Description of the Invention: [Technical Field] The present disclosure relates to a dimming control device and method thereof, and relates to a dimming control device and a method thereof suitable for a light-emitting diode lamp. [Prior Art] Light Emitting Diode (LED) related technology is currently the main research and development direction in the world. 'The goal is to replace the traditional photo φ Ming' to overcome the development bottleneck and future of LED. 'It will not be just Consider simply designing as a summary. Due to the attention paid to the development of related technologies, LED lighting that promotes energy conservation and environmental protection has added new added value. Therefore, LED lights are no longer simply bright or dark. In line with the current energy saving, the lighting will save energy, dimming design and situation lighting. It will be a very important part of the LED lighting market. A lighting fixture needs to be equipped with a control unit and an LED luminaire. When applied to a home and requires overall dimming control environment lighting, if each luminaire is equipped with a separate dimming unit, the cost φ would be a very Big burden. On the other hand, lighting control systems, such as DALI (digital addressable lighting interface), DMX, etc., have limitations on the number of addressing controls. For example, DALI can only control 64 groups of light sources or lamps. The modular LED luminaires are the design trend. At the same time, there are often many light source modules. Modular LED luminaires, combined with digital dimming systems, require individual control of different light source modules, which can take several times more control units, increasing the cost of the overall lighting system. Therefore, if the cost burden can be reduced, it will help the LED lighting system to be used more widely. 201208484 SUMMARY OF THE INVENTION The present disclosure relates to a dimming control apparatus and method thereof, which can perform individual address dimming of different lamps by decomposing or allocating a plurality of sub-dimming commands using a dimming command. In this way, the circuit complexity of the implementation of the dimming control device is greatly simplified, and individual address dimming of multiple LED modules can be performed. The installation cost of the lighting system will be reduced, and the LED lighting system will be used more widely, helping to save energy and benefit the environment. According to a first aspect of the present invention, a dimming control apparatus is provided, comprising a control unit and a dimming drive unit. The control unit responds to a dimming command and a load amount, and demultiplexes the dimming command into a plurality of sub-dimming commands corresponding to the number of loads according to the number of loads. The dimming driving unit has a plurality of output ends, and is adapted to be coupled to the complex array luminaire, wherein the control unit controls the dimming driving unit by using a sub-dimming command, so that the dimming driving unit outputs a plurality of dimming driving signals corresponding to the luminaire To individually control the brightness of each group of lamps. According to a second aspect of the present invention, an illumination system is provided comprising a dimming control device, a complex array lamp, a dimming command input unit and a load amount setting device as described above. The lamps are respectively coupled to the dimming drive unit of the dimming control device. The dimming command input unit and the load quantity setting device are respectively coupled to the control unit of the dimming control device to respectively input the dimming command and the load amount. According to the third aspect of the present invention, a dimming control method is proposed for adjusting the brightness of a complex array of lamps. The method includes: a. Responding to a dimming command and a load amount, and decomposing the dimming command according to the number of loads 201208484 TW6446PA 'is a plurality of sub dimming commands corresponding to the number of loads. b. According to the sub-dimming command, a plurality of dimming driving signals are generated, and these dimming driving signals are used to individually adjust the brightness of the lamps. In order to better understand the above and other aspects of the present invention, the following detailed description of the embodiments, together with the drawings, will be described in detail as follows: [Embodiment] Embodiments relate to a dimming control device and a method thereof, Different luminaires can be individually addressed and dimmed by using a dimming command to decompose or assign multiple sub-dimming commands. The LED luminaires are exemplified below, and other suitable luminaires are also available. First Embodiment Referring to Figure 1, there is shown an illumination system using a dimming control device in accordance with a first embodiment. As shown in FIG. 1, the illumination system 10 includes a dimming control device 100 and at least one set of LED lamps L1 to LN, where φ N represents the number of groups of LED lamps, and N2 1, in this embodiment, a plurality Group LED lamps are described, but not limited to this. The dimming control device 100 responds to a dimming command C and the number of loads K, and generates K addressable sub-dimming commands to correspond to the K groups of LED lamps to individually perform independent dimming control on the K groups of LED lamps, such as The switch control is 0 or 100% dimming, so that it has a dimming resolution of 0 to 100%. The dimming control device 100 outputs the dimming driving signals of the corresponding K groups of LED lamps according to the K addressable sub-dimming commands to individually control the brightness of the K groups of LED lamps. It should be noted that each group of LED lamps can contain one or more LED lights 201208484
------ » I 具，並不以此為限。也就是說，若同一組的LED燈具具有 複數個LED燈具時，當接收到調光驅動訊號後，這些複數 個LED燈具會具有相同的明亮度。此外，負載數量K應大 於或等於LED燈具之組數N，以使調光控制裝置100能夠 單獨控制每一組LED燈具L1至LN。在本實施例中，將以 負載數量K等於LED燈具之總數N (即調光控制裝置100 能夠單獨控制每一組LED燈具L1至LN)的情況來做說明， 但並不以此為限。 調光控制裝置100例如可實施為包括一控制單元110 以及一調光驅動單元120。控制單元110，用以對調光命 令C作分配及據以控制調光驅動單元120。控制單元110 接收調光命令C及得到負載數量K，並依據負載數量K將 將調光命令C分解為相應於負載數量K之K個可定址的子 調光命令。調光驅動單元120具有複數個輸出端，適於耦 接至複數組LED燈具L1至LN。控制單元110利用子調光 命令以控制調光驅動單元120，使調光驅動單元120據此 輸出對應的K組LED燈具之調光驅動訊號，以個別的控制 K組LED燈具。換句話說，每一組LED燈具之調光驅動訊 號係用以個別地調整耦接到與其對應之調光驅動單元120 之複數個輸出端之一的一組LED燈具的明亮度。亦即調光 控制裝置100能達到可定址的調光功能。 舉例而言，調光命令C具有複數位元M(M22)，如為 一 8位元的命令。當K為8時，代表調光控制裝置100可 用以驅動8組LED燈具L1至L8，此時調光命令C的8位 元，例如表示為C = B7B6B5B4B3B2BlB。，即由控制單元1 1 0分 201208484 TW6446PA ’ 解為8個子調光命令’且分別由Bo、Bl、B2、B3、β4、、 Be、Β7所代表，以分別對應到8組LED燈具L1至L8。調 光驅動單元120依據上述8個子調光命令，輸出對應的8 組LED燈具之調光驅動訊號，以個別的驅動這8組led燈 具。在此例子中，因為每組LED燈具只由1個位元控制， 例如LED燈具L3，由B2來控制，所以只有〇或ι〇〇%的調 光，即開或關兩種狀態。又例如，當K為2時，代表調光 控制裝置100可用以驅動2組LED燈具L1及L2。此時調 鲁光命令C的8位元’即由控制單元11〇分解為兩個子調光 命令，分別由B3B2BiB。及ΒϊΒδΒδΒ4所代表，以分別對應到兩 組LED燈具L1至L2。調光驅動單元120依據上述兩個子 調光命令，輸出對應的兩組LED燈具之調光驅動訊號，以 個別的驅動這兩組LED燈具。在此例子中，因為每組led 燈具由4個位元控制’例如LED燈具L2，由B7BeB5B4來控 制，所以明亮度從0至1〇〇%的調光解析度中有24即16階 數之調光變化。也就是說，控制單元110依據負載數量κ 來將調光命令C的Μ位元分解為相應於負載數量κ之子調 光命令，使每一子調光命令具有至少一位元數，其中，每 一組LED燈具之明亮度從〇至1〇〇%的調光解析度是由相對 應的子調光命令之位元數來決定。 此外，要說的是，負載數量κ並不代表LED燈具之組 數Ν’虽K為8時，其實際耦接至調光驅動單元12〇之lED 燈具之組數N可以為1〜8組，此時每組LED燈具由1個 位70控制，並不以上述列舉為限。 另外’上述調光控制裝置100以及調光信號C可以設 201208484 计為適合其他位元數如10、16或其他位元，即又可擴充 可定址的子調光命令的數目以及可以調光的階數。 如上述的舉例可知’應用一調光信號命令c，分解成 多個可定址的子調光命令，以個別驅動多組LED燈具，其 能大大地降低調光控制所需的電路複雜度以及所需要的 數量’如此可以大幅節省LED照明控制系統的佈建費用。 此外’上述照明系統10亦可帶來許多實作上的彈性， 例如調光命令C及負載數量K的輸入，可以隨著應用的需 求具有不同的實施態樣。例如第1圖所示，可以設計一負 載數量設定裝置150，如類比、數位或機械式開關或其他 電路，用以輸入負載數量K。此外，照明系統1〇可設計為 利用一調光命令輸入單元160，如遙控器或控制面板，用 以輸入調光命令c。藉由負載數量設定裝置150及調光命 令輸入單元160分別耦接至調光控制裝置1〇〇之控制單元 110中，以分別輸入調光命令c及負載數量κ。當然，負 載數置设定裝置150及調光命令輸入單元ι6〇又可實現為 一整合的輸入裝置。此外，在一例子中，為了提供方便性 及系統化的官理，調光命令輸入單元16〇可實施為一運算 裝置如電腦、手持裝置、手機，透過串列或並列通訊方式 以傳輸調光命令C到調光控制裝置100，並且可延伸加以 程式化的調控或排程。在另一實施態樣中，又可實現調光 控制裝置100為具有-種有線或無線的通訊界面或通訊模 =(如1232、腿、藍牙或Wi_Fi)，或是經由網路，以 達成近或运端的控制調光控制裝置。 以下將舉例說明調光控㈣置刚的其他實施方式。------ » I, not limited to this. That is to say, if the same group of LED lamps have a plurality of LED lamps, the plurality of LED lamps will have the same brightness when receiving the dimming driving signal. Further, the number of loads K should be greater than or equal to the number N of LED lamps to enable the dimming control device 100 to individually control each group of LED lamps L1 to LN. In the present embodiment, the case where the number of loads K is equal to the total number N of LED lamps (i.e., the dimming control device 100 can individually control each group of LED lamps L1 to LN) will be described, but not limited thereto. The dimming control device 100 can be implemented, for example, to include a control unit 110 and a dimming driving unit 120. The control unit 110 is configured to allocate the dimming command C and control the dimming driving unit 120 accordingly. The control unit 110 receives the dimming command C and obtains the number of loads K, and decomposes the dimming command C into K addressable sub-modulation commands corresponding to the number of loads K according to the number of loads K. The dimming drive unit 120 has a plurality of outputs adapted to be coupled to the complex array of LED luminaires L1 to LN. The control unit 110 uses the sub-dimming command to control the dimming driving unit 120, so that the dimming driving unit 120 outputs the dimming driving signals of the corresponding K groups of LED lamps to individually control the K group LED lamps. In other words, the dimming drive signals for each set of LED luminaires are used to individually adjust the brightness of a set of LED luminaires coupled to one of the plurality of outputs of their corresponding dimming drive unit 120. That is, the dimming control device 100 can achieve an addressable dimming function. For example, the dimming command C has a complex bit M (M22), such as an 8-bit command. When K is 8, the representative dimming control device 100 can be used to drive the eight sets of LED lamps L1 to L8, and the 8-bit of the dimming command C at this time is, for example, expressed as C = B7B6B5B4B3B2B1B. , that is, by the control unit 1 1 0 points 201208484 TW6446PA 'solved as 8 sub-dimming commands' and represented by Bo, Bl, B2, B3, β4, Be, Β7, respectively, to correspond to 8 groups of LED lamps L1 to L8. The dimming driving unit 120 outputs the dimming driving signals of the corresponding eight groups of LED lamps according to the above eight sub-dimming commands to individually drive the eight groups of LED lamps. In this example, because each group of LED luminaires is controlled by only one bit, for example, LED luminaire L3, controlled by B2, there is only 〇 or ι〇〇% dimming, that is, two states. For another example, when K is 2, it means that the dimming control device 100 can be used to drive the two sets of LED lamps L1 and L2. At this time, the 8-bit element of the Luguang command C is decomposed into two sub-dimming commands by the control unit 11〇, respectively, by B3B2BiB. And ΒϊΒδΒδΒ4 are represented to correspond to the two sets of LED lamps L1 to L2, respectively. The dimming driving unit 120 outputs the dimming driving signals of the corresponding two sets of LED lamps according to the above two sub-lighting commands to individually drive the two sets of LED lamps. In this example, because each set of led luminaires is controlled by 4 bits 'for example, LED luminaire L2, controlled by B7BeB5B4, there are 24 or 16 orders of brightness in the brightness resolution from 0 to 1〇〇%. Dimming changes. That is, the control unit 110 decomposes the unit of the dimming command C into the sub-dimming commands corresponding to the number of loads κ according to the number of loads κ, so that each sub-dimming command has at least one bit, wherein each The dimming resolution of a group of LED luminaires from 〇 to 1〇〇% is determined by the number of bits of the corresponding sub-dimming command. In addition, it should be said that the number of loads κ does not represent the number of LED lamps. When the K is 8, the number of groups N of the lED lamps that are actually coupled to the dimming drive unit 12 can be 1 to 8 groups. At this time, each group of LED lamps is controlled by one bit 70, which is not limited to the above list. In addition, the above dimming control device 100 and the dimming signal C may be set to 201208484 as suitable for other bit numbers such as 10, 16, or other bits, that is, the number of sub-dimming commands that can be extended and addressable, and dimmable Order. As the above example, it can be seen that 'using a dimming signal command c, which is decomposed into a plurality of addressable sub-dimming commands, to individually drive multiple sets of LED lamps, can greatly reduce the circuit complexity and the required circuit control for dimming control. The required quantity 'this can greatly save the construction cost of the LED lighting control system. In addition, the illumination system 10 described above can also bring a lot of practical flexibility, such as the input of the dimming command C and the number of loads K, which can have different implementations depending on the needs of the application. For example, as shown in Fig. 1, a load amount setting device 150 such as an analog, digital or mechanical switch or other circuit can be designed to input the load amount K. Further, the illumination system 1 can be designed to input a dimming command c using a dimming command input unit 160 such as a remote controller or a control panel. The load quantity setting device 150 and the dimming command input unit 160 are respectively coupled to the control unit 110 of the dimming control device 1 to input the dimming command c and the load number κ, respectively. Of course, the load setting device 150 and the dimming command input unit ι6〇 can be implemented as an integrated input device. In addition, in an example, in order to provide convenience and systematic legality, the dimming command input unit 16 can be implemented as an arithmetic device such as a computer, a handheld device, or a mobile phone, and transmits dimming through serial or parallel communication. Command C is passed to dimming control device 100 and can be extended for stylized regulation or scheduling. In another implementation, the dimming control device 100 can be implemented with a wired or wireless communication interface or communication mode = (such as 1232, leg, Bluetooth or Wi_Fi), or via the network to achieve near Or the control dimming control device of the terminal. Other embodiments of the dimming control (four) will be exemplified below.

By setting the switch 350 to set the binary value of K: Ν2ΝιΝ〇=001, the number of dimming driving signals outputted by the dimming control device 300 is set to 2, and the serial transmission is performed by the computing device 360 (such as a personal computer). The module 310 (such as the RS-232 communication module) outputs a serial signal (ie, the dimming command 0: 11010100, as shown in Fig. 4. The central processing unit 320 of the dimming control device 300 is based on the slave setting switch 201208484 TW6446PA' The number of loads obtained by 350 ~ 仏仏 = 001 is automatically determined, and the 8-bit serial signal (ie, the dimming command C) is divided into two PWM outputs as dimming drive signals. At this time, the two outputs of the dimming control device 300 are output. The dimming drive signal PWM and PWM are controlled by individual independent 4 bits, and the dimming order can be 16 steps. The period is: dimming drive signal PWM controlled by high bit B7B6B5B4=1101! The duty cycle is 81.25%, and the duty cycle of the dimming drive signal PWM controlled by the low bit ΒΑζΒΑπΟΙΟΟ is 25%, and the output is as shown in Fig. 4 and Fig. 4C. As shown in Table 1.

