Definitions

  • This invention relates to illumination devices comprising light emitting diodes (LEDs), and also keypads that can selectively control zone, scene and show illumination among the LED illumination devices arranged among a structure based on changes to correlated color temperature (CCT) as a function of different dimcurves and brightnesses.
  • LEDs light emitting diodes
  • keypads that can selectively control zone, scene and show illumination among the LED illumination devices arranged among a structure based on changes to correlated color temperature (CCT) as a function of different dimcurves and brightnesses.
  • CCT correlated color temperature
  • Illumination devices sometimes referred to as lighting fixtures, luminaries or lamps include incandescent illumination devices, fluorescent illumination devices and the increasingly popular LED illumination devices.
  • LED illumination devices provide a number of advantages over traditional illumination devices, such as incandescent and fluorescent lighting fixtures. LED illumination devices have lower power consumption, longer lifetime, are constructed of minimal hazardous materials, and can be color tuned for different applications. For example, LED illumination devices provide an opportunity to adjust the chromaticity from red, to blue, to green, etc., or the correlated color temperature (alternatively referred to simply as "color temperature”), from warm white, to cool white, etc.
  • An LED illumination device can combine a number of differently colored emission LEDs into a single package.
  • An example of a multi-color LED illumination device is one in which two or more different chromaticity of LEDs are combined within the same package to produce white or near-white light.
  • white light LED illumination devices there are many different types of white light LED illumination devices on the market, some of which combine red, green and blue (RGB) LEDs, red, green, blue and yellow (RGBY) LEDs, phosphor-converted white and red (WR) LEDs, RGBW LEDs, etc.
  • these illumination devices can mix their chromaticity output and thereby generate white or near-white light within a wide gamut of CCTs (color temperatures) ranging from warm white (e.g., 2600K-3700K), to neutral white (e.g., 3700K-5000K) to cool white (e.g., 5000K-6000K, or daylight (e.g., 6000K-8300K).
  • CCTs color temperatures
  • Some multi-colored LED illumination devices also enable the brightness of the LED illumination device to be changed to a particular set point.
  • These tunable LED illumination devices should all produce the same color and color rendering index (CRI) when set to a particular brightness and chromaticity on a standardized chromaticity diagram.
  • a chromaticity diagram maps the gamut of colors the human eye can perceive in terms of chromaticity coordinates and spectral wavelengths.
  • the spectral wavelengths of all saturated colors are distributed around the edge of an outlined space (called the "gamut" of human vision), which encompasses all of the hues perceived by the human eye.
  • the gamut of human vision
  • colors within the gamut 10 of human vision are mapped in terms of x/y chromaticity coordinates.
  • Color points that lie on or near the blackbody curve 12 provide a range of white or near-white light with color temperatures ranging between approximately 2000K and 10,000K. These color temperatures are typically achieved by mixing light from two or more differently colored LEDs within the LED illumination device. For example, light emitted from RGB LEDs may be mixed to produce a substantially white light with a color temperature in the range of about 2300K to about 6000K. Although an illumination device is typically configured to produce a range of white or near-white color temperatures arranged along the blackbody curve 12 (e.g., about 2300K to 6000K), some illumination devices may be configured to produce any color within the color gamut triangle formed by the individual LEDs.
  • At least part of the blackbody curve 12 is oftentimes referred to as the "daytime locus" corresponding to the Kelvin scale of color temperatures of daytime.
  • daytime locus corresponding to the Kelvin scale of color temperatures of daytime.
  • a scene containing a plurality of LED illumination devices desirably has the same brightness and color temperature at a particular moment in time and thus is static for that particular scene.
  • a scene is static in terms of the illumination output (color temperature and brightness) for a period of time. Changing from one static scene to another scene to form different illumination outputs among a plurality of illumination devices within one or more zones forms what is known as a show. There may be other LED illumination devices within another scene throughout the structure that can have a different brightness and/or color temperature.
  • the illumination devices within a first scene can have a first brightness and/or color temperature
  • the illumination devices within a second scene can have a second brightness and/or color temperature.
  • the first scene can be a first illumination output from among a first group of illumination devices
  • the second scene can be a second illumination output from among the same group of illumination devices, or from a different group of illumination devices.
  • buttons on the keypad can be dedicated to change the brightness and/or color temperature of a grouped scene of LED illumination devices.
  • the brightness and/or color temperature of a grouped plurality of illumination devices that form a scene can change from a first static illumination output to a second static illumination output until such time as the button is depressed again to make further illumination output changes.
  • the change can occur by depressing buttons on the keypad at various times of day to change from one static output to another, or the change can occur automatically and at pre-defined, periodic intervals without any user intervention.
  • the automatic, periodic changes to the illumination output of a grouped scene of LED illumination devices to another illumination output of the grouped scene forms a show.
  • a dimcurve changes from, for example, a first dimcurve to a second dimcurve
  • the grouped scene of LED illumination devices can change from one show along the first dimcurve to another show along the second dimcurve.
  • scene references at least one zone containing a plurality of LED illumination devices
  • scene hereinafter also references the illumination output from the at least one zone and that output comprises a brightness and color temperature from the at least one zone at a particular point in time and that extends for a period of time until another scene having a different illumination output is produced.
  • a series of scenes along a dimcurve each possibly having different brightness and color temperature values, comprise the dynamically changing scenes that form a show.
  • a scene therefore represents not only one or more zones, but also a static brightness and color temperature output from the zones that, when automatically changed throughout the day, forms a show.
  • the target color temperatures needed to emulate the natural changes in the sun orientation to a structure containing LED illumination devices change not only as a function of brightness but also as a function of the time of day.
  • the changes in color temperatures as a function of brightness and time of day form different dimcurves that at emulated sunrise, for example, the LED illumination devices can produce 2300-2700K predominant emulated red with some yellow sunrise sky, at noontime 5000-6500K predominant emulated blue noontime sky, and again at 2300-2700 predominant emulated red sunset sky - similar to the differences between warm white, daytime/cool white, and back to warm white.
  • a scene can be assigned to a particular time of day along a given dimcurve, with other scenes having different color temperature and brightness values assigned to other times of day.
  • the desired show becomes a natural show that will automatically change the color temperature output of the LED illumination devices within a scene at a particular time of day, and among a series of scenes throughout the day, along a dimcurve that relates to the daytime locus.
  • An illumination system and method for controlling color temperature as a function of brightness.
  • the predominant feature of an LED illumination device can be the color temperature and brightness output therefrom.
  • Various forms of white are needed throughout the day to form a natural show along a dimcurve.
  • the natural show, and specifically the color temperature as a function of brightness can change to emulate the position of the sun to the structure and, more particularly, the outside daytime and nighttime natural sunlight condition.
  • An override or change to the natural show can be momentary, persistent, or permanent.
  • a keypad that is communicatively linked to a plurality of LED illumination devices arranged about a structure.
  • the plurality of illumination devices can be grouped into one or more zones within that structure, and one or more zones can be grouped to form a scene.
  • a single keypad can control one or more zones of illumination devices that are wire or wirelessly coupled to the keypad.
  • the keypad can control the color temperatures or brightness values associated with each zone, similarly.
  • the keypad can also control a scene of one or more zones of illumination devices, similarly. Control of the zone or scene can occur by depressing a button on the keypad to statically change the brightness or color temperature from one state to another. The change can remain until the button is depressed again.
  • the zone or scene can be statically controlled each time a button is depressed, until a button is depressed again.
  • a zone or scene can be statically controlled at specific times of day.
  • a series of scenes with the same plurality of LED illumination devices, but with different brightness and color temperatures, are mapped along a dimcurve to form a show, one or more of the scenes (and specifically the brightness and color temperatures of a grouped scene of illumination devices) can change in color temperature as a function of brightness and time of day.
  • Automatic and periodic changes to static illumination outputs of the same group of illumination devices can form multiple scenes with different outputs along a dimcurve.
  • scene A is a first scene of illumination devices at a relatively low color temperature
  • scene B of the first scene of illumination devices at a relatively higher color temperature increasing further to scene B of the first scene of illumination devices at an even higher color temperature, etc.
  • scene A, scene B, scene C, etc. is the same scene in terms of the group of LED illumination devices being controlled, the color temperature as a function of brightness for that group changes throughout the day so as to form different scenes since color temperature can change nonetheless among the same scene or group of illumination devices.
  • a scene not only can represent the same one or more zones (i.e., group of illumination devices) a scene also represents the illumination output of the group of illumination devices as color temperatures in relation to brightness and at different times of day to form a dimcurve having a sequence of scenes albeit from the same group of illumination devices.
  • a sunrise illumination scene can be one that produces a color temperature used to emulate sunrise condition at a specific time of day, such as an hour after sunrise.
  • a sunset scene can be a scene possibly of the same group of illumination devices but has a color temperature output used to emulate sunset conditions and thus is specific to, for example, an hour before sunset.
  • a keypad arranged among the structure is communicatively coupled to a plurality of LED illumination devices, and the keypad preferably includes a plurality of buttons arranged upon the keypad.
  • a first of the plurality of the buttons can be coupled to adjust brightness of the plurality of illumination devices within only the first zone, whereas a second of the plurality of buttons can be coupled to adjust brightness of the plurality of illumination devices within the illumination scene.

  • the static, yet modifiable color temperature and/or brightness values output from a particular illumination scene can be changed upon activation of one or more buttons on the keypad.
  • a series of scenes with different, yet each having static illumination output can be dynamically changed by stringing together over the daytime and nighttime hours and mapping the strung-together scenes to a dimcurve to form a show. That mapped dimcurve forms the natural show if the color temperatures along the dimcurve are targeted to emulate the outside daytime illumination by the sun or, during nighttime, by the absence of the sun.

  • a full brightness represents near maximum lumen value that can be output from one or more LED illumination devices.
  • the maximum brightness can be established either by the manufacturer or by a user, and therefore can be any value that can vary from manufacturer to manufacturer or from user to user.
  • a change from maximum brightness BR1 to a lessened brightness BR2 also throughout the daytime hours and possibly extending to nighttime hours.
  • the lessening of brightness can be effectuated by activating a button or a slider on, for example, a keypad.
  • the keypad would be communicatively coupled to the group of LED illumination devices affected by that keypad and, specifically, the change in brightness value can be proportional to the amount of time a button is depressed, or the distance a slider is moved. In some instances, however, the relationship between the brightness output from an illumination device is non-linear relative to actuation of a button or a slider. For example, depending on the button or slider, initial movement of the button/slider may result in a small effect on the output brightness and, as further actuation occurs the brightness increases or decreases non-linearly relative to actuation.
  • Fig. 3 illustrates another graph of different dimcurves that represent different relationships of color temperature as a function of the change in brightness shown in Fig. 2 .
  • a first dimcurve (dimcurve 1) is produced.
  • dimcurve 1 represents changing color temperature dependent not only on the full brightness BR1 value, but also on the time of day.
  • color temperature In order to emulate the position of sun relative to the structure, and the path length between the sun and the structure that contains the plurality of LED illumination devices, color temperature must change throughout the day to emulate the natural sunlight conditions produced by the sun's relative position. During sunrise and shortly thereafter, color temperature is much less than noontime local time. The same can be said for sunset.
  • the lower color temperatures emulate the more red or yellow sunrise and sunset color coordinate of the warm white color temperatures, whereas the blue color coordinate predominates the noontime blue sky.
  • the noontime blue sky approaches that of more of a natural or daytime white, rather than the warm white of the incandescent glow associated with sunrise and sunset.
  • the first dimcurve has a color temperature that peaks near noontime and decreases at times of day before noontime and after noontime.
  • dimcurve 2 As brightness decreases to, for example, BR2, as shown in Fig. 2 , a second dimcurve (dimcurve 2) shown in dashed line is formed. Like dimcurve 1, dimcurve 2 is illustrated in Fig. 3 as emulating the natural sunlight conditions surrounding the structure. Therefore dimcurve 2 also has a color temperature that peaks near noontime and decreases near sunrise and sunset.
