DETAILED DESCRIPTION
FIGS. 1 and 2 are prior art Figures. FIG. 1 shows a luminaire 1 with an integral controller or input device 2 that allows an operator to switch, dim, or otherwise modulate the luminaire lamp or ballast via a manual actuator, knob or slider integral to the luminaire. Such luminaires typically operate as stand-alone units. FIG. 2 shows a luminaire 3 with a low-voltage receptacle or port 4 configured to accept a plug-in cable 5 from a remote controller, input device, and/or control network 6 capable of switching, diming or otherwise modulating the luminaire independently or in concert with other luminaires. Such control networks may be based on electrical (wired) or radio-frequency (wireless) communications.
Referring now to FIGS. 3-6, there is disclosed is a illumination system 10. This system 10 shown allows a singularly configured luminaire to interface with multiple control strategies and facilitate the conversion of the luminaire from one control strategy to another. However, embodiments of the invention are not limited to those disclosed in these descriptions and the referenced figures. One skilled in the art will conceive others.
Referring now to FIGS. 3 and 4, the system 10 includes a luminaire 11, a lamp and/or ballast 12, a luminaire housing 16, first control input 14 integral or at least partially internal to the housing 16, and a plug-in port 18 defined by the housing 16. The control input 14 is connected to the port 18 via output components 20, and the lamp or ballast 12 is connected to the port 18 via input components 22.
Also disclosed is a first removable plug-in device 24 that, when inserted into the port 18, electrically connects the control input 14 to the lamp or ballast 12 via input components 22 (see FIG. 3). In an exemplary embodiment, the control input 14 might be a voltage potentiometer and the ballast might be a fluorescent 0-10V analog dimming ballast whereby the potentiometer is used to vary the ballast output. In the exemplary embodiment of FIG. 3, when the plug-in device 24 is removed, the integral control input 14 is disconnected from the lamp/ballast.
As is shown in FIG. 4, when the plug-in device 22 is removed from the port 18, the port 18 becomes available for insertion of another plug-in device 26. When the plug-in device 26 is inserted in the port 18, the lamp or ballast 12 may be connected to a second control input 28 via input components 22. This second control input 28, which may a network, computing resource, or manual actuator, is disposed externally of and remote to the luminaire 11. The plug in device 26 may associate the control input 28 with the port 18 and input components 22 via a plug-in cable 30 such as that shown in the embodiment of FIG. 4. In another exemplary embodiment (not shown), the plug-in device 26 may communicate with the input control 28 without presence of the cable 28. In such an embodiment, the plug-in device may simply be receptive to wireless signals (RF, etc.) from the input control 28.
It is important to note that, in the exemplary embodiment of FIGS. 3 and 4, the luminaire 11 can be converted back to stand-alone operation by removing the plug-in 26 from the port 18, and re-inserting the plug-in device 24.
Referring now to the exemplary embodiment of FIG. 5, another plug-in device 32 is disclosed. This plug-in 32 electrically links the internal control input 14 to dimming ballast as described above, and additionally incorporates a resistor 34. Dimming ballasts (for example analog dimming ballasts) produce a voltage potential across their control connections and vary lamp output according to the operating signal loop impedance/current. This allows the plug-in device 34 to establish a minimum impedance that effects a minimum dimming level by altering communication between the output components 20 and input components 22. Plug-in devices with a variety of impedance ratings are conceived, allowing the minimum dimming level to be selected according to the plug-in device is inserted into the luminaire plug-in receptacle.
Referring now to the exemplary embodiment of FIG. 6, the external input device 28 communicates input device 14 via a plug-in 36. In this exemplary embodiment, which allows simultaneous connection of the lamp or ballast 12 with input control 14 and input control 28. The external input device 28 arbitrates this input with other wired and RF inputs. It then delivers a corresponding control signal response to the ballast(s) or lamp(s) via the same plug-in 36, port 18 and input components 22. It should be appreciated that this arrangement allows that some or all external wired and/or wireless inputs received at the external input device 28 might override, augment, or otherwise modify the communication between the integral input device 14 and the lamp/ballast 12. Likewise, this arrangement allows that some or all inputs to the integral input device 14 might override, augment, or otherwise modify the communication between the external input device 28 and the lamp/ballast 12.
Again, it is important to note that, in the exemplary embodiment of FIGS. 5 and 6, the luminaire X can be converted back to stand-alone operation by removing the plug-in 26 from the port 18 and re-inserting the plug-in device 32. In addition, the plug-in device 36 (like 26) may communicate with the input control 28 without presence of a cable. In such an embodiment, the plug-in device may simply be receptive to wireless signals (RF, etc.) from the input control 28.
Although not shown in the attached figures, a similar plug-in device is conceived whereby, when inserted into the plug-in port, the plug-in devices may communicate wirelessly with the output components of the integral input device 14, the external input device 28 and the input components 22 of the luminaire rather than communicating via wired connections or cables.
Referring now to FIGS. 3, 5, and 6 in particular, it should be noted that each of the plug-ins 24, 34, and 36 include at least one input 40 receptive to communication with the control input 14. Each of the plug-ins 24, 32, and 36 also include at least one output 42 that is communicable with the lamp or ballast 12 via connections 44.
With more specific reference to the various plug-ins, it should be noted that plug-in 24 and 32 are configured to connect the lamp or ballast 12 to the control input 14 only, while plug-in 26 is configured to connect the lamp or ballast 12 to said second control input 28 only. On the other hand, plug-in 36 is configured to simultaneously connect the lamp or ballast 12 to the control input 14 and the control input 28.
While the invention has been described with reference to an exemplary embodiment, it should be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or substance to the teachings of the invention without departing from the scope thereof. Therefore, it is important that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the apportioned claims. Moreover, unless specifically stated any use of the terms first, second, etc. do not denote any order or importance, but rather the terms first, second, etc. are used to distinguish one element from another.
