The Lighting Control System of Intelligent Building of various modern science and technology progressively substitutes traditional lighting control mode.
LED principle of luminosity is different with traditional lighting, is lighted by P-N junction, with the LED light source of power, because it is used
Chip is different, and Current Voltage parameter is then different, therefore its internal wiring structure and circuit distribution are also different, result in each production firm
Light source exchange the requirement of optical drive and be also not quite similar, therefore control system and light source electrical equipment are mismatched also into logical in industry
Disease, while LED diversification also it is also proposed higher challenge to control system.If control system and lighting apparatus are unworthy of
Set, is likely to result in lights or flicker, and LED drive circuit and light source may be caused to damage.
Led daylight lamp power source leading edge dimmers have degree of regulation height, efficiency high, small volume, in light weight, easily remote
The advantages that manipulation, commercially occupy an leading position, the product of most producers is all this type light modulator.Leading edge phase control is adjusted
Light device typically uses controllable silicon as switching device, so also known as controllable silicon dimmer.Current many producers are using can
The dimming mode of silicon is controlled, i.e., is turned on using forward position, the mode that turns off naturally by zero crossing dims, and this dimming mode has two
The defects of individual big：
A, Electric Network Higher Harmonic interference pollution, produced in the moment of conducting.Interference can be produced to electrical equipment such as the sound equipments of family,
Also there is interference to whole power network；
B, noise, internal suppression inductance send the noise of low frequency in the moment opened, it is necessary to are subject to coming for noise insulation equipment
Processing；
Advantage is that control power is big, technology maturation, and cost is low.Some producers remove suppression inductance to save cost,
This method is very inadvisable, and the interference to ancillary equipment can be significantly increased.When serious image documentation equipment can be caused not work.

The switch of light fixture and the control of rear phase-cut dimming,
The control output unit is based on Metal-Oxide Semiconductor field effect transistor M OSFET, using soft start/soft
Shut-off measure, to reduce light fixture impact suffered in switching process.
Load current sampling unit, for control unit feedback load electric current.
Further, rear phase-cut dimming control device also includes communication interface unit, and the communication interface unit is cut after making
Phase light adjusting and controlling device obtains remote illumination control information from external bus.
Preferably, the communication interface unit is CAN interface unit.