  • the color temperature of all LED illumination devices change with brightness. However, the amount of change in color temperature depends on the color temperature at full brightness BR1. If natural sunlight emulation is to be achieved, color temperature also depends on the relative times of day. As shown in Fig. 3 , an LED illumination device producing 2300 to 2700K at sunrise or sunset times of day at full brightness (BR1) will produce a significantly lower color temperature at a lower brightness (BR2). Yet, however, the LED illumination device producing, for example, 5000 to 6500K at noontime time of day at full brightness (BR1) will produce only a slightly lower color temperature at lower brightness (BR2). The differences can be illustrated in reference to the differences in color temperatures at, for example, 5000K-6500K shown by reference numeral 14 versus the color temperature at 2300K-2700K shown by reference numeral 16.
  • Fig. 3 illustrates not only the formation of different dimcurves with changes in brightness, but also that each dimcurve has a correspondingly different relationship between color temperature and brightness.
  • dimcurve 2 demonstrates a greater change in color temperature as a function of a reduced brightness BR2 than does the color temperature change along dimcurve 1 at full brightness BR1.
  • each dimcurve represents a timed sequence of scenes, with each scene having its own color temperature as a function of brightness at a particular time of day. As different scenes are aggregated along a dimcurve throughout the day, a natural show is formed.
  • the natural show along the dimcurve 1 can be quite different from the natural show along dimcurve 2, with each dimcurve having its own relationship between changes in color temperature as a function of brightness.
  • Each dimcurve, and the associated scenes along each dimcurve have a unique color temperature relationship to brightness that is preferably different from other dimcurves so that the plurality of dimcurves that can be mapped demonstrate differing changes in color temperature in relation to brightness.
  • Figs. 4 and 5 are similar to Figs. 2 and 3 .
  • Fig. 4 illustrates that while the relative change in brightness is the same throughout the day, the absolute brightness values both in BR1 and BR2 vary throughout the day.
  • Fig. 5 indicates a resulting LED illumination device producing approximately the same difference in color temperatures among dimcurve 1 and dimcurve 2 regardless of whether the color temperature is 2300K-2700K or 5000K-6500K.
  • the similarity is shown by reference numerals 18 and 20 in Fig. 5 .
  • Figs. 3 and 5 illustrate that color temperature of a controlled group of LED illumination devices change throughout the day differently with brightness change -- either in absolute or in relative.
  • Figs. 3 and 5 illustrate that multiple dimcurves must be mapped so that when a change is made to a natural show, the appropriate change can be found within a previously mapped dimcurve and the smoothing of transition to the new natural show can occur with minimal user perception of that change, both prior to and after the change of a particular scene was made.
  • Fig. 6 two dimcurves, dimcurve 1 and dimcurve 2, are shown during daytime hours between sunrise and sunset.

Once the next timer timeout, or time of day signal is sent from the real-time clock of the keypad after the first timeout has occurred, brightness remains at the maximum value but the color temperature is increased 116. At each timed increment after sunrise when the timer times out, an increase in color temperature occurs, and the recorded maximum brightness and stepped increase in color temperature is recorded to form the first dimcurve, or dimcurve 1.
  • the next timer timeout 122 must be one that produces a decrease in color temperature 124, with a corresponding recordation of a decrease in color temperature as a function of maximum brightness along the first dimcurve 126.

  • the increasing and thereafter decreasing color temperature for maximum brightness is mapped within a table that is stored in the storage medium of each of the group of illumination devices, that group being the first group of illumination devices. If a fixed time before sunrise has not occurred 128, then the process of looking for that timer timeout continues until such time as sunset occurs 130.
  • the time of day and timer timeout is therefore reset 130 to examine again whether a fixed time after sunset 132 has occurred. If a fixed time after sunrise has occurred, then the brightness is reduced from the set maximum brightness value, as shown by block 134. The process is therefore repeated beginning at the fixed time after sunrise of increasing color temperature until a maximum color temperature is reached, and thereafter decreasing the color temperature to a fixed time before sunset, albeit for a reduced brightness, to form a second dimcurve (dimcurve 2). Accordingly, the mapped table of brightness values and color temperatures between sunrise and sunset are stored in the storage medium of the first group of illumination devices containing a first mapped table of a first dimcurve, followed by a second dimcurve. The only difference between the first and second dimcurve, however, is the reduction in brightness value, whereby the second dimcurve has a lower brightness value than the first dimcurve.

