Definitions

  • the invention generally relates to light emitting diode devices. More particularly, various embodiments of the invention relate to illumination systems and methods for controlling such systems.
  • Lighting systems that can be arranged to provide color-changing lighting effects (e. g. color-changing LED lighting systems or lighting systems with moving filters or the like). Some such systems may be arranged in a network configurations to generate coordinated lighting effects. Lighting systems to generate coordinated lighting effects typically are popular in theater lighting and are also becoming popular in other venues where color changing lighting effects are desirable. There are also color changing lighting systems that are not associated with a network. Such systems may include a number of lighting components that may not be synchronized.
  • US-5128595 describes an ornamental lighting control system capable of controllably adjusting the intensity of lights over a relatively long period of time.
  • US-4396871 describes an arrangement for digital brightness control of lamps or groups of lamps in control channels.
  • GB-A-1439924 describes apparatus for controlling the output power per channel for electrical apparatus.
  • GB-A-2029135 describes an arrangement for controlling the switching of an array of lamps connected to a multiple way output socket.
  • a lighting system comprising a plurality of non-networked lighting apparatus connected to an AC power source, each lighting apparatus, comprising: a processor configured to control a lighting effect generated by the lighting apparatus; wherein the processor is further configured to monitor a parameter of the AC power source selected from one of a periodically changing parameter of the AC power source and a transient signal of the AC power source; wherein the processor is further configured to synchronize the lighting effect in coordination with the parameter of the operating power source; and wherein the lighting apparatus comprises LED lighting apparatus and the lighting effect is generated by the LED lighting apparatus, whereby the lighting system coordinates light output from the plurality of lighting apparatus based on the parameter of the AC power source without requiring an additional coordinating signal.
  • a method of generating a lighting effect characterised by the steps of: monitoring at least one parameter of an A.C. power source provided to a plurality of non-networked LED lighting apparatus configured to generate the lighting effect, the at least one parameter being selected from one of a periodic changing parameter of the A.C. power source and a transient signal of the A.C. power source; and generating the lighting effect in synchronization with the at least one parameter whereby light output from the plurality of non-networked LED lighting apparatus is coordinated based on the at least one parameter of the A.C. power source without requiring an additional coordinating signal.
  • Applicants have recognized and appreciated that there are lighting applications in which it may be desirable to coordinate the light output of multiple light sources that are not necessarily configured in a network environment, as discussed above. For example, it may be desirable to change all the non-networked lights in a room or section of a room simultaneously so they are the same color at any one time but continually changing at a particular rate. Such an effect is termed a "color wash.”
  • a color wash might provide the following sequence: red to orange to yellow to green to blue to orange and so on. Upon power-up, all the lights may initiate the same state and the color wash may appear synchronized. If the color wash speed is relatively slow and the duration of the cycle through the wash is significant, say a minute or more, than the lights will appear synchronized.
  • one aspect of the present invention is directed to a lighting system that generates synchronized lighting effects.
  • the lighting system monitors a power source and synchronizes the lighting effects it generates with a parameter of the power source.
  • the lighting system may be attached to an A.C. power source and the lighting system may include a processor configured to execute a lighting program. The timing of the program execution may be coordinated with the frequency of the A.C. power, voltage or current.
  • the lighting system may coordinate the lighting effect with a transient parameter of the power source or other randomly, periodically or otherwise occurring parameter of the power source. This provides for a synchronized lighting effect without the need for network communication.
  • the lighting system may include one or more preprogrammed lighting effects and a user interface for selecting one of the lighting effects. Once the effect has been selected, the processor may execute the program in coordination with a parameter of the power source, causing a synchronized generation of the lighting effect.
  • a lighting system generates lighting effects in coordination with a reference value.
  • several such lighting systems may be associated with a power source and all of the systems would be coordinated with one another because they would be coordinated with a parameter of the power source. For example, you could attach several lighting systems to a power source in a hallway.
  • Each of the lighting systems may be monitoring and coordinating the execution of their lighting effects with the power source such that each of them is producing the effects in coordination with one another.
  • Each of the lighting systems may be generating a color wash and the color wash effects from each of the lighting systems will remain in sync.
  • a timing circuit configured to change the timing of the generation of a lighting effect.
  • a timing circuit is associated with a user interface such that a user can adjust the timing of the generation of the lighting effect.
  • several lighting systems may be associated with a power source in a hallway and each system may be set to a color wash effect.
  • a user may adjust the timing of each of the several systems to begin the execution of the lighting program at a different time.
  • the systems further down the hallway may be adjusted with a increasing delay such that the color wash is offset by certain amounts as the systems progress down the hall. This would result in a staggered effect, and in the case of the staggered color wash, a washing rainbow down the hallway.
  • the timing could be arranged such that, for example, as the first lighting system cycles through blue into the next color, the second system is cycling into blue.
  • the timing circuit may be provided with a substantially continuous variable timing.
  • the timing circuit may be provided with predetermined offsets of time periods.
  • Another example of a useful or desirable lighting effect that appears to pass from one lighting system to another is a "chasing effect.”
  • the chasing effect may appear to pass a red light, for example, from a first light to a second light to a third.
  • the timing of the generation of the red light may be synchronized via systems according to the principles of the present invention. So, a first light may generate red light for a predetermined time, five seconds or a number of sync cycles or the like.
  • a second light may be off (i.e. generating no effect) and following this period, the second light may generate the red lighting effect for the same period.
  • This effect may appear to propagate through many lighting systems and appear to be chasing the red light down a hallway, for example.
  • the program the lighting system is executing may generate the delay period such that it does not generate the red lighting effect until two seconds or a number of cycles have passed.
  • a user adjustable timer may be used to generate the delay. The adjustment may be used to create the appearance that it took time to pass the red lighting effect from a first lighting system to a second and so on.
  • an adjustable timing circuit may be used to compensate for phase or frequency differences in a given installation.
  • a room may be provided with several electrical outlets supplied by one phase of an A.C. power distribution system and several outlets supplied by another phase of the A.C. power distribution.
  • the timing circuit may be configured to be adjusted to compensate for the phase difference such that the timing of the lighting effects from lighting systems on the two phases are in sync.
  • the synchronization function may be used to synchronize other events as well.
  • the lighting system may be configured to generate a lighting effect at a given time and the time may be measured using the synchronization signal.
  • the several lighting systems may be programmed to change modes, into a fixed color mode for example, after they have generated the color changing effect for a period of five minutes.
  • a synchronizing signal may be generated from the peak, zero crossing, or some other parameter of an A.C. power line and this signal may be used to calculate, or measure, the five minute period.
  • the several lighting systems would stop the generation of the color changing effect and go into the fixed color mode at the same time because they would be generating the lighting effect in sync with a synchronization signal.
  • the timing, or synchronization, of events may be made in absolute time (e.g. knowing or measuring the frequency and generating a real time clock or known rate clock pulse) or the timing may be in relative measures (e.g. not knowing the real time occurrence of a parameter but synchronizing to the generation of the occurrence).
  • a system according to the present invention may be used such as indoor lighting, outdoor lighting, landscape lighting, pool lighting, spa lighting, accent lighting, general lighting, walkway lighting, pathway lighting, guidance lighting systems, decorative lighting, informative lighting, or any other area or situation where synchronized lighting effects are desirable or useful.