第四實施例 第5圖繪示依照一第四實施例之調光控制裝置。第5 201208484 圆之調光控制裝置500與第3圖中的調光控制裝置300的 主要差別在於以電路來代替中央處理單元320，作為控制 單元520。如此，控制單元520可以用數位邏輯電路，如 控制單元520所包括的位元計數器511及控制電路515， 來實現與上述中央處理單元320所作的相似的功能。如 此，實作時，可設計一晶片來實施調光控制裝置500，而 不需要使用微控制器。如此，可以降低元件數量以及簡化 實作方式，而且不需要對單晶片作程式化的動作。控制電 路515例如以邏輯電路如多工器、解工器、暫存器或其他 鲁 邏輯電路達成。而在其他例子中，串列傳輸模組510亦可 改為其他通訊模組，如USB、紅外線、無線網路。 調光控制裝置500之運作舉例如下。控制電路515偵 測負載數量K之二進位表示N2NA。之輸入。此時，例如是 使用者設定之數值，以決定調光控制裝置500所要 控制的LED燈具的組數。控制電路515依據輸入的負載數 量K，得以設定如何處理由位元計數器511所接收的調光 命令C。接著，控制電路515對PWM控制單元530作致能籲 或除能，而另一方面，控制電路515啟動串列傳輸模組 510。藉由串列傳輸模組510，位元計數器511接收到位元 數為Μ的調光命令C，並傳送到控制電路515。控制電路 515將此調光命令C，依據負載數量Κ分別輸出調光控制 訊號給PWM控制單元530,並由PWM控制單元530輸出PWM 訊號（即調光驅動訊號）。而上述串列傳輸模組510、位元 計數器511、控制電路515可回應新的調光命令C，進而 重新的設定PWM控制單元530，以隨時更新個別LED燈具 12 201208484 TW64i6PA . 的明亮度。 在上述各實施例中，雖然舉例以8位元的調光命令c 可以分解多個位元數目相同的子調光命令以便解說，但實 施方式並不以此為限，如1〇、16或其他位元亦可。在其 他例子中，8位元的調光命令c更可分解為對應至3、5、 6或7個的子調光命令，此時，各個子調光命令的位元個 數可以不同。例如負載數量K為3時，可以將8位元的調 光命令C分解為B^B。、BSB4B3、B?B6，如此可以對應地輸 馨出調光驅動訊號PWM〇、PWM!& PWM2，並且分別地提供三組 燈具有8、8及4段的調光解析度。至於負載數量κ為5、 6或7時之應用，亦可如此類推。另外，在其他例子中， 多個子調光命令的位元數目可以按需要分配，例如將8位 元的調光命令C分解為β,Β。、B5、B4BaB2、B?、Be，如此可 因應需要，將二組只需要開或關的燈具耦接到對應到子調 光命令Bs、B7、Be的輸出端，而需要更仔細的調光解析度 的兩組燈耦接到對應到子調光命令的輸出端。 如此，上述各實施例之調光控制裝置的電路資源能得以充 分利用以及提供調光上的彈性。 上述實施例可將電路部分作成專屬的晶片如以應用 專屬積體電路（Application Specific Integrated Circuit，ASIC)實作。依上述實施例亦可發展成不同的照 明控制系統，或燈具調光控制模組。 如上述各實施例可知，應用一個調光信號c，分解成 夕個可定址的調光控制信號，以個別驅動多組LED燈具， 其忐大大降低實現調光控制所需的電路複雜度以及所需 13 201208484 要的調光控制裝置數量，如此可以大幅節省led照明控制 系統的佈建費用。此外，上述實施例亦可帶來許多實作上 或應用上的彈性，可延伸及擴展多種不同的應用，如近端 或遠端、有線或無線的調光控制。若利用一運算裝置傳輸 調光命令C到調練制裝置，則可延伸應用如程式化的調 控或排程或監控燈具的明亮度。 综上所述 雖热本褐露已以實施例揭露如上，然豆並 月:本發明所屬技術領域中具有通常:識 :，在不脫離本揭路之精神和範圍内， 與潤飾。因此’本發明之 == 圍所界定者為準。 <曱吻專利範 【圖式簡單說明】 第1圖繪示使用依照 之照明系統。 第2圖繪不使用依只导 之照明系統。 第3圖繪示使用依照 之照明系統。 一第一實施例之調光控制裝置 一第二實施例之調光控制裝置 一第三實施例之調光控制裝置 第4Α圖繪示為一調光命令的例子。 第4Β及4C圖纟tv為〜 分 令後所對應的蘭驅動__子。_子狀, 第5輯示依照一第四實施例之調光控制裝置。 【主要元件符號說明】 201208484 TW6446PA ' 10、20、30 :照明系統 100、200、300、500 :調光控制裝置 110、210、520 :控制單元 120、220 :調光驅動單元 150 :負載數量設定裝置 160 :調光命令輸入單元 221_1〜221_N :調光驅動器 310、510 :串列傳輸模組 ❿ 320 :中央處理單元 330、530 : P丽控制單元 350 :設定開關 360 :運算裝置 511 :位元計數器 515 :控制電路 C:調光命令 K :負載數量 # L1〜LN:LED燈具 V_dim :調光控制訊號 15Fourth Embodiment FIG. 5 is a view showing a dimming control apparatus according to a fourth embodiment. The main difference between the fifth 201208484 circular dimming control device 500 and the dimming control device 300 in Fig. 3 is that the central processing unit 320 is replaced by a circuit as the control unit 520. As such, the control unit 520 can implement functions similar to those of the central processing unit 320 described above by digital logic circuits, such as the bit counter 511 and the control circuit 515 included in the control unit 520. Thus, in practice, a wafer can be designed to implement the dimming control device 500 without the need for a microcontroller. In this way, the number of components can be reduced and the implementation can be simplified without the need for stylized actions on a single wafer. Control circuit 515 is implemented, for example, by logic circuits such as multiplexers, demultiplexers, registers, or other logic circuits. In other examples, the serial transmission module 510 can also be changed to other communication modules, such as USB, infrared, and wireless networks. An example of the operation of the dimming control device 500 is as follows. The control circuit 515 detects that the binary number of the load K represents N2NA. Input. At this time, for example, the value set by the user determines the number of groups of LED lamps to be controlled by the dimming control device 500. The control circuit 515 sets how to handle the dimming command C received by the bit counter 511 in accordance with the input load amount K. Next, control circuit 515 enables or disables PWM control unit 530, and