The function of modulating the gray value of the RGB pin in the embodiment of the present invention is achieved by the DM632 wafer. The DM632 chip has 16 output channels, each with 16-bit pulse width modulation (pwM) conduction power, and three channels controlling the color change of one RGB LED. In the embodiment of the present invention, a lamp row design of 45 RGB LEDs is taken as an example, and a DM632 wafer is required, 9 pieces. The nine DM632s are connected in series, and the control commands are transmitted in the SPI mode serial communication protocol, which constitutes the driving circuit of the lamp row.

圖5為DM632晶片工作的簡單示意圖,DCK為串列通訊 時脈,母一通道的灰度控制命令為16位元,%通道共需25ό • 位元’因此控制各顆RGB LED的燈色變化時,只需依RGB 的色碼表,預先將每一燈色的色碼值存於記憶體,將256位元 的命令依序自DAI傳入,再行下達LAT的栓鎖命令,即可達 成各顆RGB LED的燈色控制。而9顆DM632串接,所需傳 送的燈色控制命令共9x256位元。第一顆DM632的DAI接腳 接收來自主控電路板的串列命令,移位暫存器依序移位接收輸 入之位元,第一顆移位暫存器溢出後,經由Da〇接腳將指令 移入第二顆DM632,依此類推直到9顆DM632的資料傳送完 畢。圖5的REXT為LED輸出電流的設定,連接一限流電阻 5地。S0M0DE/GCK則為串列輸出模式設定或外接時脈設 疋,本發明並未使用,傳送串列命令所需的時脈直接使用主控 電路板上的微控制器晶片的SPI串列模組所提供之時脈。工 如圖4中所示之燈排電路示意圖,連接器端子主要包括曰曰 片電源5V、紅色LED 4.3V、藍綠LED 5V三組電源,及DM6= ^曰片接收來自主控電路板的控制信號線。主控電路板之電路示 意圖如圖6所示,操作介面包括按鈕及旋鈕。按鈕主要操作内' 建常用固定燈色之顯示’可循環顯示内建之燈色切換。而 少^丑之使用數,當按壓時間超過預定秒數時,其功能則切換 為党度的輕’調整方式在概軟體流糊巾綱1 明 之實施例為例,如預設之常用燈色為12色,每一 RGB lxed 6 201229420 的命令為3x16位元,以9顆DM632的設計為例,每顆DM632 控制5顆RGB LED(空出一通道未使用)’則重複9次的傳送3 xl6位元命令5次及1><16位元1次的操作,即可控制燈色的 切換。 雖然DM632的每一通道具備16位元的PWM調變能力, 但在本發明中可僅使用其中8位元,另外8個位元則做為亮度 調整用。因此以12種預設燈設為例,{桃紅,亮粉紅,青藍, 絲帶藍、大紅,玫瑰紅、深靛藍、亮紫、翠綠、海青、碧玉、 紫色},其所對應的8位元RGB色碼為 {OxFF33FF,OxFF99FF,Ox33FFFF,Ox99FF99,OxFFOOOO,〇xFF0099 • ,OxOOOOFF,Ox6600FF,OxOOFFOO,Ox〇〇FFCC,OxO〇CC66, 0x9900CC },因此12色的RGB色碼陣列命令可以定義如下。 const char R_CODE[12]={0xFF,0xFF,0x33,0x99,0xFF,0xFF,0x00,0x66,0x00, 0x00,0x00,0x99};Figure 5 is a simplified diagram of the operation of the DM632 chip. DCK is a serial communication clock. The gray level control command of the mother channel is 16 bits, and the % channel requires 25 bits. • Bits' thus control the color change of each RGB LED. Whenever, according to the RGB color code table, the color code value of each light color is stored in the memory in advance, and the 256-bit command is sequentially transmitted from the DAI, and then the LAT latch command is issued. Achieve the color control of each RGB LED. The 9 DM632s are connected in series, and the required color control commands are 9x256 bits. The DAI pin of the first DM632 receives the serial command from the main control board, and the shift register sequentially shifts the bit of the input input. After the first shift register overflows, the pin is connected via Da. Move the instruction to the second DM632, and so on until the data transfer of the 9 DM632 is completed. REXT of Fig. 5 is the setting of the LED output current, and is connected to a current limiting resistor 5 ground. S0M0DE/GCK is a serial output mode setting or an external clock setting. The present invention is not used. The clock required to transmit the serial command directly uses the SPI serial module of the microcontroller chip on the main control board. The clock provided. As shown in Figure 4, the lamp terminal circuit diagram mainly includes a chip power supply 5V, a red LED 4.3V, a blue-green LED 5V three-group power supply, and a DM6=^ chip receiving from the main control circuit board. Control signal line. The circuit diagram of the main control board is shown in Figure 6. The operation interface includes buttons and knobs. The main operation of the button is to set the display of the commonly used fixed light color to cycle through the built-in light color switch. When the pressing time exceeds the predetermined number of seconds, the function is switched to the party's light's adjustment method. For 12 colors, the command for each RGB lxed 6 201229420 is 3x16 bits. Take the design of 9 DM632s as an example. Each DM632 controls 5 RGB LEDs (empty one channel is unused), then repeats 9 transmissions. The xl6 bit command is executed 5 times and 1><16 bits once to control the switching of the lamp color. Although each channel of the DM632 has a 16-bit PWM modulation capability, in the present invention, only 8 bits can be used, and the other 8 bits are used for brightness adjustment. Therefore, with 12 preset lights as an example, {Peach Red, Bright Pink, Blue, Ribbon Blue, Red, Rose Red, Deep Indigo, Bright Purple, Green, Aquamarine, Jasper, Purple}, the corresponding 8 digits The RGB color code is {OxFF33FF, OxFF99FF, Ox33FFFF, Ox99FF99, OxFFOOOO, 〇xFF0099 • , OxOOOOFF, Ox6600FF, OxOOFFOO, Ox〇〇FFCC, OxO〇CC66, 0x9900CC }, so the 12-color RGB color code array command can be defined as follows . Const char R_CODE[12]={0xFF,0xFF,0x33,0x99,0xFF,0xFF,0x00,0x66,0x00, 0x00,0x00,0x99};

const char B_CODE[12]={OxFF,OxFF,OxFF,0x99,0x00,0x99,OxFF,OxFF,OxOO 0xCC,0x66,0xCC}; 依據按鈕之操作輸入’程式將依序讀入對應的色碼陣列, 以迴圈輸出到DM632即可控制燈排之發光燈色。控制之流程 φ 在稍後說明。 _本發明燈座另設有一操作旋紐’主要用作快速選擇所欲之 顯不燈色,依據光色之色碼顏色對照表,例如可建立128組色 碼表二旋鈕轉動一圈時被區分為128個等級,由微控制器之 A/D模組讀進’轉換成對應之色碼等級,以進行顯示燈色之快 速切換操作。 明冗度控制之操作則根據按紐之按廢時間超過預定之長度 後啟動。如前面所述,DM632晶片其pWM解析度為16位元’ 本發明則只使用其8位元來進行色彩調變,RGB三色所能調 變^色已達Θ,足以滿足各種的應用。而未使用的 8位元 進行亮度調整的功效說明如下: [〗 7 201229420 t圖7所示’ DM632的每一通道灰度控制為%位元,如 果要得到最大的亮度,此8位元應位於最高有效位元(如圖7(a) 所示)’即最左邊的8位元,而其他8位元則設為〇。但如果將 此8位元從第一最鬲有效位元開始(如圖7(b)所示),則此時的 輸出功率即降到-半。若如圖7(i)所示,置於最低有效位元的 =個bit’其顯示亮度就只有圖7⑻的256分之一了。因此當按 f時間超過-絲度,例如2秒鐘,此時程式會將目前顯二的 色碼值進行旋轉,改變各通道的輸出功率,並即時作亮度的調 ^。使用者觀察亮度的變化,滿足時即刻鬆開按鍵,擾燈即維 持所需亮度達到亮度調整功效。 ’ 圖8為主控電路板檯燈控制程式的流程圖,#1〜#3方塊為 主控晶片601基本10接腳的輸出入設定、spi串列通信模式 規^,以及初始顯示燈色的設定。本發明以8位元的^模式 通信,因此所欲顯示的C0DE陣列讀取並處理後,必須分為9 SPI接腳傳送(即傳送9X32X8位元),圖示中所標示 專送迴圈#4〜#8即負責此一功能。當命令傳送完畢後, =方塊送出栓鎖信號,如圖5或圖6之^丁所示,此時尺㈤ ^的,示控制即由DM632晶片所負責,方塊則偵測是否 鈕二\沒有按鈕操作則進入旋鈕偵測,直到有按鈕或旋 ^賴_ ’才健喊齡之命令·。_〜#14的功能 ^安J伽彳,若是短按趣,則直接將顏色陣列的㈣值加一, 到新的顏色顯示。岐按壓時間超過-預定長度,例如 的變于Γΐ ’並即時切換亮度以便觀察亮度 開,程式將持續進行亮度的循環操作。