New description: [New technical field] This creation is about a power supply device, especially for a power supply with adjustable constant current wheel. [Prior Art] In recent years, as a result of the high luminance of the Light Emitting Diode (LED) and the development of multicolor, the LED has been gradually applied to, for example, a display light source, a traffic light, Liquid crystal display (LCD) backlights and lighting applications. Therefore, the driving method of the light-emitting diode has become one of the focuses of research and development in this field. Please refer to FIG. 1 , which is a schematic diagram of a prior art LED driving circuit. In the prior art, the plurality of light-emitting diodes 1 争 are connected in series with a current limiting resistor 12, and further, a power supply voltage 14 is simultaneously connected at the other end of each current limiting resistor 12 to limit the resistor 12 The flow mode 'drives the light string formed by the light-emitting diodes 10. However, the remaining complex LED string is connected with the power supply voltage 14 ', so its brightness must be kept constant, can not meet the environmental requirements or save the brightness of the LED 1G, so not only a lot of unnecessary sources, but also The application of the light-emitting diode K) is limited. Moreover, the current LED light string consumes electricity in the 48 volts of the town and the copper-power τ, which consumes a large amount of heat, which causes the light-emitting diode 10 to be easily damaged. In view of this, this detailed summary of the lack of H kinds of adjustable power supply k output of Wei for the county, to overcome these problems. [New content] The main purpose of this creation is to provide a set of adjustable power supply devices, which are controlled by a series of electronic switches to control the constant current of each output, so that the two materials are different. The constant current is used to transmit the same brightness, to suit various applications, and to save energy. To achieve the above objectives, the present invention provides a power supply device with adjustable constant current output, a converter, and a DC voltage converter. Turning to the constant current converter. The DC current conversion includes receiving a DC voltage signal of a to-be-converted signal as a DC voltage signal, and converting the transmission number to the LED string required to have a plurality of outputs And different currents of the DC voltage are respectively outputted to each of the output ends of the wheel. Each of the output terminals is respectively connected with a sub-switch, and each-electron_ is connected to the LED string and the control unit. The control unit controls the per-electron mosquito current to the beta level of the LED array to make the reviewer's structure and features of the creation more advanced. Step-by-step understanding and understanding 'Because of the better implementation, please refer to the detailed description, as explained later: [Embodiment] Please refer to the 2nd circle, this! The connection is integrated into the complex LED of the packaged seed crystal. Body (LED) lamp Φ 16' In this embodiment, the number of LED strings 10 is exemplified by four. This creation includes - the device 18's system, receiving - input signals, and filtering out the impurities News, to output an AC wave ", its towel is the DC carrier. The device is connected to a power factor correction device 2" power factor corrector such as receiving AC filter signal to reduce its AC current After the subharmonic, the output is to be converted. The god factor correction ^ 2 () connection - DC voltage converter 22 ' DC voltage converter 22 receives the signal to be converted to convert the signal to be converted into a DC signal. The voltage converter 22 is connected to the DC current converter 24, which has a plurality of output terminals, and receives a DC voltage signal, and converts the DC voltage signal into a light-emitting diode string 16 M398290 ν The demand end is required to be a plurality of money (four) pain Final version. This Do not even lose ten counties - Electronic coffee 26, the number of radio electronic and "Yi Yi of the four case study. The mother-to-electronic switch 26 is connected to all of the light-emitting diode strings 16 and the control unit %, and the control unit 24 controls the output of the current to the light-emitting diode string 16. For example, the control unit 28 controls one of the electronic switches to turn on or turn on, and then drive the electronic_26 output to the light-emitting diode string, the binding U, and the control unit can be controlled. Each electronic switch is wired or wirelessly connected. If it is a wireless connection, the control unit 28 can be integrated into a pole bee (·) wafer to control the electronic switch 26 by wireless transmission. The power supply device of the present invention receives the input signal, and sequentially passes the wave π, the power factor corrector 20, the DC voltage converter 22, and the DC current converter %, and after being converted, the DC power is exchanged for each of the H24 - The output terminal outputs a constant current of (4), for example, a constant current of 3 〇〇, 320, 350 mA. 'Because the control unit 28 can control the electronic switch %, one of them is turned on' or turns on" so all the light-emitting diode lamps String 16 is bound to receive only one of them

If each of the light-emitting diode strings 16 includes 24 light-emitting diodes, and the on-voltage of each of the diodes is 3.5 volts, the power consumption of each of the LED strings 16 is consumed. This is 84 volts, which is higher than the conventional technology's 48 volts, so the current is available lower and the heat output is lower, making the components less susceptible to damage. The technical focus of this creation is on the control of Xiangxiang, which can be applied to street lighting, traffic flow monitoring and household lighting. Since streetlights usually need lighting most in the middle of the night, they are not needed at all. Therefore, the design of this creation can be given different m-lights in accordance with different time periods _ 'to avoid only single n-acceptance, Cause 5 M398290 to spend too little or too little, while also saving energy. Similarly, in the traffic flow monitoring, in order to capture a clear monitoring series, the money is too bright or too small to help, and the brightness of the light to be matched at different times is different, so as long as the creation and the existing The monitoring device is matched with the material, and the control technology is more suitable. For the silk Lai _ electricity, its advantages are similar to those applied to street lamps. When the right is turned over to the family photo, when necessary, the occupants can use the wireless transmission technology to turn off the electronic switch to make the LED string. Illuminate with different brightness to achieve power saving effect. ,·‘τ' described above' This creation not only can be used to fine-tune various constant current outputs, but also can be used in different applications to save energy. The above-mentioned ones are only for the purpose of this creation--the embodiment, and the scope of the implementation of the creation is not limited to the extent that the shape, structure, characteristics and spirit of the patent specification are changed and modified. It should be included in the scope of the patent application for this creation. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic diagram of a prior art LED driving circuit.