on the other hand, control circuit 515 activates serial transmission module 510. By the serial transmission module 510, the bit counter 511 receives the dimming command C having the bit number Μ and transmits it to the control circuit 515. The control circuit 515 outputs the dimming control signal to the PWM control unit 530 according to the number of loads 515, and the PWM control unit 530 outputs the PWM signal (ie, the dimming driving signal). The serial transmission module 510, the bit counter 511, and the control circuit 515 can respond to the new dimming command C, and then reset the PWM control unit 530 to update the brightness of the individual LED lamps 12 201208484 TW64i6PA . In the above embodiments, although the 8-bit dimming command c can be used to decompose a plurality of sub-dimming commands having the same number of bits for explanation, the implementation manner is not limited thereto, such as 1〇, 16 or Other bits are also available. In other examples, the 8-bit dimming command c can be further decomposed into sub-dimming commands corresponding to 3, 5, 6, or 7. In this case, the number of bits of each sub-dimming command can be different. For example, when the load number K is 3, the 8-bit dimming command C can be decomposed into B^B. BSB4B3, B?B6, so that the dimming drive signals PWM〇, PWM!&PWM2 can be correspondingly output, and the three sets of lamps respectively have dimming resolutions of 8, 8, and 4. As for the application when the number of loads κ is 5, 6, or 7, it can be analogized. In addition, in other examples, the number of bits of a plurality of sub-dimming commands can be allocated as needed, for example, an 8-bit dimming command C is decomposed into β, Β. , B5, B4BaB2, B?, Be, so that two sets of lamps that need only be turned on or off need to be coupled to the output terminals corresponding to the sub-dimming commands Bs, B7, Be, and need more careful dimming. The two sets of resolution lamps are coupled to the output corresponding to the sub-dimming command. Thus, the circuit resources of the dimming control device of each of the above embodiments can be fully utilized and the flexibility in dimming can be provided. In the above embodiment, the circuit portion can be made into a dedicated wafer, for example, by using an Application Specific Integrated Circuit (ASIC). According to the above embodiment, different illumination control systems or dimming control modules of the lamps can be developed. As can be seen from the above embodiments, a dimming signal c is applied and decomposed into a dimmable dimming control signal to individually drive a plurality of sets of LED lamps, which greatly reduces the circuit complexity and the circuit complexity required for implementing dimming control. Need 13 201208484 The number of dimming control devices required, which can greatly reduce the construction cost of the LED lighting control system. In addition, the above embodiments can also bring a lot of flexibility in implementation or application, and can extend and expand a variety of different applications, such as near-end or far-end, wired or wireless dimming control. If a computing device is used to transmit the dimming command C to the tuning device, extended applications such as stylized tuning or scheduling or monitoring of the brightness of the luminaire can be extended. In summary, although the thermal browning has been disclosed in the above embodiments, the present invention has the following general knowledge: it does not depart from the spirit and scope of the present invention. Therefore, the == defined by the invention is subject to the definition. <Kissing Patent Model [Simplified Schematic Description] Fig. 1 shows a lighting system in accordance with the use.
