Adjusting system technology

For the development of stage light adjusting system technology, our research (simply words)is of practical value for led customer. there are has five kind of way to control LED device. see below .

* FPC （thyristor dimmer）
* RPC （MOS dimmer）
*1~10VDC dimmer
*DALI
*DMX512(or DMX)
1、FPC （thyristor dimmer）Design of the thyristor voltage regulator using synchronization sampling。Its principium is that By adjusting the connecting-angle of the booster, the single chip controls the output power of the thyristor, whose output voltage and current are detected by sample and converting circuits for sine-wave voltage control. This technology is dimming technology for high-power lamps.

2、RPC （MOSFET dimmer）
MOSFET dimmer is similar with thyristor dimmer. it also have a controller . in this work,it adopt MOSFET as switching devices. MOSFET has all control-type switching devices(Not only can open, it can colse), there are no obscure zone caused as thyristor dimmer.

3、1~10VDC dimmer
The 1~10VDC dimmer to take a more design-friendly . Through the dimmer key can adjust the incandescent light and shade degree. it just has two circuits . a road is connected with the control switch by PWM signal (In the design, to produce circuit MCU as a PWM output control signals, control of the on-switch situation,). other road is ground.

4、DALI
DALI (digital addressable lighting interface)DALI stands for Digital Addressable Lighting Interface and is a protocol set out in the technical standard IEC 62386. the DALI standard has defined an DALI network. it includes sixty-four work modules(which can be individually addressed access network.)

5、DMX512
DMX512 (Digital Multiplex) is a standard for digital communication networks that are commonly used to control stage lighting and effects. it has 8～24 road control wire can direct drive LED (RGB module) has great advantage, but it needs effective control with control signal.