按 域、開後則再進入按鈕及旋紐的等待迴圈,即議、#17 之步驟。 你Λ若旋树操作的動作,#19依讀進的加值進行燈色等 驟得據以讀進對制燈色_值,再ί 的SPI模式傳送燈色命令到DIvI632。後再 及旋紐的等待迴圈,同前侧、#17、㈣之步=進入W丑 201229420 燈光売度的處理,是將讀進的顏色陣列依圖7的位元格式 依序處理,並將處理後的資料以SPI模式輸出到舰632即時 凋整RGB LED的亮度。只要按鈕沒放開,燈色合 從最亮慢慢變化到最不亮之9種亮度等級變化。觀g 度到合適值即可放開胁,此後檯燈即可轉在設定的亮度顯。 不〇 1' 而為了使RGB LED的三原色亮度盡可能一致,以充分調出 =欲之燈色,本發明所採用之電源設計共有三組電源,其功能 方塊圖如圖9所示。圖9中電源供應器提供5V/7A % 源’經過穩壓電路後產生電源43v/3a紅色卿 5V/3A的藍綠LED電源,主控電路板的電源額^為5v/u、。 綜上所述,本案深具產業之利用性,且杳 品及已核准之專利公告中,並未見與本發 ,者’亦合乎新穎性及進步性之法定專利申依 審查委員能早曰賜予本案專利= 申μ人之權盈。惟本案所揭露者,僅為本發明 忏 ^不能以此蚊本發明之_範圍,凡 效變更_者,仍涵蓋於树批_利=所作之等 9 1 S1 201229420 【圖式簡單說明】 第1圖全彩多功能檯燈之立體示意圖 第2圖全彩多功能檯燈之構件分解示意圖 第3圖燈排之示意圖 第4圖燈排之電路示意圖 第5圖DM632定電流晶片方塊圖 第6圖主控電路板之功能示意圖 第7圖檯燈亮度控制示意圖 第8圖全彩多功能檯燈之軟體控制流程圖 第9圖電源供應之示意方塊圖 【主要元件符號說明】 10 RGB LED 燈排 101 RGB LED 102定電流晶片 103連接器 104螺孔 20燈罩 201螺孔 30上燈桿 40下燈桿 50燈座 501燈桿通孔 502按紐通孔 503旋鈕通孔 60主控電路板 601主控晶片 602 按:is 603旋紐 70電源供應器 10Const char B_CODE[12]={OxFF, OxFF, OxFF, 0x99, 0x00, 0x99, OxFF, OxFF, OxOO 0xCC, 0x66, 0xCC}; According to the operation of the button, the program will read the corresponding color code array sequentially. The color of the light of the light row can be controlled by outputting the loop to the DM632. The flow of control φ will be explained later. _ The lamp holder of the present invention is further provided with an operation knob, which is mainly used for quickly selecting the desired color of the light. According to the color code color table of the light color, for example, 128 groups of color code tables can be established. It is divided into 128 levels, which are read into the corresponding color code level by the A/D module of the microcontroller to perform the fast switching operation of the display light color. The operation of the verbose control is started after the expiration time of the button exceeds the predetermined length. As mentioned above, the DM632 wafer has a pWM resolution of 16 bits. The present invention uses only its 8-bit color modulation, and the RGB three colors can be adjusted to meet various applications. The effect of the unused 8-bit brightness adjustment is as follows: [〗 7 201229420 t Figure 7 'The gray level control of each channel of DM632 is % bit. If you want to get the maximum brightness, this 8 bit should be Located in the most significant bit (as shown in Figure 7(a)), the leftmost 8-bit, while the other 8-bit is set to 〇. However, if the 8-bit is started from the first most significant bit (as shown in Fig. 7(b)), the output power at this time is reduced to -half. As shown in Fig. 7(i), the display of the brightness of the least significant bit = one bit is only one-half of the one-fifth of Fig. 7 (8). Therefore, when the time f exceeds the wire length, for example, 2 seconds, the program will rotate the color code value of the current display two, change the output power of each channel, and immediately adjust the brightness of the