一種控制裝置，特別有關於一種適於發光二極體的控制裝置與光源裝置。A control device, in particular, relates to a control device and a light source device suitable for a light-emitting diode.
請參考「第1圖」所示，其為一般光源裝置的示意圖。在光源裝置100中，發光二極體130(例如為紅色發光二極體)與140(例如為綠色發光二極體)會分別串聯一電阻110與120，以調整流經發光二極體130與140的電流，進而達到控制發光二極體130與140的亮度。Please refer to "Figure 1", which is a schematic diagram of a general light source device. In the light source device 100, the light emitting diode 130 (for example, a red light emitting diode) and 140 (for example, a green light emitting diode) are respectively connected in series with a resistor 110 and 120 to adjust the flow through the light emitting diode 130 and The current of 140, in turn, controls the brightness of the LEDs 130 and 140.
由於光源裝置100配置電阻110與120後，因此發光二極體130與140的亮度也會固定，因此在進行混光的應用上，發光二極體130與140所產生的混光亮度及顏色也會固定，會使得光源裝置100無法控制混合亮度及顏色。Since the light source device 100 is disposed with the resistors 110 and 120, the brightness of the light-emitting diodes 130 and 140 is also fixed. Therefore, in the application for light mixing, the brightness and color of the light-emitting diodes 130 and 140 are also mixed. It will be fixed, which will make the light source device 100 unable to control the mixed brightness and color.
若是需要調整前述的混光亮度及顏色，則需要更換電阻110與120來改變電阻值，以調整流經發光二極體130及140的電流，進而產生適當的混光亮度及顏色，但是以更換電阻110與120的方式亦會影響發光二極體130與140的原先亮度，而造成使用上的不便。因此，光源裝置仍有改善的空間。If it is necessary to adjust the aforementioned light mixing brightness and color, the resistors 110 and 120 need to be replaced to change the resistance value to adjust the current flowing through the LEDs 130 and 140, thereby generating appropriate mixed brightness and color, but to replace The manner of the resistors 110 and 120 also affects the original brightness of the light-emitting diodes 130 and 140, causing inconvenience in use. Therefore, the light source device still has room for improvement.

When the second enable signal EN2 is at a high logic level, the second control unit 270 generates a corresponding impedance value according to the impedance value corresponding to the second adjustment signal SA2, for example, the third impedance value or the fourth impedance value.

For example, when the first control signal SC1 is at a high logic level, the first LED 280 is not turned on and does not emit light. When the first control signal SC1 corresponds to the first impedance value, the first light emitting diode 280 is turned on, and generates light of the first brightness. When the first control signal SC1 corresponds to the second impedance value, the first light emitting diode 280 is turned on, and the light of the second brightness is generated. The first brightness is, for example, lower than the second brightness.
第二發光二極體290具有陽極端與陰極端，第二發光二極體290的陽極端接收工作電壓VCC，例如為P3V3_STBY，第二發光二極體290的陰極端接收第二控制訊號SC2。舉例來說，當第二控制訊號SC2為高邏輯準位時，第二發光二極體290不導通且不發光。當第二控制訊號SC2對應第三阻抗值時，第二發光二極體290導通，且產生第三亮度的光。當第二控制訊號SC2對應第四阻抗值時，第二發光二極體290導通，且產生第四亮度的光。其中，第三亮度例如低於第四亮度。The second LED 290 has an anode terminal and a cathode terminal. The anode terminal of the second LED 290 receives the operating voltage VCC, for example, P3V3_STBY, and the cathode terminal of the second LED 290 receives the second control signal SC2. For example, when the second control signal SC2 is at a high logic level, the second LED 290 is not turned on and does not emit light. When the second control signal SC2 corresponds to the third impedance value, the second LED 290 is turned on, and generates light of the third brightness. When the second control signal SC2 corresponds to the fourth impedance value, the second LED 290 is turned on, and generates light of the fourth brightness. The third brightness is, for example, lower than the fourth brightness.
藉由上述的說明，當第一發光二極體280單獨導通且發光時，第一發光二極體280產生第一亮度的光。當第二發光二極體290單獨導通且發光時，第二發光二極體290產生第三亮度的光。當第一發光二極體280與第二發光二極體290同時導通且發光時，第一發光二極體280產生第二亮度的光，第二發光二極體290產生第四亮度的光，以提供適當的混光亮度。With the above description, when the first light-emitting diode 280 is individually turned on and emits light, the first light-emitting diode 280 generates light of a first brightness. When the second light emitting diode 290 is individually turned on and emits light, the second light emitting diode 290 generates light of a third brightness. When the first light-emitting diode 280 and the second light-emitting diode 290 are simultaneously turned on and emit light, the first light-emitting diode 280 generates light of a second brightness, and the second light-emitting diode 290 generates light of a fourth brightness.

