What are the light adjustment methods used in LED high bay light?
In recent years, countries vigorously promote wisdom urban lighting life, the replacement of traditional sodium lamp lighting system, LED high bay light that low power consumption, fast response speed, high seismic capacity, long service life, green environmental protection gradually into people's horizons, to become the most advantages instead of traditional light source of a new generation of energy-saving light source.
What are the common light dimming methods used by lighting system?
1,(FPC) controllable silicon dimming.
It is to use the silicon controlled circuit, input voltage chopper, change the sinusoidal waveform by regulating the guide angle of each half wave of alternating current, change the effective value of AC current, and then adjust the light. The advantages are high accuracy, high efficiency, small volume, light weight, easy to operate over long distance, which is the most used.
2,(RPC)MOS tube dimming.
It is made of FET or insulated gate bipolar transistor (IGBT). Mostly use MOSFET as switching devices, therefore, also known as MOSFET dimmer (MOS tube), the dimmers are all control switch, far can be controlled, the disadvantage is that move light circuit is relatively complex, stability control difficulty and higher cost.
3,DALI dimming.
Different lighting unit can be flexible grouped, implement different scene control and management, so it can be incorporated into other bus system for a subsystem used in large lighting project. TEK DALI LED high bay light is popular by factory.
4,DMX512 dimming.
The method of using standard digital interfaces from the console, invented by USITT, to control the dimmer. DMX512 is better suited to the set of lamps, such as stage lighting.
5,1-10v dimming device use two independent circuits.
Ordinary voltage circuit is used to connect or turn off the power of the lighting equipment, the low voltage control circuit provides reference voltage to realize the lighting adjustment of lamps, which can be applied to LED high bay light dimming. The disadvantage is that two lines need to be used and the construction cost is higher.
Usually we recommend factory use DALI and 0-10V dimming LED high bay light.
The traditional circuit needs to be laid with cable, which not only delays the time, but also wastes valuable copper resources. In contrast, LED high bay light is easy to operate and saves a lot of manpower and financial resources.