  • repetition of the program instructions set forth in Fig. 16 causes mapping of various dimcurves in a second group of illumination devices, possibly the same or different mappings with different dimcurves in the second group than the first group, and so forth.
  • Each group of a plurality of illumination devices can be different from one another within a structure, with preferably unique dimcurves associated with corresponding groups of illumination devices so as to control the natural show along one dimcurve of one group of illumination devices different from that of the natural show along, for example, another dimcurve within another group of illumination devices.

  • the mappings, or tables stored in the storage mediums of one group of illumination devices can be altogether different from the stored mappings within another group of illumination devices so as to control the natural show differently in one room from that of another since the dimcurves and scene change time intervals of each room can be different.

Therefore, if the changed, current scene is at 11:00 a.m., if there are scenes at 7:00 a.m. and 9:30 a.m. that precede the current scene, those two scenes are also changed so that the resulting dimcurve leading up to the current scene change is not disjointed, as shown in Fig. 20 , and specifically the graph 204. Subsequently, the N number of scenes after 11:00 a.m. may comprise two or more scenes as shown. However, only two subsequent scenes are changed at noon and 2:00 p.m., as shown by graph 206.

  • the graphs 204 and 206 illustrate possibly more than two scenes depending upon how far apart in time each scene is mapped along a dimcurve. For example, if a scene is mapped every 15 minutes, then N can comprise much more than 3, and can be as much as 20. Regardless of the value of N, it is important to note that not all scenes within a 24 hour period must be changed to provide smoothing. Instead, if the permanently changed scene is at 11:00 a.m., only the scenes after sunrise and leading up to 11:00 a.m., and subsequently after 11:00 a.m. to mid-afternoon need be changed.
  • the scenes after mid-afternoon, and before sunrise need not be changed since sufficient smoothing can occur in a limited number of changed scenes before and after the current changed scene.
  • the color temperature is a function of brightness before sunrise and after the middle of the afternoon will remain unchanged in the above example.
  • Figs. 6-8 when creating a plurality of scenes for the same group of illumination devices to form a first dimcurve, that process is repeated using, for example, the GUI and object oriented programming, to form multiple natural shows and corresponding dimcurves for that same group of illumination devices.
  • the process is repeated when mapping multiple natural shows and corresponding dimcurves into other groups of illumination devices.
  • the bedroom can have altogether different dimcurves and natural shows mapped in the illumination devices of the bedroom than that of the kitchen.
  • the dimcurves of color temperature as a function of brightness differs for each dimcurve regardless of the illumination devices that contain the mapped table of dimcurves.
  • it is necessary that multiple dimcurves, each having a plurality of scenes are mapped into the same group of illumination devices so as to control the color temperature differently based on changes in brightness.
  • the amount of change can depend on the color temperature at full brightness.
  • determination of previous and subsequent N scenes and the corresponding color temperature as a function of brightness for those previous and subsequent N scenes is determined depending upon whether the currently changed scene is within a pre-defined distance of a point on another dimcurve. For example, if the permanent change of the current scene is one in which brightness has been decreased, the corresponding color temperature for that current scene will no longer be on, for example, a first dimcurve 208. Instead, the current scene change caused by a reduction in brightness will result in a color temperature (CCT) that is less than the color temperature along dimcurve 208.
  • CCT color temperature
  • the changed-to, or new color temperature for the updated, and changed current scene is within a pre-defined distance of a point on a second dimcurve 210, shown in dashed line, then the scenes preceding the current scene and subsequent to the current scene are recalled or fetched from the second dimcurve 210 stored in the storage medium 56 of the group of illumination devices being controlled.
  • the second dimcurve 210 Only a portion of the second dimcurve 210 is fetched from each of the group of illumination devices being controlled, and that second portion comprises N number of scenes preceding the changed scene in N number of scenes succeeding the changed scene to provide a smooth and non-disjointed second natural show having scenes on a second dimcurve immediately preceding and succeeding the current scene, yet maintaining all of the scenes along the first dimcurve 208 before the preceding N scenes and after the succeeding N scenes.
