Energy；2. increasing a control signal wire and power supply line being parallel, signal is controlled with this and realizes the light modulation control driven to LED power
System；3. means (bluetooth, Zigbee, etc.) control power drives under conditions of not increasing control route by wireless communication
Light modulation.
But finding these three dimming modes in actual use has obvious technological deficiency: 1. thyristor controlled friendship
Although stream cuts the light modulation that can realize LED drive power on the basis of not changing existing power supply line of wave light modulation, its
Fatal defects are that light modulation consistency is poor, and power frequency stroboscopic is serious；2. the dimming mode for increasing control signal wire is although technologically advanced,
But the technology upgrading for needing control system and driving power simultaneously greatly increases the cost of system, and cannot eliminate power frequency stroboscopic
The problem of, therefore limit its popularization and application；Though not needing additionally to increase 3. the brightness adjustment control technology of communication is novel
Control signal wire, but the technology upgrading difficulty and cost of the communication function of control system and driving power are greatly increased, it is right
It is using totally unfavorable；Be not suitable for the current market demand；For this purpose, need that a kind of structure is simple, light modulation consistency is good and install/
Use/extremely convenient light modulation the intelligence control system of transformation.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of structures simply, light modulation consistency is good and installs/makes
With/intelligent control system of the transformation extremely easily based on carrier communication realization place illumination.
The object of the present invention is achieved like this:
