Description
本發明是有關於一種電源供應系統，特別是有關於一種可對不同負載裝置輸出適當電源之電源供應系統。 The present invention relates to a power supply system, and more particularly to a power supply system that can output an appropriate power source to different load devices.
由於發光二極體(light emitting diode,LED)具有耗電量低、元件壽命長等優點，因此大量用於照明領域。 Since light emitting diodes (LEDs) have the advantages of low power consumption and long component life, they are widely used in the field of illumination.
利用發光二極體作為照明燈具時，通常是將多顆發光二極體組成陣列，以隨使用需求調整照明度。 When a light-emitting diode is used as a lighting fixture, a plurality of light-emitting diodes are usually arrayed to adjust the illumination according to the needs of use.
然而，隨著照明度的不同，燈具的功耗也隨之改變。而一般用以供應發光二極體燈具電源的電源供應器僅能輸出單一電源供應燈具所需電力，因此每一種不同功率消耗之燈具均需搭配一特定電源供應器來提供電力，如此將造成生產成本的提升。 However, as the illuminance is different, the power consumption of the luminaire changes. The power supply that is generally used to supply the power of the LED lighting can only output the power required by the single power supply. Therefore, each of the lamps with different power consumption needs to be powered by a specific power supply, which will cause production. Cost increase.
目前市面上出現一種可自適性調整電源供應的電源供應器，其原理是利用負載元件(即燈具)上串接壓差電阻，並偵測兩端壓差進行回授(feedback)來作閉迴路控制以決定電源供應器之輸出功率。然而，此種電源供應器系統複雜且成本高昂，並不適用於大量生產以應用於目前普及且價廉之發光二極體燈具上。 At present, there is a power supply that can adjust the power supply adaptively. The principle is to use a load component (ie, a lamp) to connect a differential pressure resistor in series, and detect the pressure difference between the two ends for feedback to make a closed loop. Control to determine the output power of the power supply. However, such power supply systems are complex and costly and are not suitable for mass production for use in currently available and inexpensive LED luminaires.

In the figure, the power supply system has a power supply unit 31, a resistor element 32 and a load element 33. Because of this The power supply system is detected by connecting the resistor element 32 between the power supply device 31 and the load component 33 to monitor the load state of the load component 33 at any time to output a corresponding current voltage value. Therefore, when the power supply device 31 supplies power to the load element 33, the series resistance element 32 generates additional power consumption. In addition, this detection method requires four or more lines to detect the load components and supply their power, and the system complexity is high.

請參閱第2圖，其係為本發明之電源供應系統第一實施例方塊圖。圖中，電源供應系統包含一負載模組11及一電源供應裝置12。 Please refer to FIG. 2, which is a block diagram of a first embodiment of a power supply system of the present invention. In the figure, the power supply system includes a load module 11 and a power supply device 12.

The load device 11 can be a light-emitting diode lamp, but is not limited thereto. The resistive element 112 corresponds to the load device 111. When the load module 11 with different load power consumption is selected, the resistance value of the selected resistive element 112 also corresponds to it. For example, the high-power load module 11 uses the high-resistance resistor element 112, and the low-power load module 11 uses the low-resistance resistor element 112, but is not limited thereto.
電源供應裝置12電性連接一電源13，並包含一偵測模組121、一控制模組122及一電源供應模組123。偵測模組121可為一電阻式偵測電路，用以偵測電阻元件112的電阻值並據以輸出一偵測控制訊號121a至控制模組122。其中，偵測模組121是依據所偵測不同的阻值輸出相對應的偵測控制訊號121a，且偵測控制訊號121a可為一時序脈波(clock pulse signal)。 The power supply device 12 is electrically connected to a power source 13 and includes a detection module 121, a control module 122, and a power supply module 123. The detection module 121 can be a resistive detection circuit for detecting the resistance value of the resistance element 112 and outputting a detection control signal 121a to the control module 122.

