in  FIG. 7I  may be included in two-way bulbs (having just an on and an off state), as well as three-way bulbs. Thus, these embodiments may include only two of Leads  660 A- 660 C. In some embodiments, Filament  750  is replaced by a fluorescent light source. 
     In some embodiments the various LEDs illustrated in  FIGS. 7C-7I  are removable from Light Source  620 . Thus, an end user may change the lighting characteristics of an instance of Light Source  620  and Multi-Mode Bulb  600  by replacing one LED with another LED having different lighting characteristics. For example, a light color and/or light intensity of Multi-Mode Bulb  600  may be changed by replacing an LED. In these embodiments the replaceable LEDs may connect to Light Sources  620  using a plug or any of the many known methods of connecting an LED in removable fashion to a circuit. 
     In some embodiments Light Source  620  is removable from Multi-Mode Bulb  600 . Thus, an end user may change the lighting characteristics of Multi-Mode Bulb  600  by replacing one embodiment of Light Source  620  with another embodiment of Light Source  620 . 
     Referring again to  FIGS. 6A and 6B , various embodiments of Multi-Mode Bulb  600  optionally include Electronic Elements  670 A,  670 B, and/or  670 C disposed within Base  610  and/or Light Source  620 . Electronic Elements  670 A- 670 C may include current limiting resistors, AC/DC converters, diodes, filters, digital signal processors, timers, or the like. For example, in one embodiment Electronic Element  670 B is a resistor configured to limit the total current passing through Light Source  620  while Electronic Elements  670 A and  670 C are different resistors configured to limit the current through different LEDs. In another example Electronic Elements  670 A- 670 C are embodied in a pulse generator configured to send different pulse sequences to different LEDs within Light Source  620 . In embodiments wherein Electronic Elements  670 A- 670 C are passive elements such as current limiting resistors, Multi-Mode Bulb  600  is compatible with lamps plugged into power sources including a dimmer switch. Electronic Elements  670 A- 670 C are optionally configured such that different intensities of light are generated by different light emitting junctions within the LEDs illustrated in  FIGS. 7A-7I . 
     Referring again to  FIGS. 6A and 6B , Multi-Mode Bulb  600  optionally further includes a Support  680  and/or a Bulb Cover  690 . Support  680  is configured to hold Light Source  620  relative to Base  610 . In some embodiments Support  680  is configured to such that Light Source  620  is removable. In some embodiments Support  680  is configured to facilitate attachment of Bulb Cover  690 . For example, in some embodiments clips or threads on an Outer Surface  682  of Support  680  are disposed to match clips or threads on an Inner Surface  684  of Bulb Cover  690 . 
     Bulb Cover  690  is optionally in the shape of a standard prior art light bulb, as shown in  FIG. 6B . In various embodiments, Bulb Cover  690  is made of Glass or a non-glass material such as a polymer, plastic, cloth, polycarbonate, polyvinyl chloride, or the like. In some embodiments, Bulb Cover  690  is made of a non-breakable material. In some embodiments connections between Bulb Cover  690  and Light Source  620 , and/or between Bulb Cover  690  and Base  610  is a non-vacuum tight connection. Thus, the interior of Bulb Cover is optionally at or near atmospheric pressure. 
       FIGS. 8A and 8B  illustrate embodiments in which Bulb Cover  690  includes Fillers  810  configured to scatter or otherwise alter light generated by Light Source  620 . For example, Fillers may be colored in order to alter the color of light emitted by Multi-Mode Bulb  600 . Fillers  810  of various colors may be distributed throughout Bulb Cover  690  such that different colors are emitted from different regions of Multi-Mode Bulb  600 . In some embodiments liquid may be disposed within Bulb Cover  690 . In some embodiments Fillers  810  include nano-particles having optical properties particular to their size. In some embodiments two immiscible liquids may be disposed within Bulb Cover  690  in order to generate a Lava Lamp effect within Multi-Mode Bulb  600 . In some embodiments Light Source  620  includes a heat source and or pump configured to generate movement of these two immiscible liquids. The heat source and/or pump is optionally configured to be active in response to Leads  660 A- 660 C such that it is responsive to a legacy three-way switch. In some embodiments Light Source  620  includes a Motor  820  configured to move one or more Filler  810  within Multi-Mode Bulb  690 . For example, this motor may be configured to move an object  830  (via mechanical connection  840 ) such as a reflective surface or decorative object included as part of Filler  810 . This Motor  820  may be configured to move an object  830  within Bulb Cover  690  configured to generate a shadow on Bulb Cover  690  or external to Bulb Cover  690 . Motor  820  is optionally configured to move all or part of Light Source  620 . For example, in one embodiment Light Source  620  includes a laser, e.g., a laser diode, and Motor  820  is configured to move this laser so as to change the orientation of a laser beam originating from the laser. Motor  820  is optionally configured to move this laser to form an image using the laser beam. Motor  820  is optionally responsive to Leads  660 A- 660 C and thus responsive to a legacy three-way switch. In one embodiment, Leads  660 A- 660 C are configure such that a first setting of the three-way switch results in generation of light from Light Source  620  or a filament, a second setting of the three-way switch results in activation of Motor  820 , and a third setting of the three-way switch results in both generation of light from Light Source  620  (or a filament) and activation of Motor  820 . In some embodiments, Object  830  is configured to look like a flame when moved by Motor  820 . In some embodiments Object  830  includes a fan. 