  • the timing circuit may be associated with a user interface to allow a user to adjust the timing as desired.
  • the adjustment may be provided as a substantially continuous adjustment, segmented adjustment, predetermined period adjustments, or any other desirable adjustment.
  • An aspect of the invention is to provide a system to adjust the cycle that each device is operating on. In effect, this adjusts the phase of the generated lighting effect such that the devices can be synchronized.
  • This can take the form of an encoder, button, switch, dial, linear switch, rotary dial, trimmer pot, receiver, transceiver, or other such device which, when turned, pressed, activated or communicated to, adjusts and shifts the part of the cycle that the device is in.
  • a button push for example, can halt the action of the device and the user can wait for another device to 'catch up' with the halted device and release at the correct part of the cycle.

  • the first illumination device may remain in sync with the AC line while a second illumination system could be set to begin the cycle thirty seconds after the first and then a third device thirty seconds after the second. This may be used, for example, to generate a moving or chasing rainbow effect in a hallway.
  • a predetermined amount may be a portion of the phase of the power waveform, such as ninety degree, one hundred eighty degree, two hundred seventy degree or other phase shift of the power waveform.
  • An illumination system may include a user interface 118 wherein the user interface 118 is used to select a program, program parameter, make an adjustment or make another user selection.

  • the user interface 118 could be used to select a synchronization mode and or a color effects mode.
  • the user interface may be a button. The button may be held down for a predetermined period to set the unit into the synchronization mode. The button could then be used to select the program to play in sync with the clock pulse. Several buttons, dials, switches or other user interfaces could also be used to accomplish these effects.
  • a power cycle could also initiate a synchronous mode or change the phase of the sync.
  • An energy storage element (not shown) could also be used (e.g. capacitor in an RC circuit) in the system to provide a high logic signal or a low logic signal.
  • the energy storage element could be associated with a power supply and with the processor in the system. When the power to the system is de-energized and reenergized within a predetermined period of time, the system could go into a synchronous mode.
  • the power cycle could also cause the phase of the execution of the program with respect to a clock pulse to be changed.

For example, if a number of nightlights or other lighting fixtures are plugged into outlets along a hallway, it may be desirable to have a rainbow move down the hallway such that the red, orange, yellow, green, blue, indigo, violet (ROYGBIV) sequence slowly moves and shifts down the hall over time. By powering up all the units in a hallway and the using the phase adjustment to select the part of a cycle to be in, the effect can be generated without additional means of communication or control.
  • Another solution is a fixed adjustment for phase control - a dial, for example, that provides a fixed setting or onboard memory that stores phase information.
  • a lighting system may include memory wherein timing, phase, adjustment or other information is stored.
  • the memory may be non-volatile, battery-backed or otherwise arranged to provide recall of the information upon re-energization of the system.
  • Phase adjustment can be accomplished through a button, for example, that is added to the device that allows the user to press and stop the effect until another light fixture 'catches up' with the current display. In this way, only one other light needs to be visible to any other to allowing synchronization when a user is accomplishing the task by him or herself.
  • Another mode is to allow a 'fast-forward' of the display until it catches up to the reference display. When the two are at the same point in the sequence then the button is released and the two will remain in synchronization from that point on.
