Accompanying drawing 1 is that system described in the utility model forms schematic block diagram;
Accompanying drawing 3 is light modulation unit embodiment circuit theory schematic diagram;
Accompanying drawing 4 is a LED lamp group circuit diagram.
Embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is explained in further detail below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, described LED lamp light adjusting system control centre and a plurality of zone controller all by 485 communication interface communications, transmit dimmer command between control centre and a plurality of zone controller.The Region control implement body comprises CPU main control unit and connected light modulation unit, address selection unit, power subsystem, and the light modulation unit connects a plurality of LED lamp groups.
As shown in Figure 2, the CPU main control unit adopts intelligent chip U1 among this embodiment, and 30,31,32 pin connect 485 chip U3, communicates by letter with control centre by 485 chip U3, receives the information of control centre, according to control centre's information light modulation.Address selection unit adopts 4 toggle switch SW1, toggle switch one end ground connection, and the other end is connected with the I/O mouth of CPU main control unit respectively.4 toggle switchs have 16 address states.
Power subsystem comprises DC/DC chip U2, and its input connects the input power supply by interface J4, and conversion back output direct current 5V power supply provides power supply for CPU main control unit and other each functional circuit.
Many group dimmers can be set in the light modulation unit as required.As shown in Figure 3, light modulation unit among this embodiment comprises three groups of dimmers, and every group of dimmer connects three groups of LED lamp groups respectively, and every group of dimmer is connected to the different I/O mouth of CPU main control unit.
Among the embodiment, dimmer adopts constant current control chip IC1, IC2, IC3, each constant current control chip adjustable side 6 pin receives the pwm signal of CPU main control unit, input 1 pin connects the input power supply, positive output end 8 pin connect LED lamp group positive pole by inductance, and LED lamp group negative pole connects constant current control chip negative output terminal 2 pin; Constant current control chip positive output end and input be provided with between the power supply voltage-stabiliser tube D1, the D2 that shield, D3,, described voltage-stabiliser tube positive pole connects constant current control chip positive output end 8 pin, negative pole connects the input power supply; Be connected with current-limiting resistance R2, R5, R7 between negative output terminal and the input power supply.LED lamp group circuit diagram as shown in Figure 4.
Present embodiment adopts 4 toggle switchs, and then described light adjusting system can send corresponding 16 address states of 16 kinds of dim signals.Control centre can send dimmer command separately to the controller of different appointments like this, by control centre light modulation is unified in each zone.Also can be by constantly sending the data flow of dimmer command simultaneously to each zone controller, each zone controller all can receive all dim command signal, but each controller is only carried out the corresponding dimmer command in address with its address selection unit input, carries out light modulation according to order.Each is organized the LED lamp and realizes light modulation according to the dim signal that its zone controller sent.Different lamps then can be carried out same dimming function as long as the address is identical.The Regional Champion wants light modulation as required, only needs to set receiver address by the address input unit of one's respective area and gets final product, and need not arrive control centre and operate.Each zone controller and control centre control the realization light modulation jointly, and flexibility ratio is big.
