Description of the Invention: [Technical Field] The present invention relates to a control device for an illumination source and an illumination system including such a control device. The invention is also directed to a corresponding method. [Prior Art] Recently, great progress has been made in increasing the brightness of light-emitting diodes (LEDs). Therefore, LEDs have become sufficiently bright and inexpensive to be used, for example, in lighting configurations such as lamps with adjustable colors. -light source. By mixing LEDs of different colors, many colors, such as white, can be produced. An adjustable color illumination system is typically constructed by using a number of primary colors, and in one example three primary colors are used: red, green, and blue. The color of the light produced is determined by the LEDs used and the mixing ratio. $ produces "white" and all three LEDs need to be turned on. By using LEDs, energy consumption can be reduced, which is quite in line with current environmental trends. To further reduce the energy consumption of the illumination configuration, a photosensor and presence detector can be included to detect changes and proximity of ambient illumination, respectively. The addition of the two can in turn lead to a reduction in the illumination configuration time and a reduction in intensity by considering ambient illumination. In an illumination system comprising a plurality of the above illumination configurations, a potentially useful illumination and illumination arrangement - including a hardware component to allow for some communication between different illumination configurations - thereby further reducing energy consumption. To this end, several wireless technologies have been developed, including, for example, a lamp transmission circuit supporting IEEE 802.11. However, a problem with such wireless technologies is that they have led to a significant increase in the cost of the configuration and thus have resulted in a substantial increase in the cost of the resulting lighting system. It is therefore necessary to improve the communication between lighting configurations in a lighting system and, more particularly, to overcome or at least mitigate the prior art problems associated with expensive additional hardware components. SUMMARY OF THE INVENTION According to one aspect of the present invention, the above problem is achieved by a control device for an illumination 0 light source, the control device comprising: a light sensor for detecting one a visible light illumination characteristic; and a control circuit adapted to select at least one of a plurality of predetermined visible light illumination characteristics based on a signal received from the light sensor and output a corresponding one of the selected at least one illumination characteristic A control signal to control the illumination source 0 The general concept of the invention is based on the fact that the actual illumination characteristics of one of the illumination sources can also be assigned using the actual visible illumination of an indoor and/or outdoor environment. That is, the control device of the present invention permits detection of one of the surrounding current characteristic states of the surroundings, and controls an illumination light connected to the control device such that the illumination source produces a predetermined illumination characteristic that is different from the extracted state. Thus, two different control devices, e.g., connected to two different light sources, can know each other without resorting to complex rf communication techniques. The control device of the present invention only needs to detect the light illumination characteristics around it and respond by emitting light according to at least some of the predetermined visible light illumination characteristics. For example, the selected at least one visible illumination characteristic may be different. The illumination characteristics detected by the light sensor. 144770.doc 201029517 The advantage of the present invention is to reduce energy consumption and improve lighting quality and perceived comfort. As mentioned, since no data is transmitted, but only the state of the illumination source is transmitted, it is not necessary to include hardware (4) (4) for RF communication. More specifically, an additional communication channel through which different information is not required is provided, and instead, the illumination characteristics of the light emitted by the illumination source are sufficient. In an embodiment, wherein the control signal is encoded by the control circuit such that the selected at least one visible illumination characteristic is modulated to include a frequency component. By such an embodiment, the illumination source can be controlled by using pulse width modulation (PWM). The PWM can be used to control the brightness/intensity of the illumination source, but can also be used to modulate the emitted light in accordance with the present invention, which in turn can: light. In a preferred embodiment, the control device further includes means for detecting A sensor in the name of a moving object (such as an approaching person or an approaching vehicle). This can be done via IR, Ultrasound or any other similarity: complete. In this case the 'control signal may be controlled by the control circuit' to cause at least one of the visible illumination characteristics selected by the transmission to be modulated for signalling the presence of the moving object. Therefore, it is possible to improve the lighting quality. Actually, you can achieve more than one "follow me" in this way by |j. "Follow me" can be achieved by a simple (off-the-shelf) lighting fixture with a presence detector. · All lights in your place are turned on. However, the 4th of the proposed pair has an effect on where you are. This results in a :::" behavior. Therefore, it is possible to provide more comfortable lighting by providing a "5|guide me" behavior. For example, the illumination can be configured to follow the object 144770.doc 201029517 ' without having to use, for example, a switch. In an alternate embodiment, if the number of people is moving, the light output can be gradually changed to avoid rapid changes. Furthermore, a time delay may be included, wherein