What are the characteristics of leds
1-10 v dimming device has two independent circuit, for a common voltage circuit, used to switch on or off to the power of the lighting equipment, the other one is low voltage circuit, which provides a reference voltage, tell lighting dimming level, 0 to 10 v dimming controller used for fluorescent lamp dimming control on before, now, because on the LED driver module and the constant power supply, and have a special control circuit, so the 0 to 10 v dimmer can also support a large number of LED light
Post-cut phase control: The rear edge control dimmer, which is made of FET or insulated gate bipolar transistor (IGBT). The MOSFET is normally used as a switch device by the cutting phase dimmer, so it is also called MOSFET dimmer, commonly known as "MOS tube". MOSFET is a full control switch that can be controlled or controlled. 2, compared with the cutting edge cutting phase dimmers, cut along the phase after dimmer application on LED lighting equipment, since there is no minimum load demand, thereby on single lighting or very small load to achieve better performance, however, very few of the MOS tube used in the dimming system, generally only make single lamp dimmer switch knob type, the small power cut after that the dimmer is not applicable to engineering
Phase 2, after the cut (RPC) MOS tubes that move light 3, 1-10 VDC, cutting edge cutting phase control dimmer power: cutting edge dimming is USES the silicon controlled rectifier circuit, since communication phase 0, the input voltage chopper, until the thyristor turn-on, the input voltage. The principle is to adjust the waveform of each half wave of alternating current, to change the effective value of alternating current, to realize the purpose of adjusting the light. The advanced optical instrument has the advantages of high adjustment precision, high efficiency, small volume, light weight and easy remote control, so it is called the thyristor dimming.
The current LED light source completely replaces the traditional type of power supply. On its way in control dimmer has what kind of, many believe this is an issue of common concern by the industry, the following is the small make up to tell you: LED dimming power supply five control dimmer way of explanation. LED light-emitting principle with traditional lighting, is to rely on p-n junction, with the power of the LED light source, because of its using different chip, current voltage parameter is different, so the internal structure and circuit wiring distribution are different; Currently, there are three kinds of LED lighting control in the market: 1, cutting phase (FPC), and thyristor dimming