At the first end of the M1, the second logic operation unit 250 provides the second logic signal SL2 of the high logic level to the first of the second transistor M2.end.
接著，第一電晶體M1不導通，使得第一調整單元230將第一電阻R1作為第一阻抗值，以產生對應第一阻抗值的第一調整訊號SA1，且第一調整訊號SA1會傳送給第一控制單元240。同時，第二電晶體M2導通，使得第三電阻R3與第四電阻R4並聯耦接，且第二調整單元260將前述第三電阻R3與第四電阻R4並聯的阻抗值作為第三阻抗值，以產生對應第三阻抗值的第二調整訊號SA2，且第二調整訊號SA2會傳送給第二控制單元270。Then, the first transistor M1 is not turned on, so that the first adjusting unit 230 uses the first resistor R1 as the first impedance value to generate the first adjusting signal SA1 corresponding to the first impedance value, and the first adjusting signal SA1 is transmitted to The first control unit 240. At the same time, the second transistor M2 is turned on, so that the third resistor R3 is coupled in parallel with the fourth resistor R4, and the second adjusting unit 260 uses the impedance value of the third resistor R3 and the fourth resistor R4 in parallel as the third impedance value.

The two light emitting diodes 290 are such that the second light emitting diode 290 is turned on and generates light of a third brightness. Thus, when the second LED 290 is turned on alone, an appropriate luminance corresponding to the third impedance value can be generated.
此外，當第一致能訊號EN1與第二致能訊號EN2皆為高邏輯準位時，第一邏輯運算單元220會提供高邏輯準位的第一邏輯訊號SL1給第一電晶體M1的第一端，第二邏輯運算單元250會提供低邏輯準位的第二邏輯訊號SL2給第二電晶體M2的第一端。In addition, when the first enable signal EN1 and the second enable signal EN2 are both at a high logic level, the first logic operation unit 220 provides the first logic signal SL1 of the high logic level to the first transistor M1. At one end, the second logic operation unit 250 provides a second logic signal SL2 with a low logic level to the first end of the second transistor M2.
接著，第一電晶體M1導通，使得第一電阻R1與第二電阻R2並聯耦接，且第一調整單元230將前述第一電阻R1與第二電阻R2並聯的阻抗值作為第二阻抗值，以產生對應第二阻抗值的第一調整訊號SA1，且第一調整訊號SA1會傳送給第一控制單元240。同時，第二電晶體M2不導通，使得第二調整單元260將第三電阻R3作為第四阻抗值，以產生對應第四阻抗值的第二調整訊號SA2，且第二調整訊號SA2會傳送給第二控制單元270。Then, the first transistor M1 is turned on, so that the first resistor R1 and the second resistor R2 are coupled in parallel, and the first adjusting unit 230 connects the first resistor R1 and the second resistor.The impedance value of the parallel connection R2 is used as the second impedance value to generate the first adjustment signal SA1 corresponding to the second impedance value, and the first adjustment signal SA1 is transmitted to the first control unit 240.
