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.

What ways can see LED street lights to replace the high pressure sodium lamp?

Image
Under the condition of current technology,luminous efficiency of  LED street lamp  is more than high pressure sodium lamp, it is an indisputable fact that TEK LED street lamp can reach 160 LM/W. And HPS spectrum is concentrated in the yellow area, its color temperature is low, only 2000-2500 k, and relatively high color temperature such as LED, LED street light natural white temperature of 4000-5000 k, cold white is 5000-6500 k. At the same time compared with HPS, LED street lamp with high color rendering index, close to natural light in the actual lighting, can bring a person the sense of comfort. Followed by "irradiation uniformity", although the  LED street lamp  lighting is relatively concentrated, but can be by the light path of the second design, can make the light source of lamps and lanterns presents the ideal state, realize the reasonable light distribution curve adjustment, control the distribution of light, so a...

The advantage of new style TEK LED panel light is obvious

Image
TEK  LED panel light , continue to use the reflective surface luminous technology, light after secondary reflection through high light transmittance mask projection, reduce glare, the light is more soft and comfortable to the human eye to watch not easy fatigue, particularly for students who have long time exposure to indoor lighting lighting, subway passengers or office staff. The application of the patented reflective material ensures the reflection efficiency of the light, and the original high light effect of the panel light is retained to the maximum extent. In order to guarantee the reliability of the use,   the design principle of TEK LED panel light  adhering to the "maintenance", improve heat dissipation performance, reduce the LED light failure of lights and lanterns, significantly prolong the service life of the lights and lanterns, saving the maintenance cost of lights and lanterns. TEK LED panel light is more intelligent TEK LED panel light c...

Safe travel: TEK LED high bay light illuminate the locomotive base

Image
In recent years, China's rail transportation has been developing rapidly, and many second and third-tier cities have made great efforts to build urban subway projects, which have brought convenience to people.Subway passenger traffic is large, the operation security is always the top priority, the metro management department attaches great importance to the security of the train, and TEK LED high bay light  illuminate the locomotive base, which facilitates the maintenance and maintenance of subway vehicles. Traditional lighting there exists large droop, short service life, the problem such as glare, can't use how long will be replaced, is not only the economy, and the human eye in this light, easy to produce fatigue, especially the night repair subway locomotive, a bit not careful see not clear parts fault, cause hidden trouble.Today, many subway lines use LED high bay lights , which make lighting more efficient and more efficient.Second, can improve work efficiency, the ligh...
