Through the above steps, the first resistance value and the second resistance value can be generated and adjusted through the variable potential module as the negative feedback of the first voltage regulator module and the second voltage regulator module, so that the first voltage regulator mode The group and the second voltage regulator module change the output voltage to drive the corresponding light-emitting module to generate a light source and brightness of the corresponding color temperature when the output voltage satisfies the response voltage of the light-emitting module.
以下配合「第3圖」及「第4圖」以實施例的方式進行如下說明，請先參閱「第3圖」，「第3圖」為應用本發明產生第一色溫的光源之電路示意圖。在實際實施上，產生第一色溫的光源之電路與產生第二色溫的光源之電路相同，其差異僅在於使用不同色溫的發光二極體，為了方便解說，在此僅以產 生第一色溫的光源之電路進行說明。如「第3圖」所示意，第一發光模組110串聯多個具有第一色溫的發光二極體310，第一穩壓模組130電性連接第一發光模組110並提供穩定的電壓，可變電位模組150以順時針旋轉及逆時針旋轉產生及調整第一電阻值及第二電阻值，其中，第一電阻值能夠作為第一穩壓模組130的負回授而改變第一穩壓模組130的輸出電壓(即：第一輸出電壓)，以便在此輸出電壓滿足第一發光模組110的響應電壓時，驅動發光二極體310產生第一色溫的光源，以及調整其光源的亮度。要補充說明的是，產生第一色溫的光源之電路與產生第二色溫的光源之電路，其可變電位模組150係共用一個可變電阻的方式來實現。 The following description will be made by way of example with reference to "Fig. 3" and "Fig. 4". Please refer to "Fig. 3" and "Fig. 3" for a circuit diagram of a light source for generating a first color temperature according to the present invention. In practical implementation, the circuit for generating the light source of the first color temperature is the same as the circuit for generating the light source of the second color temperature, and the difference is only that the light-emitting diodes of different color temperatures are used, and for convenience of explanation, only the production is made here. A circuit for generating a light source of a first color temperature will be described. As shown in FIG. 3, the first light-emitting module 110 is connected in series with a plurality of light-emitting diodes 310 having a first color temperature. The first voltage-stabilizing module 130 is electrically connected to the first light-emitting module 110 and provides a stable voltage. The variable potential module 150 generates and adjusts the first resistance value and the second resistance value by rotating clockwise and counterclockwise, wherein the first resistance value can be changed as the negative feedback of the first voltage regulator module 130 The output voltage of the first voltage stabilizing module 130 (ie, the first output voltage), so that when the output voltage satisfies the response voltage of the first light emitting module 110, the light emitting diode 310 is driven to generate the light source of the first color temperature, and Adjust the brightness of its light source. It should be additionally noted that the circuit for generating the light source of the first color temperature and the circuit for generating the light source of the second color temperature are realized by the variable potential module 150 sharing a variable resistor.
如「第4圖」所示意，「第4圖」為本發明可變電位模組之示意圖。在實際實施上，可變電位模組150可使用如「第4圖」所示意的可變電阻410來實現，所述可變電阻410具有三個接腳(即：A、B及C)，其中，接腳A可電性連接至第一穩壓模組130；接腳B可電性連接至第二穩壓模組140；接腳C則電性至接地。其中接腳A及接腳C之間的電阻值(第一電阻值)與接腳B及接腳C之間的電阻值(第二電阻值)成負相關，電阻值的大小將影響選擇驅動的發光模組(第一發光模組110或第二發光模組120)且同時改變其光源的亮度。換句話說，可使用順時針方向及逆時針方向旋轉的方式來使可變電阻410產生及調整第一電阻值及第二電阻值，以分別作為第一穩壓模組130及第二穩壓模組140的負回授，進而改變第一輸出電壓及第二輸出電壓來選擇驅動第一發光模組110或第二發光模組120，並且同步改變其光源的亮度。 As shown in Figure 4, Figure 4 is a schematic diagram of a variable potential module of the present invention. In practical implementation, the variable potential module 150 can be implemented by using a variable resistor 410 as shown in FIG. 4 having three pins (ie, A, B, and C). The pin A can be electrically connected to the first voltage stabilizing module 130; the pin B can be electrically connected to the second voltage stabilizing module 140; and the pin C is electrically connected to the ground. The resistance value (first resistance value) between the pin A and the pin C is negatively correlated with the resistance value (second resistance value) between the pin B and the pin C, and the magnitude of the resistance value will affect the selection drive. The light emitting module (the first light emitting module 110 or the second light emitting module 120) and simultaneously change the brightness of the light source. In other words, the variable resistor 410 can be used to generate and adjust the first resistance value and the second resistance value in a clockwise direction and a counterclockwise direction to respectively serve as the first voltage regulator module 130 and the second voltage regulator. The negative feedback of the module 140, thereby changing the first output voltage and the second output voltage, selectively driving the first lighting module 110 or the second lighting module 120, and synchronously changing the brightness of the light source.
綜上所述，可知本發明與先前技術之間的差異在於透過可變電位模組產生及調整第一電阻值及第二電阻值作為第一穩壓模組及第二穩壓模組的 負回授，使第一穩壓模組及第二穩壓模組改變輸出電壓，以便在輸出電壓滿足發光模組的響應電壓時，驅動相應的發光模組產生相應色溫的光源及亮度，藉由此一技術手段可以解決先前技術所存在的問題，進而達成提高調光及色溫的便利性之技術功效。 In summary, it can be seen that the difference between the present invention and the prior art is that the first resistance value and the second resistance value are generated and adjusted by the variable potential module as the first voltage regulator module and the second voltage regulator module. The negative feedback allows the first voltage regulator module and the second voltage regulator module to change the output voltage, so that when the output voltage satisfies the response voltage of the light-emitting module, the corresponding light-emitting module is driven to generate a light source and brightness corresponding to the color temperature, Therefore, the technical problem can solve the problems existing in the prior art, and further achieve the technical effect of improving the convenience of dimming and color temperature.