控制模組122可為一微處理器單元(Micro processing Unit,MPU)或一控制電路。控制模組122接收偵測控制訊號121a後，則輸出對應之電源控制 訊號122a至電源供應模組123。電源供應模組123接受電源控制訊號122a後，即輸出相對應的供應電源123a至負載裝置111，使負載裝置111獲得電力供應而開始工作。因此，僅需選用與負載裝置111相匹配的電阻元件112，便可使電源供應模組123輸出相應的供應電源123a至負載裝置111，而可僅用單一電源供應裝置12來匹配不同功耗的負載裝置111，以簡化生產流程及成本。其中，供應電源123a為對應發光二極體之定電流電源。此外，電阻元件112係以並聯方式與電源供應裝置12電性連接，當外部電源供應至電源供應裝置12後，偵測模組121僅需於一定時間內偵測電阻元件112之電阻值。於決定電源供應模組123之輸出功率後，便關閉偵測電路，而避免產生額外功率消耗，以達成節能效果。此外，此種電源供應裝置12僅需使用三條線路以偵測燈具負載及供應燈具電力，而可降低系統複雜度及成本。 The control module 122 can be a microprocessor unit (MPU) or a control circuit. After receiving the detection control signal 121a, the control module 122 outputs corresponding power control Signal 122a to power supply module 123. After receiving the power control signal 122a, the power supply module 123 outputs the corresponding power supply 123a to the load device 111, so that the load device 111 obtains the power supply and starts operating. Therefore, only the resistor element 112 matched with the load device 111 is selected, so that the power supply module 123 can output the corresponding power source 123a to the load device 111, and only a single power supply device 12 can be used to match different power consumption. Load device 111 to simplify production processes and costs. The supply power source 123a is a constant current power source corresponding to the light emitting diode. In addition, the resistance element 112 is electrically connected to the power supply device 12 in a parallel manner. After the external power source is supplied to the power supply device 12, the detection module 121 only needs to detect the resistance value of the resistance element 112 within a certain time. After determining the output power of the power supply module 123, the detection circuit is turned off, and additional power consumption is avoided to achieve an energy saving effect. In addition, the power supply device 12 only needs to use three lines to detect the lamp load and supply the lamp power, thereby reducing system complexity and cost.

電源供應裝置22包含一控制模組222及一電源供應模組223。控制模組222可為一微處理器控制單元(microprocessor control unit,MCU)。當電源供應裝置22接上電源23後，控制模組222則於一預設時間內傳送一電能至識別元件212，以對識別元件212充電。在此實施例中，預設時間可為5秒，電能可為一5伏特電能，但可依實際需求加以變更而不以此為限。識別元件212獲得足夠電能後，將識別訊息212a傳送至控制模組222。控制模組 222接收識別訊息212a後，便據以傳送對應識別訊息212a的電源控制訊號222a至電源供應模詛223，使電源供應模組223輸出相對應的供應電源223a至負載裝置211，而使負載裝置211獲得電力而開始工作。藉此，當電源供應裝置22搭配不同的功耗之負載裝置211時，僅需將相對應之識別訊息212a利用燒錄及傳輸載入等方式儲存於識別元件212，便可使電源供應模組223輸出相應的供應電源223a至負載裝置211，而可用單一電源供應裝置22匹配不同功耗的負載裝置211，以簡化生產流程及成本。其中，供應電源223a為對應發光二極體之定電流電源。此外，控制模組222與識別元件212之間僅需一條線路連接便可同時傳送電能/識別訊息222b。 The power supply device 22 includes a control module 222 and a power supply module 223. The control module 222 can be a microprocessor control unit (MCU). When the power supply device 22 is connected to the power source 23, the control module 222 transmits an electric energy to the identification component 212 for a predetermined time to charge the identification component 212. In this embodiment, the preset time may be 5 seconds, and the electric energy may be a 5 volt electric energy, but may be changed according to actual needs without limitation. After the identification component 212 obtains sufficient power, the identification message 212a is transmitted to the control module 222.

Therefore, when the power supply device 22 is combined with the load device 211 of different power consumption, the corresponding identification message 212a needs to be stored in the identification component 212 by means of burning and transmission loading, etc., so that the power supply module can be made. The 223 outputs the corresponding power supply 223a to the load device 211, and the single power supply device 22 can be used to match the load devices 211 of different power consumption to simplify the production process and cost. The supply power source 223a is a constant current power source corresponding to the light emitting diode. In addition, only one line connection between the control module 222 and the identification component 212 can simultaneously transmit the power/identification message 222b.
