Embodiment
Content of the present invention is described below in conjunction with specific embodiments.
As shown in Figure 1, be the LED multichannel dimming power source apparatus structure schematic diagram of radio fest and control of the present invention.The LED multichannel dimming power source device of radio fest and control of the present invention comprises: single chip control module 10, wireless communication module 20 and constant current observing and controlling module 30.Wireless communication module 20 is connected with single chip control module 10 with constant current observing and controlling module 30.Described constant current observing and controlling module 30 comprises an independently constant current measurement and control unit 31 at least.Constant current measurement and control unit 31 comprises: PWM module (Pulse Width Modulation is abbreviated as PWM, pulse width modulation), feedback control module, LED light source module information acquisition module.LED light source module information acquisition module is realized Intelligent Measurement optical information, temperature information, telecommunications breath etc.
Control signal sends observing and controlling module coding by wireless communication module 20 to single chip control module 10, as: information coding+(opening or light or light modulation or regularly) coding.Single chip control module 10 is accepted described control signal and decodes.Corresponding constant current measurement and control unit is sent the pulse width information of open and close, timing or different duty.Pulse information is transformed to drive current information, and different duty ratio correspondences different drive currents.The drive current correspondence the brightness of LED light source module information acquisition module, accurately controls duty ratio, can accurately control light-source brightness (light modulation).Feedback control module can be so that driving current constant.
The Intelligent Measurement module detects heat, light, the telecommunications breath of LED light source module, exports to after treatment single chip control module 10.Single chip control module 10 is encoded to these metrical informations, is stored in data storage, sends to wireless communication module 20 according to control command simultaneously, sends to the observing and controlling end by wireless network.
Owing to adopting coding techniques, each constant current observing and controlling form unit can work independently, thereby realizes the LED multichannel dimming power source function of radio fest and control.