  • the pre-defined distance of the point on the second dimcurve, shown as 212 is preferably less than 5% of the color temperature of the scene on the second dimcurve at the particular time of day for that current scene. For example, if the time of day is 11:00 a.m., and the current scene change changes from the first dimcurve 208 having a higher color temperature as a function of brightness to dimcurve 210 having lower color temperature as a function of brightness, the new current scene may not have a color temperature precisely on the second dimcurve. Instead, the current scene color temperature as a function of brightness can be within a pre-defined distance 212 of the second dimcurve 210.
  • the current scene is placed on the second dimcurve nonetheless, as well as all preceding N scenes and succeeding N scenes.
  • the color temperature along the second dimcurve at 11:00 a.m. for the current scene of the first dimcurve is 4000K
  • the second dimcurve at 11:00 a.m. the color temperature is 3800K
  • the pre-defined distance is less than 5%, or an absolute value is less than 190K, and more preferably less than 2%, or approximately 70K.
  • the value for the pre-defined distance 212 is therefore 5% of the color temperature along the second dimcurve at the particular time of day for that current scene being permanently changed. Since the first and second dimcurves are already mapped into tables placed in corresponding illumination devices any permanent change to a particular scene simply causes a selective fetching of the current and previous as well as subsequent scenes along a second dimcurve if a change is made so that it is sufficient enough to be near the second dimcurve a pre-defined color temperature distance.
  • the pre-defined distance can also be measured in terms of brightness. If the current scene change involves a change in brightness that is relatively close to a second dimcurve brightness, then the current scene will be placed on a second dimcurve along with the preceding and succeeding N scenes. That pre-defined brightness can also be 5% or less.
  • global keypad 57 comprises a singular keypad that controls the entire structure, and specifically multiple groups of illumination devices arranged throughout that structure.
  • the global keypad is arranged possibly near the entry door, or possibly near the master bedroom.
  • the global keypad comprises at least one of the plurality of buttons, and that button preferably comprises an away button.
  • the away button is used to activate a sensor to detect movement with the structure and, in response to that movement, to turn on and off an automatic periodic succession the select ones of multiple groups of illumination devices throughout a structure.
  • the turning on and turning off an automatic, periodic succession is referred to herein as a panic show.
  • the panic show will therefore override the various natural shows that can occur in different groups of illumination devices whenever, for example, a sensor detects an intruder within the structure, or within a perimeter of the structure.
  • the button on the global keypad 57 therefore can activate an away mode for detecting movement or, alternatively, when not activated, the button can enable a natural show. Therefore, depending on the state of that button on the global keypad, either a natural show of automatically and periodically changing color temperature as a function of brightness at different times of day along a selected dimcurve occurs prior to enabling the panic show when an intruder is detected. Thus, in the away mode, the natural show can continue and, when an intruder is detected, the natural show automatically changes to the panic show. Activation of the away mode to enable the natural show prior to sensing an intruder can occur through a single depression on a button and a light on the global keypad will indicate the away mode is enabled.
  • the button can enable a static scene from select ones of the multiple groups of illumination devices prior to enabling the panic show when an intruder is detected.
  • the button prior to detecting an intruder, can be illuminated to indicate an away mode, and to maintain the brightness in color temperature the same for the select ones of the multiple groups of illumination devices prior to sensing the intruder and, once an intruder is detected, the panic show is enabled.
  • the panic show can comprise turning on and off an automatic, time succession select ones of multiple groups of illumination devices throughout, as well as outside the structure, or simply initiating a change in color of the select ones of the multiple groups of illumination devices.
  • this invention is believed to provide an improved illumination system and method that not only allows mapping of dimcurves for each of multiple groups of illumination devices into the corresponding illumination devices, but also using those mapped dimcurves to allow modification of any and all natural shows throughout a structure when an intruder is detected.
  • a remote controller with a graphical user interface provides the ease by which mapping of dimcurve tables takes place, and multiple keypads assigned to groups of illumination devices allows easy momentary and persistent changes, as well as permanent changes, to the various scenes which form a natural show along the dimcurve. Further modifications and alternative embodiments of various aspects of the invention will be apparent to those skilled in the art in view of this description. It is intended, therefore, that the following claims be interpreted to embrace all such modifications and changes.