the control device of the present invention presages that the illumination is specific and only begins after a certain phase delay (eg, 'the phase delay may depend on the illumination characteristics of the _) - the response illumination Feature 2 This method can send a "light wave" on a street and/or corridor without people. Moreover, in an alternative embodiment, if there are several objects in the space: "such as a person or a vehicle" moving, the light output can be gradually changed to avoid. Different types of visible light illumination characteristics can be provided, for example, including emitting light having a predetermined intensity, emitting light having a predetermined color, and/or emitting light having a predetermined beam width. Therefore, as an example, red light and blue light can be measured. In addition, the control circuitry can be provided with additional functionality to advance by, for example, using the previously selected visible light illumination characteristics and selecting the currently selected visible light illuminations in selecting at least one of the currently visible illumination characteristics. Improve lighting quality. From a general point of view, lighting can include floodlighting, indirect lighting, and multi-point lighting. The control device can be provided as a separate unit' but can also be incorporated into or included with a lighting fixture. Furthermore, in order to achieve a high energy '1 efficiency, the light source is preferably selected from the group consisting of: a light emitting diode (LED), an organic light emitting diode (0 LED) 'polymer light emitting diode (PLED) ), inorganic LED, cold cathode fluorescent lamp (CCFL), hot cathode fluorescent lamp (FL), electric public light. As is known above, the conventional bulb "LEd" which transmits power up to about 6% in light form has a much higher energy 144770.doc 201029517 efficiency. Of course, the skilled artisan will appreciate that a standard incandescent source such as an argon source, a xenon source and/or a xenon source can be used. In an even better embodiment, the light source can, for example, comprise a combination of at least some of red, green, blue, yellow, magenta, and cyan LEDs to create a hybrid color illumination. However, one or a plurality of white LEDs can also be used. Further combinations are also possible. The lighting fixture can also further include means for adjusting the beam width of the light emitted by the visible illumination source, which can be controlled by the control circuitry based on the selected illumination characteristics. Additionally and as discussed above, a plurality of control devices can be configured to cause the lighting devices connected to the plurality of control devices to know each other's status. As @, a lighting system comprising a plurality of lighting fixtures and each lighting fixture comprising a control device of the invention may be provided. According to another aspect of the present invention, a method for controlling a visible illumination source is provided, the method comprising: detecting a visible light illumination characteristic; selecting at least one of a plurality of predetermined visible light illumination characteristics; and providing a corresponding A control signal of the at least one illumination characteristic is selected to control the illumination source' wherein the selected at least one of the illumination characteristics is different from the illumination characteristic detected by the photosensor. With this aspect of the invention, energy consumption and improved illumination quality can be further reduced in a similar and similar manner as described above with reference to the first aspect of the invention without resorting to complex and expensive RF communication techniques. Further features and advantages of the present invention will become apparent upon a study of the appended claims.

The first sensor 1〇8 can be a photodiode, and the second sensor 110 can be provided for detecting the area around one of the control devices 102 using IR, ultrasonic or any other suitable method. A similar function of the moving object - the sensor. For example, the area may be approximately the same as the area illuminated directly by the lighting fixture 100. Instead of using the second sensor m, the adaptive control circuit can receive information about the moving object from, for example, a camera (not shown). In the picture! The control device 1〇2 is discussed as being included in the lighting fixtures. However, the functionality provided by the control device 1〇2 can also be applied to the visible illumination source 104 and, for example, a lamp holder (the device 102 can also include light for the absence of a seat, which can be illuminated by the illumination source 104).

As discussed above, each of the lighting fixtures 100a-100e includes one of the control devices 102 of the present invention and at least one visible illumination source. 4. At some point in time, the person 202 has moved so that he/she is under the lighting fixture 丨〇〇c and is detected. In this case, the lighting fixture 100 (provided to have a first optical characteristic) Light, for example, where the lighting fixture 100c is issued There is a maximum intensity level of white light. As a result, the lighting fixtures 10b and 100d disposed relatively close to the periphery of the lighting fixture 100c detect the light of the lighting fixture 100c and are illuminated by, for example, but not limited to, a different light. The characteristic (eg, light having a level of intensity lower than the intensity level of the light emitted by the lighting fixture 100c) is responded to. The result 'lighting fixtures l〇〇a and l〇〇e detecting the lighting fixtures 1〇〇1) and l 〇〇d light and then respond with different light characteristics (for example by emitting light having an even lower intensity level). If the person 202 is moving in a direction closer to the lighting fixture 1 〇〇d (as illustrated in Figure 2b), he/she can be detected not only by the lighting fixture 1 but also by the lighting fixture 100d. In response to this, the lighting fixture 100d can, for example, Increasing its light intensity level to an intensity level similar to the level of light intensity emitted by the lighting fixture 丨〇〇c.

