The disadvantage is that if there are more than one square in the area, the night light, but the brightness does not need to be all lights, there will be uneven regional light source. Example: In the area of ABCD group lights, when the required brightness is only half, the AC group lights are bright and the BD group lights are dark by the existing group control method. Although the BD group lamps are astigmatized after a certain height, the BD group lamps can still obviously feel insufficient brightness. The area light source is uneven. If this traditional method is used in LED lamps, in addition to the above problems, the LED lamps may be uneven due to the concentrated use of several groups of LED lamps by the user, although the LED lamps have a long life, and the failure is not as good as the conventional bulbs. It is convenient to replace the lamps. 2 The switch is equipped with a rotary switch or an extra button as the [ED lamp control. The disadvantage is that in addition to the AC power supply, the switch must pull the control line to the LED luminaire. This will cause the hydropower assembler to be bothered by the previous work habits and the number of rich luminaires is more than one. It is also assembled in a small space and the construction time is easy. Assembly error. The invention not only reduces the cost of the wire rod, but also conforms to the LED environmental protection concept', does not change the original construction mode, and does not change the user's habit of changing the brightness by changing the 201020456 switch. 3. Use LEI) brightness control with remote control. This method is convenient to construct and the user's brightness adjustment is easy', but there are still some shortcomings: 1. The production cost is high, and additional transmitting and receiving modules are needed. Second, the installation needs to pay attention to the receiving angle and distance. When there is an obstacle between the launch and the receiving (such as cement wall), the stability is reduced. Second, when there are a large number of lighting fixtures, it is not a pile of remote controls in the home, that is, the number of keys on the remote control is too complicated, which greatly reduces the willingness to use ® . SUMMARY OF THE INVENTION The present inventors have in view of the above-mentioned shortcomings of the prior art, that is, the research and development can directly use the wall switch to switch and control the brightness of the LED lamp, thereby: the set can be controlled without the need to modify the wiring in the original house to control the entire set of lamps L The ribs from the light (such as the night light) to the full light 'to achieve power-saving effect, the house lights do not need to add: the number of lamps with different functions, as long as - 盏 LED lamps can be adjusted according to user needs. ❹, [Embodiment] The present invention can be implemented by using the pulse width modulation or the current limit control. 1 ·Using PWM pulse width modulation method: Please refer to Fig. 1 , AC power supply through SW1 wall switch 1 to ac / d (electric «current circuit 2 conversion with power supply 2G, supply to single chip 3 and LED Drive circuit 4 and LED5 'in Ac/K power rectifier circuit: There is a second DC power supply 2丨 that will generate a 201020456 pulse voltage with SW, wall switch i 〇n_〇ff_〇n (as shown in Figure 2) This pulse voltage can be supplied to the MCU single chip 3 to calculate the SW! Wall switch 1 ON-〇FF_〇N times, and then can be controlled [Island 5 brightness basis, when the pulse suspension Mcu single crystal #3 internal counting circuit After 30 counts, the pulse width (such as shown in Figures 31, 3 2, and 3-3) is turned by the PMW control circuit 31, and the pulse width (bright time) is controlled at a fixed frequency, and the LED 0N can be controlled. Time, you can control the brightness, because D, D', D" is the time when the LED is on at a reference time. When the on-time is higher, the brightness of the LED is brighter. ® 2. Using the control current limit: Please refer to 4, AC power is passed through the SWi wall switch 6 to A (: / Dc power rectifier circuit 7 converts the first DC power supply 7 〇, supplied to the MCU single crystal The chip i 8 and the LED driving circuit 9 and the LED group 1 are in the AC/DC power supply rectifying circuit 7: the second DC power source 71 generates a pulse voltage when the SW1 wall switch 6 〇Ν - 〇 ρ τ 〇Ν The pulse voltage can be supplied to the MCU single chip 8 to calculate the number of SW wall switches 6 0-0-0FF-0N, and then can be used to control the brightness of the LED group 1 ,, when the pulse voltage is counted by the counting circuit in the MCU single chip 8 The D/A_conversion circuit 81 converts the voltage to a high or low voltage, and according to the voltage level, the current limiting circuit 90 in the medium driving circuit 9 can be controlled. The LED driving circuit 9 can suppress the output current at a preset value to control the LED. The brightness of the group 1〇. With the above embodiment, when the wall switch is pressed once every time 0N-0FF-0N, the LED group will change the brightness, such as continuous pressing 〇N_〇FF_〇N...the brightness of the led group is always changed. At the final point, if the brightness in the operation has been met by the user, the wall switch can be set to 0 IU and the wall switch can be turned off. Just press the switch to the OFF position, and the switch is pressed after the 〇FF position exceeds the rated time. Then 201020456 press the on position and return to the first set brightness point.