     Further examples of fillers that may be adapted to embodiments of the invention may be found in U.S. Pat. No. 4,675,575 to Smith et al. 
       FIG. 9  illustrates embodiments of Bulb Cover  690  that includes Regions  910 A- 910 E with differing optical properties. In various embodiments the number, size, and position of Regions  910 A- 910 E may vary. Regions  910 A- 910 E may differ in their color, light transmission, material, images, or the like. For example, Regions  910 A and  910 E may be configured to pass light with a yellow color while Regions  910  may be configured to pass white light. As a result one embodiment of Multi-Mode Bulb  600  is configured to direct strong white light up toward a lamp shade or ceiling (assuming a vertical orientation or Multi-Mode Bulb  600 ) and to direct softer more yellow light down and to the side. Members of Regions  910 A- 910 E may include decorative images and/or masks configured to generate shadows. Because Bulb Cover  690  is optionally made of non-glass materials variations in light transmission, color, and other optical properties are easier to employ than with glass embodiments of Bulb Cover  690 . For example, a plastic with a color gradient or an opening in Region  910  is much easier to manufacture that the equivalent in glass. 
       FIG. 10  illustrates embodiments of Multi-Mode Bulb  600  in which Bulb Cover  690  is removable and optionally replaceable with alternative embodiments of Bulb Cover  690 . Bulb Cover  690  may be attached to Light Source  620 , Support  680  and/or Base  610  via a mechanism configured for an end user to detach and reattach. The alternative embodiments of Bulb Cover  690  may have different a different shape than the embodiment of Bulb Cover  690  illustrated in  FIGS. 6 and 10 . 
       FIG. 11  illustrates embodiments of Light Source  620  including an LED configured to be covered by a Cover  1120 . Cover  1120  is optionally of various colors and replacement of Cover  1120  therefore allows for end user modification of light generated by powering the LED. 
       FIG. 12  illustrates a Three-Way Lamp  1200  including a legacy three-way switch  1215 , a legacy three-way socket  1210 , and Multi-Mode Bulb  600 . Multi-Mode Bulb  600  is configured to support a Lamp Shade  1220 . For example, in some embodiments, Lamp Shade  1220  is supported by Supports  1230  which are optionally wire, plastic, wood, or other material sufficient to provide mechanical stability. Because the LEDs of Multi-Mode Bulb  600  do not generate significant heat, Supports  1230  may be of a material, such as wood or plastic that would not tolerate the heat of a conventional light bulb. Supports  1230  optionally come into direct compact with Cover  690  of Multi-Mode Bulb  600 . In some embodiments Cover  690  is shaped similar to a prior art filament based light bulb in order to accommodate legacy lamp shades having wire loops for Supports  1230 . In some embodiments, Supports  1230  are permanently or semi-permanently attached to Cover  690 . 
     While the discussion herein is primarily directed at Multi-Mode Bulb  600 , many of the features discussed herein alternatively apply to an LED Bulb  1300  illustrated in  FIG. 13 . LED Bulb  1300  includes Cover  690 , a Base  1310  and a Light Source  1320 . Base  1310  includes two electrical contacts, such as an Outer Contact  1330  and a Contact  1340 . Base  1310  is configured as a screw mount, bayonet mount, or the like. In some embodiments Light Source  1320  includes an instance of Light Source  620  without one of Leads  660 A- 660 C. Those features of the invention discussed elsewhere herein that do not depend on having all three of Outer Contact  630 , Mid-Contact  640  and Center Contact  650  may be included in LED Bulb  1300 . These features include, but are not limited to, those discussed herein in reference to  FIG. 7I ,  FIGS. 8A and 8B ,  FIG. 9 ,  FIG. 10 ,  FIG. 11  and  FIG. 12 . (For example, the filament/LED combination of  FIG. 7I , the fillers of  FIGS. 8A and 8B , the motor of  FIG. 8B , the regions of  FIG. 9 , the removable cover and cover material of  FIG. 10 , the LED covers of  FIG. 11 , and/or the lamp shade/cover material of  FIG. 12 , may be included in LED Bulb  1300 .) 
     Several embodiments are specifically illustrated and/or described herein. However, it will be appreciated that modifications and variations are covered by the above teachings and within the scope of the appended claims without departing from the spirit and intended scope thereof. For example the LEDs discussed herein may include diode based lasers.