If the person 202 moves further in the same direction (i.e. toward the lighting fixture 100e), it may occur in a manner similar to the intensity level offset just described. An additional intensity level offset. In a preferred embodiment, as the distance to the person 202 increases, the intensity level of the lighting fixture 1 变 becomes smaller, thereby illustrating that 144770.doc 201029517 is achievable by the present invention. The "Guide Me" feature discussed above. In another preferred embodiment for, for example, outdoor lighting, the intensity (d) has a lower limit to avoid fearful dark areas. The first sensor (10) can also be used to cause the lighting fixture to emit a minimum intensity level of light depending on the background illumination level (e.g., this may occur due to a neon change). In this way, system 200 can save even more energy. In addition, if more than one lighting fixture detects the presence of one person 2, 2, then all of the lighting fixtures (10) of the person are configured to emit a || light having a "maximum intensity level." In order to easily transmit a particular illumination characteristic, the light emitted by each of the lighting fixtures L 100e can be encoded as described below. The encoded visible light is then detected by a device 100 (e.g., similar to pWM) around the lighting fixture 100 that emits the encoded light. In one embodiment, the illumination features are transmitted using a frequency modulation of the emitted light. For example, if the presence of a 戎 徊 徊 徊 徊 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人 个人If no (4) one is detected and only light from adjacent lighting fixtures 100 is detected, then the rate of light can be doubled or (more generally) varied at a second unique frequency. Instead of doubling the frequency, it may be useful to utilize a small column of unique frequencies. 0^#^(beat frequency)^ (harmonic frequency)^ ^ is the part of the list and can be from m, so the phase (four) doubles the frequency. The advantage of using the -: column unique frequency is that the variation of the frequency of an incorrect assignment is small. In an exemplary embodiment, a set of frequencies can be selected, f 2, f 2, · ρ J and ι i, , x. It should be noted that the frequencies fl, f2, f3 can be any frequency, for example (7) 144770.doc • 12_ 201029517 kHz 130 kHz, 7.4 kHz. It is said that the lighting fixture of the moving object will emit light having a frequency η independent of any light. None (4) to - one of the objects of the lighting fixture searches for any light with frequency _^2, 〇, ^. The lighting device will detect that the frequency of the frequency is one level lower than the highest level frequency detected, for example, if the lighting device detects fi and f2, then it will Issue f2. For example, if it only detects sensation, it will emit a specific lighting fixture (10) that emits light modulated at frequency fl.

Switching the appliance to a lower level of modulation frequency 'may provide a lower intensity level, which means that if no other light is active, the lighting fixture will automatically shut off after several alternations. In addition, the light output of the lighting fixture is a function of the frequency of the lighting fixture. The lamp having the lowest frequency in a preferred embodiment results in the most southerly wheeling. If the inferred light has a frequency above a certain frequency fmax, the resulting light output is zero or fixed at a certain level. In the latter case, a minimum amount of illumination is ensured. Additionally, a second operational scenario of a lighting system 2 is provided in FIG. The dogman is similar to Figure 2, the lighting system, including a plurality of lighting fixtures, but illustrated in Figures 3a and 3b, if the person 2〇2 moves from a first room to the door by opening a door - The situation in the second room. In Fig. 3 &, the person 2〇2 is in the first room and is only detected by the lighting fixture 1〇〇c. Lighting fixtures 1 and io〇b respond as described above with respect to Figure 2. The lighting fixtures 10(10)d and l〇〇e did not detect anything (because the door was closed) and therefore did not make 144770.doc -13- 201029517 〇 but 疋, right man 202 opened the door (see Figure 3b), Then, the lighting fixture 1〇〇d measures the light of the lighting fixture 1GGc, and the lighting fixture responds with light emitting a predetermined lighting characteristic corresponding to the measured illumination characteristic. As a result, and as discussed with respect to Figure 2, the lighting fixture 1 6 will respond to the lighting characteristics emitted by the lighting fixture. In addition, if the person 202 continues to move, and thus moves into the second room and closes the door, the lighting fixtures 100a, lb, and l00c may be turned off, or the light output thereof may be reduced to a predefined minimum level. Even though the invention has been described with reference to specific exemplary embodiments thereof, many variations, modifications, and the like are apparent to those skilled in the art. For example, control circuitry 116 may include storage means for storing previously selected lighting characteristics. That is, if a lighting fixture 100 reacts with a specific lighting characteristic, the lighting fixture 1 can be adapted to change its lighting characteristics to another different lighting characteristic (for example, causing the lighting fixture 1 to emit A stepwise or continuously variable change in the intensity level of the light). Furthermore, the detected illumination characteristic indicates that the object is moving away from the lighting fixture, so that the lighting fixture 100 can be configured such that it is illuminated by the lighting fixture i The intensity level of the emitted light is reduced at a faster rate than one of the normal speeds of the reduced intensity level. In addition, as long as the appliance 1 〇 〇 may become blind (not functioning) for a predefined period of time, it is possible to properly cut off a self-contained sequence. Variations of the disclosed embodiments can be understood and effected by the skilled artisan in the practice of the invention.