channel. The user observes the change in brightness, and when the time is satisfied, the button is released, and the disturbance light maintains the desired brightness to achieve the brightness adjustment effect. Figure 8 is a flow chart of the main control circuit board lamp control program, #1~#3 block is the main control chip 601 basic 10 pin input and output settings, spi serial communication mode regulation ^, and initial display light color settings . The invention communicates in an 8-bit mode, so after the C0DE array to be displayed is read and processed, it must be divided into 9 SPI pin transmissions (ie, 9X32X8 bits are transmitted), and the special return circle indicated in the figure# 4~#8 is responsible for this function. When the command is transmitted, the = block sends the latch signal, as shown in Figure 5 or Figure 6. At this time, the ruler (5) ^, the control is responsible for the DM632 chip, and the block detects whether the button is not \ The button operation enters the knob detection until there is a button or a rotation _ ' _~#14's function ^An J 彳, if it is short, it will directly add the (four) value of the color array to the new color display. When the pressing time exceeds - the predetermined length, for example, it changes to Γΐ ' and the brightness is switched immediately to observe the brightness, the program will continue the cycle of brightness. Press the field, then open the button and the waiting loop of the knob, that is, the step of #17. If you want to rotate the tree, the #19 is read by the added value of the light color, etc. The data is read in the _ mode, and the SPI mode is transmitted to the DIvI632. After waiting for the loop of the knob, the same as the front side, #17, (4) step = enter the W ugly 201229420, the processing of the light intensity, is to read the color array according to the bit format of Figure 7 in order, and The processed data is output to the ship 632 in SPI mode to immediately fade the brightness of the RGB LED. As long as the button is not released, the color of the lamp changes from the brightest to the least bright 9 brightness levels. The g-degree can be released to the appropriate value, and the background light can be turned to the set brightness. In order to make the RGB LED's three primary colors as uniform as possible, in order to fully recall the desired light color, the power supply design of the present invention has three sets of power supplies, and its functional block diagram is shown in FIG. In Figure 9, the power supply provides 5V/7A % source. After the voltage regulator circuit, the power supply 43v/3a red and 5V/3A blue-green LED power supply is generated. The power supply of the main control board is 5v/u. In summary, the case is deeply exploited by the industry, and the products and approved patent notices have not been seen with this issue.
